Ozempic and Wegovy Linked to Improved Mental Health, But Carry Pregnancy Risks

Drugs like Ozempic and Wegovy may offer benefits beyond weight management and blood sugar control, potentially alleviating symptoms of anxiety and depression, according to recent research. But, a separate study highlights potential risks associated with their use during early pregnancy.

Mental Health Benefits Observed with GLP-1 Receptor Agonists

Both Wegovy and Ozempic contain semaglutide, a drug belonging to a class called GLP-1 receptor agonists. An international research team investigated whether using these medications was associated with improved mental health outcomes. Their findings, published in The Lancet Psychiatry, suggest a link between GLP-1 receptor agonists and a reduced risk of worsening mental illness.

Specifically, semaglutide was associated with a 44% decreased risk of worsening depression and a 38% decreased risk of worsening anxiety. Liraglutide, another GLP-1 receptor agonist sold under the brand name Saxenda, also showed a link to a lower risk of worsening depression. Researchers suggest these medications might be “dually effective therapeutic options” for anxiety and depression that occur alongside diabetes and obesity. Drugs.com provides further information on the differences between Wegovy and Ozempic.

Researchers speculate that the observed benefits could be due to factors like reduced alcohol consumption, improved body image related to weight loss, better blood sugar control in diabetes, or even direct neurobiological effects on the brain’s reward system. Eureka Health details the distinctions between the two drugs.

Pregnancy Risks Identified in GLP-1 Receptor Agonist Use

A separate study from Denmark examined the potential risks of taking GLP-1 receptor agonists during early pregnancy. Researchers analyzed data from over 480,000 pregnancies and found that exposure to liraglutide or semaglutide was associated with an increased risk of pre-term birth when used for diabetes treatment. However, this increased risk was not observed among those taking the medications for weight management.

This finding suggests that the underlying diabetes, rather than the medication itself, may be the primary factor contributing to the increased risk of pre-term birth. GoodRx offers a comparison of Wegovy and Ozempic.

Key Differences Between Ozempic and Wegovy

While both Ozempic and Wegovy contain semaglutide, they are not interchangeable. Wegovy pens contain higher doses of the drug—up to 2.4 mg per week, 20% more than the maximum dose of Ozempic (2 mg). Wegovy is specifically approved for weight loss, while Ozempic is indicated for blood sugar control in type 2 diabetes. The FDA treats them as distinct medicines, impacting insurance coverage and access. Wegovy is approved for use in adolescents aged 12 and older with obesity, while Ozempic is only approved for adults.
