Short answer: The Invokana label says to take a missed dose as soon as possible and not to double the next dose. The Medication Guide adds: if it is almost time for your next dose, skip the missed dose and take the next at the regular time. Invokana is normally taken once daily before the first meal of the day.
| Situation | What the label says |
|---|---|
| Schedule | Once daily, before the first meal of the day (2.2) |
| Missed a dose | Take it as soon as possible (2.6) |
| Almost time for the next dose | Skip the missed dose (Medication Guide) |
| Doubling up | Do not double the next dose (2.6) |
| Several days missed | No specific rule in the label |
Section 2.6 says that if a dose is missed, take it as soon as possible, and do not double up the next dose. The Medication Guide says to skip the missed dose if it is almost time for the next one, and never to take two doses at the same time.
Example: you take Invokana before breakfast and notice at 2 p.m. that you forgot. Under the label you would take it at 2 p.m. The label does not require it to be with a meal when taken late; ask your pharmacist if you are unsure.
Section 2.2 gives the starting dose as 100 mg once daily, taken before the first meal of the day, to improve blood sugar control. That timing is about how the dose works with your largest meals, not a hard cutoff for a missed dose.
The Invokana label does not say what to do after several missed days. That is a question for your prescriber.
