How to use Fungilin lozenges

Timing: Take Fungilin lozenges at about the same time each day, after meals and at bedtime. Suck the lozenge and allow it to dissolve slowly in your mouth. 
Dentures: If you wear dentures, take them out while sucking the lozenge. This allows the medicine to reach where the dentures normally fit. Before replacing your dentures, clean them thoroughly.
Teeth staining: Fungilin lozenges may cause yellowing of your teeth. If this happens, brushing your teeth will remove it.   
Missed dose: If you forget to take a dose, take it as soon as you remember, unless it is close to the time you would normally take your next dose. Do not take a double dose to make up for a forgotten dose.
