List of Antidepressants That Cause Hair Loss (Alopecia)

What are antidepressants?

Depression is a mental health issue that starts most often in early adulthood. It’s also more common in women. However, anyone at any age may deal with depression.

Depression affects your brain, so drugs that work in your brain may prove beneficial. Common antidepressants may help ease your symptoms, but there are many other options as well.

Each drug used to treat depression works by balancing certain chemicals in your brain called neurotransmitters. These drugs work in slightly different ways to ease your depression symptoms.

Many common drugs for depression fall into the following drug classes:

•          selective serotonin reuptake inhibitors (SSRIs)

•          serotonin-norepinephrine reuptake inhibitors (SNRIs)

•          tricyclic antidepressants (TCAs)

•          tetracyclic antidepressants

•          dopamine reuptake blockers

•          5-HT1A receptor antagonists

•          5-HT2 receptor antagonists

•          5-HT3 receptor antagonists

•          monoamine oxidase inhibitors (MAOIs)

•          noradrenergic antagonists

Atypical antidepressants, which don’t fall into these drug classes, and natural supplements, such as St. John’s wort, are also available.

What is hair loss?

According to the NIH, alopecia areata is a disease that happens when the immune system attacks hair follicles and causes hair loss. Hair follicles are the structures in the skin that form hair. While hair can be lost from any part of the body, alopecia areata usually affects the head and face. Hair typically falls out in small, round patches about the size of a quarter, but in some cases, hair loss is more extensive. Most people with the disease are healthy and have no other symptoms.

The course of alopecia areata varies from person to person. Some have bouts of hair loss throughout their lives, while others only have one episode. Recovery is unpredictable too, with hair regrowing fully in some people but not in others.

There is no cure for alopecia areata, but there are treatments that help hair grow back more quickly. There are also resources to help people cope with hair loss.

Who Gets Alopecia Areata?

Anyone can have alopecia areata. Men and women get it equally, and it affects all racial and ethnic groups. The onset can be at any age, but most people get it in their teens, twenties, or thirties. When it occurs in children younger than age 10, it tends to be more extensive and progressive.

If you have a close family member with the disease, you may have a higher risk of getting it, but for many people, there is no family history. Scientists have linked a number of genes to the disease, which suggests that genetics play a role in alopecia areata. Many of the genes they have found are important for the functioning of the immune system.

People with certain autoimmune diseases, such as psoriasis, thyroid disease, or vitiligo, are more likely to get alopecia areata, as are those with allergic conditions such as hay fever.

It is possible that emotional stress or an illness can bring on alopecia areata in people who are at risk, but in most cases, there is no obvious trigger. Hair loss can be a side effect of certain drugs, such as those used for cancer, arthritis, depression, heart problems, gout, and high blood pressure.

Types of Alopecia Areata

There are three main types of alopecia areata:

•          Patchy alopecia areata. In this type, which is the most common, hair loss happens in one or more coin-sized patches on the scalp or other parts of the body.

•          Alopecia totalis. People with this type lose all or nearly all of the hair on their scalp.

•          Alopecia universalis. In this type, which is rare, there is a complete or nearly complete loss of hair on the scalp, face, and rest of the body.

How medications cause hair loss

Drugs cause hair loss by interfering with the normal cycle of scalp hair growth.  Medications and supplements for depression can cause two types of hair loss: anagen effluvium and telogen effluvium. Anagen effluvium is the loss of actively growing hair during the growth stage of the hair cycle. It affects not only the hair on your head but can also impact eyebrows, eyelashes, and body hair as well.

Telogen effluvium occurs when hair follicles are in the resting phase, causing hair to fall out early. Telogen effluvium is more common than anagen effluvium and can develop as a possible side effect of many widely used medications and supplements. While many antidepressants are labeled with hair loss as a potential side effect, with the exception of chemotherapy treatment, it’s quite rare with most of those medications

List of antidepressants that cause hair loss

Several antidepressants can cause hair loss, they include:

  • Anafranil (clomipramine): Clomipramine, sold under the brand name Anafranil among others, is a tricyclic antidepressant. It is used for the treatment of an obsessive-compulsive disorder, panic disorder, major depressive disorder, and chronic pain. Anafranil can be ‘toxic’ to the hair follicles and this can alter the hair growth cycle, which over time can lead to abnormal growth.
  • Janimine (imipramine): Imipramine, sold under the brand name Janimine, Tofranil, among others, is a tricyclic antidepressant mainly used in the treatment of depression. It is also effective in treating anxiety and panic disorder. The drug is also used to treat bedwetting. Tricyclic antidepressants, like Janimine (imipramine) and virtually all the new generation of antidepressants may on rare occasions lead to alopecia.
  • Paxil (paroxetine): Paroxetine, sold under the brand names Paxil and Seroxat among others, is an antidepressant of the selective serotonin reuptake inhibitor class. Some people who take Paxil (paroxetine) for depression and mood stabilization have reported hair loss as a side effect.
  • Prozac (fluoxetine hydrochloride): Fluoxetine, sold under the brand names Prozac and Sarafem among others, is an antidepressant of the selective serotonin reuptake inhibitor class. It is used for the treatment of major depressive disorder, obsessive-compulsive disorder, bulimia nervosa, panic disorder, and premenstrual dysphoric disorder. The SSRIs like fluoxetine, have been reported to cause hair loss in a very small minority of patients.
  • Sertraline (Zoloft): Sertraline, sold under the brand name Zoloft among others, is an antidepressant of the selective serotonin reuptake inhibitor class. The efficacy of sertraline for depression is similar to that of other antidepressants, and the differences are mostly confined to side effects.  Hair loss is a side effect that some people report while taking a sertraline treatment. This may show up as bald patches or overall hair thinning. Sertraline (Zoloft)-related hair loss is not common, but it can happen.
  • Bupropion (Wellbutrin and Zyban): Bupropion, sold under the brand names Wellbutrin and Zyban among others, is an atypical antidepressant primarily used to treat the major depressive disorder and to support smoking cessation. The results from studies indicate that the risk of hair loss is higher with bupropion compared with other antidepressants. Specifically, the risk of bupropion was higher compared with the six SSRIs and three SNRIs. Compared with fluoxetine, bupropion also had the highest risk of hair loss.
