Weight gain is one potential side effect of taking Lexapro (escitalopram). While some people might not experience weight gain during treatment with Lexapro, others might notice they are gaining weight. Just like with any medication, side effects will differ from one individual to another. It’s important to always discuss potential side effects with your doctor before starting treatment with Lexapro.

How much weight do you gain on Lexapro?

Weight gain during Lexapro treatment will differ for everyone. While some people may experience noticeable weight gain, others may not experience weight gain at all.

It is critical to discuss potential side effects of taking Lexapro with your doctor before, during and after treatment. If you begin treatment with Lexapro and are concerned about excess weight you have gained, talk with your doctor, who will be able to better explain why you are gaining weight during your treatment with Lexapro.

How can I avoid gaining weight on Lexapro?

Speak with your doctor about healthy ways to avoid gaining weight while taking Lexapro. Again, weight gain during Lexapro treatment will vary for everyone. Maintaining a healthy lifestyle is key to also maintaining a healthy weight, even when you are not taking Lexapro or other medications that may cause weight gain.

In general, some ways to maintain a healthy weight include but are not limited to:

  • Eating a healthy, well-balanced diet with plenty of vegetables and fruit
  • Drinking enough water each day
  • Avoiding alcohol
  • Exercising regularly
  • Taking care of your mental health

Your doctor will be able to provide you with a more detailed, personal plan to help you maintain a healthy weight while taking Lexapro.

Lexapro in Pediatrics

The FDA states that decreased appetite and weight loss have been associated with the use of SSRIs (selective serotonin reuptake inhibitors), including Lexapro, in pediatric patients. For this reason, the FDA also states that doctors should continually monitor both appetite and weight changes, if any, in pediatric patients prescribed an SSRI, including Lexapro. Both children and adolescents, the FDA recommends, should have their height and weight monitored throughout treatment with an SSRI.
