Trazodone vs. Zoloft—Which Drug To Choose for Sleep?

Trazodone vs. Zoloft—Which Drug To Choose for Sleep?

When the night comes, we all hope to catch some sleep and get reenergized for the next day. For approximately 50–70 million adults in the U.S., this isn’t as easy as it sounds.

If you’re in the same situation, you might have tried different methods, from meditation to taking breaks from the screen, with limited success. The best approach is to see a sleep medicine specialist who can recommend effective medications like trazodone and Zoloft.

This trazodone vs. Zoloft comparison will give you a clearer picture of how these drugs work and where to get them.

Zoloft vs. Trazodone—A Concise Overview

Trazodone and Zoloft (sertraline) are both antidepressants—a class of drugs used to alleviate the symptoms of depression and other mood disorders. While they have similar mechanisms of action, these medications have different applications.

Trazodone is sold under various brand names and is primarily prescribed to patients with:

  1. Major depressive disorders
  2. Anxiety disorders
  3. A combination of depressive and anxiety disorders

It’s also used off-label in the short-term treatment of insomnia.

Trazodone works by inhibiting serotonin reuptake by the nerves in the brain, increasing this neurotransmitter’s levels in the nerve synapse. While it’s not a selective serotonin reuptake inhibitor (SSRIs), the drug shares striking similarities with this group of medicines.

Zoloft is a selective serotonin reuptake inhibitor (SSRI) typically prescribed to patients with:

  • Depression
  • Panic disorder
  • Social anxiety disorder
  • Obsessive-compulsive disorder (OCD)
  • Post-traumatic stress disorder (PTSD)
  • Premenstrual dysphoric disorder (PMDD)

The drug blocks the reabsorption of serotonin in the brain, keeping the neurotransmitter in the synaptic gap for an extended period. 

In both cases, the increased serotonin levels in the nerve synapse produce a calming effect while promoting melatonin production and inducing sleep. According to the DEA, trazodone and Zoloft aren’t controlled substances, but you can only get these drugs with your doctor’s prescription.

Trazodone vs. Zoloft for Sleep—Dosage Guidelines

Trazodone comes in tablet, capsule, or liquid forms and is available in six doses:

  1. 10 mg
  2. 20 mg
  3. 50 mg
  4. 100 mg
  5. 150 mg
  6. 300 mg

The average starting dose for adults with sleeplessness is 25 mg in tablet form, which may increase depending on your medical history and sleep problems. 

Zoloft comes in four doses:

  1. 20 mg—oral solution
  2. 25 mg
  3. 50 mg
  4. 100 mg

The typical dose for sleeplessness is 50 mg, taken in the evening. Healthcare providers usually prescribe lower doses for patients over 65 or individuals with specific health conditions.

These are average values—your doctor will assess your health status before deciding on the appropriate dose and time to take these medications.

Zoloft and Trazodone—Duration of Effects

Trazodone’s sedative effects typically kick in within 30 minutes. This drug reaches peak concentration within 1–2 hours, and the effects last for about 5–7 hours. 

Zoloft is slow-acting, with peak concentration occurring at 4.5–8 hours

When taking these drugs, you should allocate at least seven hours to sleep. You should also avoid activities that require sharp focus, like driving or operating heavy machinery, for at least one hour after waking up. If you experience persistent fatigue or drowsiness the next day, inform your healthcare provider.

Trazodone Versus Zoloft—Which One Offers Better Sleep?

Both trazodone and Zoloft can be effective for sleep, but none of these is a one-size-fits-all solution. The most effective drug for sleep depends on numerous factors, including your lifestyle, medical history, and the type of insomnia you have. 

Before choosing between these drugs, you should consult a sleep expert who can design a comprehensive treatment plan. The biggest problem is that getting an appointment with a sleep specialist can be challenging due to their limited availability in the U.S.
