How does antibacterial kill bacteria

Some doctors suggest that antibiotics can reduce the effectiveness of oral contraceptives. However, research does not generally support this. Nonetheless, people who experience diarrhea and vomiting or are not taking their oral contraceptive during illness because of an upset stomach might find that its effectiveness reduces. People must not stop a course of antibiotics halfway through. If in doubt, they can ask their doctor for advice.

People usually take antibiotics by mouth. However, doctors can administer them by injection or apply them directly to the part of the body with infection.

Most antibiotics start combating infection within a few hours. Complete the whole course of medication to prevent the return of the infection. Stopping the medication before the course has finished increases the risk that the bacteria will become resistant to future treatments. The ones that survive will have had some exposure to the antibiotic and may consequently develop resistance to it.

An individual needs to complete the course of antibiotic treatment even after they see an improvement in symptoms.

Do not take some antibiotics with certain foods and drinks. Take others on an empty stomach, about an hour before meals, or 2 hours after. Follow the instructions correctly for the medication to be effective. People taking metronidazole should not drink alcohol. Avoid dairy products when taking tetracyclines, as these might disrupt the absorption of the medication. Read the article in Spanish. A recent study brings us a few steps closer to treating certain bacterial infections with bacteria-killing viruses called bacteriophages.

New research sheds light on the potential limitations of 'antibiotic cycling' as a way of combatting antibiotic resistance. New research finds high levels of antibiotic-resistant bacterial infections in children under 5 years with pneumonia in Bangladesh. What to know about antibiotics.
