Zartan Oral

Generic Name: CEPHALEXIN - ORAL
Pronounced: (sef-a-LEX-in)

Zartan Oral Side Effects

Diarrhea, dizziness, headache, or stomach upset may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these unlikely but serious side effects occur:

  • mental/mood changes (e.g., agitation, confusion)


Tell your doctor immediately if any of these rare but very serious side effects occur:

  • severe stomach/abdominal pain
  • persistent nausea/vomiting
  • yellowing eyes/skin
  • dark urine
  • change in the amount of urine
  • new signs of infection (e.g., fever, persistent sore throat)
  • easy bruising/bleeding


This medication may rarely cause a severe intestinal condition (pseudomembranous colitis) due to a resistant bacteria. This condition may occur during treatment or weeks to months after treatment has stopped. Tell your doctor immediately if you develop persistent diarrhea, abdominal or stomach pain/cramping, blood/mucus in your stool. Do not use anti-diarrhea products or narcotic pain medications if you have any of these symptoms because these products may make them worse.

Use of this medication for prolonged or repeated periods may result in oral thrush or a new vaginal yeast infection. Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge, or other new symptoms.

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including:

  • rash
  • itching/swelling (especially of the face/tongue/throat)
  • severe dizziness
  • trouble breathing


This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
