Treating Children and Adolescents

For the most part, the treatment approaches for children with IBD are based on adult experience. Children require individualized treatment that takes numerous factors into account: the specific disease manifestations (location of inflammation in the intestines, duration, prior response to therapy), the psychosocial adaptation of the child and family, and the child's age and size. Drug dosages also must be tailored, based upon the child's weight.

Children and adolescents are moving through a period of physical and emotional growth and development. Special consideration must be given to potential side effects and to issues of compliance with the prescribed treatment regimen. Regrettably, few well-designed clinical trials have generated data that specifically address the effectiveness of standard medications in children. However, the safety profile of these drugs has been supported by many years of use in pediatric clinical practice. Recently, the FDA mandated that the safety and effectiveness of new drugs be established in children and adolescents. Therefore, we anticipate that the number of studies of medications in the pediatric population will be dramatically increasing.

All of the medications used for adults with IBD are also used for children, and the indications and contraindications are similar. This section attempts to address the special considerations when the medications described above are prescribed for children and teenagers.


For treating mild-to-moderate, active ulcerative colitis and Crohn's colitis in children, 5-aminosalicylate (5-ASA) compounds remain the initial therapy in most cases. Although sulfasalazine clearly is effective, its use has generally declined in favor of mesalamine and olsalazine products, which have fewer side effects. Side effects from sulfasalazine may include headache, sun sensitivity rash, or other signs of sulfa allergy.

5-ASA may be taken rectally or orally. The dosages for a child are extrapolated on a per-kilogram basis from data in adults. The number of pills required (as many as 10-16 per day), and the frequency of administration for effectiveness (3-4 times per day) makes compliance with some mesalamines difficult for young patients. The dosage schedule will have to be carefully considered in light of the child's schedule. There are new formulations that are dosed once or twice daily and although they have not been formally tested in children, they are the same 5-ASA compound as other multi-dose medications. Should a dose be included or excluded during the school day? Parents may want to involve the child in this decision to aid compliance.

Special consideration must be given to the younger child who is unable to swallow tablets or capsules. Although a commercially available form of liquid sulfasalazine is no longer available, many pharmacies will formulate one if requested. Please review CCFA's fact sheet on helpful pill swallowing techniques.

For the child or adolescent with left-sided colonic inflammation, topical therapy with a 5-ASA suppository or enema often helps and has minimal potential side effects. Enema therapy may be a daunting prospect at first, but with education, support, and guidance, many patients and families adapt readily to this treatment.


These medications affect the body’s ability to launch and maintain an inflammatory process.  In addition, they work to suppress the immune system.  Corticosteroids are used in children with moderate-to-severe IBD.  Administered orally, rectally, or intravenously (through a vein), steroids are effective for short-term control of flare-ups but are not recommended to maintain remission in children due to undesirable long-term side effects, including stunted growth.  For that reason, corticosteroids are usually given in the lowest possible dosage for the shortest amount of time.  Frequent short-duration use, however, is not recommended.  Some side effects of corticosteroids include weight gain, insomnia, mood swings, osteoporosis, scalp hair loss or facial hair growth, acne, appearance of stretch marks, and increased susceptibility of infections and bruising. 


Specific antimicrobial agents may be beneficial in treating IBD, particularly distal (left-sided) colitis or perianal disease.

Metronidazole is used in children and adolescents with perianalCrohn's disease. It is also used as an alternative, or in addition, to sulfasalazineor steroids for Crohn's colitis. The dosage prescribed depends on the weight of the child and is conveniently given with meals. Teenagers should be told that alcohol and metronidazole do not mix and may result in severe nausea and vomiting. Long-term therapy may lead to reversible peripheral neuropathy (nerve damage); if this occurs, the drug must be stopped.

Ciprofloxacin has been shown to be effective for treating adults with colitis, and is used as an alternative to metronidazole for perianalCrohn's disease. In the past, ciprofloxacin was not recommended for pre-pubescent children. However, prior concerns have not been validated in clinical use in children with cystic fibrosis or IBD, and the drug's safety profile is quite positive.


The indications, contraindications, and adverse side effects of the immunomodulators—such as 6-MP and azathioprine—are not significantly different in children, when compared with adults. Azathioprineand 6-MP have been widely prescribed as maintenance therapy for children with Crohn's disease and ulcerative colitis who do not respond to standard medications. It has been shown that 6-MP is effective in children for controlling active disease, for steroid-dependent disease, and for perianaldisease. In addition, a newer study suggests that 6-MP may be effective in preventing the relapse of Crohn's disease after surgery. The risks and benefits of antimetabolite therapy with 6-MP or azathioprine should be discussed at length with the prescribing physician. However, these drugs should not necessarily be withheld from children based upon age alone. The steroid-sparing effects of this therapy, as well as its ability to control inflammation, may benefit children with IBD greatly. These treatments can minimize symptoms and optimize growth.

Limited information is available on the use of methotrexatein children with IBD. Its effectiveness in treating active Crohn's disease, as well as its potential as a maintenance drug for Crohn's, has been suggested in the adult and pediatric experience. Given the extensive use of this drug in children with rheumatoid arthritis, it would suggest relative safety. The significant potential side effect—scarring in the lungs or liver—appears to be quite uncommon in children. The principal side effects include nausea, vomiting, or headache following administration. A benefit of this drug is that only one dose per week is required. However, since the preferred administration is by injection, it may not appeal to young patients.

