Is it safe to take Telmisartan and Diltiazem together?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

My father recently underwent surgery on his right leg, specifically a proximal femoral nail (PFN) procedure. After the operation, an echocardiogram was performed, which showed a pressure of 75 mmHg and a dilated right atrium and right ventricle (RA-RV). The doctor prescribed the following medications: Diltiazem twice a day, a combination of Furosemide and Spironolactone (half a tablet in the morning), and Apixaban 5 mg twice a day.

This month, another echocardiogram was done, which showed a pressure of 40 mmHg and a normal RA-RV. We consulted the doctor again, and he adjusted the medications to Diltiazem twice a day, Apixaban 5 mg twice a day, and Telmisartan 40 mg at night.

Is it safe to take both Telmisartan and Diltiazem together, as they both lower blood pressure? His current BP is 126/80. Before the surgery, my father was taking Telmisartan and Amlodipine regularly.

Please suggest.

Hello,

Welcome to icliniq.com.

Based on the description of your father's echocardiogram findings over the past two months, it seems that he experienced a blood clot in the pulmonary arteries following his leg surgery. The good news is that the treatment was appropriate, and he has responded well, as his RA-RV is now normal, and the pressures have decreased to 40 mmHg.

I would suggest considering Diltiazem once daily, given that he is also taking Telmisartan. You should consult your doctor and share your concerns. Make sure to keep him active and encourage moderate exercise.

I hope this helps.

Thank you.

Hello doctor,

Thank you for the reply.

If he takes Diltiazem twice a day without taking Telmisartan at night, is that okay?

Hello,

Welcome back to icliniq.com.

You can give him Diltiazem and monitor his blood pressure. If it remains above 140 mmHg, I suggest adding Telmisartan.

I hope this helps.

Thank you.
