Can I take Atenolol and Sertraline together?

Why this happens

Both medications can affect your heart rate and blood pressure. Sertraline can also slightly interfere with how the liver processes certain beta-blockers, potentially increasing their effect, though this is less common with atenolol than other drugs in its class.

What you should do

It is generally safe to take these together, but you should monitor how you feel. Be careful when standing up quickly from a sitting or lying position. If you feel very dizzy, experience a very slow pulse, or feel like you might faint, contact your GP.

Important precautions

Depression and anxiety disorders

You may experience an increase in suicidal thoughts or the urge to self-harm when first starting sertraline or changing the dose. This is more common in young adults under 25. Contact your doctor or go to hospital immediately if you notice any changes in your mood or behaviour.

Asthma or COPD

Atenolol can cause severe breathing difficulties or trigger a life-threatening asthma attack, even if your breathing problems are mild.

Bleeding disorders

Sertraline can increase your risk of bleeding, particularly in the stomach or skin. Use with caution if you take blood-thinning medications (like warfarin) or anti-inflammatory painkillers (like ibuprofen or aspirin).

Low sodium levels (hyponatremia)

Sertraline can cause a dangerous drop in blood sodium levels, especially in older adults. Seek medical help if you experience sudden confusion, headache, or weakness.

Stopping treatment suddenly

Never stop taking atenolol abruptly. Doing so can cause a rapid heart rate, severe chest pain, or a heart attack. Your dose must be reduced gradually by a doctor.

Food and drink warnings

Alcohol

It is recommended to avoid drinking alcohol while taking sertraline. Alcohol can increase the sedative effects of the medication, making you feel more drowsy or dizzy, and may worsen the symptoms of depression or anxiety.

It is best to avoid or strictly limit alcohol while taking atenolol. Alcohol can increase the blood-pressure-lowering effect of the medicine, which may make you feel dizzy, lightheaded, or faint, especially when standing up. Both alcohol and paracetamol (often taken for headaches) can strain the liver, so caution is advised.

Grapefruit juice

You should avoid drinking large amounts of grapefruit juice while taking sertraline. Grapefruit contains compounds that can increase the levels of sertraline in your blood, which may increase the risk of experiencing side effects.

Apple juice and Orange juice

Drinking large amounts of apple or orange juice may reduce the amount of atenolol absorbed by your body, making the medicine less effective. It is best to avoid drinking these juices in large quantities or within 2 hours of taking your dose.

Caffeine (Coffee, Tea, Energy Drinks)

Caffeine can increase your heart rate and blood pressure, which may counteract the intended effects of atenolol. While moderate intake is usually fine, avoid excessive amounts if you find it makes your heart race or increases your blood pressure.

Sertraline can sometimes cause nervousness or tremors. Consuming high amounts of caffeine may worsen these side effects or increase feelings of anxiety. It is advisable to monitor your caffeine intake.
