Depression is common among adults but is no less common in children. People above 12 years go through this condition. Millions of Americans face depression because of many reasons. 

Symptoms may vary according to the person and the mental behaviour they have been through. Normal symptoms would look like feeling sad, angry, losing interest in everything, tiredness, facing disturbed sleep and many more. At that moment, Lexapro comes into place, which helps through the condition.

While you are about to take Lexapro, it is always necessary to know what all things you can consume to avoid any trouble. You should know would it be beneficial to drink alcohol while on Lexapro.

What Is Lexapro?

Lexapro is an anti-depressant belonging to a group of drugs called selective serotonin reuptake inhibitors (SSRIs). Its generic name is escitalopram. It works by preventing serotonin from being reabsorbed, resulting in an increased amount in the brain. Serotonin is a neurotransmitter that affects one's mood and well-being. This alteration helps in treating people suffering from anxiety and depression.


By preventing the reuptake of serotonin into the presynaptic neuron, escitalopram raises Intra synaptic levels of the neurotransmitter. Escitalopram has the highest selectivity for the serotonin transporter (SERT) compared to the norepinephrine transporter (NET) of all the SSRIs now available, resulting in a milder side-effect profile than less-selective SSRIs.

Escitalopram is a P-glycoprotein substrate, P-glycoprotein inhibitors like verapamil and quinidine, it may help it cross the blood-brain barrier. Escitalopram's antidepressant-like effects were improved in preclinical research in rats when it was combined with a P-glycoprotein inhibitor.

Study On The Interaction Of Alcohol With Lexapro

A study conducted at the Department of Mental Health and Alcohol Research, Finland, it shown that in the clinical environment, alcoholism combined with major depressive disorder provided a significant issue. The outcomes of using selective serotonin reuptake inhibitors to treat depression have been variable.

According to the study, eighty alcohol-dependent individuals with major depressive disorder were randomized 1:1 to receive escitalopram 20 mg in municipal alcohol clinics. Patients received their usual care at the clinics during the 26-week research period. The patients were seen weekly for the first month, then every three and six months after that. The Alcohol Use Disorders Identification Test (AUDIT), the Obsessive-Compulsive Drinking Scale (OCDS), and the Drinking Diary were used as outcome measures.

In both groups, the completion rate was high, especially among the patients who had been abstinent at the start of the research. However, those who were not abstinent dropped out. Alcohol intake, as judged by the AUDIT QF (quantity-frequency) score, and alcohol craving, as measured by the OCDS, were both considerably reduced in both groups. Early commencement of the first depressive episode, like early onset of the first alcohol intoxication, predicted poor treatment results in patients treated with escitalopram.

If you drink while on Lexapro, you will not feel any more intoxicated than you would usually. On the other hand, combining anti-depressants and alcohol is not advised: it can be lethal and harmful. (Muhonen LH, Lahti J, Sinclair D, Lönnqvist J, Alho H.2008 Oct)

Make sure you take the skipped dose as soon as possible but skip it if it is almost time for your next dose.
It may be safe to have an occasional intake of alcohol. However, a person should consult a doctor before consuming alcohol with any anti-depressant.
No. Lexapro is an SSRI drug taken for anxiety and depression, the consumption being limited to once daily. In contrast, Xanax is a benzodiazepine taken for anxiety and panic disorders, consumption extending to 3 to 4 times a day.

Bottom Line From Practical Anxiety Solutions

Lexapro is an anti-depressant used to treat anxiety and depression. It works by assisting in the restoration of a natural substance (serotonin) equilibrium in the brain. If not taken cautiously, it could cause painful urination, swelling, stiffness of muscles, low sodium levels, and so on. It is suggested not to take Lexapro with alcohol as it can be harmful or, at worst, lethal.
