Pentasa is manufactured by Shire USA, Inc.
Pentasa belongs to a group of medications called aminosalicylates. It is thought that the drug works by inhibiting the production of inflammatory chemicals in the lining of the
colon. Pentasa decreases the production of prostaglandins and leukotrienes, chemicals that lead to the inflammation caused by ulcerative colitis.
The capsules are controlled-release, meaning they dissolve slowly over time. This allows the medication to be released throughout the gastrointestinal tract.
In clinical studies, people taking Pentasa experienced fewer
symptoms of ulcerative colitis (including fever, trips to the toilet, bleeding, and pain) when compared to those not taking the medication.
General considerations for when and how to take Pentasa include the following:
- The medication comes in capsule form. It is usually taken by mouth four times daily.
- You can take Pentasa with or without food. If the medicine bothers your stomach, try taking it with food.
- The capsules are controlled-release and should not be opened, chewed, or crushed.
- Pentasa should be taken at the same times each day to maintain an even level in your blood.
- For the medication to work properly, it must be taken as prescribed. Pentasa will not work if you stop taking it.
The dose of Pentasa your healthcare provider recommends will vary, depending on a number of factors, including:
- Other medical conditions you may have
- Other medications you may be taking.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
As with any medicine, side effects are possible with Pentasa. However, not everyone who takes the medication will experience side effects. In fact, most people tolerate it well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious side effects are less common.
