Alternative medicine

Alternative medicine is the use of a nonconventional approach instead of conventional medicine. Complementary medicine is a nonconventional approach used along with conventional medicine — sometimes called integrative medicine.

Make sure you understand the risks as well as possible benefits if you pursue alternative or complementary therapy. Don't replace conventional medical treatment or psychotherapy with alternative medicine. When it comes to depression, alternative treatments aren't a substitute for medical care.

Supplements

Examples of supplements that are sometimes used for depression include:

• St. John's wort. Although this herbal supplement isn't approved by the Food and Drug Administration (FDA) to treat depression in the U.S., it may be helpful for mild or moderate depression. But if you choose to use it, be careful — St. John's wort can interfere with a number of medications, such as heart drugs, blood-thinning drugs, birth control pills, chemotherapy, HIV/AIDS medications and drugs to prevent organ rejection after a transplant. Also, avoid taking St. John's wort while taking antidepressants because the combination can cause serious side effects.
• SAMe. Pronounced "sam-E," this dietary supplement is a synthetic form of a chemical that occurs naturally in the body. The name is short for S-adenosylmethionine (es-uh-den-o-sul-muh-THIE-o-neen). SAMe isn't approved by the FDA to treat depression in the U.S. It may be helpful, but more research is needed. SAMe may trigger mania in people with bipolar disorder.
• Omega-3 fatty acids. These healthy fats are found in cold-water fish, flaxseed, flax oil, walnuts and some other foods. Omega-3 supplements are being studied as a possible treatment for depression. While considered generally safe, in high doses, omega-3 supplements may interact with other medications. More research is needed to determine if eating foods with omega-3 fatty acids can help relieve depression.

Nutritional and dietary products aren't monitored by the FDA the same way medications are. You can't always be certain of what you're getting and whether it's safe. Also, because some herbal and dietary supplements can interfere with prescription medications or cause dangerous interactions, talk to your doctor or pharmacist before taking any supplements.

Mind-body connections

Integrative medicine practitioners believe the mind and body must be in harmony for you to stay healthy. Examples of mind-body techniques that may be helpful for depression include:

• Acupuncture
• Relaxation techniques such as yoga or tai chi
• Meditation
• Guided imagery
• Massage therapy
• Music or art therapy
• Spirituality
• Aerobic exercise

Relying solely on these therapies is generally not enough to treat depression. They may be helpful when used in addition to medication and psychotherapy.
