The Food and Drug Administration issued a warning Wednesday regarding the use of Carbolith capsules, a treatment for manic-depressive illness that is distributed by a Canadian company.

The drug is not approved by the FDA, but Americans could purchase it on the Internet.

Valeant Canada Limited issued a recall of Carbolith 150mg capsules because the company said the product may not deliver adequate amounts of the drug to ensure effective treatment, the warning said.
