Miconazole (oral gel)

my-kon-ah-zole

What does it do?

Miconazole is used to treat fungal infections (thrush) in the mouth and throat and sometimes for other conditions.

How should you take it?

Take miconazole regularly as directed. Using the spoon provided, measure the dose carefully and place into your mouth near the affected area. Keep the dose in your mouth for as long as possible, before swallowing.
Do not eat or drink for 30 minutes after each dose. This will stop the medicine being washed away too quickly.
Keep taking it until the course is finished or for 7 days after your symptoms have stopped.

What if you forget a dose?

If it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take the missed dose as soon as you remember. Do not take two doses at the same time.

Can you take other medicines?

Some medicines available without a prescription may react with miconazole including:

  • sildenafil (e.g. Viagra®) or similar medicines

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
