How Viagra Works for Erectile Dysfunction
Understanding How Viagra and Sildenafil Work
Viagra contains the active ingredient 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 the phosphodiesterase type 5 enzyme, helping to maintain this increased blood flow and support an erection.
It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still required for the medication to be effective. The treatment typically begins working within 30-60 minutes of taking it, and its effects can last for 4-6 hours, though this doesn't mean your erection will last this long.
Switching to EverydayMeds - Simple Online Process
If you're currently taking ED medication and want to switch to our service, the process is straightforward. Start by completing our confidential online consultation form, which takes just a few minutes. Our UK-licensed clinicians will review your medical history, current medications, and assess your suitability for treatment.
During the consultation, you'll be asked about your current ED treatment, any side effects you may have experienced, and your overall health. This helps our prescribers determine the most appropriate treatment and dosage for your needs. At checkout, you can choose between branded Viagra or generic Sildenafil - both contain the same active ingredient but Sildenafil offers a more cost-effective option.
Available Dosages and Treatment Options
Both Viagra and Sildenafil are available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with a 50mg dose, which can be adjusted based on effectiveness and how well the medication is tolerated. The maximum recommended dose is 100mg, and you should never take more than one dose in a 24-hour period.
Our prescribers will recommend the appropriate starting dose based on your consultation responses. If you're switching from another ED medication, they'll consider your previous treatment experience when determining the best option for you.
Safety Considerations and Who Can Use Viagra
Viagra and Sildenafil are prescription-only medicines that require careful clinical assessment. They're suitable for adult men with erectile dysfunction, but certain health conditions and medications can make them unsuitable or require dose adjustments.
The medication cannot be prescribed if you're taking nitrate medications (such as GTN spray), have severe heart disease, very low blood pressure, or severe liver problems. Our consultation process includes thorough safety checks to ensure the treatment is appropriate for you. If you're currently taking any medications, including those for high blood pressure or heart conditions, it's essential to declare these during your consultation.
What to Expect After Starting Treatment
Most men find Viagra or Sildenafil effective for treating erectile dysfunction. The medication should be taken approximately 30-60 minutes before sexual activity, and it's best taken on an empty stomach as fatty foods can delay its effectiveness. You may experience mild side effects such as headache, flushing, or indigestion, which typically resolve on their own.
If your current dose isn't providing the desired results, or if you're experiencing side effects, our clinicians can adjust your treatment during follow-up consultations. We offer ongoing support to ensure you're getting the most from your treatment.
