Journal database symptoms and conditions

have been on Lisinopril/HCTZ for over a year with no side effects. Last week I switched to Cartia XL because I am 29 and wanted to try to have a baby. The Cartia made me severely depressed so after four days I switched back to my Lisinopril/HCTZ until my follow-up appt. in three weeks. I took the Lisinopril/ HCTZ for two days. The first day I had a weezy cough. The second day I broke out in a rash that was unaffected by benadryl. I looked in OVID medical journal database and found that the symptoms of Lisinopril rash are rashes confined to the trunk, neck, and proximal limbs (closest to body) and are unaffected by Benadryl (because the rash is caused by luekotriene and not histamine reaction). I went to urgent care today and they gave me a benadryl shot and three prednisone pills with no effect. Then they gave me a IV drip with Zantac (the heartburn medicine but also can help with rashes). It helped some but I am back at home and the rash looks worse and still itches. This is horrible.
