Drug-induced acne, also known as acne medicamentosa, can manifest as acneiform eruptions or exacerbation of existing acne due to certain medications. It may present with various characteristics such as:

1. Appearance: Drug-induced acne can appear as multiple small red or pink bumps, papules, pustules, or cysts on the face, chest, back, or other areas of the body.

2. Distribution: The acne may differ from typical acne in its distribution pattern, sometimes being more widespread or appearing in unusual areas.

3. Timing: It often occurs shortly after starting a new medication, but can also develop after prolonged use of certain drugs.

4. Types of Acne Lesions: Drug-induced acne can involve a mix of inflammatory and non-inflammatory lesions, such as pustules, nodules, and comedones.

5. Itching or Burning Sensation: Some individuals may experience itching or a burning sensation in the affected areas.

If you suspect that your new medication is causing acne, it is advisable to consult your healthcare provider or dermatologist for a proper evaluation and management.
