Can solifenacin tablets cause weight increase?

Yes, solifenacin tablets can cause weight increase as a side effect. Weight gain is a possible adverse effect of solifenacin, with an incidence rate of approximately 1-2% in clinical studies. The exact mechanism by which solifenacin causes weight gain is not fully understood, but it may be related to its anticholinergic properties. Anticholinergic medications can slow down the movement of food through the digestive tract, leading to constipation and increased water absorption, which can contribute to weight gain. Additionally, solifenacin may also affect appetite and metabolism, further contributing to weight gain. If you are experiencing weight gain while taking solifenacin, talk to your doctor about it. They can assess your situation and provide appropriate advice or alternative treatment options.
