Always inform your doctor about all medications you are taking, including over-the-counter drugs, herbal supplements, and recreational drugs, before starting Viagra. Certain combinations can be dangerous.
Nitrates and Nitroglycerin
Combining Viagra with nitrates, such as nitroglycerin used for chest pain (angina), can cause a dangerously low blood pressure. This interaction can lead to severe dizziness, fainting, or even a heart attack. Never take Viagra if you are using nitrates.
Alpha-blockers
Alpha-blockers, often prescribed for high blood pressure or enlarged prostate, can also lower blood pressure. Taking Viagra with alpha-blockers may increase the risk of low blood pressure, particularly when starting treatment or increasing the dose of either medication. Your doctor should carefully monitor your blood pressure if you use both.
Other Medications
Viagra can interact with various other medications, including antifungal drugs (like ketoconazole), HIV protease inhibitors, and certain antibiotics. These interactions can either enhance or diminish Viagra’s effects, potentially leading to side effects or reduced efficacy. Always discuss potential interactions with your physician.
Alcohol and Grapefruit Juice
Excessive alcohol consumption can worsen Viagra’s side effects, such as headaches and dizziness. Similarly, grapefruit juice can inhibit the metabolism of Viagra, leading to increased blood levels and a heightened risk of side effects. Moderate alcohol consumption and avoidance of grapefruit juice are recommended.
Recreational Drugs
The combination of Viagra with recreational drugs, especially those affecting the cardiovascular system, can be extremely risky. This combination may significantly increase the risk of heart problems and other serious side effects. Avoid using Viagra with recreational drugs.
