ondansetron onset of action

Ondansetron is a selective 5-HT3 receptor antagonist. While its mechanism of action has not been fully characterized, ondansetron is not a dopamine-receptor antagonist. Serotonin receptors of the 5-HT3 type are present both peripherally on vagal nerve terminals and centrally in the chemoreceptor trigger zone of the area postrema. It is not certain whether ondansetron’s antiemetic action is mediated centrally, peripherally, or in both sites.

Ondansetron is used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy and surgery. Ondansetron is in a class of medications called 5-HT3 receptor antagonists. It works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting. it is also known as Zofran. ginger helps too.

That is the generic name for zofran.

Ondansetron is the generic for Zofran. Why would you refuse it? It's safe to take or your Dr wouldn't prescribe it to you. There's other meds out there if you don't want to take it. My Dr gave me Diclegis. It helped take the edge off the nausea.

It is in a class of medications called 5-HT3 receptor antagonists and works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting. I just got a bottle of 30 Ondansetron on Medicare for $5. There are also other similar meds you can take so you should find a solution and not have to deal with what you have been. Call your doctor tomorrow and get a script sent to your pharmacy. It should work immediately if you are taking a high enough dosage.

Ondansetron has been assigned to pregnancy category B by the FDA. Animal studies failed to reveal evidence of fetal damage. There are no controlled data in human pregnancy. Case reports have described two women who have received ondansetron during pregnancy for life-threatening hyperemesis gravidarum. No abnormalities were noted in the offspring of these two women. Ondansetron is only recommended for use during pregnancy when benefit outweighs risk.

Zofran tablets, syrup and injection all contain the active ingredient ondansetron hydrochloride dihydrate, which is a type of medicine called a 5HT3 antagonist. (NB. Ondansetron is also available without a brand name, ie as the generic medicine.) Ondansetron is used to prevent and treat nausea and vomiting that can be caused by chemotherapy or radiotherapy treatment for cancer, or by surgery. Vomiting is controlled by an area of the brain called the vomiting centre.

I'm only 7 weeks 3 days. I'm on folic acid and asked about oother supplements that i could take as I'm always so exhausted and doctor said to early to take anything eelse. However that visit was prior to the onset of this nausea. Will visit doc as I'm worried embryo may not be getting sufficient nutrients as I'm not eating. I will ask about the b6.

m interested in hearing from anybody who has had similar symptoms, or a similar course of action before getting a diagnosis. I have never really heard of tinnitis or vertigo being symptoms of MS, and those are the main reasons I even started pursuing medical help to begin with. The doctors have ruled out some explanations (like the acoustic neuroma), but there are still other possibilities on the table (Meniere's disease, or even high blood pressure for example).

It kind of sounds like a form of Action tremors, but I have to agree with mkh9.

Zofran (ondansetron) is used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy, and surgery. Ondansetron is in a class of medications called serotonin 5-HT3 receptor antagonists. It works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting. ----------------------------------------------------------------------------------- Effexor Why is this medication prescribed? Effexor (venlafaxine) is used to treat depression.

The onset of action ranges from 45 minutes - 1 ½ hours, and the duration of action is six hours. Diazepam carries a bi-phasic half-life of 20-50 hours (for Diazepam), and 30-200 hours (for Desmethyldiazepam). Valium is indicated for the long-term management of generalized anxiety and tension-anxiety. Tolerance will not develop to the anxiolytic property of Diazepam, although tolerance will develop to the sedative/hypnotic property.

A partial µ-opioid receptor agonist, its mixed agonist/antagonist activity affords it a lower risk of dependence and abuse than full µ agonists like morphine. Meptazinol exhibits not only a short onset of action, but also a shorter duration of action relative to other opioids such as morphine, pentazocine, or buprenorphine.

All I know is they do not prescribe it to one indivodual in large quantities and that bc it can affect and stay in your blood for so long they have to monitor how much an individual gets. Like if youve used it the last 6 months, ondansetron is one of two or three prescribed pills that eliminate you as a donor for plasma, blood, or other things.

I was put on 50 mg of zoloft a month ago and have had nausea ever since. It seems like it's been getting worse over the last couple of weeks. Yesterday I was prescribed Ondansetron ODT 4mg. It doesn't seem to help. Will the nausea go away?

What is the onset of action after taking a dose of the immunoglobulin.

I have recently spent some time looking into the functioning of different antacids. After some considerable amount of reading, I have come to the conclusion that one of the best of this group of medications is Prilosec (omeprazole). I did once give this drug a poor rating, but recent evidence suggests it's actually proving to be one of the safest and most effective.

And yes Nexium as Pepela suggested is also in the PPI class

A 2006 double-blind, randomized controlled trial indicated that ondansetron may have value in the treatment of schizophrenia, as an adjunct to haloperidol.

I almost feel guilty for complaining but I need some sort of relief if possible. Did anything work for any of you? What about that constant bitter taste all the time? Please share your remedies/stories with me. Thanks.
