Antidepressants differ in side-effects such as weight gain, UK research finds

Notable variations between different medications were found in weight gain or loss, heart rate and blood pressure

People taking certain types of antidepressants can gain up to 2kg (4.5lbs) in weight within the first two months of treatment, while patients taking other drugs can lose the equivalent or more, according to a major review of potential side-effects.

The research, led by academics at King's College London and the University of Oxford, found that while some antidepressants can cause notable changes in body weight, heart rate and blood pressure, others do not cause such physical changes.
