Pediatric depression is increasingly recognized in the United States. The Centers for Disease Control and Prevention estimates that 1 in 20 children is diagnosed with anxiety or depression.1 When discussing treatment options, patients or caregivers often express an interest in complementary and alternative medicine (CAM). Nutritional supplements are touted to the public as less toxic or more effective than conventional drugs because they are “natural” and their efficacy is based on knowledge gained over thousands of years.2 Due to the black-box warnings on antidepressants issued by the US Food and Drug Administration (FDA) and recent negative media generated toward the scientific community, parents may shy away from evidence-based medications for their children.3,4 Providers play an important role in explaining the risks and benefits associated with nutritional supplements as well as prescription medications.

Guideline recommendations

Only 2 drugs, fluoxetine and escitalopram, are approved by the FDA to treat childhood depression.5,6 Nevertheless, consensus guidelines recommend fluoxetine, citalopram, and sertraline as first-line treatments for moderate to severe depression in pediatric patients. Venlafaxine, bupropion, mirtazapine, duloxetine, and lithium are alternatives for individuals with inadequate clinical response.7

Pediatric practice guidelines do not suggest herbal supplements as treatment options. However, the American Psychiatric Association’s (APA) depression guideline discusses CAM. The guideline states that folate is a reasonable, low-risk, adjunctive strategy but more data is necessary to establish a role for St. John’s wort, S-adenosyl methionine (SAMe), and omega-3 fatty acids (O3FA).8

Necessary precautions

Federal law does not require companies to prove safety or efficacy of dietary supplements prior to manufacturing.9 Because rigorous clinical testing is not mandated, dosing is often recommended upon small, poorly designed studies. Significant uncertainty surrounds the long-term consequences of exposure to some herbal remedies for which the toxicity profiles are incompletely characterized.2

There is also considerable risk of delaying therapy with an evidence-based medication, especially for suicidal patients. Additionally, drug-drug interactions may occur with herbal supplements and prescription medications, rendering pharmacotherapy ineffective or even dangerous. Finally, although supplements are readily available over-the-counter, they are typically not covered by insurance. Families may face significant financial burden when purchasing herbal products from a reputable source.

The Table reviews these over-the-counter supplements and the corroborating study data for each product.

 

Whereas there may be theoretical benefit or literature demonstrating positive outcomes in different populations, the following supplements were excluded from this review due to a lack of data in pediatric depression: acetyl-l-carnitine, B vitamins, dehydroepiandrosterone, folic acid, glutamine, 5-hydroxytryptophan, inositol, iron, phenylalanine, probiotics, saffron, turmeric, and tyrosine.
