A rare case of misoprostol hypersensitivity

Area of Science:

• Obstetrics & Gynecology
• Pharmacology
• Clinical Medicine

Background:

• Medical abortion with mifepristone-misoprostol is a widely accepted, safe, and effective method for pregnancy termination.
• The regimen is often recommended for home-based use due to its favorable safety profile and transient side effects.
• Misoprostol is generally well-tolerated, with mild and temporary adverse effects commonly reported.

Observation:

• This report details a rare case of hypersensitivity reaction to sublingual misoprostol during early pregnancy termination.
• The patient experienced a severe reaction requiring immediate medical attention.
• Timely diagnosis and prompt intervention were crucial in managing the potentially life-threatening airway obstruction.

Findings:

• Hypersensitivity reactions, though rare, can occur with sublingual misoprostol use in medical abortions.
• Early recognition and management of such reactions are critical to prevent severe complications like airway compromise.
• This case underscores the importance of preparedness for adverse drug reactions even with established safe protocols.

Implications:

• Healthcare providers should maintain awareness of rare hypersensitivity reactions to misoprostol.
• Patient counseling for medical abortion, particularly for outpatient or home-based care, must include information on potential severe adverse events.
• Vigilance and prompt medical support are essential to ensure patient safety during medical abortion procedures.
