Blood pressure meds, tinnitus linked

Dear Dr. Roach: I recently spent time with a seasoned hearing-impaired citizen. She told me that tinnitus is sometimes caused by prescription meds, especially those for high blood pressure. I have been taking 25 milligrams of losartan, one per day in the morning for about 15 years. About five years ago, my tinnitus began. Lately, it seems to have become worse. Do you think there is a connection?

F.A.C.

Answer:

There is a long list of medicines that can cause tinnitus. I have done some research suggesting that angiotensin receptor blockers like losartan have a lower risk of tinnitus compared with other blood pressure drugs. I don’t think changing medicines from losartan is likely to help your tinnitus, and you should never stop a medicine without discussing with your doctor.

I should note that pulsatile tinnitus — when the sound one hears is not a constant tone, but rather a sound that pulses in time with the heartbeat — is sometimes associated with an aneurysm. This should have an evaluation.

Dear Dr. Roach: You wrote in a recent column that N95 masks should be reserved for health care workers and asked that people donate any unused masks to hospitals. My question concerns N95 masks with exhalation valves.

I understood that those should not be donated because the exhaled air is not filtered and therefore does not prevent an infected wearer from spreading COVID. Can you clarify?

Answer: According to the Centers for Disease Control and Prevention, N95 respirators with an exhalation valve do not provide the same protection to the wearer as those without, and provide little or no protection to the people around the wearer. If the only respirator you have contains a valve, it is recommended that you wear a surgical mask on top of the respirator.
