Can I take Azithromycin and Terbutaline together?

Why this happens

Both of these medicines have the potential to slightly affect the electrical activity of your heart (specifically, they can prolong the 'QT interval'). When used at the same time, their effects can add together, making an irregular heartbeat more likely.

Speak to your doctor before taking these together, especially if you have a history of heart problems or low levels of potassium or magnesium in your blood. If your doctor has prescribed both, follow their instructions closely. Seek immediate medical help if you feel your heart is beating irregularly, or if you feel faint or dizzy.

Heart rhythm disorders (Long QT syndrome)

Azithromycin can cause serious changes to your heart rhythm. You must inform your doctor if you have a history of heart palpitations, a slow heart rate, or a family history of 'Long QT syndrome'.

Diabetes

Terbutaline can cause your blood sugar levels to rise. If you have diabetes, you may need to monitor your blood glucose more frequently when starting treatment or increasing your dose.

Caffeine (Coffee, tea, energy drinks, cola)

Terbutaline is a stimulant that can increase your heart rate. Consuming caffeine while taking this medicine may increase the risk of side effects like a racing heart, palpitations, or feeling shaky/jittery.

Food (General)

If you have been prescribed azithromycin in capsule form, you must take it at least 1 hour before food or 2 hours after food. Food significantly reduces the absorption of the capsules. Note: This does not apply to azithromycin tablets or liquid suspension, which can be taken with or without food.
