Ketamine is still being researched to treat fibromyalgia.
The use of ketamine for a treatment option in fibromyalgia is still very new. Actually, it hasn't gotten much further than standard research and clinical trials. Researchers are still studying the different ways that they can effectively administer the drug to patients.
Intravenous ketamine has been approved by the FDA, but the infusion of the medication is still up for debate. While short-term infusion, one dose over 4 hours a day, showed positive results, there were no long-term effects. Long-term use of the drug, which is 4 to 14 days of continuous dosages, has helped patients for up to 3 months after their final treatment.
