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.
Most men tolerate Viagra well, but some may experience mild side effects, particularly when starting treatment. The most frequently reported effects include headaches (affecting up to 16% of users), facial flushing, indigestion, and nasal congestion. These effects typically occur because sildenafil temporarily affects blood vessels throughout the body, not just in the penis.
Headaches can often be managed with paracetamol or ibuprofen, though you should space these at least 2 hours apart from your Viagra dose. Staying well-hydrated before taking sildenafil may help reduce headache intensity. Facial flushing usually subsides within 1-2 hours and can be minimised by avoiding alcohol and spicy foods around the time of taking your medication.
If you experience bothersome side effects with your current dose, your prescriber may recommend starting with a lower strength. Both Viagra and generic sildenafil are available in 25mg, 50mg, and 100mg tablets. Many men find that starting with 25mg reduces side effects whilst still providing effective results for erectile dysfunction.
EverydayMeds offers both branded Viagra and generic sildenafil options at checkout, allowing you to choose based on your preference and budget. The active ingredient (sildenafil citrate) is identical in both formulations, so switching between branded and generic versions may be discussed with your prescriber if needed.
Whilst serious side effects are rare, certain symptoms require urgent medical care. Seek emergency treatment if you experience an erection lasting more than 4 hours (priapism), sudden vision loss, or severe chest pain during sexual activity. These effects occur in less than 1% of men but require immediate intervention.
Contact your prescriber if you develop persistent side effects that don't improve after several doses, or if you experience unusual symptoms like severe dizziness, fainting, or difficulty breathing. Your healthcare provider can adjust your treatment plan or explore alternative ED treatments if needed.
Several practical steps can help minimise side effects from sildenafil treatment. Taking your dose on an empty stomach or after a light meal improves absorption and may reduce gastrointestinal effects. Avoiding excessive alcohol consumption (more than 2 units) can prevent additive effects on blood pressure and reduce the risk of dizziness.
Regular cardiovascular exercise, maintaining a healthy weight, and managing stress can improve your overall response to ED treatment whilst potentially reducing side effects. Many men find that side effects diminish naturally as their body adjusts to sildenafil over the first few weeks of treatment.
