Always inform your doctor about all medications you’re taking, including over-the-counter drugs, supplements, and herbal remedies. This includes nitrates (used for chest pain), alpha-blockers (used for high blood pressure or enlarged prostate), and certain antifungal medications. These can interact dangerously with Cialis.
Specific interactions include:
- Nitrates: Combining Cialis with nitrates can cause a significant drop in blood pressure, potentially leading to dizziness, fainting, or even a heart attack. Avoid using them together. Alpha-blockers: Concurrent use can result in a marked decrease in blood pressure. Your doctor may adjust your dosage of either medication or suggest alternatives. Azole antifungals (e. g., ketoconazole, itraconazole): These can increase Cialis levels in your blood, potentially intensifying side effects. Your doctor might lower your Cialis dosage. HIV protease inhibitors (e. g., ritonavir, indinavir): Similar to azoles, these can raise Cialis blood levels, requiring potential dosage adjustments. Grapefruit juice: Grapefruit juice inhibits enzymes that metabolize Cialis, leading to elevated blood levels and increased risk of side effects. Avoid consuming it while taking Cialis.
Alcohol can enhance Cialis’s side effects, particularly dizziness and lightheadedness. Moderate alcohol consumption is advised.
This list isn’t exhaustive; other medications may interact. Discuss any concerns with your healthcare provider before taking Cialis, especially if you have pre-existing health conditions or are taking other medications.
Always consult your doctor before starting or stopping any medication. Provide a complete list of your medications and supplements to your doctor. Never self-medicate or alter prescribed dosages without medical supervision.
