Clarus is a medication that treats severe acne. The generic ingredient in Clarus is isotretinoin, which belongs to a class of drugs called retinoids. Because of its potential for very serious side effects, the drug is reserved for people with the most severe acne that has not responded to other medication.
Clarus is used to treat severe nodular and/or inflammatory acne, acne conglobata and recalcitrant acne. These are severe forms of acne.
Since its approval in 1982, isotretinoin has been considered a breakthrough treatment for severe acne. Isotretinoin is the most potent inhibitor of sebum (natural oil) production. It also reduces skin bacteria (P. acnes), the clogging of pores, and inflammation.
Your doctor will prescribe the right dosage for you depending on your weight and the severity of the acne. The usual starting dose is 0.5mg for every kilogram of body weight daily for two to four weeks. Initially, the condition might temporarily get worse. The complete course of treatment usually lasts 12 to 16 weeks. You may see additional improvement for up to several months after a course of isotretinoin has been completed. This medication is taken orally.
These may not be all the side effects of Clarus.
Do not use Clarus if you are pregnant or breastfeeding. Do not take tetracyclines (antibiotics) or vitamin A supplements with Clarus. If you have high blood fat, liver disease, or kidney disease you should not use this medication.
You may be asked to sign an informed consent form before starting treatment with this medication. Isotretinoin can cause birth defects, miscarriage or premature birth. Discuss the risks and benefits of taking this medication. Some patients have developed depression and other serious mental health issues.
