What do Major, Moderate and Minor mean?

Major

The combination can cause serious harm or stop a medicine from working. Usually avoided, or only used with close medical supervision.

Moderate

The combination may need care: a different dose, taking them at different times, or extra check-ups.

Minor

Little or no effect is expected. Usually nothing needs to change.

Duplicate

Two of your medicines contain the same ingredient, which can add up to a double dose.
