Always inform your doctor about all medications you are taking, including over-the-counter drugs, herbal supplements, and recreational drugs. This includes nitrates, often found in medications for chest pain (angina). Combining Levitra with nitrates can cause a dangerous drop in blood pressure.
Specific Medication Interactions
Levitra’s interaction with certain medications is well-documented. Alpha-blockers, used to treat high blood pressure and enlarged prostate, can potentiate Levitra’s blood pressure-lowering effects. Similarly, interacting with protease inhibitors (HIV medications) can increase Levitra’s concentration in your bloodstream, potentially causing side effects. Always discuss potential interactions with your doctor before combining Levitra with other drugs, particularly those affecting blood pressure or liver function.
Alcohol and Grapefruit Juice
Excessive alcohol consumption can worsen Levitra’s side effects, notably dizziness and lightheadedness. Grapefruit juice inhibits enzymes that metabolize Levitra, leading to higher blood concentrations and increased risk of side effects. Avoid grapefruit juice while taking Levitra.
Other Substances
Before using Levitra, disclose any use of recreational drugs or illegal substances to your doctor. These substances can interact unpredictably with Levitra, increasing risks.
