I was prescribed nitrofurantoin 100 mg to take every 12 hours for five days. I am on the fifth day and have one dose left but it is clear this antibiotic is not working and my doctor has prescribed a new course of antibiotics for me( sulfamethoxazole- also 1 pill 12 hours apart for 5 days) I am assuming I should finish that last dose of the previous course of antibiotics before switching to the new one despite them not working, but do I start the new antibiotic 12 hours after my last dose of the previous course or should I wait for longer? I’m sorry if this is a stupid question it’s my first time dealing with being resistant to an antibiotic or having to start a new one so soon after the previous course.
I have been prescribed a new antibiotic whilst still taking one, when do I start it?

It sounds that the logical step would be to start the new antibiotic 12 hours later.
Just to be on the safe side call your Dr., if you can not confirm with him/her ask the nurse if not ask a Pharmacist.
