Are SSRIs Addictive?

Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed to manage depressive and anxiety disorders. Seen as one of the most important breakthroughs in psychiatric medicine, these medications are effective and better tolerated than older antidepressants. Still, it’s normal to have concerns around SSRIs and addiction, as well as long-term safety.1

If you’re wondering if you become addicted to SSRIs, read more below or contact our Kansas City rehab center if you’re struggling with addiction or a co-occurring disorder.

What Are SSRIs?

SSRIs are antidepressants that appeared in the late 20th century. Developed as safer alternatives to previous medications, like monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants (TCAs), these medications marked a turn in psychopharmacology.1

SSRIs are typically prescribed to treat depression, anxiety, post-traumatic stress disorder (PTSD), and other anxiety conditions.1,2 These medications are widely available in tablet and capsule forms.2 They are also available in liquid solutions for those who struggle to swallow pills.2 SSRIs are marketed under various brand and generic drug names.3 Here are some common ones3:

• Celexa (citalopram)
• Lexapro (escitalopram)
• Prozac (fluoxetine)
• Luvox & Luvox CR (fluvoxamine)
• Paxil & Paxil CR (paroxetine)
• Zoloft (sertraline)
• Viibryd (vilazodone)

How Do SSRIs Work?

SSRIs stop serotonin from being reabsorbed by blocking the serotonin transporter (SERT).1 Serotonin is a neurotransmitter involved in regulating mood, sleep, appetite, memory, and other important functions.4 SSRIs were developed based on the link between depression and low serotonin levels.1

Normally, your brain releases serotonin into the synapse (the space between brain cells), where it attaches to receptors to send signals. SSRIs increase serotonin levels in the brain by blocking the reabsorption of serotonin through the SERT. This allows more serotonin to remain available in the brain, regulating mood and anxiety. This process varies by the specific SSRI, but these medications generally work similarly.1

Are SSRIs Addictive?

No, SSRIs are not considered addictive.5 These medications aren’t even classified under the Controlled Substances Act because of their low risk for abuse and dependence.6,7 Antidepressants, such as SSRIs, also aren’t listed within the 10 substance classes within the DSM-5 criteria for addiction.5 This is because they don’t produce compulsive drug-seeking behavior, which is fundamental in the disease model of addiction.5

Most addictive drugs increase dopamine levels in the brain’s reward system, often causing a surge that reinforces drug use.8 SSRIs work to balance serotonin levels and don’t activate dopamine reward pathways that contribute to addiction.1 While SSRIs and other antidepressants aren’t known to be addictive, they’ve been associated with withdrawal-like symptoms.1

Can I Quit My SSRI “Cold Turkey”?

No, it’s not recommended to quit an SSRI cold turkey.9 Although SSRIs are not considered addictive and do not produce compulsive drug-seeking behavior, abrupt discontinuation can cause discontinuation syndrome.1,5,9

So, can you become dependent on SSRIs? The short answer is yes. Discontinuation syndrome is a condition that produces symptoms that resemble withdrawal when stopping, reducing, or missing doses of antidepressants, including SSRIs.9 Paroxetine consistently ranks among the forms with the highest discontinuation risks, while fluoxetine carries the lowest.1

Some emerging evidence suggests that quitting SSRIs cold turkey can elicit persistent adverse effects.1 In rare cases, certain discontinuation symptoms may persist for months or longer after stopping treatment.1 Because of this, it’s recommended to work with your provider to develop a plan to taper off SSRIs.9

Here are some discontinuation syndrome effects9:

• Flu-like symptoms (lethargy, fatigue, headache, achiness, sweating)
• Insomnia (with vivid dreams or nightmares)
• Nausea (sometimes vomiting)
• Imbalance (dizziness, vertigo, light-headedness)
• Sensory disturbances (“burning,” “tingling,” “electric-like,” or “shock-like” sensations)
• Hyperarousal (anxiety, irritability, agitation, aggression, mania, jerkiness)

SSRIs & Mental Health/Substance Use Disorders

SSRIs are considered a first-line treatment for managing depression, anxiety, and other mood disorders.1 People often struggle with substance use disorder (SUD) and mental health conditions at the same time.10 Experts recommend treating co-occurring disorders with an integrated approach to promote lasting recovery.10 This may include a blend of behavioral therapies, medications, and other recovery support services.10

SSRIs are generally safe and well-tolerated in people battling drug or alcohol addiction and co-occurring disorders.10,11 Although these medications are safe during treatment, it’s crucial to consider unsafe drug combinations, especially if you relapse while taking an SSRI.1,11 If you do relapse, be sure to work with your treatment provider to get back on track in recovery safely.

Common SSRI Drug Interactions

While SSRIs have a lower risk of interaction with alcohol or other drugs when compared to other antidepressants, you should not mix certain common substances with these medications.1,10 Mixing SSRIs with certain medications or substances can increase side effects, alter drug levels, or reduce the effectiveness of one or both medications.1 Furthermore, using SSRIs with these drugs can produce adverse effects and health risks, including an increased risk of bleeding, heart effects, serotonin syndrome, and overdose.1,2

Here are some substances you shouldn’t mix with SSRIs:

• Anticoagulants such as warfarin1
• Antiplatelet agents like aspirin1
• Nonsteroidal anti-inflammatory drugs (NSAIDs)1
• Tamoxifen1
• Opioids1
• Metoprolol1
• Theophylline1
• Caffeine (particularly with fluvoxamine)1
• Diazepam (certain SSRIs)1
• QTc-prolonging drugs, including antipsychotics1
• Serotonergic drugs, including tricyclic antidepressants, lithium, tramadol, and methadone2
• Monoamine oxidase inhibitors (MAOIs)2

An exact list of unsafe substances and interaction severity will vary depending on the specific SSRI.1 Always consult with your doctor if you’re worried about unsafe interactions with other drugs or supplements you may be taking. Drinking alcohol while taking an SSRI is also not recommended.2
