Imipramine, a common antidepressant, can rarely cause slate gray skin discoloration, particularly on sun-exposed areas. This case highlights imipramine-induced hyperpigmentation, emphasizing the need for awareness of drug-induced skin changes.
Area of Science:
- Dermatology
- Pharmacology
Background:
- Imipramine is a tricyclic antidepressant widely prescribed for mood disorders.
- Drug-induced hyperpigmentation is a rare but recognized adverse effect of certain medications.
Observation:
- A 63-year-old woman developed a bluish-gray facial and neck discoloration after over 20 years of imipramine use.
- The discoloration was primarily on sun-exposed areas.
Findings:
- Histopathology and clinical history confirmed the diagnosis of imipramine-induced hyperpigmentation.
- The study reviews other medications associated with hyperpigmentation and their staining characteristics.
Implications:
- Clinicians should be aware of the potential for imipramine to cause skin hyperpigmentation.
- Early recognition and diagnosis of drug-induced hyperpigmentation are crucial for patient management.
