Experts say that up to 25% of people taking antidepressant medication, including popular SSRIs (Selective serotonin reuptake inhibitors) drugs like Lexapro, Paxil, Prozac, and Zoloft, can cause weight loss gain of 10 pounds or more. (Aronne, L.J. and Segal, K.R., 2003.).

Study On SSRI Antidepressant And Weight Gain:

Aim: This study aimed to look into the link between antidepressant use and weight increase and the effects of lifestyle factors.

Method: They used data of 2334 adults of the North West Adelaide health study.

Findings: 188 (8.1%) participants had a mean annual number of 1-2 antidepressants prescriptions, and 212 (9.1%) had over two drugs. The yearly mean weight gain was 0.12, 0.18, and 0.28 kg in non-users, low (1–2 prescriptions/year) and high (>2 prescriptions/year) antidepressant users, respectively.

Antidepressant usage was positively linked with weight gain in multivariable regression models, with high antidepressant users gaining an extra 0.22 kg per year. This link was primarily related to using selective serotonin reuptake inhibitors (SSRIs). High SSRI users gained 0.48 kg more than non-users.

Conclusion: SSRI was associated with weight gain in the presence of unhealthy behaviors, including western diets and smoking.

Factors Affecting The Weight Gain Of Paxil?

Several factors may affect the weight gain of Paxil:

  • The use of other medications can contribute to weight gain, especially if they are psychiatric.
