Interactions with other medicines

Antacids, iron, zinc and calcium reduce the absorption of tetracyclines — separate them by a couple of hours. Tell your doctor if you take a blood thinner.

How to store Fasigyn DS

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
