What can happen when you mix citalopram and grapefruit?

Mixing citalopram, an antidepressant, with grapefruit can lead to increased levels of the medication in the bloodstream. Grapefruit can inhibit certain enzymes in the liver that metabolize citalopram, potentially increasing the risk of side effects and toxicity. This interaction may enhance the medication's effects, leading to symptoms like dizziness, drowsiness, or increased heart rate. It's important to consult a healthcare professional before consuming grapefruit while on citalopram.
