Viagra's Effects and Important Drug Interactions
How Viagra Actually Works
Viagra contains sildenafil citrate, a PDE5 inhibitor that increases blood flow to the penis when sexually aroused. It's specifically designed to treat erectile dysfunction rather than premature ejaculation. The medication works within 30-60 minutes and its effects can last 4-6 hours, though this doesn't mean an erection lasts this duration. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil, both containing the same active ingredient with identical effects.
Does Viagra Help You Last Longer?
Whilst Viagra isn't licensed to treat premature ejaculation, some men report improved sexual performance. This may be due to increased confidence from achieving better erections, reduced anxiety about erectile function, or the ability to maintain erections more easily. However, if premature ejaculation is your primary concern, specific treatments like dapoxetine might be more appropriate. Our clinicians can discuss all available options during your consultation.
Critical Drug Interactions to Avoid
Certain medications can cause dangerous interactions with Viagra. Never take Viagra with nitrates (GTN spray, isosorbide mononitrate) as this can cause life-threatening drops in blood pressure. Other concerning interactions include riociguat for pulmonary hypertension, and caution is needed with alpha-blockers used for high blood pressure or prostate problems. Blood pressure medications, some antifungal medicines, and HIV protease inhibitors may also require dose adjustments.
Who Should Avoid Viagra
Viagra isn't suitable for everyone. Men with severe heart disease, recent heart attack or stroke, very low blood pressure, or severe liver problems should avoid this medication. Those taking recreational drugs containing nitrates ('poppers') must also avoid Viagra due to dangerous interactions. Our online consultation process thoroughly assesses your medical history and current medications to ensure safe prescribing.
Safe Usage Guidelines
Take only one dose per 24 hours, typically 30-60 minutes before sexual activity. The standard starting dose is 50mg, which can be adjusted to 25mg or 100mg based on effectiveness and side effects. Avoid large or fatty meals before taking Viagra as this can delay its effects. Always inform healthcare providers about Viagra use before starting new medications or treatments.
Choosing Between Branded and Generic
At EverydayMeds, we offer both Viagra and generic sildenafil. Both contain identical active ingredients and work exactly the same way. Generic sildenafil offers a more cost-effective option whilst maintaining the same efficacy and safety profile. Our prescribers can help you decide which option best suits your needs and budget during your consultation.
