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.
The most frequently reported side effects of Viagra include headaches (affecting up to 16% of users), facial flushing, and mild nasal congestion. These effects typically occur because sildenafil affects blood vessels throughout your body, not just in the genital area. Headaches can often be managed with paracetamol, though you should avoid exceeding recommended doses. Staying well-hydrated before taking Viagra may help reduce headache intensity.
Indigestion and stomach upset affect approximately 7% of men taking Viagra. Taking the medication on an empty stomach can reduce nausea but may also speed absorption. If you experience persistent stomach issues, consider taking Viagra with a light, low-fat meal. Facial flushing usually subsides within 2-3 hours and can be minimised by avoiding alcohol and staying in cooler environments.
Whilst rare, some side effects require urgent medical care. Priapism - an erection lasting more than 4 hours - occurs in less than 1% of users but constitutes a medical emergency. Contact emergency services immediately if this occurs, as delayed treatment can cause permanent damage. Never attempt to manage prolonged erections yourself.
Sudden vision changes, including partial vision loss or blue-tinted vision, affect fewer than 2% of users but require prompt medical assessment. Similarly, sudden hearing loss or ringing in ears (tinnitus) warrants immediate medical attention. These effects may indicate rare but serious complications requiring professional evaluation.
Viagra's most dangerous interactions occur with nitrate medications commonly prescribed for chest pain. This combination can cause severe blood pressure drops requiring emergency treatment. Always inform healthcare providers about Viagra use before receiving any new medications. Blood pressure medications may also interact with sildenafil, potentially causing dizziness or fainting.
EverydayMeds offers both branded Viagra and generic sildenafil with identical active ingredients and side effect profiles. Some patients prefer branded Viagra for consistency, whilst others choose generic sildenafil for cost-effectiveness. Both options undergo the same rigorous safety monitoring and clinical oversight through our UK-licensed prescriber network.
If side effects persist or worsen over several doses, consider dose adjustment through clinical consultation. Starting with 25mg may reduce side effect intensity whilst maintaining effectiveness. Conversely, men experiencing minimal effects might benefit from 50mg or 100mg dosing after clinical review. Never adjust doses without professional guidance, as this affects both safety and treatment success rates.
