Defaz CI contains Zinc Sulfate Monohydrate Tetracycline Hydrochloride

Moderate

Zinc and tetracycline don't work well when they're in your stomach together. Zinc can attach to tetracycline and stop your body from absorbing it properly. The same thing works the other way, so less zinc gets absorbed too. The result is that neither medicine may work as well as it should. If your doctor has prescribed both, ask them or your pharmacist how far apart to take them.

What do Major, Moderate and Minor mean?

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.
