If they are oral, either with a plastic syringe that the doctor gives you or you can inject the meds into a feeder(with a needle syringe) like a hornworm or silkworm. You would just have to pry the mouth open and squirt the meds in if you opt not to inject the feeder. And then there are antibiotic injections, which I would not want to do or have never had to thank god!
