Amoxicillin: Frequently Asked Questions Answered

What is amoxicillin?

Amoxicillin is a penicillin-based antibiotic and is a close relative of ampicillin. It can kill bacteria like the Streptococcus species, E. coli, Listeria monocytogenes, Actinomyces, Shigella, Salmonella, and Clostridial species. This antibiotic belongs to a specific class of beta-lactam drugs.

Amoxicillin works by inhibiting specific bacterial cells. The proteins function to bind and break down bacterial walls. This process is called bactericidal killing.

The different brand names that amoxicillin is available under are Amoxil, Moxatag, and Trimox.

  • Tonsillitis
  • Bronchitis
  • Ear infections
  • Nose infections
  • Dental pain
  • Bacterial pharyngitis
  • Skin infections
  • Genitourinary tract infections

Do not self-medicate.

3. Can amoxicillin treat cough?

Studies have recently concluded that amoxicillin offers no benefit if taken to treat cough or reduce its symptoms. Most of the lower respiratory tract diseases are caused by viruses. Therefore, the efficacy of antibiotics does not come into play here. Overuse of antibiotics will lead to bacteria becoming resistant to them later. It is advised to take medication only under the surveillance of a doctor.

4. Can amoxicillin treat hemorrhoids?

Infected hemorrhoids need medical attention. Antibiotics are suitable to treat such disorders. However, doctors prefer to prescribe doxycycline in cases of hemorrhoids. Your physician will evaluate your condition thoroughly to select a suitable antibiotic for you. It will depend upon the severity of your condition and reactions to certain medicines.

5. Can I buy amoxicillin without a prescription?

Antibiotics like amoxicillin resolve a wide array of health issues.

Caffeine reacts with 55 drugs! A few studies, such as one in 2008, have revealed that the benefits of amoxicillin were accelerated when taken along with caffeine. However, these studies have not been widely accepted. So although, there are no adverse reactions in co-administering them, a doctor's consultation is a must before starting any antibiotic.

7. Is amoxicillin a good antibiotic for pneumonia?

Amoxicillin is the preferred drug for pneumonia. It is highly effective in its treatment, and people have recovered entirely after taking this drug. However, if you are allergic to penicillin or amoxicillin, you must pass this information to your doctor. The doctor will then prescribe an alternative antibiotic to you.

8. Is amoxicillin good for sore throat?

For treating sore throat, it is essential to know the type of pathogen responsible for the infection. Viruses cause ninety percent of sore throats, which antibiotics cannot treat. But amoxicillin can effectively treat sore throat that has resulted due to a bacterial infection. Do not self-medicate and consult a doctor to determine the type of infection.

9. What drugs interact with amoxicillin?

Talk to your doctor to know which infection has caused you the fever before taking any medications.
