Summary
Minocycline effectively treated acne in one-quarter of patients unresponsive to other antibiotics. However, vestibular side effects like dizziness were common, sometimes requiring treatment discontinuation.
Area of Science:
- Dermatology
- Pharmacology
Background:
- Acne vulgaris is a common skin condition.
- Antibiotic resistance is a growing concern in acne treatment.
- Tetracycline and erythromycin are common first-line treatments.
Purpose of the Study:
- To evaluate the efficacy and safety of minocycline in acne patients.
- To assess treatment outcomes for patients unresponsive to tetracycline and erythromycin.
Main Methods:
- Forty-seven acne patients received 100 mg of minocycline daily.
- Treatment outcomes and adverse events were monitored.
Main Results:
- Approximately 25% of patients showed a 50% or greater improvement.
- Common side effects included dizziness (5 patients), esophagitis (1 patient), and headaches (1 patient).
- Dizziness necessitated discontinuation in 4 out of 5 affected patients.
Conclusions:
- Minocycline can be an effective treatment option for acne refractory to other antibiotics.
- Vestibular side effects, particularly dizziness, are a significant concern and require patient counseling.
- Patients experiencing dizziness should avoid activities like driving or operating machinery.
