Always inform your doctor about all medications you’re taking, including over-the-counter drugs, herbal supplements, and recreational drugs. This includes nitrates (found in some heart medications), alpha-blockers (used for high blood pressure or enlarged prostate), and antifungal medications like ketoconazole or itraconazole. Combining Cialis with these can significantly lower blood pressure, potentially causing dizziness or fainting.
Grapefruit juice inhibits the enzymes that metabolize Cialis, leading to increased blood levels and a higher risk of side effects. Avoid grapefruit juice while taking Cialis.
Alcohol can intensify Cialis’s side effects, such as headaches and dizziness. Limit alcohol consumption while using Cialis.
Certain medications used to treat HIV/AIDS can interact with Cialis, potentially affecting its effectiveness or increasing side effects. Discuss this with your doctor if you’re taking these medications.
| Nitrates | Severe drop in blood pressure | Avoid concurrent use. |
| Alpha-blockers | Increased risk of low blood pressure | Consult your doctor before combining. |
| Azole antifungals (ketoconazole, itraconazole) | Increased Cialis blood levels | Use caution and consider lower Cialis dosage. |
| HIV/AIDS medications (ritonavir, indinavir) | Altered Cialis metabolism | Discuss with your doctor; dosage adjustment may be needed. |
