The ingredients also may cause additional side effects, including burning, dryness, itching, peeling, redness, and slight swelling where the product is applied, the agency says.
Symptoms of a bad reaction to a topical acne medication may include:
- Throat tightness.
- Shortness of breath.
- Low blood pressure.

If you have these symptoms after using a topical acne medication, stop using the product immediately and seek medical attention, the FDA says.
