Carprofen is an nonsteroidal antiinflammatory medication (NSAID) like aspirin or ibuprofen for humans. It's used daily for arthritis or other chronic pain, and short term for more acute/temporary pain. The half life is the amount of time it takes for half of the drug to leave the body (via the liver, kidneys/bladder, or gut). Carprofen can occasionally have side effects on the liver, so if he's going to be on it long term, it's usually recommended to check liver values after 2 weeks. That said, liver issues are rare. Intestinal upset (vomiting/diarrhea) are also possible side effects and if he had any of that you'd want to stop and figure out a different appropriate medication with his vet. With just 6 days of medication, no additional testing will be done. You can (and should, if that is how it was prescribed) give carporfen daily. Appropriate supplements could include fish oils and glucosamine and others, depending on what exactly is going on. I'd recommend asking about supplements for long term when you go for your recheck visit
