Product Overview

Caverject Dual Chamber is an FDA-approved medication used to treat erectile dysfunction (ED) by directly stimulating blood flow to the penis. It contains alprostadil, a synthetic version of prostaglandin E1, which helps relax smooth muscle tissues and increases blood flow, facilitating an erection. This injectable medication is often recommended when oral medications like PDE5 inhibitors are ineffective. Caverject is available in pre-filled syringes (10 mcg and 20 mcg) and single-dose vials (20 mcg and 40 mcg), giving flexibility to patients for proper dosing and ease of use.

The dosage of Caverject is customized according to the severity and cause of ED. For most patients, the treatment starts with a low dose (typically 2.5 mcg), which can be gradually increased based on the response to the drug. The healthcare provider will carefully monitor the dosage and adjust it to find the most effective level, ensuring that the erection lasts long enough for intercourse but does not last for more than one hour. After an effective dose is determined in a clinical setting, patients can administer Caverject at home up to three times a week, ensuring at least one day between injections.

Caverject is generally well tolerated, but it may cause side effects like all medications. Common side effects include pain at the injection site, penile abnormalities, and prolonged erections (priapism), which require immediate medical attention. Caverject should only be used under the supervision of a healthcare provider, and any unusual symptoms should be reported. Polar Bear Meds offers Caverject at more affordable prices, with the option for savings through coupons, ensuring that patients can manage their condition without high costs.

What Is Caverject Used For?

• A Caverject Dual Chamber is used in the management of erectile dysfunction, addressing issues like weak erections or impotence.

What Strengths & Forms Does Caverject Come In?

Caverject (alprostadil) is available in several strengths and forms:

Pre-filled Syringes:

• 10 micrograms (mcg) 
• 20 mcg

Single-dose Vials: 

• 20 mcg of alprostadil 
• 40 mcg of alprostadil. 

[Important Note: A medically trained professional should administer the first Caverject injections in the physician’s office.]

What Is the Typical Caverject Injection Dosage?

Your healthcare provider will determine the most appropriate Caverject injection dosage for you and monitor your response to ensure optimal efficacy.

For erectile dysfunction with vasculogenic, psychogenic, or mixed etiology

• Start with an initial dose of 2.5 mcg of Caverject, injected directly into the cavernosal tissue as recommended.
• If a partial response occurs with the initial 2.5 mcg, administer an additional 2.5 mcg within one hour, using a fresh vial for each injection.
• Limit titration to no more than two doses within any 24-hour period.
• If further adjustment is necessary, increase the dosage in increments of 5 to 10 mcg, allowing at least 24 hours between adjustments.
• The target dose should facilitate an erection sufficient for intercourse without lasting beyond one hour.
• Remain under healthcare supervision until full detumescence is observed.
• Continue titration until the most effective dose is established, not exceeding 60 mcg.

For erectile dysfunction due to purely neurogenic causes (e.g., spinal cord injury)

• Begin with a dose of 1.25 mcg of Caverject, administered intracavernosally.
• If only a partial response is seen with 1.25 mcg, a second dose of 1.25 mcg may be administered within an hour, with each dose requiring a new vial.
• Further adjustments should follow the same protocol as above, with doses up to 5 mcg spaced at least 24 hours apart and not exceeding two doses in 24 hours.
• As with other etiologies, the ideal dose is one that achieves a sufficient erection for intercourse and lasts no longer than one hour.

For ongoing maintenance at home

• Once an effective dose is established in a clinical setting, occasional adjustments might be necessary after consulting with your healthcare provider.
• The recommended injection frequency should not exceed three times per week, with at least one day between injections.

In diagnosing erectile dysfunction

• Caverject may also be used diagnostically through intracavernosal injection to induce an erection and monitor its development.
• This procedure can be part of further laboratory tests such as duplex or Doppler ultrasound imaging, where a single dose sufficient to produce a rigid erection is used.

[Note: Remember, these recommendations can vary from person to person. Discuss it with your doctor, and they’ll customize your Caverject Dual Chamber dosage accordingly.]

How to Use a Caverject Dual Chamber?

Always use this medicine exactly as your healthcare provider or pharmacist has told you. Check

with your doctor or pharmacist if you are not sure. A doctor will show you how to do the injection for at least the first time. Do not try to do it yourself until you have learned the correct way, or if you cannot remember what to do, see your doctor again. These instructions are a reminder only.

