Mesalamine

What is MESALAMINE?

(MESALAMINE) This medication is used to treat a certain bowel disease (ulcerative colitis). It helps to reduce symptoms of ulcerative colitis such as diarrhea, rectal bleeding, and stomach pain. Mesalamine belongs to a class of drugs known as aminosalicylates. It works by decreasing swelling in the colon.

How should I use MESALAMINE?

Take this medication by mouth with a meal as directed by your doctor, usually once daily. Swallow this medication whole. Do not crush, chew, or break the tablets. Doing so can keep the drug from being released properly into the colon. Drink plenty of fluids during treatment with this medication unless otherwise directed by your doctor. This will help prevent kidney stones. The dosage is based on your medical condition and response to treatment. For children, the dosage is also based on weight. Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Tell your doctor if your condition does not improve or if it worsens.

What should I tell my health care provider before I take MESALAMINE?

Before taking mesalamine, tell your doctor or pharmacist if you are allergic to it; or to other aminosalicylates (such as balsalazide, olsalazine); or to salicylates (such as aspirin, salsalate); or to sulfasalazine; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. Before using this medication, tell your doctor or pharmacist your medical history, especially of: kidney disease, liver disease, stomach blockage (such as pyloric stenosis). This medication may make you more sensitive to the sun, especially if you have skin problems (such as atopic dermatitis, eczema). Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness. Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). This medication is similar to aspirin. Children and teenagers younger than 18 years should not take aspirin or aspirin-related medications (such as salicylates) if they have chickenpox, flu, or any undiagnosed illness, or if they have recently received a vaccine. In these cases, taking aspirin increases the risk of Reye's syndrome, a rare but serious illness. During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor. This medication passes into breast milk and may have undesirable effects on a nursing infant. Consult your doctor before breastfeeding.

What may interact with MESALAMINE?

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval. Mesalamine is very similar to balsalazide, olsalazine, and sulfasalazine. Do not use medications containing balsalazide, olsalazine, or sulfasalazine while using mesalamine. This medication may interfere with certain lab tests (such as urine normetanephrine levels), possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.

What if I miss a dose of MESALAMINE?

If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose. Take your next dose at the regular time. Do not double the dose to catch up.

What side effects may I notice from receiving MESALAMINE?

Headache or abdominal pain may occur. If either of these effects lasts or gets worse, tell your doctor or pharmacist promptly. Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Rarely, mesalamine can worsen ulcerative colitis. Tell your doctor right away if your symptoms worsen after starting this medication (such as increased abdominal pain/cramping, bloody diarrhea). Tell your doctor right away if you have any serious side effects, including: nausea/vomiting that doesn't stop, signs of kidney problems (such as change in the amount of urine, blood in the urine), dark urine, severe stomach/abdominal pain, yellowing eyes/skin, chest pain, shortness of breath. A very serious allergic reaction to this drug is rare.
