While coffee makes you alert, your body has to break it down to get rid of it. Some antibiotics can change the way your body processes caffeine, slowing its breakdown. This can cause you to feel jittery or experience headaches – surely, you don’t want that when you’re trying to recover from an infection.

The milk in caffeinated drinks also weakens the absorption of antibiotics, making your body less effective in fighting off infections. Remember, caffeine also exists in sodas, energy drinks and chocolates.

Spicy food and caffeinated drinks can worsen diarrhoea and nausea, common side effects of some antibiotics. It will be wiser to go easy or better still, avoid your favourite ‘tom yum’ and ‘kopi’ until you’ve completed the course of antibiotics!
