The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

This medication falls into category D. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. There is a possibility that Gemzar can cause harm to the unborn baby when given to a pregnant woman.

Tell your doctor if you are breastfeeding or plan to breastfeed. It is not known if Gemzar is excreted in human breast milk or if it will harm your nursing baby.

Gemzar is given intravenously (IV) usually at your doctor's office or clinic.

The medication is given through an IV, usually over a period of approximately 30 minutes.

• 3-Week Schedule
  • Depending on the type of cancer being treated, Gemzar is usually given on days 1 and 8 of each 21-day cycle.
• 4-Week Schedule
  • Gemzar may also be given on days 1, 8, and 15 of each 28-day cycle.
  • Often another cancer drug is given in combination with Gemzar.

The Gemzar dose your doctor recommends will be based on the following:

• the cancer you have
• other medical conditions you have
• other medications you are taking
• how you respond to this medication
• your weight
• your height

Pancreatic Cancer

Gemzar is usually administered by a healthcare provider in a medical setting making it unlikely for an overdose to occur. However, the dose is calculated based on body surface area, which is calculated using height and weight. Thus, too much of the drug could be given if a miscalculation is made.

Symptoms of an Gemzar overdose are difficult to predict as there have been few reports of overdose. It is possible an overdose may result in an increased risk of the usual Gemzar side effects. This may include bone marrow suppression, paresthesias (tingling, burning, pricking, or numbness of skin), and severe rash.

Keep all of your doctor and laboratory appointments.
