Trazodone belongs to a class of medications called serotonin modulators, which means they work by altering the activity of post-synaptic serotonin receptors and by inhibiting the reuptake of serotonin.

While trazodone is not considered a highly addictive prescription medication, it still has a potential for misuse and dependence.

Individuals who abuse trazodone or who are prescribed it should be aware of its effects and seek professional advice.

Is Trazodone Addictive For People?

Trazodone is not considered highly addictive, yet there is still potential for misuse and dependence.

A study done by Psychopharmacology discussed the abuse potential for three different drugs, including trazodone, Ambien, and Halcion.

Findings suggest that trazodone is less addictive than the other two drugs in the study, yet it is still misused and can cause physical dependence, especially when used for a long period.

According to Substance Abuse and Rehabilitation, most cases of antidepressant abuse occur in individuals with other substance use and mood disorders.

What Class Of Drug Is Trazodone?

Trazodone is a serotonin modulator, or in the serotonin-antagonist-and-reuptake-inhibitor (SARI) class of medications.

Serotonin is a neurotransmitter that plays an important function in mood stabilization. When a person’s serotonin levels are low, it can contribute to depression and other mental health disorders.

Serotonin modulators, like trazodone, work by targeting certain serotonin receptors, including the 5-HT2A receptor.

How Does Trazodone Make You Feel?

Most people who have been prescribed trazodone report feelings of relaxation and sleepiness.

It can also help people improve their mood and manage the symptoms of depression.

Some people may abuse trazodone for its sedative effects and to achieve a “high.” While it may not produce a sense of euphoria similar to other drugs like marijuana, it can make a person feel extremely relaxed and drowsy, and some people find pleasure in it.

Additionally, when first taking trazodone, a person may feel that their symptoms of depression or anxiety are worsening.

This can be because the body is adjusting to new chemical levels and changes. However, it is important to let your doctor know if you are experiencing adverse side effects.

Trazodone is not known to be habit-forming. However, it should only be taken as prescribed to avoid misuse and potentially dangerous adverse effects.

However, if a person is misusing trazodone, taking it every night can be extremely harmful, increase the risk of overdose, and have serious negative effects on their physical and mental health.

How Long Does It Take For Trazodone To Work?

It can take a couple of weeks for trazodone to start to work and for a person to see improvements.

How Often Should You Take Trazodone?

Trazodone is usually taken as a single dose per day.

Sometimes, a doctor may recommend a person split it in half and take it twice a day.

Is 50mg Of Trazodone A Lot?

50 mg of trazodone is not considered a lot; it is usually the starting dose.

Trazodone is available in 25 mg, 50 mg, 100 mg, and 300 mg oral tablets.

However, taking any dose of a medication when it is not prescribed can be very dangerous and result in harm to both the brain and body.

Can Trazodone Be Mixed With Alcohol?

Alcohol can worsen the effects of trazodone, and mixing the two can become dangerous.

Mixing alcohol with antidepressants like trazodone can not only make a person extremely drowsy but also make a person feel more depressed or anxious.

Individuals who misuse trazodone often do so by combining it with other substances. Mixing substances like trazodone and alcohol can increase a person’s risk of overdose and result in serious consequences.

Are There Interactions Between Lexapro And Trazodone?

Lexapro, or escitalopram, is another antidepressant medication used to treat depression and generalized anxiety disorder.

Taking escitalopram together with trazodone is usually not advised as it may cause adverse side effects and put a person at higher risk of serotonin syndrome.

It is important to let your doctor know if you are already taking Lexapro or any other antidepressants so that you can reduce the risk of negative and potentially dangerous side effects.

What Should You Not Take With Trazodone?

It is important to let your doctor know of any prescription medications and non-prescription medications you are taking, including vitamins and herbal supplements, before starting trazodone.

You should let your healthcare provider know if you are taking monoamine oxidase inhibitors (MAOIs) like tranylcypromine or isocarboxazid, as your doctor may typically recommend not taking the medications together.
