I recently came across some interesting information about the connection between Cinnarizine and weight gain. Cinnarizine is a medication commonly used to treat dizziness, vertigo, and motion sickness. It seems that this drug can sometimes cause weight gain as a side effect, but it's not entirely clear why this occurs. Some experts believe it could be related to an increase in appetite or changes in metabolism. It's important to be aware of this potential side effect and discuss it with your doctor if you're taking Cinnarizine.
