Talk to your doctor if you are breastfeeding or intend to breastfeed.

Your doctor can discuss with you the risks and benefits involved.

The underlying condition itself (inflammatory bowel disease) may increase risks for the pregnancy outcome.

Children

  • Do not give PENTASA to a child 12 years old or under.

The safety and effectiveness of PENTASA in this age group have not been established.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

There is no information available on interactions between PENTASA and other medicines. However, mesalazine belongs to a group of medicines called salicylates that may interfere with some medicines.

Medicines that may have their effects increased if used with PENTASA include:

  • anti-coagulants which are used to thin blood or stop blood clots (e.g. warfarin). When PENTASA is used with these medicines, it may increase the medicine’s effects on thinning your blood.
