Essential Safety Guidelines and Troubleshooting
Understanding MHRA-Approved Sildenafil Treatment
The MHRA regulates sildenafil as a prescription-only medicine, ensuring patient safety through strict clinical protocols. Both Viagra and generic sildenafil contain the same active ingredient - sildenafil citrate - working as PDE5 inhibitors to increase blood flow when sexually stimulated. EverydayMeds offers both options, allowing patients to choose between branded or generic alternatives following successful consultation.
Clinical Assessment Requirements
UK regulations require comprehensive medical evaluation before prescribing sildenafil. Our clinical assessment evaluates cardiovascular health, current medications, and medical history. This process identifies potential contraindications and ensures safe treatment. Adult men aged 18+ with erectile dysfunction may be eligible following successful assessment by UK-licensed prescribers.
Critical Safety Contraindications
Certain conditions absolutely contraindicate sildenafil use. Never take sildenafil if using nitrates (GTN spray, isosorbide), riociguat, or experiencing severe heart disease. Recent heart attack or stroke within six months, severe liver impairment, very low blood pressure, or hereditary retinal disorders also preclude treatment. Always disclose complete medical history during consultation.
Dosage and Administration Guidelines
Standard starting dose is 50mg, taken 30-60 minutes before sexual activity. Dosage may be adjusted to 25mg or 100mg based on effectiveness and tolerability. Maximum frequency is once per 24 hours. Fatty meals can delay onset, so consider timing with food intake. Effects typically last 4-6 hours, though this doesn't mean continuous erection.
Troubleshooting Common Issues
If sildenafil appears ineffective, consider timing, food intake, and realistic expectations. Sexual stimulation remains necessary - sildenafil doesn't cause automatic erections. Stress, alcohol, and underlying health conditions can impact effectiveness. Persistent issues warrant consultation review. Side effects like headaches, flushing, or indigestion are common and usually mild. Seek immediate medical attention for prolonged erections exceeding four hours or sudden vision changes.
