Missed Doses

If you miss a dose of Diflucan, take it as soon as you remember. However, if it is close to the time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for the missed one.

Here are a few important points to keep in mind regarding missed doses of Diflucan:

  1. Timeliness: Try to take each dose of Diflucan at the same time every day. This will help maintain consistent levels of the medication in your body and maximize its effectiveness.
  2. Alarm or reminder: If you have difficulty remembering to take your medication, consider setting an alarm or using a reminder app to help you stay on track.

It is important to complete the full course of treatment with Diflucan, even if you miss a dose. Skipping doses or stopping treatment prematurely may result in incomplete eradication of the fungal infection and could increase the risk of recurrence.
