In general, military regulations prohibit the routine use of weight-loss prescription medications and only approve their short-term use under very specific conditions. However, each service has its own specific policies. See the documents linked below for details of those conditions.

Whenever possible, use a provider at your installation’s Medical Treatment Facility (MTF), as he/she should be knowledgeable about your service’s policy with regard to weight-loss medications, as well as any local controls that may exist. If for some reason you do go to a civilian provider, take your prescription to an MTF pharmacy; if your MTF pharmacy cannot fill such prescriptions from civilian providers, consult with your MTF before having the prescription filled elsewhere. This could help prevent problems with urinalysis testing and going against policy.

Just a reminder: This article refers to prescription medications for weight loss (that is, drugs), not dietary supplements. For information about weight-loss dietary supplements, please see our OPSS articles about weight loss.

Note that these policies/documents are updated at various times, so be sure to check with your MTF provider about any new changes to policy.

OPSS does not provide medical advice, and we always recommend talking to a military healthcare provider before taking any medications.
