Drugs are typically tested and approved for use in adult patients. This often means that treatment regimens for children and teens are determined from the results of studies done on adults. Treating children with the same medications as adults can be challenging. Increasingly, treatments are being studied on children as well as adults, particularly for diseases such as IBD that are found often in younger people.
The newer drugs in this class, mesalamine (Asacol, Pentasa) and olsalazine, tend to have fewer side effects than sulfasalazine. These formulations do not contain sulfa. Instead, the active ingredient (5-ASA) is enclosed in a coating that keeps it intact until it reaches the colon. This results in more of the drug being released into the area where it is needed (the intestine). Common side effects include headache, abdominal pain, and diarrhea.
The 5-ASA drugs come in several forms. They may be taken orally or rectally. These medications may need to be taken in three or four doses throughout the day. Younger patients may have trouble working their drug schedule into their daily school routine or in remembering to take their medication so many times each day. Oral solutions of these drugs are not readily available.
Oral corticosteroids are used for mild-to-moderate disease, with dosages for children calculated based on their weight in kilograms. Steroids given intravenously in a hospital setting are tapered down to a level that can be given orally as soon as possible. Topical steroids are used primarily when the location of the active disease is near the end of the colon and in the rectum. They may be given as an enema or as a foam that is held in the rectum.
Side effects are common with the oral and intravenous forms of corticosteroids, and less common with the enema and foam formulations. Most side effects will decrease when the drug is tapered down and discontinued, but some adverse effects are permanent. Common side effects that may be especially troubling to children and adolescents include acne, facial hair growth, weight gain, and rounding of the face. Corticosteroids are also associated with reduced bone mass and delayed development and growth in children. Corticosteroids do not make children more prone to catching colds or the flu, but children taking corticosteroids are more susceptible to becoming infected with chickenpox (varicella) and other forms of the herpes virus.
Side effects of metronidazole include diarrhea, vomiting, and numbness in the hands and feet which may be from reversible nerve damage (peripheral neuropathy). Metronidazole should not be taken with alcoholic drinks, as it can cause severe nausea and vomiting. Ciprofloxacin is associated with side effects such as nausea, vomiting, diarrhea, and headache.
