which 1st Antihistamines have least/no anticholinergic effects?
Im in the U.K Diphenhydramine, Promethazine are both OTC Antihistamines i usually use when using Opiates like Oxy, DHC, Codeine, Poppy Pod Tea etc
But ive read a warning that using anticholinergic antihistamines alongside Morphine can pose some problems.
How serious should this warning be taken? Because i dont want to be itching like futhermucker!
