Question 1

can a one time dose of iv zofran cause side effects after 14 hours?

Accepted Answer

Zofran: Pharmacological studies on Zofran show that patients with moderate to severe hepatic impairment (liver) may have an extended half life of Zofran. In most patients over half the drug is gone in 5.7 hours. Older patients may take longer to clear Zofran as well. It really depends what side effects you are talking about as well.

Question 2

i took 4mg of zofran (ondansetron) around 2 am. then took 6 mg around 7 am for naseau. is this dose ok for adult 120lb?

Accepted Answer

Yes, it is OK: The recommended adult oral dosage of Zofran (ondansetron) is 24 mg given as three 8-mg tablets or 4-8 mg 3X/day as needed. Not to exceed 24mg in 24 hours. It is always prudent to discuss side effects and risks with your physician.
Good luck.

Question 3

articles says zofran (ondansetron) is not safe during pregnancy. i'm 4 weeks and i was given a dose by iv. dont plan on getting it anymore. should i be worried?

Accepted Answer

No: Zofran (ondansetron) is typically used safely during pregnancy.  You shouldn't worry.  Docs are very cautious about medication used during pregnancy so you needn't worry.

Question 4

can a one time dose of iv zofran cause serotonin syndrome? after 16 hours?

Accepted Answer

Can't say for sure.: People have developed serotonin syndrome with use of Zofran. Although we usually think of serotonin syndrome as occurring with very high doses of seritonergic medications (often taken over a period of time &amp; with mulitple meds) - the bottom line is that some people can develop serotonin syndrome on a mildly seroternergic medication, at low dose with brief use.

Question 5

experiencing constipation after taking zofran (ondansetron) what laxative would be recommended to relieve this ?

Accepted Answer

maybe none: I suggest you avoid chemicals if possible.Eat a balanced diet, move a bit, and stay hydrated. If you must use something, keep in simple. Milk of magnesia, (magnesium hydroxide) as directed, should work on someone who's not already taking it . Good luck.

Question 6

hi. will zofran odt not work properly if swallowed whole? still having some nausea after my most recent dose i accidentally swallowed?

Accepted Answer

Usually: The oral dissolving feature is just a quicker way for many to get it into their bloodstream by having some absorbed under the tongue. The total dose would remain the same. The effectiveness might change some from a delay in absorption.

Question 7

taking zofran (ondansetron) odt for nausea. doc said i could double 4mg tablets. i took 2 tablets 4 hours ago is it okay take another dose?

Accepted Answer

Maybe: In general, zofran (ondansetron) is made for short-term usage, and if it has not gotten your symptoms under control yet, adding more is unlikely to help. If, however, it was helping and has worn off, taking one additional tablet would be okay. Again, in the short-term.
Keep in mind zofran (ondansetron) is an opiate relative, which means if you have a drug or alcohol history or a family history, it is not your best choice.

Question 8

is zofran (ondansetron) 4mg safe if you have a healthy heart? how long after stopping the drug (i took one dose) does the risk for cardiac issues cease?

Accepted Answer

Ondansetron: Zofran (ondansetron) in doses greater than 16 mg at a time has been implicated in prolonging the qt interval.  This effect would last for a few hours while the drug was in the system.  A single 4 mg dose does not carry this risk.

Question 9

i have been having stomach episodes for the last four years about 10 times a year. it comes with no warning, starts with montazumas revenge, then i vomit nonstop even when taking the max dose of zofran  and promethizine. i also  get horrible pain close to

Accepted Answer

This : This could represent diverticulitis which is inflammation of an outpouching along the colon wall.  A colonoscopy may help with the diagnosis.  Typical treatment is with antibiotics.  Suregery is reserved for recurrent or complicated cases.

Question 10

i have a cough, bad nausea and fever. my doc gave me zofran (ondansetron) 4mg 3x day. 4 isn't enough anymore can i double the dose or is that not safe?

Accepted Answer

Need doctor's advice: Never alter the total dose, duration, frequency of daily use, nor start/stop a prescription drug without your doctor's advice. There is room to adjust zofran (ondansetron) here, but what are you treating? More importantly, what condition has worsened in you that warrants more zofran (ondansetron)? Ask your doctor to find the cause, not just treat your symptoms.
