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.
Sildenafil 50mg works by inhibiting the PDE5 enzyme, which increases blood flow not only to the penis but throughout your body's blood vessels. This vasodilation effect can cause mild headaches in some men, particularly during the first few uses. The headaches typically occur within 1-2 hours of taking the medication and may last 2-4 hours.
If you experience a headache after taking sildenafil 50mg, paracetamol (up to 1000mg) or ibuprofen (200-400mg) can provide effective relief. These pain relievers are safe to use alongside sildenafil and won't interfere with its effectiveness for treating erectile dysfunction. Ensure you stay well-hydrated by drinking plenty of water, as dehydration can worsen headaches.
Many men find that headaches become less frequent or disappear entirely after using sildenafil several times as their body adjusts. Starting with adequate hydration before taking your dose may help prevent headaches. If headaches persist or become severe, your prescriber might recommend adjusting your dose to 25mg or trying the treatment at different times.
Whilst mild headaches are common, you should contact your healthcare provider if you experience severe headaches, sudden vision changes, or headaches that worsen over time. These could indicate rare but serious side effects requiring immediate attention.
