Sildenafil 20mg, while generally well-tolerated, can cause side effects. Common ones include headache, flushing, nasal congestion, and indigestion. These usually are mild and temporary. Less frequent side effects include visual disturbances (blurred vision, changes in color perception), dizziness, and back pain.
Serious Side Effects: Seek Immediate Medical Attention
Rare but serious side effects require immediate medical help. These include prolonged erection (priapism), sudden vision loss, and hearing loss. These conditions need prompt attention to prevent lasting damage.
Before taking Sildenafil 20mg, discuss your medical history with your doctor. This includes any heart conditions, low blood pressure, liver or kidney problems, retinal issues, or blood cell disorders. Also mention any other medications you take, particularly nitrates, as combining them with Sildenafil can be dangerous. Alcohol consumption can also increase side effects. Follow your doctor’s instructions carefully regarding dosage and frequency. Do not exceed the recommended dose. If you experience any concerning side effects, contact your doctor immediately.
