Antidepressants are among the most commonly prescribed medications, with an estimated 29 million people in the U.S. taking them including about 18 million who have been on them for at least five years (Elgaddal et al, 2025, Davies et al, 2019). Discontinuing antidepressants is associated with withdrawal reactions, which are often under-recognized and poorly treated (Shapiro et al, 2025a).
As a psychiatrist who specializes in prescribing medications, patients frequently ask if they will ever be able to stop their antidepressants. Some have had negative experiences and felt quite ill when previously tapering off antidepressants. Others read online that antidepressants can be extremely difficult to discontinue. The fear of a withdrawal reaction is justifiable.
The good news is that individuals can safely taper off antidepressants. They do not need to remain on these medications indefinitely in order to avoid a withdrawal reaction. Nor do they need to suffer through debilitating withdrawal symptoms. There are widely accepted strategies to taper off antidepressants smoothly with minimal disruption to normal functioning.
What is antidepressant withdrawal syndrome?
Antidepressant withdrawal syndrome can occur after selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs) are stopped abruptly or tapered too quickly. It is more likely to occur after being on medication for at least several months. Physical symptoms may include dizziness, nausea, insomnia, headaches, muscle soreness or in extreme cases electric shock-like sensations (Davies et al, 2019). Cognitive symptoms may include feeling irritable, anxious, agitated, hopeless, and in despair (Davies et al, 2019). Often these symptoms are transient, lasting several days but occasionally linger for weeks. Some patients report severe symptoms lasting for months, causing significant impairment in normal functioning (Davies et al, 2019).
Withdrawal reactions typically begin within hours to days of decreasing the medication and do not represent a recurrence of the underlying depression. A literature review of 24 studies, published in 2019, found that on average 56% of individuals who tried to discontinue antidepressants experienced withdrawal symptoms and 46% of them describe the withdrawal effects as severe. The authors noted that the withdrawal reactions often lasted for several weeks or months (Davies, et al, 2019).
Strategies to prevent antidepressant withdrawal
The antidepressant fluoxetine (Prozac) is less likely than others to cause a withdrawal reaction, largely due to the long elimination half-life of about 22 days of its active component (Shapiro et al, 2025). Medications with short elimination half-lives of about 0.4-1.1 days such as sertraline (Zoloft), duloxetine (Cymbalta), escitalopram (Lexapro), paroxetine (Paxil), and venlafaxine (Effexor) are associated with a higher likelihood of withdrawal reactions (Shapiro et al, 2025b). Here are guidelines that can mitigate withdrawal symptoms and enable the safe discontinuation of antidepressant medications.
Taper slowly
A gradual decrease in dosage over the course of several months is usually well-tolerated without causing disruptions to individuals’ routines and well-being. A slow taper also allows for the monitoring for any signs of a relapse; if this were to occur the dosage can be increased to prevent a full-blown episode. Patients often tolerate a faster taper at higher doses but need to adjust dosages more slowly as they approach complete discontinuation. At lower doses the same milligram decrease represents a greater percentage decrease in the total dosage. For example, lowering sertraline from 200 mg to 150 mg is a 25% decrease but lowering it from 100 mg to 50 mg is a 50% decrease and from 50 mg to 0 mg is a 100% decrease. Withdrawal reactions tend to be more likely at the end of the taper when patients are almost off the medication.
Liquid version or custom dose pills
Sometimes patients do not tolerate a slow taper using the pill dosages that are available and need to taper even more gradually. In these situations it is reasonable to switch the medication to a liquid formulation. Another option is a custom-made dosage which is referred to as compounded and can be made at certain pharmacies.
Prozac substitution
If an individual still experiences withdrawal symptoms, another strategy involving the transient addition of the long-acting antidepressant fluoxetine can be implemented. The patient would titrate to the therapeutic dose of fluoxetine while still taking the original antidepressant. After about two weeks, the original antidepressant can be tapered since the fluoxetine acts in a similar enough way as to block withdrawal effects. Afterwards, the fluoxetine can be tapered fairly easily.
Patient education
It is essential to educate patients about withdrawal reactions in advance of tapering off their antidepressants. If withdrawal symptoms are mild and manageable, they can continue the current dose and wait for symptoms to fully resolve. They should wait an additional week after complete resolution of withdrawal symptoms before decreasing the dose again. If the dose is decreased while withdrawal symptoms are still present, even mildly, there is a good chance the symptoms will worsen. This can necessitate having to increase the dose again to allow the symptoms to abate. It is better to be proactive than engage in a cycle of chasing the withdrawal and starting over again.
Guidelines are not set in stone
This is a framework with estimates of timing and guidance. However individual responses vary and the taper process should be done in coordination with the patient’s prescribing doctor. There also may be other factors that influence the urgency of stopping the medications such as pregnancy or medication interactions. Patients should not have to remain on antidepressants when they are no longer needed. That can lead to unnecessary treatments and potential side effects.
