Isoniazid and sleep aids: drug interactions
Isoniazid (INH) is an antibiotic used in the treatment of active Mycobacterium tuberculosis (TB) infection. It is also used to prevent TB in certain people at risk of infection. It is available as tablets (100 and 300 mg), syrup (50 mg/5 mL), or IV or IM injection (100 mg/mL).
Isoniazid interacts with many foods and medications. It is important to inform your doctor about all prescription and non-prescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take while on isoniazid. Your doctor may need to adjust the dosage or monitor you for side effects.
Isoniazid should not be taken with food as it reduces its bioavailability. It is recommended to take it on an empty stomach. Isoniazid prevents the breakdown of tyramine and histamine, leading to their buildup and causing side effects such as headaches, sweating, heart palpitations, flushing, and low blood pressure. Therefore, it is best to avoid foods and beverages containing high amounts of tyramine or histamine, such as certain cheeses, red wine, and some fish like tuna.
While there is no specific information about the interaction between sleep aids and isoniazid, it is crucial to consult your doctor or pharmacist before taking any sleep aids concurrently with isoniazid to ensure safety and avoid potential adverse reactions. They will be able to advise you on the specific sleep aid you are considering and provide guidance based on your individual circumstances.
