Amoxicillin uses


Amoxicillin treats bacterial infected that affect numerous organs. It can also be used in conjunction alongside other medications (e.g. clarithromycin, clarithromycin, Lansoprazole) for treating H. Pylori infections and duodenal ulcers.

Amoxicillin is part of the category of medications called penicillin antibiotics. It kills bacteria and hindering their growth. But, it doesn’t help with colds, flu or any other viruses.

Amoxicillin is only available on the prescription of your physician.

Before using amoxicillin, consult your doctor.  

In making a decision to take any medicine, the dangers of using the medication should be evaluated against the benefits it can bring. It’s a decision that both you and your physician will take. When you are prescribed amoxicillin, the following must be taken into account:


Discuss with your physician whether you’ve had an unusual or unrelated reaction to amoxicillin, or any other medication. Be sure to inform your health doctor if you are suffering from other allergies, like to dyes, foods or preservatives. You may also be allergic to animals. For products that are not prescription-only, you must look over the label or ingredient list carefully.


Studies that are appropriate up to now haven’t revealed issues that are specific to children, which could hinder the efficacy of amoxicillin in children. But, babies and children 3 months and under have less developed kidney functions and could require a lower dose of amoxicillin.


Studies that are appropriate so far have not revealed the existence of geriatric-specific issues that restrict the use of amoxicillin for the older. However, older patients have a higher likelihood to suffer from kidney diseases that result from age. This could require caution and an adjustment to the dosage for those taking amoxicillin.


There aren’t enough research studies on women to determine the risks to babies when using this medication while breastfeeding. Consider the benefits and the risks that could be associated with using this medication during nursing.
