How Does Viagra Work and What Should You Expect?
How Viagra Works in Your Body
Viagra contains sildenafil citrate, which belongs to a class of medications called PDE5 inhibitors. When you're sexually aroused, your body naturally produces nitric oxide, which increases blood flow to the penis. Viagra works by blocking an enzyme called phosphodiesterase type 5 (PDE5), which helps maintain this increased blood flow. It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still necessary for the medication to be effective.
What to Expect When Taking Viagra for the First Time
Most men find that Viagra begins working within 30-60 minutes of taking it on an empty stomach. The effects can last for 4-6 hours, though this doesn't mean you'll have an erection for this entire time. Instead, it means you may find it easier to achieve and maintain an erection when sexually aroused during this window. Taking Viagra with a large or fatty meal may delay how quickly it starts working, so timing your dose appropriately can improve effectiveness.
Dosage and Usage Guidelines
The typical starting dose for first-time users is 50mg, taken approximately one hour before sexual activity. Depending on how well you respond and whether you experience any side effects, your prescriber may adjust this to 25mg or 100mg. It's crucial to take no more than one dose in a 24-hour period. At EverydayMeds, we offer both Viagra (the branded version) and sildenafil (the generic alternative), giving you the choice between options whilst maintaining the same active ingredient and effectiveness.
Effectiveness and Success Rates
Clinical studies show that Viagra is effective for approximately 70-80% of men with erectile dysfunction. However, effectiveness can vary based on several factors including age, overall health, underlying causes of ED, and other medications you might be taking. Some men may find it works well immediately, whilst others might need to try different doses or give their body time to adjust to the medication.
Common Side Effects and What's Normal
Like all medications, Viagra can cause side effects, though not everyone experiences them. Common side effects include headaches, facial flushing, indigestion, and nasal congestion. These are usually mild and temporary. More serious side effects are rare but can include sudden vision or hearing loss, or erections lasting longer than 4 hours. If you experience any concerning symptoms, seek medical attention promptly.
Who Shouldn't Take Viagra
Viagra isn't suitable for everyone. Men taking nitrate medications (such as GTN spray for chest pain) should never take Viagra due to dangerous interactions. Those with severe heart conditions, recent stroke or heart attack, severe liver problems, or very low blood pressure may also be advised against using this medication. This is why a proper medical consultation is essential before starting treatment.
Getting Started Safely
Before taking Viagra for the first time, you'll need a consultation with a qualified prescriber who will assess your medical history, current medications, and overall health. This ensures the medication is safe and appropriate for you. At EverydayMeds, our UK-licensed clinicians provide thorough assessments to help determine if Viagra or sildenafil is suitable for your individual circumstances.
