Tadalafil is an FDA-approved medication commonly used to treat Erectile Dysfunction(ED). It is a type of drug called Phosphodiesterase Type 5 (PDE5) inhibitors, which improve blood flow to the penis, aiding in achieving and maintaining an erection. It is also approved for treating Benign Prostatic Hyperplasia (BPH) and Pulmonary Arterial Hypertension (PAH). It is available in strengths ranging from Tadalafil 2.5mg to Tadalafil 20mg; it’s typically taken orally as needed before sexual activity. Tadalafil is suitable for adult men, but those with certain medical conditions or taking specific medications should consult their doctor before using it. Common side effects include headache, indigestion, and muscle pain. It’s essential to follow Tadalafil dosage instructions, avoid overdosing, store it properly, and seek medical advice for any concerns or missed doses.
Tadalafil is a medication approved by the FDA for treating Erectile Dysfunction (ED), a condition characterized by the incapability to acquire or maintain an erection sufficient for sexual activity. It belongs to a class of drugs called Phosphodiesterase Type 5 (PDE5) inhibitors. It is also prescribed to treat symptoms of Benign Prostatic Hyperplasia (BPH) and Pulmonary Arterial Hypertension (PAH).
It comes in various strengths, typically ranging from Tadalafil 2.5mg to Tadalafil 20mg tablets. The recommended starting dose for most patients is 10 mg, taken before anticipated sexual activity, though the dosage may vary based on individual response and medical history. It should be taken orally with or without food, but avoid consuming grapefruit while using this medication.
Tadalafil is generally safe for most men, but it may not be suitable for those with certain medical conditions or taking specific medications. It’s essential to consult with a healthcare provider before starting treatment with Tadalafil, especially if you have a history of heart problems, low blood pressure, liver or kidney disease, or if you are taking nitrates for chest pain.
Common side effects of Tadalafil include headache, indigestion, back pain, and nasal congestion. Rare but serious side effects may include sudden vision loss or hearing impairment. It’s crucial to seek medical attention if you experience any severe side effects. Store Tadalafil at room temperature, away from moisture and heat, and keep it out of reach of children. Always follow your healthcare provider’s instructions and never exceed the recommended Tadalafil dosage.
Tadalafil is used for the following:
Strengths and Forms
Tadalafil is available as an oral tablet. It is found in the strengths of:
Erectile Dysfunction:
Benign Prostatic Hyperplasia: The typical dosage for Tadalafil is one 5-mg tablet per day, taken at approximately the same time daily. It’s crucial not to exceed this dosage, limiting intake to once per day to avoid potential adverse effects. If concurrently using Tadalafil with Finasteride for Benign Prostatic Hyperplasia (BPH), the recommended daily dosage remains 5 mg for a period of up to 26 weeks.
Erectile Dysfunction and Benign Prostatic Hyperplasia: The typical dosage is one 5-mg tablet per day. You should take this drug at about the same time every day. Never take more than one dose of Tadalafil a day. Sexual activity is permitted between doses at any time. To have an erection with Tadalafil, you must be sexually aroused.
Pulmonary Arterial Hypertension: The typical starting dosage is 40 mg (taken as two Tadalafil 20mg tablets) once per day. Take this dose at about the same time each day.
Tadalafil has not been studied in children. It should not be used by children under 18 years of age.
It takes your body longer to process this drug. To prevent the drug from building up too much in your body, your doctor may lower your dosage at first. It is dangerous to have too much of a drug in your body.
For People with Kidney Disease: Tadalafil is partly removed from your body through your kidneys. If your kidneys aren’t working well, more of the drug may stay in your body for extended periods of time. As a result, you are more likely to experience side effects. You may be prescribed a lower dosage, taken less often, or not at all by your doctor. Your kidney disease severity and whether you are on dialysis will determine this.
For People with Liver Disease: It is your liver that processes Tadalafil. The drug may stay in your body longer if your liver isn’t working well. As a result, you are more likely to experience side effects. Tadalafil may be prescribed to you at a lower dosage, less frequently, or not at all by your doctor. It depends on the severity of your liver disease.
[Note: Remember these recommendations may vary depending on person to person. Discuss it with your doctor, and they’ll customize your Tadalafil dosage accordingly.]
You can take the prescribed dosage of Tadalafil 20mg, usually once a day. Dosage may vary based on individual factors, so never adjust it without consulting your doctor. Take Tadalafil at approximately the same time each day for consistent blood levels. For on-demand use, take it before anticipated sexual activity. Swallow the tablet whole with water, with or without food. Do not exceed one dose per day to avoid potential side effects.
[Note: Your doctor will decide the right amount for you based on your condition, following guidelines and studies on Tadalafil. They’ll adjust it as needed over time.]
