Monitoring Viagra Treatment Response
Viagra's Mechanism of Action
Viagra contains sildenafil citrate, a PDE5 inhibitor that blocks phosphodiesterase type 5 enzymes. When sexually aroused, this allows increased blood flow to the penis by preventing the breakdown of cyclic GMP, a chemical that relaxes smooth muscle in penile blood vessels. This process requires sexual stimulation - Viagra does not cause automatic erections.
Timeline of Effectiveness
Most men experience Viagra's effects within 30-60 minutes of taking the tablet. Peak effectiveness typically occurs 1-2 hours after administration. The medication can remain effective for 4-6 hours, though this does not mean an erection lasts this duration. Fatty meals may delay onset by up to an hour, so taking Viagra on an empty stomach often produces faster results.
Dosage and Response Tracking
The standard starting dose is 50mg, taken approximately one hour before sexual activity. Based on effectiveness and tolerability, your prescriber may adjust this to 25mg or 100mg. Maximum frequency is once per 24 hours. Track your response over several attempts, noting timing, food intake, and effectiveness to help your clinician optimise your treatment plan.
Branded vs Generic Options
EverydayMeds offers both Viagra (branded by Pfizer) and generic sildenafil tablets. Both contain identical active ingredients and work the same way. The generic version provides the same effectiveness at a lower cost. During checkout, patients can choose between branded Viagra or generic sildenafil based on preference and budget.
What to Expect
Successful treatment varies between individuals. Some men respond well to the first dose, whilst others may need dosage adjustment or several attempts before achieving optimal results. Factors affecting response include underlying health conditions, medications, stress levels, and relationship factors. If Viagra proves ineffective after several attempts at different doses, alternative ED treatments are available.
