Understanding Sildenafil Side Effects: What to Expect
Common Side Effects (Affect 1 in 10 or more users)
The most frequently reported side effects of sildenafil include headache, facial flushing, indigestion, and nasal congestion. These effects typically occur because sildenafil affects blood vessels throughout the body, not just in the penis. Most users find these side effects mild and manageable, usually subsiding within 2-4 hours as the medication clears from the system.
Uncommon but Notable Side Effects
Some users may experience dizziness, visual disturbances (such as colour tinge or increased light sensitivity), or muscle aches. These effects are generally temporary but may be more noticeable when first starting treatment. If visual changes persist beyond a few hours, seek medical advice promptly.
Serious Side Effects Requiring Immediate Medical Attention
Whilst rare, certain side effects require urgent medical care. These include prolonged erection lasting more than 4 hours (priapism), sudden vision loss, sudden hearing loss, or severe chest pain during sexual activity. Priapism affects fewer than 1 in 1,000 users but requires emergency treatment to prevent permanent damage.
Managing Side Effects Effectively
Taking sildenafil on an empty stomach may reduce the likelihood of indigestion. Staying hydrated can help minimise headaches, whilst avoiding alcohol may reduce dizziness and flushing. If side effects persist or worsen, consult your prescriber about adjusting your dose. EverydayMeds offers both generic sildenafil and branded Viagra, with dosage options of 25mg, 50mg, and 100mg to help optimise your treatment.
When to Contact Your Healthcare Provider
Contact your prescriber if you experience unusual or severe side effects, if common side effects don't improve after several uses, or if you develop new symptoms whilst taking sildenafil. Our UK-licensed clinical team at EverydayMeds provides ongoing support for all patients, ensuring safe and effective ED treatment.
