Seek immediate medical attention if you experience a prolonged erection (lasting more than 4 hours) or sudden vision loss. These are serious side effects requiring prompt medical intervention.
Common side effects include headache, flushing, nasal congestion, and upset stomach. These usually are mild and temporary. However, if they persist or worsen, consult your doctor.
Cardiovascular Considerations
Viagra can lower blood pressure. Individuals with pre-existing heart conditions, including uncontrolled high blood pressure, should discuss Viagra use with their physician before taking it. Avoid concurrent use with nitrates.
Other Precautions
Do not take Viagra if you have recently experienced a heart attack or stroke. Also, avoid its use if you have retinitis pigmentosa, a rare hereditary eye disease. Inform your doctor about all medications you currently take, including herbal remedies, to avoid potential drug interactions.
Viagra is intended for use by men only. It is not appropriate for women or children. Always follow your doctor’s prescribed dosage and instructions carefully.
