Why is it necessary to stop allergy medications 48 hours prior to a laser hair removal session?

It's not necessary for you to discontinue the use of allergy medicines beforehand. Use of retin-A and topical products that can thin the skin or excessive sun exposure can be factors, as well as medications that increase your risk of light sensitivity.

The medication should not affect the treatment. There are a few meds that can increase the intensity of the laser, but those aren't allergy medications. Tetracycline or Sulfa meds can do this.
