How long after I finish my antibiotics (Rifaximin) treatment can I get laser hair removal done?

The reason to wait is because certain medications can lead to light sensitivity of the skin to UV radiation. All forms of light energy hair removal comes with a skin injury/burn risk and when some antibiotics are used this risk is increased. Options include reducing the energy of the laser being used or waiting until the light sensitivity of the medication has resolved. The industry standard is 8 weeks with most medications. For your case, Rifaximin does have a low incidence of light sensitivity in certain individuals and potentially can increase the chance of skin injury if your provider uses the same energy settings. Most providers will error on the side of caution and ask that you wait 8 weeks but some will offer the service with a lower setting ( both acceptable standards in my opinion). Because hair follicles will sometimes be in dormant phases an additional waiting period may actually increase effectiveness of the overall hair removal result. Thanks for the question
