Accutane is a wonderful medication, but it can be pretty hard on the liver. In fact, one of the main side effects seen in many people who take the medication is alteration of liver function enzymes. We check these regularly when someone is taking Accutane. The safest way to perform liposuction is to use the tumescent technique, or injection of large amounts of dilute local anesthetic solution. Lidocaine is the anesthetic used. Lidocaine can be toxic if high amounts are in the body. The liver has the job of clearing lidocaine from the bloodstream. If the liver is irritated, damaged, or not working properly as a result of a medication such as Accutane, toxic amounts of lidocaine can build up in the body and lead to very serious complications. I would advise any patient to wait until they were off Accutane, even if the liver appears to be working properly on the medication. It is simply not worth the risk.
