About sertraline

Sertraline is a member of the selective serotonin reuptake inhibitor (SSRI) family of drugs used to treat people with depression.

Overview

Try these helpful products which may be beneficial if taken with this medicine

• Chromium
• Taking 200 to 400 mcg of chromium each day might enhance the antidepressant effect in some people taking sertraline for depression

• Ginkgo
• Some individuals taking sertraline might develop unwanted sexual side effects; taking 240 mg per day of the herb Ginkgo biloba might prevent this complication

Interactions with Supplements

Chromium

There have been five case reports of chromium supplementation (200-400 mcg per day) significantly improving mood in people with a type of depression called dysthymic disorder who were also taking sertraline.¹ These case reports, while clearly limited and preliminary in scope, warrant a controlled trial to better understand the benefits, if any, of chromium supplementation in people taking this drug.

5-Hydroxytryptophan (5-HTP) and L-tryptophan

Sertraline increases serotonin activity in the brain. 5-HTP and L-tryptophan are converted to serotonin in the brain, and taking either of these compounds with sertraline may increase sertraline-induced side effects.

In one report, dietary supplements of L-tryptophan (available only by prescriptions from special compounding pharmacists) taken with paroxetine (a drug similar to sertraline) caused headache, sweating, dizziness, agitation, restlessness, nausea, vomiting, and other symptoms.² On the other hand, the combination of 45 mg DL-tryptophan (a synthetic variation of L-tryptophan) per pound of body weight (a relatively high dose) with zimelidine, a drug with a similar action to sertraline, did not cause these side effects in another trial.³ Some doctors have used small amounts of L-tryptophan in combination with SSRIs, to increase the effectiveness of the latter. However, because of the potential for side effects, 5-HTP and L-tryptophan should never be taken in combination with sertraline or other SSRIs, unless the combination is being closely monitored by a doctor. Foods rich in L-tryptophan do not appear to interact with sertraline or other SSRIs.

Sodium

SSRI drugs, including sertraline, have been reported to cause sodium depletion.^{4, 5, 6} The risk for SSRI-induced sodium depletion appears to be increased during the first few weeks of treatment in women, the elderly, and patients also using diuretics. Doctors prescribing SSRI drugs, including sertraline, should monitor their patients for signs of sodium depletion.

Interactions with Herbs

Ginkgo biloba

In three men and two women treated with fluoxetine or sertraline (SSRI drugs closely related to paroxetine) for depression who experienced sexual dysfunction, addition of Ginkgo biloba extract (GBE) in the amount of 240 mg per day effectively reversed the sexual dysfunction.⁷ This makes sense because ginkgo has been reported to help men with some forms of erectile dysfunction.⁸

St. John's wort(Hypericum perforatum)

One report described a case of serotonin syndrome in a patient who took St. John's wort and trazodone, a weak SSRI drug.⁹ The patient reportedly experienced mental confusion, muscle twitching, sweating, flushing, and ataxia. In another case, a patient experienced grogginess, lethargy, nausea, weakness, and fatigue after taking one dose of paroxetine (Paxil®, another SSRI drug) after ten days of St. John's wort use.¹⁰

Other Interactions

Food

Results of two nonblinded randomized studies in healthy people suggest sertraline may be taken with or without food.¹¹

Alcohol

SSRI drugs, including sertraline, may cause dizziness or drowsiness.¹² Alcohol may intensify these effects and increase the risk of accidental injury. Alcohol should be avoided during sertraline therapy.
