Can I take Bronco cough medicine and Serlan together?

Drug interaction guide

Taking these two medicines together can increase the risk of a rare but serious condition called 'serotonin syndrome'. This happens when there is too much of a chemical called serotonin in your brain. Symptoms can include feeling very agitated, confused, shaky, sweaty, or having a fast heartbeat and muscle twitches. Additionally, the cough medicine may make you feel more drowsy or dizzy than usual.

Why this happens

Serlan (sertraline) is an SSRI antidepressant that increases serotonin levels. Bronco cough medicine contains dextromethorphan, which also slightly increases serotonin. When combined, they can raise serotonin to unsafe levels. Furthermore, both medicines can have a calming effect on the central nervous system, leading to increased sleepiness.

What you should do

You should speak to your doctor or pharmacist before taking these together. They may suggest a different type of cough medicine that does not contain dextromethorphan (such as a simple linctus or a medicine containing only guanifenesin). If you are already taking both and feel very unwell, confused, or have a high fever, seek medical help immediately.

Important precautions

Bleeding disorders or use of blood thinners

Serlan can increase your risk of serious bleeding, especially if you are also taking aspirin, ibuprofen, or blood-thinning medications like warfarin.

Bipolar disorder or history of mania

This medicine can trigger a manic episode (extreme high mood and overactivity) in people with undiagnosed bipolar disorder.

Serotonin Syndrome risk

Check with a pharmacist before using certain cough suppressants (like dextromethorphan) with Serlan, as the combination can cause a life-threatening reaction called serotonin syndrome.

Food and drink warnings

Alcool

You should avoid drinking alcohol while taking Serlan. Combining alcohol with this medicine can increase side effects like drowsiness, dizziness, and impaired concentration.

Grapefruit juice

Avoid consuming large amounts of grapefruit juice. Grapefruit can increase the levels of sertraline in your blood, which may increase the risk of side effects.
