Pentasa enemas are a prescription medicine that treat Ulcerative Colitis in the last part of the large bowel, known as Distal Ulcerative Colitis (left sided colitis).
Pentasa enemas contain mesalazine (also known as 5-aminosalicylic acid or 5-ASA), that work by coming into direct contact with the inflamed tissue in the large bowel, treating the inflammation.
How to use Pentasa Enemas
Enemas are a way of administering some medicines via the rectum.
If possible, go to the toilet and empty your bowels before using an enema. The enema will work better if the bowel has been emptied.
Pentasa enemas are normally used at bedtime.
You may want to use a protective covering over the area where you will be lying down to administer the enema as it could stain some surfaces.
If necessary, a water-soluble lubricant, such as KY jelly, can be applied to the tip of the enema bottle to help with insertion.
Administer the enema as follows:
- Immediately before use take the enema bottle out of the aluminium foil pack and shake it well.
- Hold the enema in one hand with the nozzle tip pointing towards you and apply slight pressure. With the other hand, break the seal of the bottle by twisting the nozzle one full turn (360 degrees). The nozzle should be pointing in the same direction as it was before turning.
- Put your hand in one of the plastic disposal bags provided.
- Hold the container in your right hand as shown in the picture, with the nozzle tip pointing towards you, and your fingers wrapped around the wavy edge.
- To administer the enema, lie on your left side with the left leg straight and the right leg bent forward for balance. Carefully insert the applicator tip into the rectum. Insertion may be easier if you bear down as if having a bowel movement. Gently squeeze the enema out of the bottle. Maintain sufficient constant hand pressure while squeezing the bottle to empty the contents in less than 30 to 40 seconds. Once the bottle is empty, withdraw the tip with the bottle still compressed.
- The enema liquid should be retained in the bowel. Remain relaxed in the administration position for 5-10 minutes or until the urge to pass the enema liquid has disappeared.
- Roll the plastic disposal bag over the empty bottle. Discard it and wash your hands.
It is important to know that when your disease is active and at its worst, it may be difficult to retain the full 100mL enema. Even if you retain a small portion of the enema, do not be discouraged, it is a step in the right direction.
