I just suffered a fairly serious bout of anaphalaxis due to an antibiotic my Dr. prescribed last Thursday. The pharmacist advised that there was a small chance I may have a reaction, I am allergic to shellfish and nuts, among other things. I took the first dose after dinner Friday, and two more Saturday, another one Sunday morning. By late afternoon Sunday it was clear that I was beginning to have a reaction, and it progressed through the day and into the evening. I stopped the medication and started antihistamines to counter the reaction. Finally by late this afternoon I feel fine again.
