Cautions

If there is a possibility that you already have an ear infection, or your ear drum has ever been perforated, or otherwise injured, or if you have ever had ear surgery, it is important to consult an ear doctor (ENT, or ear, nose and throat specialist) before you use any type of ear drops (or before swimming).[2]
