Always follow the instructions from a pharmacist or doctor, or the leaflet in the medicine packet.
Dosage
Each hydrocortisone buccal tablet contains 2.5mg of hydrocortisone.
It's usual to use 4 tablets a day for up to 5 days. Try to leave a gap of 3 to 4 hours between tablets.
If the ulcer heals in less than 5 days, you can stop using the tablets.
See your doctor if the ulcer has not healed after 5 days, or if it heals but comes back again.
How to use buccal tablets
Put the buccal tablet in your mouth against the ulcer and let it dissolve there.
Do not chew or swallow the tablet. If you do this, the tablet will not work and you may get side effects.
If you have more than 1 mouth ulcer, move the tablet around your mouth, sharing it between each ulcer. Do not use more than 1 tablet at a time and do not use more than 4 in a day.
If you forget to use it
If you forget a tablet, use it as soon as you remember, unless it's less than an hour until the next one is due. In this case, skip the missed tablet and use your next one at the usual time.
Never use 2 doses at the same time. Never have an extra dose to make up for a forgotten one.
If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicines.
If you use too many
Buccal tablets contain a very low dose of hydrocortisone. Using too many is unlikely to harm you. Talk to a pharmacist if you're worried.
