Can I take Colecalciferol and Trazodone together?

Why this happens

Colecalciferol and trazodone are processed by different pathways in the body and do not interfere with each other's absorption, metabolism, or effects.

What you should do

You can continue taking both medications as prescribed by your doctor. No special precautions are necessary for this specific combination.

Important precautions

Depression and mental health disorders

Trazodone can increase thoughts of self-harm or suicide, particularly when first starting the medicine or changing the dose. Monitor your mood closely and seek urgent medical help if you experience any distressing thoughts.

Drowsiness and alertness

Trazodone is highly sedating. Do not drive or operate machinery until you know how it affects you, and be aware that it can significantly increase the effects of alcohol.

Priapism (prolonged erection)

In rare cases, trazodone can cause a painful, long-lasting erection. If you experience an erection lasting more than two hours, seek emergency medical help immediately to prevent permanent damage.

Hypercalcaemia (high blood calcium)

Do not take colecalciferol if you have high levels of calcium in your blood or urine, or if you have severe kidney stones, as vitamin D increases calcium absorption and can worsen these conditions.

Food and drink warnings

Alcohol

It is best to avoid or strictly limit alcohol while taking colecalciferol. Long-term heavy alcohol use can interfere with how your body absorbs and processes Vitamin D, making the treatment less effective.

It is best to avoid or strictly limit alcohol while taking trazodone. Alcohol can significantly increase the sedative effects of this medicine, making you feel very sleepy, dizzy, or unsteady on your feet. Combining the two also increases the risk of breathing difficulties.

Grapefruit juice

Grapefruit juice can increase the amount of trazodone in your blood, which may increase the risk of side effects like extreme sleepiness or heart rhythm problems. It is best to avoid drinking large amounts of grapefruit juice.

Food (General)

Trazodone should ideally be taken with or shortly after a meal or a snack. Taking it on an empty stomach can increase the risk of feeling dizzy or lightheaded.

High-fat meals

Colecalciferol is a fat-soluble vitamin. It is best absorbed by your body when taken with a meal that contains some fat (such as eggs, avocado, nuts, or dairy).
