A Comprehensive Guide on the Lexapro Side Effects

1. Suicidal Thoughts and Behaviors

Like any other antidepressant, Lexapro can increase the risk of having suicidal thoughts and characteristics, especially in adults under 25 years, adolescents, and children. Such risk is determined during the initial treatment months or when there is an adjustment in the dosage.

Such patients require close monitoring for any worsening of depression or unusual changes in behavior. Caregivers and family members must be vigilant to notice the emergency of suicidal thoughts from the conversations they have with patients.

2. Serotonin Syndrome Lexapro Side Effects

Serotonin syndrome is a life-threatening condition facilitated by the production of excess serotonin in your central nervous system. This problem occurs when you take Lexapro with other drugs that increase the level of serotonin.

The Lexapro side effects here include rapid heart rate, hallucinations, agitation, confusion, and high fever. When you experience gastrointestinal complications like nausea and vomiting, it could be a sign of serotonin syndrome caused by Lexapro. If you suspect you are experiencing such a syndrome, you must seek immediate medical attention from your doctor.

3. Severe Allergic Reactions

When you take drugs with different components, you are likely to have an allergic reaction. This occurs when you take medications with components that have adverse reactions in the body. However, in sporadic cases, you are likely to experience severe allergic reactions, including anaphylaxis.

Most Lexapro side effects are medical emergencies because of the severe symptoms linked with this drug. Some symptoms of anaphylaxis include rash, swelling, severe dizziness, and difficulty breathing. When you see any of these symptoms after taking Lexapro, you must seek medical help before things go sour.

You should also give your doctor a list of all the drugs you are using currently to avoid potential interactions that could lead to severe side effects. Regularly do follow-ups with your provider to monitor your response to Lexapro and make necessary adjustments if there are traces of adverse effects.
