Potential Drug Interactions with Cialis

Always inform your doctor about all medications you are taking, including over-the-counter drugs, supplements, and herbal remedies, before starting Cialis. This includes nitrates, which can cause a dangerous drop in blood pressure when combined with Cialis. Avoid this combination.

Nitrates and Similar Medications

    Nitroglycerin (for angina) Isosorbide mononitrate (for angina) Isosorbide dinitrate (for angina)

Using Cialis with these medications can lead to severe hypotension (low blood pressure).

Alpha-Blockers

Alpha-blockers, often prescribed for high blood pressure or enlarged prostate, can increase the risk of low blood pressure when taken with Cialis. Your doctor may adjust your dosage or recommend an alternative.

Other Medications with Potential Interactions:

CYP3A4 inhibitors: These medications, such as ketoconazole and ritonavir, can increase Cialis levels in your blood, potentially leading to side effects. Your doctor might adjust your Cialis dosage. CYP3A4 inducers: Medications like rifampin can decrease Cialis levels, reducing its effectiveness. Dosage adjustments may be necessary. High blood pressure medications: Some blood pressure drugs can interact with Cialis, requiring careful monitoring and potential dosage adjustments.

Alcohol

Excessive alcohol consumption can worsen Cialis side effects, such as dizziness and headache. Moderate alcohol intake is generally acceptable, but you should discuss this with your doctor.

Grapefruit Juice

Grapefruit juice can interact with Cialis metabolism, increasing its levels in your blood. Limit or avoid grapefruit juice while taking Cialis.

Always consult your doctor or pharmacist if you have questions about potential drug interactions with Cialis. They can provide personalized guidance based on your specific health conditions and medications.
