Viagra (Sildenafil Citrate): Patient Information

Take Viagra exactly as prescribed by your doctor. The usual starting dose is 50mg, taken as needed, about an hour before sexual activity. Your doctor may adjust this based on your response and health conditions. Never exceed the recommended dose.

Common Side Effects

Headache, flushing, nasal congestion, and visual disturbances (blurred vision, sensitivity to light) are common. These usually are mild and temporary. If they persist or worsen, contact your doctor immediately. More serious side effects, though rare, include chest pain, sudden vision loss, prolonged erection (priapism), and hearing loss. Seek immediate medical attention if you experience any of these.

Important Precautions

Viagra interacts with certain medications, particularly nitrates. Combining them can cause a dangerous drop in blood pressure. Inform your doctor about all medications you are taking, including over-the-counter drugs and supplements. If you have heart problems, high or low blood pressure, kidney or liver disease, or blood cell disorders, discuss Viagra use with your physician before starting treatment. Alcohol can worsen side effects; avoid excessive consumption.

Storage and Disposal

Store Viagra in a cool, dry place away from moisture and direct sunlight. Keep it out of reach of children and pets. Dispose of expired or unwanted medication responsibly, following your local pharmacy’s guidelines.

When to Contact Your Doctor

Contact your doctor if you experience unexpected side effects, if Viagra is ineffective, or if you have any concerns about your treatment. Regular check-ups are important to monitor your health and ensure your treatment plan remains suitable.

Understanding Viagra’s Mechanism of Action

Viagra works by increasing blood flow to the penis. This happens because it inhibits the action of an enzyme called phosphodiesterase-5 (PDE5).

PDE5 Inhibition: The Key

PDE5 normally breaks down a chemical called cyclic guanosine monophosphate (cGMP). cGMP is crucial for relaxation of the smooth muscles in the blood vessels of the penis. By blocking PDE5, Viagra allows cGMP levels to rise. This increased cGMP leads to vasodilation–widening of blood vessels–resulting in enhanced blood flow.

Sexual Stimulation Remains Necessary

It’s important to understand Viagra doesn’t directly cause an erection. Sexual stimulation is still required to trigger the release of nitric oxide, which initiates the cGMP pathway. Viagra simply enhances the effects of this naturally occurring process by prolonging the action of cGMP.

Individual Responses Vary

The effectiveness of Viagra can differ among individuals. Factors such as age, overall health, and the severity of erectile dysfunction influence how well it works. Your doctor can provide personalized advice.

Dosage, Administration, and Potential Side Effects

Sildenafil citrate, the active ingredient in Viagra, is typically taken orally as needed, about one hour before sexual activity. The recommended starting dose is 50 mg. Your doctor may adjust this based on your individual needs and response. Never exceed the maximum recommended dose of 100 mg in a 24-hour period.

Take Sildenafil with a glass of water. It can be taken with or without food, but fatty foods may slightly delay absorption.

Common side effects are usually mild and temporary. They include:

• Headache
• Facial flushing
• Nasal congestion
• Dyspepsia (indigestion)
• Visual disturbances (blurred vision, changes in color perception)

Less common, but more serious side effects require immediate medical attention and include:

• Prolonged erection (priapism)
• Sudden vision loss
• Sudden hearing loss
• Chest pain
• Irregular heartbeat

If you experience any of these serious side effects, stop taking Sildenafil and seek medical help immediately. Discuss any pre-existing medical conditions, including heart problems, with your doctor before starting Sildenafil. This medication may interact with other drugs. Always inform your doctor of all medications you are currently taking.

This information is not a substitute for professional medical advice. Always consult your doctor or pharmacist for specific instructions and to address any concerns.

Precautions, Contraindications, and Drug Interactions

Avoid Viagra if you have a history of heart problems, uncontrolled high blood pressure, or have recently had a stroke or heart attack. Always inform your doctor about all medications you are taking, including herbal supplements.

Viagra is contraindicated with nitrates (used to treat angina) due to a dangerous drop in blood pressure. Simultaneous use can lead to serious cardiovascular events.

Be cautious with alpha-blockers (for high blood pressure or prostate problems) as combined use can cause significant hypotension. Your doctor may need to adjust dosages.

Certain antifungals (like ketoconazole) and HIV protease inhibitors can increase Viagra’s levels in your blood, potentially increasing side effects. Your doctor will determine the appropriate dosage.

Avoid grapefruit juice, as it can interfere with Viagra’s metabolism, leading to higher blood levels and increased risk of side effects.

Inform your doctor about any eye problems you may have, as Viagra can rarely cause vision changes. Discuss any pre-existing liver or kidney issues, as these organs play a role in medication processing.

Sudden vision or hearing loss requires immediate medical attention. While rare, these are potential side effects of sildenafil.

Do not exceed the recommended dosage. Taking more than prescribed doesn’t enhance effectiveness and increases the risk of adverse reactions.

This information is not exhaustive. Always consult your doctor or pharmacist for personalized advice based on your individual health status and other medications you are taking.

Seeking Medical Advice and Obtaining a Prescription

Schedule a telehealth or in-person appointment with your doctor or a qualified healthcare provider. Discuss your symptoms and medical history openly and honestly. Your physician will conduct a physical examination and may order blood tests to rule out underlying health conditions.

Be prepared to answer questions about your sexual health, lifestyle, and any medications you currently take. This information helps your doctor determine if sildenafil citrate is appropriate and safe for you. Mention any heart conditions, high blood pressure, or other relevant medical issues.

If sildenafil citrate is deemed suitable, your doctor will write you a prescription. Follow their instructions precisely regarding dosage and potential side effects. Pharmacies can fill the prescription, but you may need to check if they need prior authorization from your insurance.

Understand that sildenafil citrate is not a cure for erectile dysfunction; it assists in achieving and maintaining an erection. Lifestyle changes like diet and exercise can significantly benefit overall health and sexual function. Discuss these with your doctor too.

Should you experience side effects like headaches, flushing, or visual disturbances, contact your doctor immediately. Do not exceed the prescribed dosage. Regular follow-up appointments allow your doctor to monitor your progress and adjust treatment as needed.