Tadalafil, a Phosphodiesterase Type 5 (PDE5) inhibitor, works by relaxing the smooth muscles in the walls of blood vessels, particularly in the penis, prostate, and lungs. By inhibiting PDE5, it increases the levels of Cyclic Guanosine Monophosphate (cGMP), a chemical messenger that promotes vasodilation and increases blood flow. Tadalafil works through different mechanisms to treat the following medical conditions:
In Erectile Dysfunction (ED), this mechanism enhances blood flow to the penis, facilitating erection.
For benign Prostatic Hyperplasia (BPH), it relaxes the muscles in the prostate and bladder, alleviating urinary symptoms.
In pulmonary Arterial Hypertension (PAH), it dilates the pulmonary arteries, reducing pulmonary vascular resistance and improving exercise capacity.
Common Side Effects
It may take a few days or a couple of weeks for these effects to disappear if they are mild. Talk to your doctor or pharmacist if they’re more severe or don’t go away.
Mild Side Effects
Adverse/Serious Side Effects
[Note: This list may not cover all possible Tadalafil side effects. Always consult with your healthcare giver for medical advice about side effects.]
Cardiovascular Risks: Tadalafil can cause a sudden decrease in blood pressure. Patients with pre-existing cardiovascular conditions should use Tadalafil with caution. It’s essential to inform your healthcare provider of any heart problems before starting Tadalafil.
Hypotension: Tadalafil may cause symptomatic hypotension in some patients. Caution is advised, especially in patients who are taking medications for hypertension or using nitrates for heart conditions, as combining these medications with Tadalafil can lead to a dangerous drop in blood pressure.
Priapism: A prolonged erection that lasts more than four hours. It is a rare but severe side effect of Tadalafil. It requires immediate medical attention to prevent tissue damage to the penis and permanent erectile dysfunction.
Vision Loss: In rare cases, Tadalafil has been associated with non-arteritic anterior ischemic optic neuropathy (NAION), a condition that can cause sudden vision loss. Patients with a history of NAION or other visual disorders should use Tadalafil with caution.
Hearing Loss: There have been rare reports of sudden hearing loss or decreased hearing in patients taking Tadalafil. If you experience any changes in hearing while taking Tadalafil, seek medical attention promptly.
Allergic Reactions: Some individuals may be allergic to Tadalafil or its inactive ingredients. Signs of an allergic reaction include inflammation, itching, swelling of the face, tongue, and lips, and difficulty breathing. Seek immediate medical attention if you experience any of these symptoms.
Use in Special Populations: Tadalafil should be used with caution in patients with kidney or liver issues, as dosage adjustments may be necessary. It is not recommended for use in individuals under 18 years of age.
Don’t take it if you’re allergic to Tadalafil. It stays in your blood for 2 days or more, longer if you have liver or kidney issues. Don’t use nitrates during this period. Before using, inform your doctor if you have any of these conditions:
Use During Pregnancy and Breastfeeding: Consult your doctor before using Tadalafil during pregnancy. It’s risky for both mother and baby, especially with pulmonary arterial hypertension. It’s uncertain if it’s safe to breastfeed while on Tadalafil. Discuss the risks with your doctor. Tadalafil for women is not recommended. It’s not approved for anyone under 18 years old.
Tadalafil is contraindicated:
If a dose of Tadalafil is missed, take it as you remember unless it’s nearly time for the next planned dose. In that case, ignore the missed dose and continue regular dosing. Refrain from doubling the dose to catch up.
[Note: If you have missed a dose of Tadalafil and are unsure about when to take the next one, immediately consult your doctor or pharmacist.]
An overdose of Tadalafil can lead to serious health complications, including severe hypotension, priapism (prolonged erection), and cardiovascular issues. Symptoms may include dizziness, fainting, chest pain, irregular heartbeat, and difficulty breathing. Immediate medical attention is crucial if an overdose is suspected.
[Note: If you consumed more than the recommended Tadalafil dosage, get medical help right away or call the Poison Help line at 1-800-222-1222.]
Tadalafil should be stored at room temperature, away from moisture, heat, and light. Keep it in its original packaging and out of reach of children and pets. Do not store Tadalafil in the bathroom or in the freezer. Ensure the medication is stored in a dry place with stable room temperature to maintain its effectiveness. Always check the expiration date and properly dispose of any expired medicines.
[Note: Discuss with your healthcare professional about the proper disposal of any unused Tadalafil and any questions you may have regarding its storage.]
[Note: This isn’t a complete list, and there could be other drugs that interact with Tadalafil. Make sure to tell your doctor about any prescription, over-the-counter medicines, and herbal products you’re taking.]
[Note: Your doctor will choose which alternative is best for you. Don’t use any of these alternative medications without consulting your healthcare provider. Taking them by yourself may cause serious side effects.]
