Antibiotics fight bacterial infections, but they don’t work on viruses like colds or most sore throats. Using the wrong antibiotic or stopping early fuels resistance and leads to worse infections later. This page gives straight, practical guidance so you get the benefit and avoid common risks.
Doctors don’t guess. They look at where the infection is (ear, lung, skin), how severe it is, your allergies, and recent antibiotic use. For serious or unusual infections they may order a culture and sensitivity test—this tells them which drug is most likely to work. Sometimes they start a broad-spectrum antibiotic when they need to act fast, then switch to a narrow-spectrum drug once results come back. Narrow-spectrum drugs target specific bacteria and usually cause less harm to your normal flora.
Common choices: amoxicillin is often used for ear and sinus infections, Augmentin covers bacteria that make certain enzymes, macrolides like azithromycin help if you’re allergic to penicillin, and doxycycline is used for some skin and respiratory infections. More powerful drugs, like fluoroquinolones or IV antibiotics, are reserved for resistant or severe cases.
Take the antibiotic exactly as prescribed. If the label says three times daily, space doses roughly evenly. Finish the prescribed course unless your doctor tells you to stop—stopping too soon can leave surviving bacteria that grow back resistant. Don’t save leftovers for later or share antibiotics with others.
Watch for side effects: nausea, diarrhea, rashes, and, rarely, allergic reactions. Severe symptoms like wheezing, swelling, fainting, or a spreading rash need urgent care. Some antibiotics interact with other meds—warfarin, some heart drugs, and certain supplements can be affected. Ask your pharmacist or doctor before combining medicines.
Alcohol isn’t safe with all antibiotics. Metronidazole and tinidazole can cause severe nausea and flushing with alcohol. Also consider probiotics during or after treatment to reduce antibiotic-associated diarrhea—choose a product with lived cultures and follow label directions.
To lower the chance of resistance: avoid asking for antibiotics for viral illnesses, complete tests your doctor orders, get vaccinated to prevent infections, and practice good hygiene like handwashing. If infections recur or don’t improve in 48–72 hours, contact your provider—do not switch drugs on your own.
