What Bacteria Does Amoxicillin Not Treat?

Amoxicillin is a widely-used antibiotic used to treat a variety of bacterial infections. While it is effective in treating many types of infections, there are certain bacteria that amoxicillin is not effective against. Knowing which bacteria amoxicillin is not effective against can help users make sure they are using the right antibiotic for their infection.

Types of Bacteria Not Treated by Amoxicillin

Amoxicillin is an antibiotic in the penicillin family. That means it is effective against many types of bacteria, including:

• Staphylococcus
• Streptococcus
• E. coli
• H. pylori
• Salmonella

However, there are certain types of bacteria that amoxicillin does not treat. These include:

• Methicillin-resistant Staphylococcus aureus (MRSA)
• Pseudomonas aeruginosa
• Enterococcus
• Mycobacterium tuberculosis

These bacteria are resistant to amoxicillin and other penicillin-based antibiotics. Therefore, if you are suffering from an infection caused by any of these bacteria, you will need to seek treatment with an alternate antibiotic.

Augmentin vs. Amoxicillin

Augmentin is a combination antibiotic made up of amoxicillin and clavulanate potassium. It is effective against many of the same types of bacteria as amoxicillin, but it is also effective against some bacteria that amoxicillin is not, such as Enterococcus and MRSA. Therefore, if you have an infection caused by one of these bacteria, your doctor may prescribe Augmentin instead of amoxicillin.

Treating Bacterial Infections

When treating a bacterial infection, it is important to make sure you are using the right type of antibiotic. If you are prescribed amoxicillin and the infection is not improving, it may be because the bacteria causing the infection is not susceptible to amoxicillin. In this case, your doctor may recommend an alternate antibiotic or combination antibiotic such as Augmentin. It is also important to take antibiotics as prescribed. This means taking the full course of antibiotics even if you feel better after a few days. Taking the full course of antibiotics helps ensure that all the bacteria causing the infection are killed and helps prevent the development of antibiotic-resistant bacteria.

Conclusion

Amoxicillin is an effective antibiotic for treating many types of bacterial infections. However, there are certain types of bacteria that amoxicillin does not treat, such as MRSA and Pseudomonas aeruginosa. If you have an infection caused by one of these bacteria, your doctor may recommend an alternate antibiotic or combination antibiotic such as Augmentin. It is also important to take antibiotics as prescribed to ensure all the bacteria causing the infection are killed and to prevent the development of antibiotic-resistant bacteria.
