Antidepressant Medicines, Depression and Other Serious Mental Illnesses, and Suicidal Thoughts or Actions
Talk to your healthcare provider about:
- all risks and benefits of treatment with antidepressant medicines
- all treatment choices for depression or other serious mental illness
What is the most important information I should know about antidepressant medicines, depression and other serious mental illnesses, and suicidal thoughts or actions?
- Antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, and young adults within the first few months of treatment.
- Depression and other serious mental illnesses are the most important causes of suicidal thoughts and actions. Some people may have a particularly high risk of having suicidal thoughts or actions. These include people who have (or have a family history of) bipolar illness (also called manic-depressive illness) or suicidal thoughts or actions.
- How can I watch for and try to prevent suicidal thoughts and actions?
- Pay close attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. This is very important when an antidepressant medicine is started or when the dose is changed.
- Call the healthcare provider right away to report new or sudden changes in mood, behavior, thoughts, or feelings.
- Keep all follow-up visits with the healthcare provider as scheduled. Call the healthcare provider between visits as needed, especially if you have concerns about symptoms.
Call a healthcare provider right away if you have any of the following symptoms, especially if they are new, worse, or worry you:
- thoughts about suicide or dying
- attempts to commit suicide
- new or worse depression
- new or worse anxiety
- feeling very agitated or restless
- panic attacks
- trouble sleeping (insomnia)
- new or worse irritability
- acting aggressive, being angry, or violent
- acting on dangerous impulses
- an extreme increase in activity and talking (mania)
- other unusual changes in behavior or mood
What else do I need to know about antidepressant medicines?
- Never stop an antidepressant medicine without first talking to a healthcare provider. Stopping an antidepressant medicine suddenly can cause other symptoms.
- Antidepressants are medicines used to treat depression and other illnesses. It is important to discuss all the risks of treating depression and also the risks of not treating it. Patients should discuss all treatment choices with the healthcare provider, not just the use of antidepressants.
- Antidepressant medicines have other side effects. Talk to the healthcare provider about the side effects of this medicine.
- Antidepressant medicines can interact with other medicines. Know all of the medicines that you take. Keep a list of all medicines to show the healthcare provider. Do not start new medicines without first checking with your healthcare provider.
- Not all antidepressant medicines prescribed for children are FDA approved for use in children. Talk to your child's healthcare provider for more information.
What is KHEDEZLA?
- KHEDEZLA is a prescription medicine used to treat depression. KHEDEZLA belongs to a class of medicines known as SNRIs (or serotonin-norepinephrine reuptake inhibitors).
It is not known if KHEDEZLA is safe and effective for use in children.
Who should not take KHEDEZLA?
Do not take KHEDEZLA if you:
- are allergic to desvenlafaxine, venlafaxine or any of the ingredients in KHEDEZLA. See the end of this Medication Guide for a complete list of ingredients in KHEDEZLA.
- take a monoamine oxidase inhibitor (MAOI). Ask your healthcare provider or pharmacist if you are not sure if you take an MAOI, including the antibiotic linezolid and the intravenous medicine methylene blue.

Rare, but potentially life-threatening conditions called serotonin syndrome can happen when medicines such as KHEDEZLA are taken with certain other medicines. Serotonin syndrome can cause serious changes in how your brain, muscles, heart and blood vessels, and digestive system work. Especially tell your healthcare provider if you take the following:
- medicines to treat migraine headaches known as triptans
- medicines used to treat mood, anxiety, psychotic, or thought disorders, including tricyclics, lithium, selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), or other dopamine antagonists, such as metoclopramide
- St. John's Wort
- MAOIs (including linezolid, an antibiotic and intravenous methylene blue)
- tryptophan supplements
Ask your healthcare provider if you are not sure if you are taking any of these medicines.
Before you take KHEDEZLA with any of these medicines, talk to your healthcare provider about serotonin syndrome. See “What are the possible side effects of KHEDEZLA?”
Do not take KHEDEZLA with other medicines containing venlafaxine or desvenlafaxine.
How should I take KHEDEZLA?
- Take KHEDEZLA exactly as your healthcare provider has told you.
- Take KHEDEZLA at about the same time each day.
- KHEDEZLA may be taken either with or without food.
- Swallow KHEDEZLA tablets whole, with fluid. Do not crush, cut, chew, or dissolve KHEDEZLA tablets because the tablets are time-released.
- When you take KHEDEZLA, you may see something in your stool that looks like a tablet. This is the empty shell from the tablet after the medicine has been absorbed by your body.
- It is common for antidepressant medicines such as KHEDEZLA to take several weeks before you start to feel better. Do not stop taking KHEDEZLA if you do not feel results right away.
- Do not stop taking or change the dose of KHEDEZLA without talking with your healthcare provider, even if you feel better.
- Talk with your healthcare provider about how long you should use KHEDEZLA. Take KHEDEZLA for as long as your healthcare provider tells you to.
- If you miss a dose of KHEDEZLA, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose. Do not try to “make up” for the missed dose by taking two doses at the same time.
- Do not take more KHEDEZLA than prescribed by your healthcare provider. If you take more KHEDEZLA than the amount prescribed, contact your healthcare provider right away.
- If you take too much KHEDEZLA, call the Poison Control Center at 1-800-222-1222 or go to the nearest hospital emergency room right away.
Switching from other antidepressants
Side effects from discontinuing antidepressant medication have occurred when patients switched from other antidepressants, including venlafaxine, to desvenlafaxine. Your doctor may gradually reduce the dose of your initial antidepressant medication to help to reduce these side effects.

What are the possible side effects of KHEDEZLA?

KHEDEZLA may also cause other serious side effects, including:
- New or worsened high blood pressure (hypertension). Your healthcare provider should monitor your blood pressure before and while you are taking KHEDEZLA. If you have high blood pressure, it should be controlled before you start taking KHEDEZLA.
- Abnormal bleeding or bruising. KHEDEZLA and other SNRIs/SSRIs may cause you to have an increased chance of bleeding. Taking aspirin, NSAIDs (non-steroidal anti-inflammatory drugs), or blood thinners may add to this risk. Tell your healthcare provider right away about any unusual bleeding or bruising.
- Visual Problems
- Eye Pain
- Changes in vision
- Swelling or redness in or
around the eye
Only some people are at risk for these problems. You may want to undergo an eye examination to see if you are at risk and receive preventative treatment if you are.
- Symptoms when stopping
KHEDEZLA (discontinuation symptoms). Side effects may occur when stopping KHEDEZLA
(discontinuation symptoms), especially when therapy is stopped suddenly. Your
healthcare provider may want to decrease your dose slowly to help avoid side
effects. Some of these side effects may include:
- sleeping problems (insomnia)
- abnormal dreams
- Seizures (convulsions)
- Low sodium levels in your blood. Symptoms of this may include: headache, difficulty concentrating, memory changes, confusion, weakness and unsteadiness on your feet. In severe or more sudden cases, symptoms can include: hallucinations (seeing or hearing things that are not real), fainting, seizures and coma. If not treated, severe low sodium levels could be fatal.
- Lung problems. Some people who have taken the medicine venlafaxine which is the same kind of medicine as the medicine in KHEDEZLA have had lung problems. Symptoms of lung problems include difficulty breathing, cough, or chest discomfort. Tell your healthcare provider right away if you have any of these symptoms.
Common side effects with KHEDEZLA include:
- loss of appetite
- decreased sex drive
- delayed orgasm and ejaculation
