A dry, persistent, tickly cough is a recognised, common ( ie 1 in 100) or so side effect of a class of drugs known as ACE inhibitors, of which Ramipril is probably the best known.Much work has been done to identify what is going on, and it appears that the action of ACE inhibitors allows for an accumulation of substances that would otherwise be metabolised, and stimulate nerve fibres. If the cough is sufficiently persistent, frequent or irritating enough to effect your or your families quality of life, then it is definitely worth discussing a possible change of medication with your GP.
There are other classes of drug, such as angiotensin -II receptor agonists ( Angiotensin Receptor Blockers, or ARB) that your GP might feel is appopriate for your condition.
