What Causes Cystic Acne?

Reaction To Certain Medication

Certain drugs may cause or at least contribute to cystic acne or flare-ups. This may be a result of particular ingredients in the drugs, or it may be a side effect. A reaction to medication is uncommon for cystic acne patients, but it is a known side effect of medications like lithium or anticonvulsant drugs. Other medications linked to acne or acne-like flare-ups include corticosteroids and barbiturates. Dehydroepiandrosterone supplements, which are made from a steroid hormone, and medications that contain bromides or iodides can also cause acne-like symptoms. Patients should consult their physician or dermatologist to assist them in the development of an appropriate treatment plan should medications become an issue related to cystic acne for them.
