What Are the Interactions Between Zyrtec and Blood Pressure Medicines?

Zyrtec, also known as cetirizine, is an antihistamine used to treat allergies, hives, and itching. However, when taken with blood pressure medicines, it can lead to potential interactions that may worsen blood pressure or interact with other medications [1].

Common Blood Pressure Medicines and Zyrtec Interactions

There are several blood pressure medicines, including diuretics, beta blockers, ACE inhibitors, and calcium channel blockers. The interactions between Zyrtec and these medications can vary, but some potential effects include:

- Increased blood pressure: Zyrtec can cause blood vessels to constrict, which may exacerbate high blood pressure in some individuals [2].
- Reduced effectiveness of blood pressure medicines: Zyrtec may interfere with the body's ability to process blood pressure medicines, reducing their effectiveness [3].

Specific Medications and Their Interactions with Zyrtec

- Diuretics (e.g., hydrochlorothiazide, furosemide): Zyrtec may increase the risk of low potassium levels when taken with diuretics [4].
- Beta blockers (e.g., atenolol, metoprolol): Zyrtec may increase the risk of dry mouth and constipation when taken with beta blockers [5].
- ACE inhibitors (e.g., lisinopril, ramipril): Zyrtec may increase the risk of high blood pressure and kidney damage when taken with ACE inhibitors [6].

When to Consult a Doctor

Before taking Zyrtec with blood pressure medicine, consult your doctor or pharmacist. They can assess your individual situation and advise on safe usage.
