Ondansetron is the non-proprietary name for an antiemetic medication used to help alleviate nausea and vomiting in patients undergoing chemotherapy, radiotherapy, or following surgery. It may also be used in other scenarios where nausea or vomiting are issues, though it's not effective in all such cases; the medication little effect on motion sickness, for example.

In medical settings Ondansetron can be administered in patients as young as 1 month old, and parents can buy Ondansetron for administration to children age 4 and up. Explicit doctor approval is advisable before the medication is administered to any patient under age 12, and dosage adjustments may be necessary.

Patients typically buy Ondansetron under its brand name Zofran, in a number of formulas:

• Regular tablets
• Orally-dissolving tablets
• Oral solution
• Injections

To some extent which formula is used is a matter of personal preference. Orally-dissolving tablets and oral solution are ideal for patients unable or unwilling to swallow regular tablets. Injections are generally reserved for use in a medical setting.

Dosage & Administration

With the exception of injections, it's generally only possible to buy Ondansetron in 4 mg or 8 mg doses. It's rare that children below 12 years old are prescribed more than 4 mg doses; patients 12 years and up may be advised to take 8, 16, or 24 mg doses.

Taking multiple tablets or orally-dissolving tablets together provides the same benefit as taking a single high-dose tablet; for example, two 4 mg tablets is the same as one 8 mg tablet, two 8 mg tablets is the same as one 16 mg tablet, and so forth. There is no need to buy Ondansetron in 16 or 24 mg doses.

Standard treatment ranges from a single dose taken once to multiple doses taken twice per day (12 hours apart) for 5 or 6 consecutive days. For other conditions the medication treats---such as cyclic vomiting syndrome or gastroenteritis---treatment may vary considerably; doctor instructions should be followed.

For adults undergoing chemotherapy or radiotherapy:

• Take 8 mg one to two hours prior to treatment.
• Take another 8 mg 12 hours after.
• Continue taking 8 mg every 12 hours for up to 5 more days, if needed.

In some cases Ondansetron makes a difference but doesn't provide sufficient relief. In these cases the patient may try 16 mg or 24 mg doses instead of 8 mg. Do not exceed 48 mg (24 mg twice) per day.

For children under age 12 undergoing chemotherapy or radiotherapy:

• Take 4 mg one to two hours prior to treatment.
• Take another 4 mg 12 hours after.
• Continue taking 4 mg every 12 hours for up to 5 more days, if needed.

It is exceptionally rare that child doses will be increased beyond 4 mg, and this should be done only with doctor approval.

Adults undergoing surgery:

• Take 16 mg one to two hours prior to surgery.
• Additional doses are often not needed, but if they are another 16 mg can be taken 12 hours later.

For surgery, children below 12 years of age are usually administered Zofran in an injection by a healthcare worker.

In rare cases Ondansetron does little for chemotherapy, radiotherapy, and post-surgical nausea/vomiting, in which case a doctor can recommend alternative treatments. As mentioned above this product doesn't work on all nausea, such as motion sickness---try to be sure it is suitable for a given condition before buying Ondansetron.

Precautions & Side Effects

Ondansetron is well-tolerated, with common side effects being very mild. They include:

Before buying Ondansetron patients should be aware that it is associated with prolonged QT intervals, again particularly at higher doses.
