Additionally, acetazolamide can affect the levels of salts (electrolytes) in your blood, which may increase the risk of a rare but serious heart rhythm problem associated with quetiapine.

Treatment and medication
Can I take Empagliflozin and Mirtazapine together?

Treatment and medication
Can I take Abilify and Fluoxetine together?
Taking fluoxetine with Abilify (aripiprazole) can significantly increase the amount of Abilify in your bloodstream. This makes you much more likely to experience side effects such as extreme sleepiness, restlessness (feeling like you cannot sit still), uncontrollable body movements (tremors or twitching), and dizziness. There is also a small but serious risk of a heart rhythm problem called QT prolongation.
