92 yr old woman has upper respiratory infection. Just want to make sure its OK to mix bactrim with her other medication. She has Altimers, but besides that is in great health.

This is something I would be asking your doctor or pharmacist. They've got a better idea of drug interactions.

Altimers? Do you mean Alzheimer's?

Yes, I agree with Craven, this is something better discussed with her pharmacist/chemist.
