What You'll Learn
Lexapro and serotonin syndrome
Lexapro (escitalopram) is a selective serotonin reuptake inhibitor (SSRI) that increases serotonin levels in the brain. This increase in serotonin helps to suppress the ill effects of depression or anxiety. While Lexapro is generally well-tolerated, it can cause side effects in some people, such as insomnia, nausea, increased sweating, and nervousness.
In rare cases, the use of Lexapro has been associated with serotonin syndrome. Serotonin syndrome is a serious and potentially life-threatening drug reaction that occurs when there is an excessive accumulation of serotonin in the body. It is typically caused by taking drugs or medications that affect serotonin levels, such as combining an antidepressant with a migraine medication or an opioid pain medication. Serotonin syndrome can also occur when there is an intentional overdose of antidepressant medications.
The symptoms of serotonin syndrome can range from mild to severe and include agitation, fever, rapid heart rate, seizures, and twitching muscles. Mild symptoms may include diarrhea, nausea, nervousness, and shivering. If left untreated, severe serotonin syndrome can be fatal.
If you suspect that you are experiencing serotonin syndrome after starting or increasing the dosage of Lexapro, it is important to contact your healthcare provider immediately or seek emergency medical attention. The main treatment for serotonin syndrome is to stop taking the drug(s) that are causing the syndrome.

Lexapro and low sodium levels
Lexapro is the brand name for the drug escitalopram, a selective serotonin reuptake inhibitor (SSRI) commonly used to treat depression and anxiety. It works by increasing serotonin levels in the brain, which helps to regulate the neurochemical imbalance that causes depression and anxiety.
While Lexapro is generally well-tolerated, it can cause side effects in some people. These side effects are usually mild and transient, and they decrease in intensity and frequency as treatment continues. Common side effects include insomnia, diarrhoea, restlessness, fatigue, nervousness, dry mouth, and sweating.
However, in rare cases, Lexapro has been associated with hyponatremia, or low sodium levels in the blood. Hyponatremia is characterised by a serum sodium level of less than 135 mmol/L, elevated urine osmolality, and elevated urine sodium levels. While the exact mechanism is not fully understood, it is believed that SSRIs like Lexapro may induce hyponatremia, through a syndrome of inappropriate antidiuretic hormone secretion (SIADH), which is caused by a nonosmotic release of antidiuretic hormone.
The risk of developing hyponatremia while taking Lexapro is higher in certain populations, including women, individuals over the age of 65, and those taking multiple drugs that may also lower sodium levels. Symptoms of hyponatremia include constant headaches, long-lasting confusion or weakness, and frequent muscle cramps. In severe cases, hyponatremia can lead to seizures, severe agitation, and a decline in mental status.
If you experience any symptoms of hyponatremia while taking Lexapro, it is important to seek medical advice and discontinue the medication under the guidance of a healthcare professional.

Lexapro and sexual problems
Lexapro is the brand name for the drug escitalopram, a selective serotonin reuptake inhibitor (SSRI) used to treat major depressive disorder and generalized anxiety disorder. It is generally well-tolerated, but like all medicines, it can cause side effects, including sexual problems.
Sexual side effects from Lexapro are very common. Research suggests that about half of Lexapro users experience sexual issues. These issues are more common in men than in women, with 9 to 14% of men reporting ejaculation disorders and 3% reporting erectile dysfunction. Women are also affected, with 2% reporting menstrual disorders such as cramps, prolonged periods, or heavy bleeding.
The sexual side effects of Lexapro include decreased sexual desire and anorgasmia (delayed, infrequent, or absent orgasms) in both men and women. Men may experience delayed ejaculation, while women may experience delayed or absent orgasms. These side effects are often referred to as antidepressant-induced sexual dysfunction and are related to the drug's effects on serotonin, which is involved in the human sexual response. Specifically, the increase in serotonin activity caused by Lexapro is thought to affect testosterone and dopamine, which are closely involved in sexual arousal and function.
If you experience sexual side effects while taking Lexapro, it is important to consult your healthcare provider. They may suggest adjustments to your dosage or the timing of your medication. They may also recommend switching to a different antidepressant that is less likely to affect your sex life. Additionally, non-medical strategies such as talking to your partner, therapy, and changing your sexual routines can help you manage these side effects.
It is worth noting that many sexual issues mentioned above can also occur as a result of the underlying depression and anxiety that Lexapro is prescribed to treat, rather than solely due to the medication itself. Lexapro may also cause other side effects, such as weight gain, joint pain, sweating, tiredness, nausea, dry mouth, constipation, and nervousness. These side effects typically improve as your body adjusts to the medication and are generally mild and transient.

Lexapro and discontinuation
Lexapro (escitalopram) is a prescription medication approved by the U.S. Food and Drug Administration (FDA) to treat major depressive disorder and generalized anxiety disorder. It is a selective serotonin reuptake inhibitor (SSRI) and belongs to a category of drugs that have long been associated with withdrawal symptoms after stopping their use.
Physicians refer to Lexapro withdrawal symptoms as "antidepressant discontinuation syndrome". However, many believe that this name minimizes the seriousness of the effects experienced. Common symptoms of Lexapro withdrawal include dizziness, muscle tension, chills, crying, and brain fog. More than one in four people experience these symptoms, according to a Japanese study. Other symptoms include confusion, difficulty concentrating, digestive issues (nausea, vomiting, cramps, diarrhea, or appetite loss), and flu-like symptoms (headache, muscle pain, weakness, and tiredness).
Withdrawal from Lexapro is not always easy, and quitting cold turkey may increase the likelihood of severe withdrawal. The best way to find relief from Lexapro withdrawal is to avoid it altogether. To do this, schedule an appointment with the prescribing physician to discuss a strategy to get off the medication as safely as possible. The most effective way to minimize symptoms of withdrawal is to slowly taper off the medication. Tapering involves adjusting the dose by small amounts, gradually decreasing it so the body gets used to lower levels of the medication.
