Lexapro For PMDD: What Are The Benefits?

Premenstrual dysphoric disorder, or PMDD, is a frustrating condition. And if you’ve recently been diagnosed with it or are struggling to manage it, a healthcare professional might have mentioned Lexapro® for PMDD as a potential treatment. 

Treating PMDD is like treating any other mental health condition: it may take time to see results, it may take a combination of treatments and it may take more than one try to find the right combination for your needs. 

But if you’re wondering if Lexapro could be one of those potential treatments, the answer is yes.

Lexapro has a lot to offer in the way of mood disorder treatment, and there are many reasons a healthcare provider might suggest it for PMDD. 

But whether it’s right for you or not is another matter. To figure that out, you’ll need to know a few things.

Let’s start with the essential info.

How Lexapro Treats PMDD

Premenstrual dysphoric disorder, or PMDD, is a relatively new diagnostic term, but the simplest way to understand it is as a specific name for the most severe of premenstrual symptoms. 

PMDD essentially represents a collection of physical symptoms, depressive symptoms and anxiety symptoms that are interlinked with your menstrual cycle. 

The symptoms of PMDD can be both physical and emotional/psychological, and for a diagnosis, you’ll typically have several of the following symptoms:

• Depressed mood

• Hopelessness

• Anxiety

• Irritability

• Decreased interest in activities

• Difficult concentrating

• Fatigue

• Changes in appetite

• Sleep issues

• Feeling overwhelmed or out of control

• Breast tenderness or swelling

• Headaches

• Bloating

• Weight gain

• Joint or muscle pain

These symptoms are generally strong enough to interfere with your professional and social function. 

Crucially, PMDD is the diagnosis you receive when your symptoms are related to your cycle.

Where Lexapro enters the equation is that while it’s not approved by the Food and Drug Administration to treat PMDD specifically, it is sometimes prescribed in an off-label capacity to help treat it.

The Benefits of Lexapro for PMDD

First off, what is Lexapro? Well, it’s a selective serotonin reuptake inhibitor, or SSRI — an antidepressant medication that, when taken as directed, can help treat some symptoms of depression, anxiety and other mental illnesses by helping your brain to better regulate its supply of serotonin.

Serotonin is a neurotransmitter that is believed to play a role in one’s mood. Our brains produce it, but also reabsorb its supply from time to time. 

Unfortunately, some peoples’ brains absorb too much, which is believed to contribute in some part to mood disorders like depression and PMDD.

In this capacity, Lexapro may reduce the symptoms associated with PMDD, similarly to other SSRIs.

One study that looked at escitalopram for PMDD found that it provided an 80 percent reduction in one of the most commonly reported symptoms: irritability and mood changes. 

Treatment was administered during the luteal phase, which is the period of a woman’s cycle between egg release and menstruation). 

The 80 percent response was also more than double the response in placebo patients, and while it did add some adverse effects like nausea to the variables, it was seen overall as effective.

Lexapro Dosage for PMDD

That study we mentioned in the last section is the only one of substance we’ve found to date, but thankfully, it was somewhat comprehensive. 

The more than 150 women who were part of the study were divided into three groups: a placebo group, as well as escitalopram groups at 10mg and 20mg daily doses.

The 20mg group saw those great results, while the second group did not. 

In fact, the study’s authors went so far as to call 20mg a “clearly superior” dosage for treating PMDD.

For the record, 20mg is, in most cases, the maximum recommended dose of Lexapro — people with major depressive disorder tend to be started with 10mg and moved up in dosage as necessary, while in the treatment of generalized anxiety disorder, 10mg is actually considered the maximum effective dosage for safety purposes.

And those safety considerations are important because, without them, you run the risk of problems.

The Risks and Side Effects of Taking Lexapro for PMDD

It’s important to understand that, while daily dosing of Lexapro may be an effective treatment for some PMDD symptoms, it’s technically not approved by the FDA for PMDD treatment. 

Lexapro may increase your risk of any of the following common side effects:

• Fatigue

• Dry mouth

• Diarrhea

• Constipation

• Indigestion

• Abdominal pain

• Flu-like symptoms

• Insomnia

• Dizziness

• Sweating

• Sexual performance and libido issues

Serious side effects may include increased suicidal thoughts, abnormal bleeding, eye pain and vision problems, as well as an increase in your risk of experiencing serotonin syndrome, which may be deadly.

Also, you should generally avoid suddenly stopping this prescription medication, as sudden discontinuation could cause irritability, sweating, dizziness, nausea, shaking and anxiety.
