Read MoreViagra, known generically as sildenafil, is a popular medication used to treat erectile dysfunction (ED). Getting the right dosage is crucial for effectiveness and safety. Unlike some medications where a fixed dose fits all, Viagra dosing can vary widely depending on your health, response to the drug, and other medications you might be taking.
Before starting Viagra, it’s important to understand how much to take, when to take it, and what factors influence the best dose for you. This guide will walk you through the typical dosing options and provide a handy chart for quick reference.

For most men with erectile dysfunction, the starting dose of Viagra is 50 mg taken approximately one hour before sexual activity. Depending on effectiveness and tolerability, your doctor may adjust the dose to 25 mg or increase it to 100 mg. The maximum recommended dose is 100 mg per day.
Men over 65 years old often start at a lower dose, such as 25 mg, to reduce the risk of side effects. Dosage adjustments should be made carefully under medical supervision.
For those with moderate hepatic or renal impairment, lower doses are recommended. Your healthcare provider will tailor the dose to your specific condition to avoid accumulation and adverse effects.
The typical adult dose of Viagra usually starts at 50 mg taken orally about one hour before sexual activity. Depending on your response, the dose may be decreased to 25 mg or increased to 100 mg. It’s important not to exceed one dose per day.
Viagra does not provide continuous protection or improvement in erectile function; it only works when taken before sexual activity. Timing and dose are key to achieving the best results.
Viagra is taken as needed rather than on a strict schedule. If you miss a dose, simply take it before your next planned sexual activity. Do not double the dose to make up for a missed one, as this can increase the risk of side effects.
If you have heart disease or take nitrates, Viagra is generally not recommended due to the risk of dangerous blood pressure drops. Always consult your doctor before using Viagra if you have cardiovascular issues.
Patients with kidney or liver impairment may require a lower dose or less frequent dosing. Your healthcare provider will guide you on the safest dose based on your condition.
Taking more than the recommended dose of Viagra can lead to serious side effects such as severe hypotension, prolonged erection (priapism), and vision or hearing problems. If you suspect an overdose, seek emergency medical attention immediately.
Common side effects include headaches, flushing, upset stomach, nasal congestion, and dizziness. If side effects persist or worsen, contact your healthcare provider.
Take Viagra about one hour before sexual activity, but it can be taken anywhere from 30 minutes to 4 hours prior.
Avoid excessive alcohol consumption when taking Viagra, as it can increase side effects.
Do not take Viagra with nitrates or certain other medications without consulting a doctor.
Store Viagra at room temperature away from moisture and heat.
Discuss all medications and health conditions with your healthcare provider to avoid interactions.

Viagra is typically taken as needed before sexual activity, not daily. Some patients may be prescribed daily dosing of a related medication, but this should only be done under medical supervision.
Viagra usually works for 4 to 6 hours. Its effects can vary, so timing your dose about an hour before sexual activity is recommended.
If 50 mg is not effective, your doctor may increase your dose to 100 mg. Never increase the dose on your own without consulting a healthcare professional.
Some medications, especially nitrates and certain blood pressure drugs, can interact dangerously with Viagra. Always discuss your medications with your doctor or a telehealth provider like Doctronic.ai before starting Viagra.
Viagra is not approved for use in women. Other treatments are available for female sexual dysfunction, which should be discussed with a healthcare provider.
