Common Side Effects and What to Expect
Mild Side Effects (Very Common)
The most frequently reported side effects of Viagra include headaches, facial flushing, and nasal congestion. These typically occur because sildenafil affects blood vessels throughout the body, not just in the genital area. Headaches affect up to 16% of users and usually resolve within 2-4 hours. Staying hydrated and taking paracetamol may help manage discomfort. Facial flushing appears as redness or warmth in the face and neck, affecting around 10% of users.
Digestive Side Effects
Indigestion and nausea occur in approximately 7% of users. Taking Viagra on an empty stomach or with a light meal may reduce digestive upset. Avoid fatty meals before taking the medication, as this can delay effectiveness and potentially worsen stomach discomfort. If persistent nausea occurs, consult your prescriber about dosage adjustment.
Visual and Sensory Changes
Some men experience temporary visual disturbances, including mild colour vision changes or increased light sensitivity. These effects are usually mild and resolve as the medication clears your system. However, sudden vision loss in one or both eyes requires immediate medical attention and discontinuation of the medication. Similarly, sudden hearing loss, though rare, needs prompt medical evaluation.
When to Seek Urgent Medical Help
Priapism (erection lasting over 4 hours) is a medical emergency requiring immediate treatment to prevent permanent damage. Chest pain, particularly during sexual activity, needs emergency medical attention. Severe allergic reactions, though extremely rare, may include difficulty breathing, swelling of face or throat, and require immediate emergency care.
Reducing Side Effect Risk
Starting with the lowest effective dose (typically 25mg or 50mg) helps minimise side effects whilst maintaining effectiveness. EverydayMeds offers both branded Viagra and cost-effective generic sildenafil in all available strengths. Avoiding alcohol and ensuring you're well-hydrated can reduce the likelihood of headaches and dizziness. Never exceed one dose in 24 hours, and allow adequate time between taking the medication and sexual activity.
