Side effects of fluvoxamine

Side effects of SSRIs as a group are shown below. The response to antidepressants is quite individual, so you may not get any of these side effects, or only one or two. Some side effects are temporary, and will go away a few weeks after you started taking fluvoxamine. If you find any side effects troublesome, talk to your doctor about how to manage them, or about switching to another medicine.

Remember that the risk of side effects with any medicine needs to be weighed against its benefit in treating your condition. Your doctor can help you weigh up your treatment options. See also Is this medicine right for me?
