Eye, ear, and nasal drops are topical dosage forms that are used to treat conditions affecting the eyes, ears, and nasal passages. Eye drops are used to treat conditions such as dry eyes, redness, and eye infections. Ear drops are used to treat ear infections, swimmer's ears, and other types of ear irritation. Nasal drops are used to treat nasal congestion, allergies, and other types of nasal irritation. These types of topical medications are formulated with active ingredients that are effective against the specific condition being treated. They are easy to use and convenient, but it is important to follow the manufacturer's instructions for use and to avoid touching the dropper tip to any surface to prevent contamination. Eye, ear, and nasal drops may cause side effects such as stinging, burning, or itching, so it is important to monitor for these and to discontinue use if necessary.
