Trazodone weight gain (A complete guide)

In this blog, we will discuss Trazodone weight gain, the most common uses of Trazonde, side effects, precautions, potential interactions with other drugs and substances.

Trazodone weight gain: gaining weight?

A possible side effect of Trazodone is weight gain but it can also make you lose weight due to loss of appetite.

If you are already using Trazodone and have noticed changes in your weight, it is important to share this information with your doctor and let him/her know your concerns. 

According to the NHS, trazodone can make you feel more or less hungry than usual consequently making you gain or lose weight when you start the treatment. 

This is backed up by science but some conflicting results regarding weight gain have arisen.

A study from 2007 suggests that antidepressants can cause clinically significant weight gain when compared to some second-generation antipsychotics (SGAs), indicating that SGAs on average may cause 2.3 kg a month weight gain during the first 12 weeks of treatment while antidepressants can cause 3 kg weight gain in 6 weeks. 

What is Trazodone?

Trazodone is considered an antidepressant drug that belongs to the group of Serotonin Reuptake Inhibitors or SSRIs.

It is used frequently as a treatment for depression. 

This drug was developed in Italy in the 1960s as antidepressant medication.

Initially, due to the side effects, this antidepressant wasn’t widely accepted in the medical community, however, it became recognized by many internists and clinicians because of the potential benefits of the drug, especially when administered at low doses.

Under the name trazodone (generic) in 1981, it was approved by the U.S Food and Drug Administration (FDA) under the brand name Desyrel.

Today, it is prescribed under the brand name Olepro to treat sleep disorders such as insomnia as well as anxiety disorder and unibipolar depression.

Does trazodone cause sleepiness?

For many people, this drug has a sedative effect that causes a relaxing effect and can make you feel very sleepy.

In prescribing the drug for sleep disorders, physicians typically recommend taking a low dose at bedtime in order to limit the effects of drowsiness.

Still, some people report lingering effects, including sluggishness and feeling drained or low energy, particularly upon waking.

How does Trazodone work?

Trazodone is meant to restore the depleted chemicals in the brain (neurotransmitters).

One of the most important neurotransmitters is serotonin which when balanced, improves your mood, appetite, memory, sexual function and desire, energy levels, decreases anxiety and insomnia related to depression.

Researchers have found that depression is caused by an imbalance among the neurotransmitters acetylcholine, norepinephrine, dopamine, and serotonin.

It is believed that trazodone affects the brain’s neurotransmitters by inhibiting the uptake of serotonin by nerves and consequently, the increase of this neurotransmitter end up stimulating other nerves.

How quickly does it work?

Some people who use this drug for sleep disorders have indicated that they get to experience the sedative effect within 30 mins after the intake, but remember that every person can react differently to the drug.

People who take it as an antidepressant may start noticing benefits after 1 or 2 weeks of consistently taking the medicine, and it may even take up to 4 weeks to experience the full benefits and desired results.
