Antidepressant Detox: Withdrawal Symptoms And Timeline

Medically Reviewed by Johnelle Smith, M.D. on October 11, 2021

Stopping an antidepressant medication very suddenly may cause what’s known as discontinuation syndrome or withdrawal syndrome. Detox for antidepressant withdrawal may be recommended for people at risk of serious effects of withdrawal.

How To Detox From Antidepressants

Many prescription drugs that are used to treat depression, anxiety, and other mental health disorders can be habit-forming and result in physical dependence.

Physical dependence on a drug can result in what’s known as discontinuation syndrome, or withdrawal, if a person tries to stop taking a drug too quickly or all at once.

Which Antidepressants Require Detox?

A variety of medications, including tricyclic antidepressants and selective serotonin reuptake inhibitors (SSRIs), can cause physical dependence and withdrawal with chronic use. Taking antidepressants for long periods of time can also lead to an increased tolerance to antidepressants.

Common antidepressants that may require detox include:

This is not a comprehensive list. If you’ve been taking medication for depression or anxiety for some time, talk to your doctor about whether developing a detox plan is necessary for you.

Who Needs To Detox From Antidepressants?

Detoxification, also known as detox, may be necessary for anyone who’s taken a habit-forming antidepressant medication regularly for at least several weeks.

Taking an SSRI medication or other type of antidepressant can cause physical dependence in a short period of time, which can lead to withdrawal with stopped use.

Signs of physical dependence include:

  • needing to increase your dose over time
  • feeling anxious or “off” if you miss a dose
  • feeling physically sick if you miss a dose

Dependence is not the same as drug addiction, although the two can co-occur. People can be physically dependent on a drug without having a drug use disorder, or addiction.

Signs And Symptoms Of Antidepressant Withdrawal

What withdrawal feels and looks like can vary depending on the type of antidepressant you’re taking, as well as factors such as the dosage and your overall health.

Early signs of antidepressant withdrawal can begin to set in within one to two days after your last dose and may last for anywhere from five days to several weeks.

Symptoms of antidepressant withdrawal can include:

  • headache
  • nausea
  • depression
  • anxiety
  • fatigue
  • sweating
  • dizziness
  • confusion
  • diarrhea
  • muscle aches
  • impaired balance
  • ringing in the ears
  • mood swings
  • numbness or tingling sensations
  • seizures

Withdrawal symptoms generally last longer and are more likely to be severe for those who have severe drug dependence or suddenly stop taking a very high dose all at once.

How Long Does Antidepressant Withdrawal Last?

On average, withdrawal from SSRI antidepressants lasts about five days. For some, antidepressant withdrawal (including but not limited to SSRIs) can last several weeks.

Factors that can affect how long withdrawal lasts include:

  • type of antidepressant
  • drug half-life
  • dose taken
  • frequency of use (e.g. once a day)
  • overall health
  • use of other drugs
  • severity of dependence

Antidepressant Detox And Withdrawal Timeline

Tapering off an antidepressant medication, also known as weaning, is generally the preferred method for detoxification. During this process, withdrawal symptoms can still develop.

First Three Days Of Withdrawal

Quitting an antidepressant all at once could cause a reaction within as little as a few hours, or within the first 48 to 72 hours after last use.

At this time, some physical and psychological symptoms—including changes in mood, and flu-like symptoms—may arise.

First Week Of Withdrawal

Withdrawal symptoms will often peak within the first week of stopping or beginning the weaning (tapering) process. The intensity of symptoms during this time may ebb and flow.

Antidepressant withdrawal typically resolves within one to two weeks of taking your last dose, although some may notice lingering symptoms.

For instance, withdrawal symptoms may last longer for people who:

  • are detoxing from multiple drugs
  • are detoxing from a drug with a long half-life
  • have taken an antidepressant for years
  • are weaning off of a high dose

Are There Risks To Antidepressant Detox?

Weaning off an antidepressant or stopping your drug use suddenly after taking it for some time can pose certain risks.

Potential risks of detox include:

  • rebound anxiety
  • depression
  • insomnia
  • seizures
  • psychosis
  • catatonia

The best way to prevent dangers associated with antidepressant withdrawal is to consult a doctor about how to safely get off an antidepressant medication.

Consulting a doctor, or getting in touch with a detox professional, can allow you to create a plan for slowly weaning off the medication. This can help prevent severe withdrawal symptoms.
