Timentin (ticarcillin disodium and clavulanate potassium) is a combination of a penicillin antibiotic and a form of clavulanic acid, similar to penicillin, used to treat many different infections caused by bacteria, such as urinary tract infections, bone and joint infections, severe vaginal infections, stomach infections, and skin infections. Common side effects of Timentin include:

  • mild diarrhea
  • gas
  • stomach pain
  • nausea
  • vomiting
  • joint or muscle pain
  • headache
  • skin rash or itching
  • injection site reactions (pain, swelling, or burning)
  • vaginal yeast infection (itching or discharge)

Tell your doctor if you experience serious side effects of Timentin including:

  • watery or bloody diarrhea
  • blood in your urine
  • feeling an urgent need to urinate
  • painful or difficult urination
  • easy bruising or bleeding
  • unusual weakness
  • dry mouth
  • increased thirst
  • confusion
  • increased urination
  • muscle pain or weakness
  • fast heart rate
  • lightheadedness
  • fainting
  • fever
  • chills
  • body aches
  • flu symptoms: fever, sore throat, and headache with a severe blistering, peeling, and red skin rash
  • chest pain
  • seizures (convulsions)

The recommended adult dosage for systemic and urinary tract infections is 3.1 grams of Timentin given every 4 to 6 hours. Pediatric dose is based on the child's weight. Other drugs may interact with Timentin. Tell your doctor all prescription and over-the-counter medications you use. Tell your doctor if you are pregnant or plan to become pregnant during treatment with Timentin. Timentin can make birth control pills less effective. Use a second non-hormone method of birth control (such as a condom, diaphragm, spermicide) while using this drug. It is unknown if this medication passes into breast milk or if it could harm a nursing baby. Consult your doctor before breastfeeding.
