After opening, Mometamax ear drops are generally considered effective for up to 7 days, but you should always follow your veterinarian’s instructions. Do not use the medication past the expiration date printed on the bottle, and discard any unused product if your vet advises. If you have concerns about the medication’s safety or effectiveness, consult your veterinarian.
