Mesalamine enemas deliver medicine right to the lower colon where inflammation often starts. If you have mild to moderate ulcerative colitis affecting the rectum or left side of the colon, this treatment can reduce symptoms fast and with fewer overall side effects than some pills. This page gives clear, useful steps and safety tips so you can use them confidently.
Mesalamine (also called 5-ASA) fights inflammation at the site. Unlike oral pills, enemas coat the rectum and sigmoid colon directly, which helps control bleeding, urgency, and pain in that area. Doctors often prescribe them alongside oral meds or suppositories, depending on how much of the bowel is affected.
Follow your prescription, but here are common tips most people find helpful. Do it at bedtime so you can lie still and keep the liquid inside longer. Empty your bowels first. Warm the enema to body temperature by holding the sealed tube in warm (not hot) water; this reduces cramps. Remove the cap, lie on your left side with knees drawn up, gently insert the nozzle about 2–3 inches, and squeeze the contents in slowly. Stay lying down for at least 20–30 minutes if you can; longer retention helps the medicine work better.
If you leak a little, don’t panic. Use a pad, clean gently, and try again the next time. Keep extra towels and easy-to-remove bedding ready for the first few uses until you get comfortable with the routine.
Most regimens are once daily for induction of remission, then less often for maintenance, but follow the exact schedule your clinician gives you. Never change dose or stop suddenly without talking to your provider.
Common side effects include mild abdominal cramping, bloating, or a headache. Skin rash, fever, or worsening symptoms may be signs of a reaction — call your doctor right away. Rarely, mesalamine can affect the kidneys, so your doctor may check blood tests or urine periodically.
Mention all other meds you take, especially aspirin, blood thinners, or other anti-inflammatories. If you’re pregnant, trying to conceive, or breastfeeding, discuss risks and alternatives with your clinician before starting treatment.
Store enemas as directed — many need refrigeration after opening, others should be kept at room temperature. Dispose of used applicators safely. If the liquid looks cloudy or smells odd, don’t use it and contact the pharmacy.
Alternatives include oral mesalamine, suppositories (for very low rectal disease), corticosteroids for short-term flares, or advanced therapies for severe disease. Your gastroenterologist will weigh benefits and side effects to find the right plan.
If your symptoms don’t improve in a few weeks, get worse, or you develop fever, severe pain, or bloody diarrhea, contact your healthcare team. With the right instructions and a bit of practice, mesalamine enemas can be a straightforward and effective way to control lower-colon inflammation.
