jedno je sigurno.. alkohol i ketotifen ne idu zajedno.. Alkohol smanjiva ucinak antihistamini ( ketotifen )
Alcohol changes how medications, including antihistamines, become accessible to the human body. For example, if a person takes an antihistamine while drinking one to several alcoholic drinks over the course of four to five hours (acute drinking), the same metabolizing enzymes that process the antihistamine will attempt to metabolize the alcohol, as well. This exchange could reduce the progression of antihistamines being absorbed into the bloodstream, making the antihistamine less effective. On the other end of the spectrum, long-term drinkers may constantly activate the same enzymes used to metabolize antihistamines that also process alcohol. A chronic drinker, in this case, could develop a tolerance to antihistamines, and it would take more of the antihistamines to be effective.
