Gemcitabine (Gemzar®)

Gemcitabine

Brand Name: Gemzar®

Gemcitabine is used to treat cancers of the ovary, pancreas, lung, and breast.

Gemcitabine belongs to a class of drugs known as antimetabolites, and resembles a normal cell nutrient that cancer cells need to grow. Because of this resemblance, cancer cells “ingest” gemcitabine, which then interferes with their growth.

This medication is given as an injection into a vein (intravenously). Usually, gemcitabine is given once weekly for several weeks. Each injection takes about 30 minutes to complete. The duration of treatment may depend on several factors, including the type of cancer being treated, how well the drug is working, and your ability to tolerate the medication. Your doctor will recommend the dose and schedule that is best for you.

Gemcitabine side effects

To prevent problematic interactions between gemcitabine and other drugs, be sure to tell your doctor if you are allergic to any medications, and what other medications and supplements you are currently taking. You should also inform your doctor if you have or ever had a liver tumor, liver disease, or kidney disease, if you are pregnant or planning to become pregnant, or if you are breastfeeding. Gemcitabine should not be taken during breastfeeding. You should not receive a live vaccine while taking gemcitabine, or be exposed to someone who has recently received a live vaccine. In general, it’s best to avoid being near anyone who is sick or has an infection.

Possible side effects may include:

  • Mild nausea, vomiting, or upset stomach
  • Diarrhea
  • Constipation
  • Swelling in hands, feet, or ankles
  • Skin rash
  • Numbness or tingly sensation
  • Drowsiness
  • Hair loss

Some of gemcitabine’s side effects can be serious. Call your doctor immediately if you experience any of these symptoms:

  • Pale skin
  • Unusual bruising or bleeding
  • Unusual weakness
  • Decreased or nonexistent urination
  • Yellowing of the eyes
  • Nausea, upper stomach pain, loss of appetite
  • Clay-colored stools
  • Chest pain or heaviness
  • Sudden numbness or weakness, especially on one side of body
  • Sore throat, fever, chills, or other signs of infection
  • Pain, swelling, or skin changes where needle was inserted
  • Blood in urine
  • Hearing problems
  • Mouth sores or white patches
  • Breathing problems

Please note that this is not a comprehensive list. Patients may experience additional effects not mentioned above.

At Cancer Treatment Centers of America (CTCA), your team of cancer experts will explain each of the side effects of gemcitabine with you in detail, as well as the side effects and expectations of all other medications planned as part of your individualized treatment plan.
