This prescription-only ear spray contains dexamethasone (a steroid), neomycin (an antibiotic) and acetic acid. It treats inflammation and infection of the outer ear canal (otitis externa, sometimes called swimmer's ear). The Otomize brand has been discontinued in the UK; this is the generic version with the same three ingredients. At Ways Pharmacy it is supplied only after a pharmacist has assessed your symptoms and confirmed that it is suitable for you.
How to access this medicine
- Start your free online assessment. Complete a short questionnaire and confirm your identity by uploading photo ID or showing it on a video call.
- Pharmacist reviews and speaks with you. A GPhC-registered pharmacist contacts you by phone or video to go through your answers and confirm whether this medicine is suitable. If you are under 18, a parent or guardian must join the video call. If the pharmacist needs to look inside your ear — for example to rule out a perforated eardrum or a middle ear infection — they will ask you to visit our Holborn pharmacy for a free ear examination before supplying.
- If suitable, order and pay on this page. Once the pharmacist confirms the medicine is suitable, you add the medicine to your basket and check out on this page, or call 020 8106 7084. If it is not suitable — including when the pharmacist gives advice only — you pay nothing and the pharmacist explains your other options. If you have already paid and the pharmacist finds the medicine is not suitable, you receive a full refund.
- We post your medicine or you collect it. Once approved, orders placed by 3pm on a weekday are posted the same day (see our shipping policy), or you can collect from Holborn.
There is no separate consultation fee. If the medicine you chose is not suitable, the pharmacist may suggest another option.
