Vraylar wasn’t reported to specifically cause brain fog. But it’s possible that the drug could cause side effects that would be considered to be brain fog. Another name for brain fog is mental fatigue.
Brain fog isn’t a medical condition. But it can be a symptom of other conditions or a side effect of certain medications.
In clinical trials, Vraylar caused some side effects that are similar to symptoms of brain fog. These side effects included sleepiness and fatigue (lack of energy).
Keep in mind that brain fog can be a symptom of the conditions Vraylar is used to treat. For example, people with bipolar I disorder may have trouble concentrating during a depressive episode.
If you experience brain fog while taking Vraylar, talk with your doctor. They may recommend ways to help ease it. They may also recommend a different medication for your condition.
