5 things to know about antibiotics
Antibiotics work quickly and efficiently. What you need to know to make sure they have their full effect.

Take antibiotics as prescribed
It’s not the body that gets used to antibiotics, but the bacteria. When this happens, the drug no longer helps against specific bacteria, which is known as antibiotic resistance. That’s why you should only take antibiotics when it’s essential – and always follow the doctor’s instructions.
Never stop taking antibiotics without medical advice
Antibiotics often take effect very quickly, It is therefore very tempting to give them up again quickly. However, despite alleviating the symptoms, bacteria can still remain in the body and multiply again after the medication is discontinued - and subsequently even develop resistance. So it’s essential to stick to the doctor’s instructions.
Not compatible with all medications
Antibiotics may interact with other medicines, so it’s important to inform your doctor if you’re taking any other medication. Caution is advised, for example, with certain blood thinners or heartburn remedies (antacids). And: Some antibiotics such as rifampicin and rifabutin impair the effect of the contraceptive pill.
Take only with tap water
You shouldn’t consume milk or dairy products for at least two hours before and after taking certain antibiotics. The same applies to calcium-rich mineral water, fruit juice and caffeinated drinks. It’s best to swallow antibiotics with a glass of tap water.
Powerless against viruses
Antibiotics only kill bacteria, so they don’t help with infections such as bronchitis, flu, colds or a sore throat, which are usually caused by viruses.
