Understanding Viagra Dosage and Side Effects

Always consult your doctor before starting Viagra. The standard starting dose is 50mg, taken about one hour before sexual activity. Your doctor may adjust this based on your response and health conditions. Never exceed 100mg in a 24-hour period.

Common side effects include headache, facial flushing, nasal congestion, and indigestion. These are usually mild and temporary. However, serious side effects, though rare, exist.

Viagra can interact with other medications, particularly nitrates. Inform your doctor about all medications you are taking, including over-the-counter drugs and supplements. Conditions like heart disease, low blood pressure, or liver/kidney problems may influence dosage and safety. If you experience any concerning side effects, contact your doctor or seek medical help without delay.
