How Viagra Works and Getting Your Prescription
How to Order Your Repeat Viagra Prescription
If you've previously been prescribed Viagra for erectile dysfunction, ordering a repeat prescription through EverydayMeds is straightforward. Our online consultation system allows you to request your repeat treatment quickly and safely.
Start by completing our brief medical questionnaire, providing details about your current health status and any changes since your last prescription. One of our UK-licensed prescribers will review your order, typically approving repeat prescriptions within hours during working days.
At checkout, you can choose between branded Viagra tablets or generic sildenafil - both contain the same active ingredient but sildenafil offers a more cost-effective option for many patients.
Understanding How Viagra Works
Viagra contains sildenafil citrate, which belongs to a class of medicines called PDE5 inhibitors. When you become sexually aroused, your body naturally produces nitric oxide, which increases blood flow to the penis. However, an enzyme called phosphodiesterase type 5 (PDE5) can break down the chemicals responsible for this increased blood flow.
Viagra works by temporarily blocking the PDE5 enzyme, allowing increased blood flow to continue when you're sexually stimulated. This mechanism helps achieve and maintain an erection suitable for sexual activity. It's important to understand that Viagra doesn't cause automatic erections - sexual arousal is still required for the medication to be effective.
The medication typically begins working within 30-60 minutes of taking it, with effects potentially lasting 4-6 hours. This doesn't mean you'll have an erection for this entire time, but rather that you may find it easier to achieve erections during this window when sexually aroused.
Dosage and Administration
Viagra is available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, taken approximately one hour before sexual activity. Depending on effectiveness and any side effects experienced, your prescriber may adjust your dose to 25mg or increase it to 100mg.
Only take one tablet in any 24-hour period. Taking Viagra with a large or fatty meal may delay how quickly it works, so consider timing around meals. Alcohol can also affect the medication's effectiveness and may increase the risk of side effects.
Safety Considerations and Contraindications
While Viagra is generally well-tolerated, it's not suitable for everyone. You should not take Viagra if you're currently using nitrate medications (such as GTN spray for angina), as this combination can cause a dangerous drop in blood pressure.
Men with certain heart conditions, severe liver problems, very low blood pressure, or those who have recently had a stroke or heart attack may not be suitable candidates for Viagra treatment. This is why our clinical assessment is essential, even for repeat prescriptions.
Common side effects may include headaches, flushing, indigestion, nasal congestion, or dizziness. These are usually mild and temporary. However, seek immediate medical attention if you experience an erection lasting longer than four hours, sudden vision changes, or chest pain during sexual activity.
