Hydrocortisone Buccal Tablets

What are hydrocortisone buccal tablets?

Hydrocortisone buccal tablets are a type of steroid medicine used to treat inflammation in the mouth. They are designed to dissolve slowly when placed against the affected site such as inside of the cheek (buccal area) or against an ulcer, allowing the medicine to act directly on the affected area. The most common brand name in the UK is Corlan. They can either be prescribed by your doctor or bought in pharmacies, however, due to a supply issue, they are not currently available. If you have been prescribed this medication, speak to your doctor for an alternative[1].
