What Are Antibiotics?
Antibiotics are medications designed to treat bacterial infections. They work by either killing bacteria or stopping their growth.
However, antibiotics do not work against viral infections like the flu, colds, or coughs. Using them correctly can help treat bacterial diseases and even save lives.
You can buy antibiotics online and offline, but a valid prescription is required.
Your immune system usually fights bacteria before they cause symptoms. White blood cells attack harmful bacteria, and in many cases, your body can clear infections without medication.
However, antibiotics are necessary to eliminate the bacterial infection when the bacterial load is too high.
The first antibiotic, penicillin, was discovered in 1928. Today, penicillin-based antibiotics like amoxicillin, penicillin G, and ampicillin are widely used.
What Are the Uses of Antibiotics?
Most bacteria in your body are harmless, but some can cause infections. Antibiotics help treat these bacterial infections effectively.
Common infections treated with antibiotics:
- Dental infections
- Ear and sinus infections (e.g., Otitis Media)
- Respiratory tract infections
- Whooping cough
- Skin infections
- Clostridioides difficile (C. diff)
- Bacterial pneumonia
- Meningitis (inflammation of the brain and spinal cord)
- Urinary tract infections (UTIs)
- Strep throat
- Bladder and kidney infections
Why We Need Antibiotics
Antibiotics are essential for treating bacterial infections like E. coli, UTIs, and strep throat.
However, taking them unnecessarily can lead to serious side effects and contribute to antibiotic resistance.
Antibiotics are only effective against bacterial infections. Conditions like the common cold, stomach flu, bronchitis, and sore throats caused by viruses will not respond to antibiotics.
In such cases, doctors may recommend antiviral medications instead.
Some antibiotics are broad-spectrum, meaning they work on various bacteria. Others are narrow-spectrum, targeting specific bacteria.
Antibiotics are usually taken orally, but doctors may prescribe injections or topical applications for certain infections.
Most antibiotics start working within a few hours, but it’s crucial to complete the entire course to prevent recurrence.
Certain antibiotics must be taken on an empty stomach for better absorption, while others should not be mixed with alcohol (e.g., metronidazole).
To maximize effectiveness, follow your doctor's instructions carefully.
How Do Antibiotics Work?
Antibiotics work in two main ways:
- Bactericidal Antibiotics – Kill bacteria by breaking their cell walls (e.g., penicillin).
- Bacteriostatic Antibiotics – Stop bacteria from multiplying, allowing the immune system to clear the infection.
Main Types of Antibiotics
Different types of antibiotics target specific bacterial infections.
Common antibiotic classes:
- Penicillins – Amoxicillin, penicillin G, flucloxacillin
- Macrolides – Azithromycin, erythromycin, clarithromycin
- Cephalosporins – Cefalexin, cefadroxil, cefaclor
- Metronidazole & Tinidazole – Used for anaerobic infections
- Tetracyclines – Doxycycline, tetracycline, lymecycline
- Aminoglycosides – Gentamicin, tobramycin
- Quinolones – Ciprofloxacin, levofloxacin, norfloxacin
- Nitrofurantoin – Used primarily for UTIs
- Sulfonamides & Trimethoprim – Co-trimoxazole (Bactrim, Septrin)
Some antibiotics are reserved for serious infections, such as tuberculosis (TB).
How to Take Antibiotics?
Antibiotics come in different forms depending on the infection type.
Common administration methods:
- Oral – Pills, liquids, or capsules.
- Topical – Sprays, creams, ointments, eye drops.
- Injectable – Injections or IV (for severe infections).
Your doctor will tell you when and how to take antibiotics, including whether to take them before or after meals.
Always follow your doctor’s instructions to ensure effectiveness and avoid resistance.