Biologic Therapies

The newest class of therapies to be used in IBD are proteins that selectively target key cells in the inflammatory cycle, thus short-circuiting the process.  These therapies are used to control moderate-tosevere disease and to maintain remission.  These medications are administered by injection or intravenous infusion on a schedule that varies from weekly to every few months, depending on the individual and the medication.  The FDA adds "however, there are serious risks associated with its use.  Patients and their families should always discuss with their physician the risks and benefits of using a medication before deciding to start treatment".

Nutrition—General Principles

Obviously, adequate nutrition is vital for all children who are actively developing and growing. In children with IBD adequate nutrition is crucial for the healing of inflammation while assuring normal growth. Therefore, a well-balanced diet is encouraged as part of the general health maintenance for the young IBD patient, but may be quite difficult to achieve. If there is no clear history of lactose (milk sugar) intolerance, eliminating dairy products from the diet is seldom suggested. These foods often constitute a major source of the child's daily caloric intake, and are important sources of dietary calcium; eliminating them may result in malnutrition. Oral nutritional supplements can be helpful for some children and adolescents who find it difficult to eat complete meals. Such supplements are only successful when their taste and use are found to be acceptable by the child. A daily multi-vitamin to assure adequate intake of important nutrients such as Vitamin D along with adequate calcium intake to maintain bone health are important nutritional goals. Consultation with a nutritionist is advised, as is involving the young person in ways to make sure that nutritional goals are achieved.


Nutrition as Therapy

There has been significant evidence to support the use of exclusive enteralnutrition (EEN) as therapy for patients with Crohn's disease. An elemental diet is one in which the protein constituents are broken down into their smallest building blocks called amino acids. Accomplishing an EEN diet requires the exclusive use of special liquid formulas and the exclusion of all other forms of food for the duration of this therapy.

Studies suggest that this type of diet can be successfully used as an alternative to medications such as corticosteroids to induce remission in pediatric patients with Crohn's disease. This evidence has been strongest in studies of newly diagnosed patients, especially those with involvement of the small intestine. There is more limited data to support this therapy for long-term maintenance partly because of the difficulty to chronically maintain this as the exclusive diet. Whether people on EEN can slowly introduce foods once in remission and continue "partial enteral nutrition" as therapy alone or in conjunction with medications as a long-term maintenance therapy remains an area of research and investigation. 

EEN is very safe and has the appeal of being drug free. It does involve a large investment on the part of the child or adolescent and the family since diet and eating are often such important cultural and quality of life issues. An additional issue with EEN has been that the formulas used are largely unpalatable and require delivery through a feeding tube (nasogastric tube or gastrostomy) in order to be tolerated. Recent research has shown that liquid nutrition in the form of polymeric formulas can be just as effective as elemental formulas. Polymeric formulas use whole proteins and, therefore, taste better than the elemental formulas. This allows patients to drink their exclusively liquid diets and not require feedings through a tube. However, research shows that in order for enteral nutrition to be effective as an anti-inflammatory treatment, it must be essentially the only source of calories for the patient.  For some people, this is difficult to maintain long term.  However, the nutritional benefits of supplemental formulas—either elemental or polymeric—can be seen even when they are used in addition to a regular diet. 

Accordingly, while nutritional therapy is a true non-drug form of therapy, it requires excellent communication between the patient, family, and health care personnel to achieve its use in the most effective manner.  

Other Drug Issues

Antidiarrheal agents
Many pediatric gastroenterologists support the use of loperamide (Imodium®) to alleviate the diarrhea of IBD if severe abdominal pain or profuse bleeding are absent. Anticholinergic drugs, codeine sulfate, or diphenoxylate hydrochloride with atropine sulfate (Lomotil®), are not recommended since they may result in significant side effects.

Acne medications
Acne, a common problem among adolescents, may affect young people with IBD even more severely.  It is often triggered or aggravated by steroid therapy. Isotretinoin is commonly prescribed for severe acne that does not respond to other treatments. However, the safety of isotretinoin in people with IBD has not been clearly established. There are reports of its use without any complications, but there also are anecdotal reports of patients who experienced flare-ups of their disease while on this medication.

Isotretinoin may occasionally trigger colitis-like symptoms, such as bleeding and diarrhea -- a condition called drug-induced hypersensitivity colitis. Rarely, isotretinoin has been linked to the appearance of chronic symptoms that mimic full-blown ulcerative colitis. However, there is no evidence that the medication actually causes IBD. Potential drug interactions may occur, most notably when isotretinoin is used with 6-MP.

Because of these concerns, initial therapy for acne in people with IBD should include topical treatment with cleansing agents or antibiotics, followed by oral antimicrobial agents. Isotretinoin should be used with caution and in consultation with all the physicians involved (e.g., the gastroenterologist as well as the dermatologist). Ideally, steroid-induced acne will improve by gradually tapering the steroid dose.

Treatment of IBD in the pediatric patient continues to improve, thanks to advances in therapy and clinical trials of new agents that are being conducted in children and teenagers. We hope that the information provided here will be helpful when patients and their physicians consult to determine the most effective course of treatment for each individual case.
