Always follow your doctor’s instructions precisely. The typical starting dose is 50mg, taken about an hour before sexual activity. Your doctor might adjust this based on your response and health condition. Never exceed the maximum recommended dose of 100mg in a 24-hour period.
Common Side Effects and Precautions
Viagra can cause headaches, facial flushing, and nasal congestion. More serious side effects, though rare, include vision changes and prolonged erection (priapism). Seek immediate medical attention if you experience a prolonged erection lasting more than four hours. Avoid Viagra if you have heart problems, uncontrolled high or low blood pressure, or certain eye conditions. Grapefruit juice can interact with Viagra, increasing its effects, so avoid it.
Interactions and Contraindications
Inform your doctor about all medications you’re taking, including over-the-counter drugs and supplements. Some medications can interact negatively with Viagra. This includes nitrates, commonly prescribed for chest pain. Viagra is not suitable for women or individuals under 18 years of age.
