Ibuprofen allergy?

When I take Ibuprofen for my period (use it for around 3 days), I break out in a red blotchy rash under my breasts and around my navel.  I'm not sure if using a heating pad during this time also has something to do with it as I do not get this rash when taking ibuprofen for other ailments such as a one time use for a headache.

Hello,
This is not due to ibuprofen allergy as the reaction is localized and seems to be due to heat rashes/contact dermatitis due to hot water bottles.Had it been a drug allergy,it would have occurred at other times also.The next time during your periods,avoid using hot bottlesas you may be allergic to rubber/latex.If the same happens without using hot bottles,then allergies can be considered,otherwise not.
Hope it helps.Take care and pls do keep us posted on how you are doing.
