What medications are Lexapro and Zoloft?
Lexapro (escitalopram) and Zoloft (sertraline) are both antidepressant medications belonging to the class of selective serotonin reuptake inhibitors (SSRIs). They work by increasing the levels of serotonin in the brain, which helps to improve mood and reduce symptoms of depression and anxiety.
What are they commonly used for?
Both Lexapro and Zoloft are commonly prescribed for the treatment of major depressive disorder (MDD), generalized anxiety disorder (GAD), panic disorder, social anxiety disorder, and obsessive-compulsive disorder (OCD). [1]
How do they compare in terms of side effects?
While both medications can cause similar side effects, Lexapro tends to cause more drowsiness, fatigue, and sedation than Zoloft, according to a study published in the Journal of Clinical Psychopharmacology. [2] Conversely, Zoloft may cause more gastrointestinal side effects, such as diarrhea and nausea.
Which one is more likely to cause weight gain or loss?
Lexapro is more likely to cause weight gain compared to Zoloft, especially in the initial stages of treatment. However, both medications can affect appetite and weight, and individual results may vary.
When was each medication approved by the FDA?
Lexapro was approved by the FDA in 2002 for the treatment of MDD and GAD. Zoloft, on the other hand, was approved in 1991 for the treatment of MDD and GAD.
Can I switch from one medication to the other?
While both medications are SSRIs, switching from Lexapro to Zoloft or vice versa should only be done under the guidance of a healthcare professional. Stopping or switching medications too quickly can lead to withdrawal symptoms and a potential increase in side effects.
What are the patent expiration dates for each medication?
Lexapro's patent has expired, which means that generic versions of the medication are now available. Zoloft's patent has also expired, and generic versions are available as well. However, the generic versions may have slightly different active ingredients or excipients, which can affect their absorption and efficacy.