• If your partner will help with preparation or injection, they should also receive training and wash their hands thoroughly.
• Remove an injection device and needle from the box.
• Peel off the foil cover and attach the needle to the device by pushing and turning it clockwise until secure.
• Remove the outer protective cap of the needle.
• Hold the device upright, turn the plunger rod clockwise to mix the powder and diluent, and gently shake until the solution is clear.
• Remove the inner protective cap carefully, ensuring the needle isn’t bent. Discard any bent needle.
• Flick the cartridge to remove large bubbles.
• Press the plunger rod to expel a few drops, ensuring the needle is primed.
• Slowly turn the end of the plunger rod clockwise to set the dose as prescribed by your doctor, indicated in the window on the device.
• Get comfortable and relax with your partner if present.
• If using an alcohol pad, clean the injection site and let it dry.
• Gently hold the penis and identify the correct injection site, avoiding veins and visible blood vessels.
• Insert the needle straight into the bulging part of the penis, as shown in your instructions.
• Push the plunger firmly but gently to administer the medication; if resistant, slightly adjust the needle, but do not force the solution.
• Withdraw the needle and massage the penis to distribute the medication.
• Dispose of the needle safely as per your doctor’s instructions.
• Do not reuse or store any leftover mixture.
• Use a new, sterile needle for each injection.
• Do not attempt to straighten or reuse a bent needle.

[Note: Your doctor will decide the right amount for you based on your condition, following guidelines and studies on the drug. They’ll adjust it as needed over time.]

How Does Caverject Work?

Caverject works by directly stimulating the blood flow into the penis to facilitate and maintain an erection. The active ingredient in Caverject, alprostadil, is a synthetic version of prostaglandin E1, a naturally occurring chemical in the body. This substance relaxes the smooth muscle tissue in the corpora cavernosa—the two cylindrical chambers in the penis that fill with blood during an erection. When injected, alprostadil increases the blood flow into these chambers. Additionally, it restricts the outflow of blood by compressing the veins, thereby helping to sustain an erection suitable for sexual intercourse.

What Are the Important Safety Information for Using Caverject?

What Are Caverject Side Effects?

Common Side Effects of Caverject: When you buy Caverject Dual online for erectile dysfunction treatment, you may experience the following side effects, which may last from a few days to several weeks:

• Pain in the Penis: Pain in the penis is one of the most frequently reported side effects of Caverject, occurring as a direct result of the injection. The pain may vary in intensity but typically subsides independently after the medication’s effects are reduced.
• Penile Abnormalities: With the long-term use of Caverject, some individuals may notice changes in the appearance of the penis, such as bruising, scarring, or the development of a bend or kink. These changes can affect the function of the penis and may require discontinuation of the Caverject.
• Prolonged Erections: Also known as priapism, this serious side effect of Caverject involves erections that last longer than four hours. This condition requires immediate medical attention to prevent damage to the penile tissues.
• Other Penile Issues: Apart from pain and structural changes, other problems such as irritation or infection at the injection site may occur using Caverject. Any unusual symptoms should be quickly discussed with a healthcare provider.
• Swelling and Skin Discoloration at the Injection Site: Initially, you might notice swelling, bruising, or a change in skin color when Caverject is administered. These symptoms are generally mild and tend to decrease with subsequent uses as you become more accustomed to the injection technique.
• Muscle Spasms: Some users of Caverject may experience involuntary muscle contractions, which can be uncomfortable. These spasms may occur anywhere in the body but are generally temporary and manageable.
• Cold and Flu Symptoms: In addition to localized reactions, users may report symptoms akin to those of a common cold or the flu, including congestion, sore throat, and malaise. While these symptoms may cause discomfort, they are typically manageable at home with standard over-the-counter remedies and adequate rest.

