Yes! Make sure to rinse them out thoroughly between uses. If you are giving multiple medications, it's a good idea to stick with only one type per syringe. Each unique med should have its own syringe. This is not the case if you are using a standard syringe with a needle to inject the medication. In that case, each syringe will be a one-time-use item. Make sure to return the used syringes to the vet for proper disposal. Do not throw used needles in the garbage!!!
