Drugs that cause tinnitus include water pills, such as ethacrynic acid, bumetanide and furosemide; cancer medications, such as vincristine and mechlorethamine; and antibiotics, such as erythromycin, neomycin and polymyxin B, states Mayo Clinic. Quinine medications, certain antidepressants and high-dose aspirin can also cause this condition.
Tinnitus or ringing in the ears, is a symptom of conditions such as a circulatory system disorder or ear injury and worsens with age, reports Mayo Clinic. The effects of drugs that can cause tinnitus depend on the dose, and this condition can improve after the patient stops using the drugs. Patients should consult their doctors if tinnitus occurs after taking a medicine, advises WebMD.
