Sulfamethoxazole and mistakes

I'm posting this for nikieis, who's husband has been having problems with the Sulfameth. The Doctor and the Walgreens Pharmacist that you spoke to made a mistake, rare side effects of Sulfameth are cold sores, persistent sore throat and fever. I'm surprised that the Walgreens Pharmacist made such a mistake because they usually are so efficient, and if a patient complains about a symptom they will look up in their computer to see the possible side effects - both common and rare. If you still have the Walgreens pick-up slip, it will have a drawing of the drug as well as a description so that there are no possible mistakes. Also, on the pick-up slip is a list which describes the drug, what its for, how to use the medicine, cautions, possible side effect, rare side effect and effect to contact you Doctor immediately for. I would also think that if the information is on the packing slip, that the Walgreens website would have all the possible side effects and cautions. so Patients can look them up if they want to be informed about the medication.
I hope that your husband has recovered and is feeling better.
