Antibiotics

What Are Antibiotics?

Antibiotics are medications that kill or inhibit the growth of bacteria. They do not work against viral infections like the flu, common cold, or COVID-19. The correct antibiotic depends on the type of bacteria causing the infection.

Common Bacterial Infections Treated With Antibiotics

• Urinary Tract Infections (UTIs)

• Strep Throat

• Pneumonia

• Skin Infections (e.g., cellulitis)

• Ear Infections

• Sinusitis

• Dental Abscess

• Sexually Transmitted Infections (STIs) like gonorrhea and chlamydia

Major Types of Antibiotics

1. Penicillins

• Example: Amoxicillin, Penicillin V

• Used for: Ear infections, dental infections, throat infections

2. Cephalosporins

• Example: Cephalexin (Keflex), Cefuroxime

• Used for: UTIs, skin infections, respiratory infections

3. Macrolides

• Example: Azithromycin, Erythromycin

• Used for: Respiratory infections, STIs, skin infections

4. Fluoroquinolones

• Used for: UTIs, prostatitis, pneumonia

5. Tetracyclines

• Example: Doxycycline

• Used for: Acne, Lyme disease, respiratory infections

6. Sulfonamides

• Example: Sulfamethoxazole/Trimethoprim (Bactrim)

• Used for: UTIs, bronchitis, traveler’s diarrhea

7. Carbapenems

• Reserved for serious hospital-acquired infections.

How Antibiotics Work

Antibiotics either:

• Kill bacteria directly (bactericidal)

• Prevent bacteria from multiplying (bacteriostatic)

They target bacterial structures (like cell walls or ribosomes) that human cells don’t have, making them effective and generally safe—when used correctly.
