Drug induced hyperpigmentation is a form of skin discoloration that occurs as a reaction to certain medications. It presents as patches or areas of darkened skin that may appear brown, gray, blue, or slate colored, depending on the underlying cause. This type of pigmentation can develop gradually and may persist even after the medication is discontinued.
02
What Causes Drug induced hyperpigmentation?
Drug induced hyperpigmentation develops when medications alter how pigment is produced, stored, or deposited in the skin. In some cases, the drug or its metabolites accumulate directly in the skin, while in others, the medication stimulates increased melanin production or causes photosensitivity that leads to discoloration.
Common medications associated with drug induced hyperpigmentation:
Antibiotics Such As Minocycline
Antimalarial Medications
Chemotherapy Agents and Certain Anti Inflammatory Drugs
Heart Medications like Amiodarone
Mood or Psychiatric Medications

Treating Drug induced hyperpigmentation at Aesthetic Solutions
Treatment of drug induced hyperpigmentation focuses on both preventing further darkening and improving existing discoloration. When possible, adjusting or discontinuing the causative medication is an important first step. Strict sun protection is essential, as ultraviolet exposure can worsen pigmentation.
Topical therapies may provide some benefit, though they are often limited when pigment is deeper in the skin. Laser treatments, particularly picosecond lasers and Q switched Alexandrite lasers, are commonly used to target and break down deeper pigment, allowing for gradual clearing over a series of treatments.
