Lisinopril Zestril, Dry Cough, Medication, T Claim, Stuffy Nose

Lisinopril was substituted for Zestril. No problems with Zestril, but with Lisinopril 30-45 min. after taking I always develop red, burning, itching arms and sometimes on other parts of body. This looks and feels like a very bad sunburn.
Also have annoying dry cough and stuffy nose.
Although bp somewhat under control, the side effects of this medication are unpleasant and most times unbearable.
What does this medication contain that causes these problems? If it's supposed to be the same as Zestril, then don't claim it is when it creates so many reactions. Insurance companies need to take their heads out of their wallets and gives patients quality care, not the cheapest they can find.
