Taking pregabalin and Shortec (oxycodone) together can significantly increase the risk of severe drowsiness, dizziness, and breathing difficulties. Both medications slow down the central nervous system, and when combined, their effects are much stronger than when taken alone. In serious cases, this can lead to extreme sleepiness, shallow breathing, or even coma.

Why this happens
Both drugs are 'central nervous system depressants'. Pregabalin works by calming overactive nerves, while Shortec (an opioid) works by blocking pain signals in the brain. Because they both slow down brain activity and the signals that control breathing, they have an 'additive' effect, meaning they 'double up' on these side effects.
What you should do
You should only take these two medicines together if they have been specifically prescribed this way by your doctor. If you are taking both, start with the lowest possible doses. Avoid driving or operating machinery until you know how the combination affects you. Seek urgent medical help if you experience extreme sleepiness, confusion, or slow, shallow breathing. Avoid drinking alcohol while taking these medications.

Patient picks for Drug interactions

Treatment and medication
Can I take Bisoprolol and Trimbow pmdi // pressurised inhalation together?
Bisoprolol and Trimbow (which contains formoterol) work in opposite ways on the airways. Bisoprolol may cause the airways to narrow, making it harder to breathe and potentially triggering asthma or COPD symptoms. It also makes the formoterol in the Trimbow inhaler less effective at opening your airways.

Treatment and medication
Can I take Esomeprazole and Trazodone together?
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.
