Otex ear drops are used to help remove hardened wax from the ear canal. • Otex is suitable for use by adults, children and the elderly. • The active ingredient is urea hydrogen peroxide. It works by breaking down the ear wax into small pieces. • Excessive, hardened ear wax is quite common. It causes problems when it builds up and blocks the ear canal. The first symptom is usually a feeling of discomfort and fullness in the ear. This can become painful and cause dizziness and some loss of hearing if left untreated. • Otex makes removal of ear wax easier, and in many cases avoids the need for ear syringing.
