Monitoring
Baseline Monitoring
Rationale: To establish baseline and identify pre-existing renal impairment, as mesalamine can cause renal toxicity.
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 (rare).
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Periodically during treatment, especially in patients with known renal disease or those receiving concomitant nephrotoxic drugs. Annually for long-term use.
Target: Within normal limits or stable from baseline.
Action Threshold: Significant increase in creatinine or BUN; consider dose adjustment or discontinuation.
Frequency: Periodically during treatment, especially if symptoms of hepatic dysfunction develop. Annually for long-term use.
Target: Within normal limits or stable from baseline.
Action Threshold: Significant elevation of liver enzymes; consider discontinuation.
Frequency: Periodically during treatment, especially if unexplained bleeding, bruising, fever, or sore throat occur.
Target: Within normal limits.
Action Threshold: Significant decrease in blood counts (e.g., leukopenia, thrombocytopenia); consider discontinuation.
Symptom Monitoring
- Worsening of ulcerative colitis symptoms (e.g., increased rectal bleeding, diarrhea, abdominal pain)
- Signs of renal dysfunction (e.g., decreased urine output, swelling in ankles/feet)
- Signs of liver dysfunction (e.g., yellowing of skin/eyes, dark urine, persistent nausea/vomiting, abdominal pain)
- Signs of hypersensitivity reaction (e.g., rash, fever, difficulty breathing, chest pain)
- Signs of acute intolerance syndrome (e.g., cramping, acute abdominal pain, bloody diarrhea, fever, headache, rash)
- Signs of blood dyscrasias (e.g., unexplained bruising, bleeding, persistent sore throat, fever)
Special Patient Groups
Pregnancy
Generally considered safe for use during pregnancy. Studies in pregnant women have not shown an increased risk of fetal abnormalities. However, use only if clearly needed and potential benefits outweigh risks.
Trimester-Specific Risks:
Lactation
Mesalamine and its metabolite are excreted in breast milk in small amounts. Generally considered compatible with breastfeeding, but monitor breastfed infant for diarrhea.
Pediatric Use
Safety and efficacy have not been established in pediatric patients. Use in children is off-label and typically reserved for specific cases under specialist supervision.
Geriatric Use
Use with caution in elderly patients, as they are more likely to have decreased renal function. Monitor renal function closely. Start at the lower end of the dosing range.
Clinical Information
Clinical Pearls
- Mesalamine rectal enema is designed for local action in the rectum and sigmoid colon, making it highly effective for proctosigmoiditis with minimal systemic side effects.
- Instruct patients to administer the enema at bedtime and try to retain it overnight for optimal efficacy.
- Patients should be advised that the enema may stain clothing or bedding.
- Monitor renal function, especially in patients with pre-existing kidney disease or those on concomitant nephrotoxic medications.
- Acute intolerance syndrome (cramping, abdominal pain, bloody diarrhea, fever, headache, rash) is a rare but important adverse effect; if suspected, discontinue therapy immediately.
Alternative Therapies
- Mesalamine suppositories (for proctitis)
- Oral mesalamine formulations (e.g., tablets, capsules)
- Corticosteroid enemas or foams (e.g., hydrocortisone, budesonide)
- Immunomodulators (e.g., azathioprine, mercaptopurine) for more severe or extensive disease
- Biologic agents (e.g., infliximab, adalimumab) for moderate to severe disease
