Individuals taking clavulanate potassium tablets should continue with the drug if it only causes vomiting, diarrhea or nausea, explains WebMD. However, the patient should notify the doctor if any of the symptoms persist. A patient should immediately tell the doctor if he experiences unusual tiredness, passes dark urine or develops new signs of infection such as fever or persistent sore throat.
Individuals allergic to cephalosporin or penicillin may also be allergic to clavulanate potassium tablets, explains Drugs.com. Doctors may have to adjust the dosage for those who have mononucleosis, kidney disease or liver disease. The drug may not cause harm to unborn babies, but it can pass into breast milk and cause diarrhea, allergic reactions or yeast infection in nursing babies. Amoxicillin and clavulanate potassium tablets may reduce the efficiency of birth control pills, explains RxList.
An overdose of clavulanate may cause abdominal pain, diarrhea, cloudy urine or a reduced amount of urine, according to Drugs.com. The body may adjust to the medicine with time and the side effects may disappear, in which case the patient requires no medical attention. However, patients should notify the doctor if rare symptoms such as sleeplessness, hyperventilation or dry mouth occur when taking the medication.
