Product Overview

Viagra is an FDA-approved brand-name medication that contains sildenafil citrate, a phosphodiesterase type 5 inhibitor. Sildenafil, its active ingredient, is used to treat erectile dysfunction by improving the flow of blood to the penis during sexual stimulation. This helps men achieve & maintain an erection suitable for sexual activity. It functions by relaxing the blood vessels (dorsal veins) in the penis, enhancing circulation.

Viagra is available in 25mg, 50mg & 100mg strengths. The recommended initial dose of Viagra is 50 mg, taken as required approximately 30 to 60 minutes before sexual activity. The dosage may be adjusted based on efficacy and tolerability but should not exceed one dose per day. Viagra is suitable for adult men with ED; however, it is not intended for individuals under 18 years or women. Its effectiveness requires sexual stimulation. Common side effects of Viagra include flushing, dizziness, headache, upset stomach, and nasal congestion. 

Rare but severe side effects of Viagra may include vision or hearing changes and prolonged erections. Avoid taking Viagra with nitrates, as this combination may lead to a potentially fatal drop in blood pressure. Individuals with cardiovascular conditions, liver or kidney issues, or certain eye disorders should consult a healthcare provider before use. If you think that the medicine is not working, it should not be doubled. In case of a Viagra overdose, seek medical attention immediately. Store the sildenafil tablets at room temperature, away from moisture and heat. Always follow your doctor’s instructions and refer to the prescription leaflet for detailed guidance.

How Does Viagra Work?

Typically, Viagra starts to work within thirty to sixty minutes after taking a dose and continues to work for up to five hours. It helps you get and maintain an erection by improving blood flow into your penis and blocking the action of phosphodiesterase type 5. Blocking the action of PDE-5 helps blood flow to the penis to occur & not be stopped by PDE-5. This also widens your blood vessels (dorsal veins) to allow more blood to flow into your penile region. If you have more questions about how Viagra works, talk with your doctor or pharmacist.

Important Safety Information for Using Viagra

What Are the Side Effects of Viagra?

Common Side Effects of Viagra: Given below are some of the most commonly occurring side effects found in people who manage ED with Viagra. These side effects are usually temporary and usually resolve on their own within a few hours or days. If they persist or become worse, talk to your doctor or healthcare provider. 

• • Headache: This is one of the most commonly occurring side effects of Viagra. It is usually mild and disappears quickly. If you experience a headache after taking this pill, it may help to lie down, rest, and turn off bright lights. If the intensity of the headache increases, you may take over-the-counter pain relief medicines such as ibuprofen or acetaminophen. 
  • Flushing: This can manifest as a temporary feeling of warmth, redness, or deepening of the skin color. You can open a window, turn on a fan, or have a cold drink to cool down. You can also lie down and rest for a few minutes. However, if you drink alcohol while experiencing flushing associated with the use of Viagra, it may become worse. 
  • Indigestion: It is possible that some individuals using Viagra may experience gastrointestinal side effects, including indigestion, diarrhea, or nausea. If Viagra upsets your stomach, you can take it with food. However, this also means that it will take more time to start functioning. To help relieve indigestion, you can use over-the-counter antacids. You can ask your doctor to recommend suitable medicine to you. 
  • Dizziness: Some users may feel dizzy after taking Viagra. To ease this side effect, lie down and rest. Once you think the dizziness has passed, get up slowly to avoid falling and hurting yourself. Drinking lots of fluids may also help. Do not consume alcohol or smoke, as they can worsen dizziness.

• Back or muscle pain: If you have backache or muscle pain after taking Viagra, resting or gentle massage may help ease the pain. If the pain is persistent or bothersome, taking an over-the-counter pain reliever may also help. Ask your pharmacist or healthcare provider to recommend you a suitable product. 

Mild Side Effects of Viagra: This medication can cause mild side effects in some people using it, which are not usually serious and do not require medical intervention. 

• Vision changes: In some cases, this medication can cause temporary vision changes, which are usually mild and go away quickly. Its symptoms include sensitivity to light, blurred vision, and a blue tinge in your vision.

