What is amoxicillin/clavulanate potassium?
Amoxicillin/clavulanate potassium is an antibacterial prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of certain bacterial infections, such as infections of the ear and sinus; skin; urinary tract; and lower respiratory tract (including pneumonia).
Community-acquired pneumonia, a bacterial respiratory disease, can be an opportunistic infection (OI) of HIV.

Before taking amoxicillin/clavulanate potassium, tell your health care provider:
- If you are allergic to amoxicillin, clavulanate, other beta-lactam antibacterial medicines (such as penicillin or cephalosporin antibiotics), or any other medicines.
- About any medical conditions you have or have had, especially:
- Liver problems
- Kidney problems, including if you are receiving dialysis
- Allergies, hay fever, eczema, asthma
- Mononucleosis (also called "mono")
- Phenylketonuria (PKU). The artificial sweetener (aspartame) in amoxicillin/clavulanate potassium chewable tablets and oral suspension contains phenylalanine. Phenylalanine may be harmful to people with PKU.
- About anything that could affect your ability to take medicines, such as difficulty swallowing or remembering to take pills.
- If you are pregnant or plan to become pregnant. Talk to your health care provider about the risks and benefits of taking amoxicillin/clavulanate potassium during pregnancy.
- If you are breastfeeding or plan to breastfeed. For mothers with HIV in the United States, the Guideline recommends speaking with your health care provider to discuss options for feeding your baby. Mothers with suppressed viral load have a less than 1% chance of transmitting HIV to their baby via their own milk. Although most medicines are safe to use while breastfeeding, some medicines should be avoided. Always let your health care provider know about all the medicines and supplements you are using before you start breastfeeding.
- About other prescription and nonprescription medicines, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Amoxicillin/clavulanate potassium may affect the way other medicines or products work, and other medicines or products may affect how amoxicillin/clavulanate potassium work. Ask your health care provider if there are interactions between amoxicillin/clavulanate potassium and the other medicines you or your child take.
