I also have a long history of allergies in my life (rhinitis, latex, dog
and cat hair, contact
and atopic dermatitis)
and my grandmother was allergic to basically 90% of all drugs.
A couple of weeks weeks ago, I was feeling unwell, so I took 600mg of ibuprofen and something for the fever (I don't really remember what it was) twice a day for a week and then went to the doctor because I was not getting better.
