Always talk to your doctor before starting Viagra. Some men experience mild side effects. These commonly include headache, facial flushing, nasal congestion, and indigestion. These usually subside on their own. However, more serious, though rare, side effects exist.
Serious Side Effects
Seek immediate medical attention if you experience prolonged or painful erection (priapism), sudden vision loss, or hearing loss. These can be signs of a serious medical problem. Also, report chest pain, irregular heartbeat, or stroke-like symptoms such as weakness or numbness in your limbs.
Precautions
Heart conditions: Viagra can increase the strain on your heart. If you have heart disease, high blood pressure, or have recently had a heart attack or stroke, carefully discuss Viagra use with your physician. Blood pressure medications: Interaction with certain blood pressure drugs is possible. Consult your doctor about potential interactions. Nitrate medications: Never take Viagra if you are using nitrates for chest pain. This combination can be dangerous. Liver or kidney disease: If you have liver or kidney problems, your doctor may adjust your Viagra dosage or recommend an alternative.
Medication Interactions
Many medications can interact with Viagra. Provide your doctor with a complete list of all medications, including over-the-counter drugs and supplements, you are currently taking. This helps prevent potential adverse interactions.
Alcohol Consumption
While moderate alcohol consumption is generally acceptable, excessive alcohol use can increase the risk of side effects. Limit your alcohol intake while taking Viagra.
