I feel like I might have mixed up the discard times for different antibiotics. I need to double-check if cephalexin is 7 or 14 days.

I remember practicing a question like this, and I think the correct answer was to discard after 14 days. Protecting from light seems less relevant for this one.

I think cephalexin needs to be refrigerated after reconstitution, but I'm not sure about the discard time. Was it 7 or 14 days?

I feel pretty confident about this one. Liquid oral suspensions generally need to be protected from light and have a shorter expiration date compared to solid dosage forms. So the best answer is option B - protect from light and discard after 14 days.

Okay, let's see. Cephalexin is an antibiotic, so it makes sense that it would need to be kept refrigerated to maintain potency. And a liquid formulation would probably have a shorter shelf life than tablets or capsules. I'm going to go with option C.

Option A sounds like the way to go. Protect it from light, and 7 days is just the right amount of time before it turns into a science experiment.

Haha, I bet the answer is D. Who doesn't love some extra fridge time and a longer shelf life? Cephalexin must be a hardy little antibiotic.
