It took about 2 months for the cough to kick in for me, but MAN, it was brutal. Sometimes I would cough so bad tears would be running down my face. I asked my EX-dr. to please get me off these things, but she wouldn't, said "they are a great drug" and I would get over the cough.
She kept me on those things for almost 2 years, yes, the cough finally went away after about 5 months, but I had other lousy affects from Altace (Ace drug) and to be honest, it did nothing for my BP. I now have a new dr. and am on Atenolol, not crazy about it, but it seems better then Altace. I know a few people who swear by it, so maybe he will get use to it and have no other problems. Good luck!!
