Who Can Take Viagra Safely in the UK?
Understanding Viagra's Onset Time
Viagra contains sildenafil citrate, a PDE5 inhibitor that works by increasing blood flow to the penis during sexual arousal. Most men experience effects within 30-60 minutes of taking the tablet, with peak effectiveness occurring around one hour. The medication can remain active in your system for 4-6 hours, though this doesn't mean erections last this entire duration.
Factors That Affect How Quickly Viagra Works
Several factors influence how long Viagra takes to work. Taking the medication on an empty stomach typically results in faster absorption, while fatty meals can delay onset by up to an hour. Individual factors such as age, overall health, and metabolism also play a role. Alcohol consumption can reduce effectiveness and delay onset, so it's best to limit alcohol when using Viagra.
Eligibility Criteria for Viagra Treatment
Viagra is suitable for adult men over 18 who experience erectile dysfunction. Before prescribing, healthcare providers assess cardiovascular health, current medications, and medical history. EverydayMeds offers both branded Viagra and generic sildenafil following consultation with UK-licensed prescribers, allowing patients to choose between options based on preference and budget.
Who Should Not Take Viagra
Certain men should not take Viagra due to safety concerns. Those taking nitrate medications for chest pain face dangerous interactions that can cause severe drops in blood pressure. Men with severe heart disease, recent heart attacks or strokes within six months, or severe liver problems should avoid this medication. Very low blood pressure and certain eye conditions also contraindicate use.
Medical Conditions That Require Caution
Some health conditions require careful consideration before starting Viagra. Men with cardiovascular disease, high or low blood pressure, liver or kidney problems may still be eligible but need medical supervision. Conditions affecting blood clotting, stomach ulcers, and certain eye problems require assessment. Your prescriber will evaluate these factors during consultation.
Dosage and Timing Considerations
Viagra is available in 25mg, 50mg, and 100mg strengths, with 50mg being the standard starting dose. The medication should be taken 30-60 minutes before sexual activity, with a maximum of one dose per 24 hours. Some men may require dose adjustments based on effectiveness and tolerability. Both Viagra and generic sildenafil are available through EverydayMeds following successful consultation.
