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.

Description

  • Highly-emetogenic chemotherapy
  • Moderately emetogenic chemotherapy
  • Radiotherapy, including total body irradiation, single high-dose abdominal fraction, or daily abdominal fractions
  • Postoperative

The generic name for Zofran is Ondansetron.

  • Highly emetogenic chemotherapy: 24-mg dose given 30 minutes before receiving chemotherapy.
  • Moderately emetogenic chemotherapy: 8-mg dose given 30 minutes before receiving chemotherapy. Another 8-mg dose is given 8 hours after the first dose, then 8 mg every 12 hours for 1 to 2 days after chemotherapy.

Ingredients

The active ingredient in Zofran is Ondansetron.

Contraindications

Be sure you speak to your doctor about your allergies. Do not take Zofran if you are allergic to ondansetron or any of the ingredients in Zofran.

Do not take Zofran with apomorphine.

Cautions

  • Some medications may interact with Zofran if taken together. Tell your doctor if you take any other medications, including prescription, over-the-counter, herbal supplement, and vitamins.
  • Stop Zofran immediately if you develop an allergic reaction, including anaphylaxis and bronchospasm. Seek medical care right away if you have a rash, hives or swelling, trouble breathing, tightness of the throat, or a fast heartbeat.
  • Do not take Zofran if you have congenital long QT syndrome. The risk for QT prolongation and Torsades de Pointes is increased if you take Zofran with other medications that can prolong the QT interval and should be monitored with electrocardiograms. You should also be monitored if you have certain electrolyte abnormalities, heart failure, or arrhythmias. 
  • Zofran may increase your risk for serotonin syndrome, especially if taken with other serotonergic medications. Serotonin syndrome can be life-threatening. Seek medical care right away if you experience agitation, confusion, dilated pupils, high blood pressure, fast heart rate, rigid muscles, diarrhea, headache, shivers, loss of muscle coordination or twitching muscles, sweating, goosebumps, fever, or seizures.
  • Zofran may mask progressive ileus or gastric distention in patients who have had abdominal surgery or chemotherapy-induced nausea and vomiting. Monitor for decreased bowel activity, especially in patients who have risk factors for gastrointestinal obstruction.
  • Phenylketonuric patients should be cautioned that Zofran ODT (orally disintegrating tablets) contain phenylalanine.
  • Tell your doctor if you are pregnant or plan to become pregnant. Consider the benefits versus risks.
  • Tell your doctor if you are breastfeeding or plan to breastfeed. The benefits versus risks should be considered.

Side Effects

Zofran may cause side effects. Tell your doctor if you experience severe adverse effects or side effects that are bothersome or won't go away. Common Zofran side effects may include:
