How a pharmacist can help
Oral thrush can be easily treated with a mouth gel bought from a pharmacy. Treatment usually lasts at least 7 days.
Ask your pharmacist for advice. Always follow the instructions on the medicine packet.
If you leave oral thrush untreated, the infection can spread to other parts of the body.

See a GP if:
