Pristiq Oral Interactions

Your doctor or pharmacist may already be aware of any possible drug interactions and may be monitoring you for them. Do not start, stop, or change the dosage of any medicine before checking with your doctor or pharmacist first.

Taking certain medications with this product could result in serious (rarely fatal) drug interactions. Avoid taking MAO inhibitors (isocarboxazid, linezolid, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine) for 2 weeks before treatment, during treatment, and for at least 7 days after your last dose of desvenlafaxine. Consult your doctor or pharmacist for more information.

This drug should also not be used with the following medications because very serious (rarely fatal) interactions may occur:

  • weight loss drugs (e.g., sibutramine, phentermine)
  • tryptophan

If you are currently using any of these medications, tell your doctor or pharmacist before starting desvenlafaxine.

Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of:

  • drugs that can cause bleeding/bruising (e.g., aspirin, antiplatelet drugs such as clopidogrel, NSAIDs such as ibuprofen, "blood thinners" such as heparin/warfarin)

Desvenlafaxine is very similar to venlafaxine. Do not use medications containing venlafaxine while using desvenlafaxine.

Aspirin can increase the risk of bleeding when used with this medication (see above). If your doctor has directed you to take low-dose aspirin for heart attack or stroke prevention (usually at dosages of 81-325 milligrams a day), you should continue taking it unless your doctor instructs you otherwise. Discuss the risks and benefits with your doctor.

Also tell your doctor if you take any other drugs that increase serotonin, such as buspirone, dextromethorphan, lithium, meperidine, propoxyphene, SSRIs, other SNRIs, St. John's wort, drugs used to treat migraines such as "triptans" and dihydroergotamine, street drugs such as MDMA/"ecstasy," amphetamine. (See also Side Effects section.)

This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.
