Moderate Interactions
- Nonsteroidal Anti-inflammatory Drugs (NSAIDs)
- Nephrotoxic agents (e.g., tacrolimus, cyclosporine)
Monitoring
Baseline Monitoring
Rationale: To establish baseline and identify pre-existing renal impairment, as mesalamine can cause nephrotoxicity.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline and identify pre-existing hepatic impairment, as mesalamine can cause hepatotoxicity.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline and monitor for blood dyscrasias, especially if co-administered with thiopurines.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Periodically (e.g., every 3-6 months or as clinically indicated)
Target: Within normal limits for age and sex
Action Threshold: Significant increase in creatinine or BUN; consider dose adjustment or discontinuation.
Frequency: Periodically (e.g., every 3-6 months or as clinically indicated)
Target: Within normal limits
Action Threshold: Significant elevation; consider discontinuation.
Frequency: Periodically (e.g., every 3-6 months or as clinically indicated), more frequently if co-administered with thiopurines.
Target: Within normal limits
Action Threshold: Significant decrease in cell counts (e.g., leukopenia, thrombocytopenia); investigate and consider discontinuation.
Symptom Monitoring
- Abdominal pain
- Rectal bleeding
- Diarrhea
- Fever
- Rash
- Chest pain (pericarditis/myocarditis)
- Shortness of breath
- Unexplained fatigue
- Dark urine
- Yellowing of skin/eyes (jaundice)
- Changes in urination (e.g., decreased output)
Special Patient Groups
Pregnancy
Mesalamine is generally considered safe for use during pregnancy. Studies in animals have not shown harm to the fetus, and human data suggest a low risk. However, it should be used only if clearly needed.
Trimester-Specific Risks:
Lactation
Mesalamine and its metabolite are excreted in breast milk in small amounts. While generally considered compatible with breastfeeding, monitor the infant for diarrhea or other adverse effects.
Pediatric Use
Safety and efficacy have not been established in pediatric patients. Use in children should be based on careful consideration of risks and benefits by a specialist.
Geriatric Use
Use with caution in elderly patients, especially those with pre-existing renal or hepatic impairment, due to increased susceptibility to adverse reactions. Monitor renal function closely.
Clinical Information
Clinical Pearls
- Instruct patients to administer the enema at bedtime and retain it for as long as possible (preferably overnight, 8 hours) to maximize local contact and efficacy.
- Ensure proper administration technique: shake the bottle well, lie on the left side with the lower leg extended and the upper leg flexed forward, insert the applicator tip gently, and squeeze the bottle slowly.
- Mesalamine rectal enema is primarily for distal ulcerative colitis (proctitis, proctosigmoiditis) and may not be effective for more extensive disease.
- Patients should be advised that the enema may stain fabrics.
- Monitor for signs of mesalamine-induced acute intolerance syndrome (e.g., cramping, acute abdominal pain, bloody diarrhea, fever, headache, rash), which may mimic a flare of inflammatory bowel disease.
Alternative Therapies
- Corticosteroid rectal preparations (e.g., hydrocortisone enema, budesonide rectal foam)
- Oral 5-aminosalicylates (e.g., oral mesalamine, sulfasalazine)
- Immunomodulators (e.g., azathioprine, mercaptopurine) for more severe or refractory disease
- Biologic agents (e.g., infliximab, adalimumab) for moderate to severe disease
- Janus kinase (JAK) inhibitors (e.g., tofacitinib)
