What Do Antidepressants Do?

Antidepressants are a class of medications used to treat a variety of mental and emotional conditions, including depression, anxiety, and post-traumatic stress. They work by altering the chemistry of the brain, affecting the hormones and chemicals that are responsible for regulating emotions and mood. By doing so, antidepressants can improve mood and reduce the symptoms of depression.

Types of Antidepressants

There are several different types of antidepressants that work in different ways. Some of the most commonly prescribed antidepressants include:

• • Selective serotonin reuptake inhibitors (SSRIs): SSRIs are the most commonly prescribed type of antidepressant. They work by increasing the levels of the chemical serotonin, which helps regulate mood. Examples include fluoxetine, sertraline, and paroxetine.

 

• • Serotonin-norepinephrine reuptake inhibitors (SNRIs): These medications work by increasing the levels of two different chemicals in the brain: serotonin and norepinephrine. They are typically used to treat more severe forms of depression. Examples include duloxetine and venlafaxine.

 

• • Tricyclic antidepressants (TCAs): TCAs work by increasing levels of three different chemicals in the brain: serotonin, norepinephrine, and dopamine. They are most often used to treat more severe forms of depression, but they can also have side effects. Examples include amitriptyline and nortriptyline.

 

• • Monoamine oxidase inhibitors (MAOIs): MAOIs work by blocking the enzyme monoamine oxidase, which helps regulate the levels of several different chemicals in the brain. These medications can be effective, but they also come with more potential side effects than other types of antidepressants. Examples include phenelzine and tranylcypromine.

 

How Do Antidepressants Work?

Antidepressants work by influencing the levels of certain chemicals in the brain that are associated with mood. For example, SSRIs increase the level of serotonin. This can help balance the levels of serotonin in the brain, which can improve mood and reduce symptoms of depression.

Other antidepressants work by affecting the levels of other chemicals, such as norepinephrine and dopamine. These chemicals are known to be important for regulating emotions, energy levels, and overall mental well-being.

How Long until Antidepressants Take Effect?

The timeline for when antidepressants take effect can vary. It usually takes several weeks before they start working, as it takes time for the brain to adjust to the new levels of chemicals. It’s important to not give up in the first few weeks if no effects are noticed – it can take time for antidepressants to reach their full potential.

Are There Side Effects of Antidepressants?

Like all medications, antidepressants come with potential side effects. The most common side effects include:

• • Nausea

 

• • Headaches

 

• • Insomnia

 

• • Drowsiness

 

• • Weight gain

 

• • Loss of libido

 

• • Low blood pressure

 

• • Sexual difficulties

 

• • Dry mouth

 

• • Diarrhea

 

Most of these side effects can be managed by talking to a doctor. In some cases, switching to a different type or dosage of antidepressant can help reduce the side effects.
