When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis.

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.
Both Viagra and generic sildenafil contain identical amounts of sildenafil citrate, meaning their duration of action is the same. The effects typically last 4-6 hours, though this doesn't mean you'll maintain an erection for this entire period. Instead, it represents the window during which the medication can help you achieve an erection when sexually aroused.
The onset time is also identical - both work within 30-60 minutes of taking the tablet. Food, particularly fatty meals, may delay this timing for both branded and generic versions.
Generic sildenafil must meet the same stringent quality standards as branded Viagra in the UK. The Medicines and Healthcare products Regulatory Agency (MHRA) ensures that generic medications contain the same active ingredient, strength, and quality as their branded counterparts.
Clinical studies consistently show that generic sildenafil provides equivalent therapeutic effects to Viagra. The active ingredient - sildenafil citrate - works as a PDE5 inhibitor in both formulations, blocking the enzyme that restricts blood flow to the penis during sexual arousal.
One of the most significant differences between Viagra and generic sildenafil is cost. Generic sildenafil typically costs considerably less than branded Viagra whilst providing identical therapeutic benefits. This makes it an attractive option for men seeking long-term ED treatment.
At EverydayMeds, we offer both options during the checkout process, allowing you to choose based on your preferences and budget after completing our clinical assessment.
Both Viagra and generic sildenafil are available in three strengths: 25mg, 50mg, and 100mg tablets. The typical starting dose is 50mg, taken approximately one hour before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if the 50mg dose proves insufficient.
The maximum recommended frequency is once daily for both formulations. Taking more than one tablet within 24 hours increases the risk of side effects without improving effectiveness.
Your choice between branded Viagra or generic sildenafil may depend on several factors. Some patients prefer the reassurance of the established Viagra brand, whilst others prioritise the cost savings offered by generic alternatives.
From a medical perspective, both options are equally effective. Generic sildenafil undergoes rigorous testing to ensure bioequivalence with Viagra, meaning it's absorbed and utilised by your body in the same way.
Whether you choose Viagra or generic sildenafil, the safety profile remains identical. Both are contraindicated for men taking nitrate medications (such as GTN spray) due to dangerous blood pressure interactions. Men with severe heart conditions, recent stroke or heart attack, or severe liver problems should not use either medication.
Common side effects include headaches, facial flushing, indigestion, and nasal congestion. These typically resolve as the medication leaves your system.
It's one of the most common conditions we treat, and one of the most treatable.
