Understanding Viagra's Mechanism and Proper Dosing
How Viagra Works in Your Body
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 helps relax blood vessels in the penis. The enzyme PDE5 can interfere with this process by breaking down the chemicals that maintain increased blood flow.
Sildenafil blocks PDE5, allowing the natural processes to work more effectively. This results in improved blood flow to the penis during sexual stimulation. It's important to understand that Viagra does not cause automatic erections - sexual arousal is still required for the medication to work effectively.
Viagra Dosage Options and Starting Recommendations
Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with the 50mg dose, which provides an effective balance between efficacy and tolerability. Your prescriber may adjust this based on how well the medication works for you and any side effects you might experience.
The 25mg dose is typically prescribed for men who may be more sensitive to the medication or those taking certain other medicines that could interact. The 100mg dose may be considered if the 50mg dose proves insufficient, but only under medical supervision.
Timing and Administration Guidelines
Take Viagra approximately 30-60 minutes before you plan to engage in sexual activity. The medication can remain effective for up to 4-6 hours, though this doesn't mean you'll have an erection for this entire period. You should only take one dose within any 24-hour period.
Food can affect how quickly Viagra works. While you can take it with or without food, large or fatty meals may delay the onset of action. For optimal results, consider taking it on an empty stomach or after a light meal.
Branded vs Generic: Viagra and Sildenafil Options
At EverydayMeds, we offer both branded Viagra manufactured by Pfizer and generic sildenafil from licensed manufacturers. Both contain the same active ingredient in identical concentrations and work in exactly the same way. The choice between branded and generic often comes down to personal preference and cost considerations.
Generic sildenafil typically costs significantly less than branded Viagra while providing equivalent clinical effectiveness. During our online consultation, you can specify your preference, and our UK-licensed prescribers will ensure you receive the most appropriate option for your needs.
Important Safety Considerations
Before starting Viagra, it's crucial to complete a thorough medical assessment. This medication is not suitable for everyone, particularly men taking nitrate medications for heart conditions, as this combination can cause dangerous drops in blood pressure.
Common side effects may include headaches, facial flushing, indigestion, and nasal congestion. These are typically mild and temporary. However, if you experience chest pain, sudden vision loss, or an erection lasting more than 4 hours, seek immediate medical attention.
