Acetylcysteine is contraindicated in those patients who are sensitive to it. Acetylcysteine should be given in caution in asthma patients.
Taking other medicines
After taking Acetylcysteine orally it increases the bioavailability of amoxicillin, but shows no effect on doxycycline and reduces the absorption of cefalexine. Acetylcysteine seems to increase the effects of nitroglycerin. Taking Acetylcysteine at the same time as activated charcoal might decrease how well it works for preventing poisoning.
