Cialis can interact with other medications. This is particularly true for nitrates (used to treat chest pain) and alpha-blockers (used to treat high blood pressure or enlarged prostate). Combining these can cause a dangerous drop in blood pressure. Inform your doctor about all medications, including herbal remedies, you are taking.
Medication Interactions:
Nitrates: Avoid taking Cialis with nitrates. Alpha-blockers: Your doctor may need to adjust your dosage. Other medications: Discuss all medications with your doctor before starting Cialis.
Grapefruit juice can also affect how Cialis works in your body; avoid excessive consumption while taking this medication.
