  • a stomach condition called pyloric stenosis;
  • a history of allergy to sulfasalazine (Azulfidine);
  • a heart condition such as congestive heart failure;

How should I take mesalamine oral (Asacol HD)?

Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

Take mesalamine with a full glass of water.

Mesalamine can usually be taken with or without food. Follow your doctor's instructions.

Do not crush, break, or chew a mesalamine tablet or capsule. Swallow the pill whole.
