Which drugs or supplements interact with Zoloft?

All SSRIs, including Zoloft, should not be taken with any of the monoamine oxidase inhibitor (MAOI) class of antidepressants, for example

  • isocarboxazid (Marplan),
  • phenelzine (Nardil),
  • tranylcypromine (Parnate),
  • selegiline (Eldepryl, Emsam, Elazar), and
  • procarbazine (Matulane).

Other drugs that inhibit monoamine oxidase include

Such combinations may lead to confusion, high blood pressure, tremor, hyperactivity, coma, and death. (A period of 14 days without treatment should lapse when switching between Zoloft and MAOIs.) Similar reactions occur when Zoloft is combined with other drugs for example, tryptophan, St. John’s wort, meperidine (Demerol, Meperitab), tramadol (ConZip, Synapryn FusePaq, Ultram) that increase serotonin in the brain.

Cimetidine (Cimetidine Acid Reducer, Tagamet HB ) may increase the levels in blood of Zoloft by reducing the elimination of Zoloft by the liver. Increased levels of Zoloft may lead to more side effects.

Zoloft increases the blood level of pimozide (Orap) by 40%. High levels of pimozide can affect electrical conduction in the heart and lead to sudden death. Therefore, patients should not receive treatment with both pimozide and Zoloft.

Through unknown mechanisms, Zoloft may increase the blood thinning action of warfarin (Coumadin, Jantoven). The effect of warfarin should be monitored when Zoloft is started or stopped.

Is Zoloft safe to use during pregnancy or while breastfeeding?

  • Use of sertraline during the 3rd trimester of pregnancy may lead to adverse effects in the newborn.
  • Use of sertraline by nursing mothers has not been adequately evaluated.
