Should antibiotics be taken before or after meals?

Taking antibiotics before or after meals will affect the effectiveness of the drug. Depending on the characteristics and dosage form of each antibiotic, there are different times to take it. Some antibiotics are taken after meals, others before, and some even during meals. Therefore, it is essential to consult a doctor before using any medication.

1. Should you take antibiotics before or after meals?

When you take medication, food in the intestines may affect the absorption process of the drug. This is called the interaction between drugs and food. The interaction can be beneficial or harmful depending on the timing of taking the medication. Additionally, the characteristics of the antibiotics, the dosage form, and the excipients,... also determine the timing of taking the medication.
Some types of oral antibiotics need to be taken away from meals because food can affect their absorption. Because they can cause intestinal irritation and discomfort, such as: penicillin group; cephalosporin group; macrolide group.... Other types of antibiotics that need to be taken with meals or immediately after eating to avoid side effects on the digestive system, such as: the quinolone group; the nitroimidazole group; the cyclin group...

Especially antibiotics in the form of enteric-coated tablets are not affected by food, but it is ideal for patients to take them on an empty stomach. Note that when using, it should be taken with cooled boiled-water.
Moreover, the type of food consumed alongside the medication also affects the drug's efficacy. For example, milk and dairy products are recommended to be limited while taking antibiotics. Because the calcium in milk can reduce the therapeutic effect of the medication, hindering the absorption process.
