Side Effects of Clamoxyl

Clamoxyl is a combination drug consisting of the penicillin antibiotic amoxicillin and a beta-lactamase inhibitor called clavulanic acid, according to Glaxo Smith-Kline, the drug's manufacturer. Clamoxyl is used to treat certain types of bacterial infections of the lungs, skin, bladder, sinuses and ears. According to MedLinePlus, certain sexually transmitted diseases may also be treated with combination amoxicillin and clavulanic acid.

Gastrointestinal Upset

According to MedlinePlus, the most common gastrointestinal side effects experienced by people taking amoxicillin and clavulanic acid include diarrhea, vomiting and upset stomach. Antibiotic medications target many different types of bacteria, including those that are normally found in the gastrointestinal tract. As a result, antibiotics frequently cause minor stomach upset due to a change in the dynamics of the digestive tract.

Yeast Infection

The skin, mucosal membranes and bowel of the human body are populated by a variety of microorganisms, including bacteria and the yeast Candida albicans, explains the text "Infection Microbiology and Management." Under normal conditions, these microorganisms must compete for resources; this controls the growth of the population. When antibiotic treatment is given, bacteria that are normally found in and on the body are killed off, allowing other types of microorganisms such as yeast to take over. Thrush is a yeast infection of the mucous membranes of the mouth; women may experience vaginal yeast infections.

Mild Skin Rash

According to the text "Infection Microbiology and Management," some antibiotics cause mild skin rashes because of immune system hypersensitivity to some component of the medication. This is similar to a normal allergic reaction of the skin. In rare cases, patients experience rashes that are severe and even life-threatening. MayoClinic.com explains that Stevens-Johnson syndrome is a condition that results in layers of skin dying and falling off; it is caused by severe hypersensitivity to a drug.

Treating Side Effects

MedlinePlus explains that diarrhea can be treated by consuming yogurt with live bacterial cultures. This will help to re-populate the intestinal tract's supply of beneficial digestive bacteria. Probiotic supplements containing live bacterial cultures are also available at many drug and health food stores. Use of these supplements may help to aid in the prevention of yeast infections and/or gastrointestinal upset.
