BNF-Listed Side Effects and Management Strategies
Common Side Effects (Affecting 1 in 10 users)
The British National Formulary identifies headache as the most frequent side effect of sildenafil, affecting approximately 15% of users. This typically occurs within 1-2 hours of taking the medication and resolves naturally as the drug leaves your system. Staying well-hydrated and using over-the-counter painkillers like paracetamol can help manage discomfort.
Flushing and nasal congestion are also common, caused by sildenafil's effect on blood vessels throughout the body. These effects are usually mild and temporary, lasting 2-4 hours. A cool environment and decongestant nasal sprays may provide relief if needed.
Digestive Side Effects Management
Dyspepsia (indigestion) and nausea affect some users, particularly when taking sildenafil with large or fatty meals. The BNF recommends taking sildenafil on an empty stomach or with a light meal to reduce digestive upset and improve absorption. If nausea occurs, avoiding alcohol and staying upright after taking the medication can help.
Visual and Hearing Effects
Some users experience temporary changes in colour vision or increased light sensitivity. These effects are generally mild and resolve within hours. However, sudden vision loss or hearing problems require immediate medical attention, as outlined in NHS emergency guidance.
When to Seek Medical Help
While serious side effects are uncommon, certain symptoms require urgent medical attention. Priapism (erection lasting over 4 hours) is a medical emergency that can cause permanent damage. Sudden chest pain, especially during sexual activity, may indicate cardiovascular complications and requires immediate assessment.
EverydayMeds offers both sildenafil (generic) and Viagra (branded) options, allowing you to choose based on your preferences and budget. Both formulations have identical side effect profiles, as they contain the same active ingredient in equivalent doses.
