ALLERGIES, bee sting, Sulfa drugs: there's another caution about Lisinopril I just discovered. Not only is this drug not to be used with people who have history of dehydration, it is contraindicated with people with allergies such as bee stings and SULFA drugs. Do not take your med provider or pharmacist word, find out for yourself before swallowing something that could be POISON to you! God bless and good luck to all of you.
