Accrete D3 contains calcium, and high levels of calcium in the blood can increase the risk of a rare but serious heart rhythm problem (called QT prolongation) when taken with certain antidepressants like venlafaxine.

Why this happens
Venlafaxine can occasionally affect the electrical activity of the heart. High levels of calcium (from the Accrete D3) can change how the heart muscle cells react to electrical signals, potentially making this heart rhythm effect more likely.

Patient picks for Drug interactions

Treatment and medication
Can I take Codeine and Magnesium together?
Taking magnesium and codeine together can lead to increased drowsiness and may cause constipation. Magnesium can also slightly interfere with how your body absorbs codeine if taken at the exact same time.

Treatment and medication
Can I take Acetaminophen and Trazodone together?
Taking paracetamol (acetaminophen) and trazodone together is generally considered safe, but there is a small risk of increased side effects. Both substances are processed by the liver, and in some cases, taking them together might slightly increase the levels of trazodone in your blood. This could make you feel more drowsy or dizzy than usual. Additionally, both medications can occasionally affect your liver function, so using them together over a long period requires caution.
