Isotretinoin is a medication primarily used in the treatment of severe, recalcitrant acne. It’s derived from vitamin A and is a potent treatment for the most severe forms of acne, including cystic acne and acne that hasn’t responded to other treatments. Here are some key points about isotretinoin:

Acne Treatment: Isotretinoin is prescribed to individuals with severe acne that hasn’t improved with other treatments. This includes acne that’s nodular, cystic, or causes significant scarring.

Mechanism of Action: Isotretinoin works by targeting the sebaceous (oil) glands in the skin, reducing their size and activity. This leads to a significant decrease in sebum (skin oil) production. Since acne often involves excessive sebum production and clogged hair follicles, reducing sebum can help prevent the formation of acne lesions.

Oral Medication: It is typically administered in oral form (capsules or tablets) and is taken daily for several months. The dosage can vary depending on the severity of the acne and the individual’s response to the treatment.

Side Effects: Isotretinoin can have a range of side effects, including dry skin, dry and chapped lips, nosebleeds, dry eyes, muscle aches, and mood changes. Notably, it can have serious potential side effects, such as birth defects if taken during pregnancy and elevated levels of certain blood fats.

Regular Monitoring: Patients taking isotretinoin are closely monitored by healthcare providers during treatment. Women of childbearing potential are often required to use two forms of contraception due to the teratogenic (causing birth defects) potential of the drug.

Isotretinoin is highly effective, but it is reserved for severe cases of acne because of its potential side effects and risks. It should be taken only under the supervision of a healthcare provider who can monitor for side effects and ensure that patients are fully informed about its potential risks and precautions.