Serious Side Effects of Caverject: Although rare, serious side effects can occur when you use Caverject. This includes:

• Injection Site Reactions: After administering Caverject, the injection area may become notably irritated or inflamed. Symptoms can include itching, bleeding, numbness, warmth, tenderness, or pain, indicating a local reaction to the medication.
• Genital Discomfort: Users may experience redness, swelling, or pain in the testes or scrotum. Additionally, lumps known as spermatoceles, which are cysts filled with sperm, may develop. There could also be a sensation of numbness affecting the penis.
• Erection and Ejaculation Changes: Some individuals may encounter unusually uncomfortable, painfully prolonged erections or, the opposite, a lack of erection. Changes in ejaculation or issues such as a tight or swollen foreskin, as well as swelling in the head of the penis, are potential complications.
• Urinary Issues: There might be an increased urgency or frequency in the need to urinate, accompanied by pain or difficulty during urination. Blood may be present in the urine or at the end of the penis, especially if Caverject Dual Chamber is mistakenly injected into the urethra.
• General Discomfort and Infection Symptoms: Users may report pelvic pain, general weakness, excessive sweating, nausea, or swelling in the legs or arms. Symptoms resembling those of a common cold or dry mouth could surface. Additionally, there is a possibility of developing a yeast infection (thrush).
• Skin and Sensory Reactions: Side effects could include itching, a rash, redness at the injection site, or unusual skin growth. Increased sweating, sensitivity to bright light, pupil dilation (blown pupil), altered tactile sensations, leg cramps, cold extremities, and venous issues such as bleeding from veins are also possible.
• Blood Test Abnormalities: Increased creatinine levels, a substance found in muscles, might be detected during blood tests after using Caverject.

[Note: Remember, this list may not cover all possible side effects. Always consult with your healthcare giver for medical advice about side effects.]

Are There Any Warnings for Caverject?

Before initiating treatment with Caverject Dual Chamber, it is essential to discuss your health background with your doctor or pharmacist, particularly if you have any of the following conditions:

• Respiratory, cardiac, or chest-related disorders: Engaging in sexual activity may require extra caution if you have any conditions affecting your lungs, heart, or chest.
• A history of mental health issues or substance addiction: It is vital to inform your healthcare provider if you have experienced mental health disorders or have a history of addiction, as these could influence your treatment plan.
• Past occurrences of mini-strokes: These events signify potential cerebral vascular issues, necessitating careful medical supervision.
• Presence of cardiovascular risk factors: If you have high blood pressure, use tobacco, have elevated blood glucose or cholesterol levels, or struggle with being overweight or obese, these factors can significantly impact your heart health.
• Risk factors associated with stroke: These include but are not limited to high blood pressure, elevated cholesterol levels, coronary artery disease, heart arrhythmias, and diabetes. Each of these conditions could increase your risk of stroke. 

What Are the Caverject Precautions?

When considering the use of Caverject, it’s important to be aware of specific precautions and safety measures to ensure effective and safe usage. Here’s a detailed breakdown of the essential precautions you should be aware of:

• • Risk of Sexually Transmitted Diseases (STDs): Caverject Dual Chamber does not provide protection against sexually transmitted diseases (STDs) such as AIDS, herpes, or gonorrhea. When Caverject is injected, there is a minor possibility of bleeding at the injection site. This bleeding could potentially increase the risk of transmitting or acquiring STDs. Using condoms is recommended as they can help protect against STDs. It’s advisable to consult with your doctor for advice on contraception or “safe sex” practices to further reduce these risks.
  • Considerations for Pregnancy and Breastfeeding: Caverject can be safely used by couples trying to conceive and is also safe if your partner is pregnant or breastfeeding. However, it’s crucial to note that Caverject does not offer any protection against pregnancy. Couples not intending to conceive should use a reliable method of contraception to prevent unwanted pregnancies.

• Ingredients and Potential Allergies:

• • Benzyl Alcohol: Caverject Dual Chamber contains 8.9 mg/ml of benzyl alcohol, which may cause allergic reactions in some individuals. High doses of Caverject could lead to an accumulation of benzyl alcohol in the body. This accumulation can result in metabolic acidosis, a condition characterized by an increase in acid levels in your blood. Individuals with liver or kidney disease should use this medication with caution and always consult their doctor.
  • Sodium Content: This medication contains less than 1 mmol sodium (23 mg) per dose, making it essentially ‘sodium-free.’ This low sodium content is generally safe for those monitoring their sodium intake, including individuals with hypertension or heart disease.

• Not Suitable for Children: Due to the presence of benzyl alcohol and the specific adult indication of the drug, Caverject is not suitable for children. In young children, benzyl alcohol can lead to severe side effects, including the rare but serious “gasping syndrome,” which involves severe breathing difficulties.

