The following clinically significant adverse reactions are described elsewhere in labeling:

  • Hypercorticism and adrenal axis suppression
  • Symptoms of steroid withdrawal in those patients transferred from other systemic corticosteroids
  • Increased risk of infection
  • Other corticosteroid effects

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.


The data described below reflect exposure to ENTOCORT EC in 520 patients with Crohn’s disease, including 520 exposed to 9 mg per day (total daily dose) for 8 weeks and 145 exposed to 6 mg per day for one year in placebo controlled clinical trials. Of the 520 patients, 38% were males and the age range was 17 to 74 years.

Treatment Of Mild To Moderate Active Crohn’s Disease

The safety of ENTOCORT EC was evaluated in 651 adult patients in five clinical trials of 8 weeks duration in patients with active mild to moderate Crohn’s disease. The most common adverse reactions, occurring in greater than or equal to 5% of the patients, are listed in Table 1.

The incidence of signs and symptoms of hypercorticism reported by active questioning of patients in 4 of the 5 short-term clinical trials are displayed in Table 2.

Maintenance Of Clinical Remission Of Mild To Moderate Crohn’s Disease

The safety of ENTOCORT EC was evaluated in 233 adult patients in four long-term clinical trials (52 weeks) of maintenance of clinical remission in patients with mild to moderate Crohn’s disease. A total of 145 patients were treated with ENTOCORT EC 6 mg once daily.

The adverse reaction profile of ENTOCORT EC 6 mg once daily in maintenance of Crohn’s disease was similar to that of short-term treatment with ENTOCORT EC 9 mg once daily in active Crohn’s disease. In the long-term clinical trials, the following adverse reactions occurred in greater than or equal to 5% and are not listed in Table 1: diarrhea (10%); sinusitis (8%); infection viral (6%); and arthralgia (5%).

Signs/symptoms of hypercorticism reported by active questioning of patients in the long-term maintenance clinical trials are displayed in Table 3.

The incidence of signs/symptoms of hypercorticism as described above in long-term maintenance clinical trials was similar to that seen in the short-term treatment clinical trials.

Less Common Adverse Reactions In Treatment And Maintenance Clinical Trials

Less common adverse reactions (less than 5%), occurring in adult patients treated with ENTOCORT EC 9 mg (total daily dose) in short-term treatment clinical studies and/or ENTOCORT EC 6 mg (total daily dose) in long-term maintenance clinical trials, with an incidence are listed below by system organ class:

Bone Mineral Density

A randomized, open, parallel-group multicenter safety clinical trial specifically compared the effect of ENTOCORT EC (less than 9 mg per day) and prednisolone (less than 40 mg per day) on bone mineral density over 2 years when used at doses adjusted to disease severity. Bone mineral density decreased significantly less with ENTOCORT EC than with prednisolone in steroid-naive patients, whereas no difference could be detected between treatment groups for steroid-dependent patients and previous steroid users. The incidence of symptoms associated with hypercorticism was significantly higher with prednisolone treatment.

Clinical Laboratory Test Findings

The following potentially clinically significant laboratory changes in clinical trials, irrespective of relationship to ENTOCORT EC, were reported in greater than or equal to 1% of patients: hypokalemia, leukocytosis, anemia, hematuria, pyuria, erythrocyte sedimentation rate increased, alkaline phosphatase increased, atypical neutrophils, c-reactive protein increased and adrenal insufficiency.

Pediatrics –Treatment Of Mild To Moderate Active Crohn’s Disease

Adverse reactions reported in pediatric patients 8 to 17 years of age, who weigh more than 25 kg, were similar to those reactions described above in adult patients.

Postmarketing Experience

The following adverse reactions have been reported during post-approval use of ENTOCORT EC. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Immune System Disorders: Anaphylactic reactions

Nervous System Disorders: Benign intracranial hypertension

Psychiatric Disorders: Mood swings.
