What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

  • Product Details


    Zuplenz is a prescription antiemetic medication that prevents nausea and vomiting when a patient is undergoing chemotherapy, radiation treatments, or post-op following a surgery. Ondansetron is the active ingredient in Zuplenz and it works to block a serotonin from the brain that causes nausea and vomiting. The medication is taken differently depending on if it is to prevent nausea and vomiting from chemotherapy or it is to do the same for radiation therapy. If it is taken to prevent nausea after surgery, it needs to be taken one (1) hour before the surgery.

    You can buy Zuplenz with a doctor’s prescription at our local pharmacy, but your lowest Zuplenz cost will be when your order medication online from Canada Pharmacy.

    Tell your doctor if you have any history of irregular heartbeat, liver, stomach, or intestinal problems before beginning on Zuplenz.

    Ondansetron can cause a heart condition called QT prolongation that affects heart rhythm and is potentially serious. Tell your doctor of all medications you are currently taking and if you have any history of heart failure, slow heartbeat, QT prolongation in EKG, or cardiac arrest. Low levels of potassium can contribute to QT prolongation.
