Propranolol is named in the leaflet as a medicine that interacts with the rifampicin, isoniazid, pyrazinamide and ethambutol combination. The text does not say what the effect is, only that the two interact, so ask your doctor or pharmacist before taking them together.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
