To treat my diabetes, I started taking tradgenta two months ago, in addition to glimiperide and metformin.  I have had no reaction it, until possibly now.  The results have been excellent in controlling mt blood sugar.  I have been golfing the last two days in hot humid weather and I have itchy skin with a rash  at the waistline and bra lines when I finish golfing where my clothing contacts my skin.  My clothes are not too tight.  The rash goes away by morning.    I really would hate to stop my tradgenta....it is working so well.  Can Medicines cause a rash after being tolerated well for two months?  Are there other meds in that class that might be a good alternative or are they likely to cause a rash, also?   I put on some hydrocortisone cream to help relieve the itching. Any other ideas?  This sequence has been going on for 2 days.Thank you very much.Martha
Howell come to ChatDoctorI really appreciate your concern, of course the antidiabetes medicines could cause the hypersensitivity reaction but in your case chances of this is very less like, but it seems to be sun sensitivity, stop going in the sun if the symptoms appears even after that then it may be something else but not the sun, I would advise you to keep taking the anti-diabetic Chat Doctor.
