Esomeprazole may reduce the amount of trazodone that your body absorbs. This could potentially make trazodone less effective at treating your symptoms (such as depression or sleep issues). Additionally, both medications can rarely affect the electrical activity of your heart, though this risk is generally low.

Why this happens
Esomeprazole reduces stomach acid. Trazodone needs an acidic environment to dissolve properly so it can be absorbed into the bloodstream. Lower acid levels mean less medicine gets into your system. There is also a theoretical risk of 'QT prolongation' (a change in heart rhythm) when these types of drugs are used together.
What you should do
Back to contentsYou can generally take these together, but monitor your mood or sleep patterns closely. If you feel your trazodone is not working as well as it used to, or if you experience any unusual heart palpitations or dizziness, speak with your doctor. They may need to adjust your dose or the timing of when you take your tablets.

Important precautions
Back to contentsDrowsiness and alcohol interaction
Trazodone is highly sedating. You must not drink alcohol while taking it as this will dangerously increase the sedative effect. Do not drive or operate machinery until you know how it affects you.
Priapism (prolonged erection)
In rare cases, trazodone can cause a painful, persistent erection. If you experience an erection lasting more than two hours, seek emergency medical help immediately to prevent permanent damage.
Severe diarrhoea (C. difficile) - esomeprazole
Seek medical help if you develop severe or persistent watery diarrhoea, as this medicine can increase the risk of a serious bowel infection.
Vitamin B12 deficiency and bone fractures - esomeprazole
Long-term use (over a year) can weaken bones and lead to low magnesium or B12 levels; your doctor should monitor these if you are on long-term treatment.
Severe kidney or liver disease
Your doctor may need to prescribe a lower dose, as your body will take longer to clear esomeprazole.
Magnesium deficiency
Taking esomeprazole for more than three months can cause your blood magnesium levels to drop significantly, leading to fatigue, muscle spasms, or dizziness.
Masking stomach cancer symptoms
Esomeprazole can hide the symptoms of stomach cancer. You must tell your doctor if you have unexplained weight loss, persistent vomiting, or difficulty swallowing before starting this medicine.
Food and drink warnings
Back to contentsAlcohol
While alcohol does not directly interact with esomeprazole, it can increase stomach acid production and irritate the stomach lining, which may worsen the symptoms your medicine is intended to treat. It is best to limit alcohol intake.
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. It can also increase the risk of breathing difficulties.
Grapefruit juice
Avoid drinking large amounts of grapefruit juice. Grapefruit can increase the level of trazodone in your blood, which may increase the risk of side effects.
Caffeine
Caffeine (found in coffee, tea, and some fizzy drinks) can trigger or worsen acid reflux and heartburn. This may make esomeprazole less effective at managing your symptoms.
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.

Can I take Levothyroxine and Vitamin D together?
There is no direct harmful interaction between levothyroxine and vitamin D. In fact, many people take them together because vitamin D deficiency is common in people with thyroid conditions. However, if your vitamin D supplement also contains calcium, it can significantly interfere with how your body absorbs your thyroid medication.
