ModerateThere is one reported case of an interaction involving alcohol and a medicine that combines pyrimethamine with dapsone. There is also a separate reported case in which salbutamol strengthened the effect of betahistine.
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.