• Back pain: Some users experience back pain after taking Viagra. The discomfort may result from the medication’s effect on blood vessels, causing muscle relaxation and subsequent aches. To manage this side effect, over-the-counter pain relief medicines such as ibuprofen. Additionally, gentle stretching and maintaining good posture can help alleviate discomfort. If your back pain persists or becomes bothersome, it’s advisable to consult a healthcare professional.

• Muscle Pain: Muscle aches, including those in the back and limbs, can occur due to Viagra’s vasodilatory effects, which increase blood flow and may lead to muscle discomfort.
• Nausea: Nausea is a reported side effect of Viagra and may be due to its impact on the gastrointestinal system. Taking Viagra with food can help alleviate symptoms of an upset stomach, though this might delay its onset of action. Avoiding greasy and oily food may also help.

• Dizziness: Viagra can cause a temporary drop in blood pressure, leading to dizziness or lightheadedness. To prevent this, avoid sudden movements from sitting or lying down to standing. 

Serious Side Effects of Viagra: Rarely, Viagra can cause severe side effects in some men using it. These symptoms require immediate medical assistance. If you experience any of the symptoms mentioned here, you should call your doctor or 911 immediately. To prevent serious side effects from occurring, tell your doctor if this medication is contraindicated for use or if you have any risk factors. Severe side effects include:

• Priapism: Rarely, Viagra can cause a long-lasting & painful erection. This is a medical emergency that requires to be treated immediately. If it is left untreated, priapism may damage the tissues in your penis & cause irreversible erectile dysfunction. After taking this medication, if you have an erection that lasts more than four hours, call 911 or head to the emergency room. 

• NAION: Rarely, Viagra can also lead to a severe vision-related side effect known as non-arteritic anterior ischemic optic neuropathy, a condition that can damage your optic nerve & lead to permanent vision loss. This is a medical emergency and should be treated promptly. Its symptoms include sudden vision loss in one or both eyes, sudden decrease in vision in one or both of your eyes, sudden drop in your ability to hear, or complete loss of hearing. It may also include tinnitus, and dizziness. 

• Low blood pressure: In some cases, Viagra can cause your blood pressure to fall too low, which could make you feel dizziness or lightheadedness. It could even cause you to faint. You are at an increased risk of experiencing this if you take Viagra with an alpha-blocker. Tell your doctor if you use this medication. Sometimes, this effect of Viagra can be dangerous for some people, especially for those with an existing heart condition, as it can lead to a heart attack or a stroke. Do not take Viagra if you use riociguat or other nitrate drugs. Low blood pressure, along with sexual activity, can put a lot of strain on your heart. Talk to your doctor if Viagra is safe for you to use. 

• Cardiovascular problems: Viagra can cause cardiovascular issues such as heart attack, irregular heartbeat, or stroke, particularly in individuals with pre-existing heart conditions. The medication functions by dilating blood vessels to increase blood flow, which can result in a sudden drop in blood pressure. If you have an existing heart-related condition and if you take Viagra while engaging in coitus, it can strain your heart. This can trigger adverse events like myocardial infarction or cerebrovascular accidents. To prevent this, tell your doctor before using Viagra if you have a history of heart disease, stroke, or uncontrolled high or low blood pressure. 
• Serious Allergic Reactions: Although rare, some individuals may experience serious allergic reactions to Viagra, known as anaphylaxis. This severe reaction can manifest as difficulty breathing, swelling of the face/tongue/lips/throat & severe skin rashes. A hypersensitivity response happens when the immune system mistakenly identifies sildenafil as a harmful substance, releasing chemicals that cause these symptoms. To prevent such reactions, inform your healthcare provider of any known allergies to medications before starting Viagra. If you develop signs & symptoms of an allergic reaction after taking the medication, discontinue use immediately and seek emergency medical assistance. Prompt treatment is essential, as anaphylaxis can be life-threatening if not addressed swiftly.
