Understanding Viagra's Safety Profile and Guidelines
How Viagra Works Safely in Your Body
Viagra contains sildenafil citrate, a PDE5 inhibitor that works by increasing blood flow to the penis when sexually aroused. Unlike popular misconceptions, Viagra does not cause automatic erections - sexual stimulation remains necessary. The medication blocks the phosphodiesterase type 5 enzyme, allowing smooth muscle relaxation in penile blood vessels. Effects typically begin within 30-60 minutes and may last 4-6 hours, though this does not mean erections persist throughout this period.
Proper Dosage and Administration Guidelines
The standard starting dose for Viagra is 50mg, which can be adjusted to 25mg or 100mg based on effectiveness and tolerability. Take the tablet whole with water, ideally on an empty stomach for optimal absorption. Fatty meals may delay the medication's onset of action. Crucially, never exceed one dose within a 24-hour period, regardless of effectiveness. EverydayMeds offers both branded Viagra and generic Sildenafil at checkout, allowing patients to choose based on preference and budget whilst maintaining identical safety profiles.
Critical Drug Interactions and Contraindications
Viagra has several serious contraindications that make it unsuitable for certain individuals. Never combine Viagra with nitrate medications such as GTN spray or isosorbide, as this can cause dangerous blood pressure drops. Men with severe heart disease, recent heart attacks or strokes within six months, or severe liver impairment should avoid this medication. Those taking riociguat for pulmonary hypertension or alpha-blockers for prostate problems require careful medical supervision due to potential interactions.
Common Side Effects and When to Seek Help
Most men tolerate Viagra well, but some may experience mild side effects including headache, facial flushing, nasal congestion, or mild stomach upset. These typically resolve within a few hours. However, seek immediate medical attention if you experience an erection lasting longer than four hours (priapism), sudden vision or hearing loss, or chest pain during sexual activity. These rare but serious side effects require urgent medical intervention.
