Yes i have and do occationally use human meds on my piggies. I am confident and happy to use them, as i am trained to work out dosages and understand the use/science of the medication. I am used to working out dosages etc and i have spoken to veterinary professionals about what i have used and they do not have a problem with it. I occationally use neurofen, Ibuprofen is safe at certain dosages and i am aware of the dosage. I would never advocate people to use human meds. Unless you understand the drug and its correct dosage its really not worth it.
Human medications can be dangerous and fatal to pets. For example half a 500mg Paracetamol can kill a cat, as would any type of penicillin based antibiotic with a guinea pig.
All of us in the veterinary profession are trained to prescribe medications for this reason. If you wish to give your piggie any of what you have listed please speak to a qualified vet or experienced veterinary nurse first. Unfortantly although a few human meds are useful to use on pets we very rarely advise people to use them, as 1.) we have probably not seen the animal, and 2.) many people (not suggesting yourself) are unable to dose their pets correctly with prescribed meds let alone ones not.
Hope this helps, and i hope it didnt sound like a rant.