What Are the Contraindications of Caverject?

Avoid using a Caverject Dual Chamber in the following cases:

• If you are allergic to alprostadil or any other ingredients in this medication.
• If you have sickle cell anemia, leukemia, multiple myeloma, or any condition that increases the risk of priapism—a prolonged erection lasting more than 6 hours.
• If you have a penile implant.
• If you have severe heart disease or any other condition where sexual activity is inadvisable.
• If your penis is scarred, bent, kinked, or if you have Peyronie’s disease.
• If you have a tight foreskin.

What If You Miss a Dose of Caverject?

If you realize you’ve missed a dose of Caverject, administer it as soon as you remember. However, if it’s nearly time for your next scheduled dose, skip the missed dose and continue with your regular dosing plan. Do not take a double Caverject dose to make up for the one you missed. If you’re uncertain about adjusting the Caverject dosing schedule after a missed dose, it’s important to consult your doctor or pharmacist immediately for guidance.

[Note: If you have missed a medication dose and are unsure when to take the next one, immediately consult your doctor or pharmacist.]

What Happens If You Take Too Much of a Caverject?

In the event that you administer more Caverject Dual Chamber than prescribed, contact your doctor immediately. Overdosing may require medical intervention, especially if you experience an erection that persists for more than four hours, as this may necessitate urgent treatment. For any additional questions regarding the use of this medication or the implications of an overdose, you should consult your healthcare provider or pharmacist for detailed advice.

[Note: If you consumed more than the recommended dose, get medical help right away, or call the Poison Help line at 1-800-222-1222.]

How to Store Caverject?

When you buy Caverject online from Canada, you should follow these storage instructions:

• Always store the medication in an inaccessible location to children to ensure safety.
• Avoid using the medicine beyond its expiration date, which can be found clearly marked as ‘EXP’ on the outer carton.
• Consult the storage guidelines specified on the outer carton to maintain the integrity of the medicine.
• You may prepare your injection 24 hours in advance, but ensure it is stored at or below 25°C during this time.
• Do not dispose of the medication in wastewater or household trash. For environmentally safe disposal of unused medicines, seek guidance from your pharmacist.

[Note: Discuss with your healthcare professional the proper disposal of unused medicine and any questions you may have regarding its storage.]

What Medications Interact with Caverject?

If you are looking to buy Caverject Dual online, you should consider the following drug interactions:

• Apomorphine: Combining with Caverject might enhance the potential for hypotension or low blood pressure due to their synergistic vasodilatory effects.
• Avanafil: Using avanafil with Caverject might increase the risk of priapism (prolonged and painful erection) and hypotension due to enhanced erectile function.
• Dexmedetomidine: This may enhance the hypotensive effect of Caverject due to central sympathetic inhibition.
• Hydralazine: Might exacerbate hypotensive effects when used with Caverject; close monitoring of blood pressure is advised.
• Iloprost: Similar to epoprostenol, the combination with Caverject could result in significant hypotension.
• Minoxidil Topical: Using Caverject may enhance hypotensive response due to their combined effects on blood vessels.
• Pentoxifylline: The vasodilatory effects of both could be enhanced when used together.
• Phentolamine: This combination with Caverject can excessively lower blood pressure and increase the risk of priapism.
• Sildenafil, Tadalafil, Vardenafil: These PDE5 inhibitors, when used with Caverject, have a profound risk of priapism and severe hypotension.

What Are the Other Caverject Interactions?

Apart from several Caverject drug interactions, this medication has other interactions as follows:

• Interaction with Food: Certain foods can interfere with the effectiveness of medications. For Caverject, while food interactions are not directly reported, consult your healthcare provider about any dietary restrictions.
• Interaction with Alcohol: Alcohol consumption while using Caverject may increase the risk of side effects such as dizziness, low blood pressure, and fainting. It is advisable to limit or avoid alcohol during treatment.
• Interaction with Tobacco: Smoking or using tobacco products may impact blood flow, which is directly related to the medication’s effectiveness. Discuss the use of tobacco with your healthcare provider.
• Disease Interactions: Caverject (alprostadil) has three significant disease interactions that require careful attention to ensure safe and effective use. This includes:
  • Interaction with Respiratory Distress Syndrome: Alprostadil injections are not recommended for neonates with respiratory distress syndrome. Approximately 10–12% of neonates with congenital heart defects treated with alprostadil may experience apnea. Respiratory function must be closely monitored throughout treatment. Alprostadil should only be used in settings where ventilatory support is readily available.
  • Interaction with Bleeding: Alprostadil can inhibit platelet aggregation, which may increase the risk of bleeding. Caution is advised when using this medication in neonates or patients with bleeding tendencies or coagulation disorders.
  • Interaction with Hypotension: Increased levels of prostaglandin E1 (PGE1) and its metabolites, resulting from intracavernous alprostadil injections, can lead to significant drops in blood pressure (hypotension) or dizziness. Patients with pre-existing low blood pressure or those prone to fainting (syncope) should use this medication cautiously. Blood pressure should be monitored before, during, and after administration to prevent adverse outcomes.

