How Viagra Works and What to Expect
Understanding Viagra's Mechanism
Viagra contains sildenafil citrate, a PDE5 inhibitor that increases blood flow to the penis during sexual arousal. It doesn't cause automatic erections but enhances your body's natural response to sexual stimulation. The medication blocks the phosphodiesterase type 5 enzyme, allowing blood vessels to relax and improve circulation when needed.
Timeline and Effects
Most men notice Viagra beginning to work within 30-60 minutes of taking it. The effects can last up to 4-6 hours, though this doesn't mean you'll have an erection for this entire time. You'll still need sexual stimulation for the medication to be effective. Food, particularly fatty meals, may delay how quickly Viagra starts working.
Dosage and Usage Guidelines
Viagra is typically started at 50mg, taken approximately one hour before sexual activity. Depending on effectiveness and any side effects, your prescriber may adjust this to 25mg or 100mg. It's crucial to take only one dose within any 24-hour period. EverydayMeds offers both Viagra and generic sildenafil in all three strengths.
What You Might Experience
Common effects include improved ability to achieve and maintain erections sufficient for sexual activity. Some men may experience mild side effects such as headaches, facial flushing, or nasal congestion. These typically resolve on their own and tend to become less noticeable with continued use.
Getting Started Safely
Before prescribing Viagra, our UK-licensed clinicians will assess your suitability through a comprehensive health questionnaire. This evaluation considers your cardiovascular health, current medications, and medical history to ensure Viagra is safe for you. Certain medications, particularly nitrates, can cause dangerous interactions with sildenafil.