[Note: This isn’t a complete list, and there could be other drugs that interact with Caverject. Make sure to tell your doctor about any prescription, over-the-counter medicines, and herbal products you’re taking.]

What Are the Caverject Alternatives?

If you’re looking for alternatives to Caverject, several options are available, depending on the type and severity of the condition. Here are some Caverject alternatives:

• Viagra (sildenafil)
• Cialis (tadalafil)
• Levitra (vardenafil)

Frequently Asked Questions

How often can you use a Caverject Dual Chamber?

Caverject Dual Chamber should not be used more than once in a 24-hour period. Additionally, it is recommended that you limit the use of this medication to no more than three times per week. To minimize the risk of injury or complications, it is important to rotate the injection site. Each time you inject, ensure that you change the specific location and side of the penis to avoid repeated use of the same area. This helps in preventing irritation or damage to the tissue from frequent injections.

How long does Caverject take to work?

After injecting Caverject Dual Chamber, it may take some time for the medication to produce an erection. The onset of the erection depends on the dose, and with the correct amount, you should experience a strong enough erection to engage in sexual activity with your partner. Typically, the erection should not last longer than one hour. If you find that the erection persists for longer than desired, you should consult your doctor for adjustments. In rare cases, if the erection lasts more than four hours, it is considered a medical emergency, and you should look for immediate medical attention to avoid potential complications.

What is the difference between Caverject and Muse?

Caverject and Muse are both medications used to treat erectile dysfunction, but they differ significantly in their form and method of administration. Caverject is a medication that comes in the form of an injection, which is administered directly into the spongy tissue of the penis. The injection helps to increase blood flow to the area, resulting in an erection. On the other hand, Muse is a urethral suppository, meaning it is inserted into the urethra, the opening at the tip of the penis. When inserted, Muse dissolves and releases medication that enhances blood flow, similarly promoting an erection. The key difference lies in the way the medication is delivered: Caverject involves an injection into the penis, while Muse requires insertion into the urethra.

Is a Caverject injection painful?

The Caverject injection is generally not considered very painful, but some discomfort may occur during the process. To administer the injection, you will insert the needle into the side of the penis using a sharp thrust, pushing it into its full depth. While this initial insertion may cause slight discomfort, a firm and rapid thrust tends to minimize the pain associated with the needle’s entry. Once the needle is in place, you may feel a mild pricking sensation when the medication is injected, but this is not unusual and typically subsides quickly. Overall, the injection might cause some temporary discomfort, but it is usually manageable and does not lead to significant pain.

Does Caverject increase size?

Caverject does not increase the size of your penis, and it is not designed to do so. It is a treatment for erectile dysfunction (ED) that helps you achieve & maintain an erection when sexually aroused. Caverject works by introducing alprostadil into the penile tissue, which helps relax the blood vessels, allowing for increased blood flow. However, it does not have any effect on your natural size or cause a permanent enlargement. 

Can I use Viagra with Caverject?

While it is technically possible to use Viagra (sildenafil) with Caverject, combining these two medications should only be done under the strict guidance of a healthcare provider. Viagra is a medicine used to treat erectile dysfunction by inhibiting the enzyme phosphodiesterase-5, which helps increase blood flow to the penis. When used alongside Caverject, which is an alprostadil injection that helps dilate blood vessels in the penis, there could be an enhanced blood pressure-lowering effect. This combination may lead to a greater risk of side effects, including lower blood pressure, dizziness, or fainting. Therefore, always consult with your doctor before combining these treatments to ensure safety and effectiveness.
