Zofran ultimately takes 30 minutes to work. It is used to prevent nausea from radiation and cancer medicines. It must be taken by mouth 1 or 2 hours before one goes into treatment. 

Only one or two months of regular use, then after that, one will need to take proton pump inhibitors (PPIs) like Prilosec for the rest of one’s life. This is because continual use leads to decreased production of stomach acid, which leads to ulcers and “tiny holes in the intestinal lining.”

Zofran takes a while to work because it’s been designed not to take immediate effect but rather to slowly reduce nausea by altering body chemistry. In other words, Zofran can take from 20-30 minutes for maximum effectiveness after it’s been swallowed.

Zofran works gradually to decrease nausea by altering various bodily functions smoothly. The drug will not start working immediately (generally up to twenty or thirty minutes) and will stay effective for 8 hours.

When people experience nausea, it’s usually in response to bodily fluid output or smelling solid odors. Additionally, it happens when the body needs energy, and the stomach gets empty. Long-term abdominal pain can also lead to weight loss and feeling nauseous.

If the Zofran is not working within the stipulated time, the reason could be because of several reasons: Zofran is not working correctly; Zofran might be having adverse reactions with other medication that one recently started. 

There may be another underlying cause for nausea (such as IBS). The person might need a higher dosage. They may need to change methods (e.g., oral medications vs. suppository) to get relief.

The actions of Zofran are dependent on three variables: dosage, drug distribution, and the pharmacokinetics of the drug. These all come into play when considering how long it will take for Zofran to affect an individual patient.

Though it may seem like taking more pills would increase efficacy quicker, too high of a dose can prove not only ineffective but harmful. Make sure to consult the physician before upping one’s dosage or changing dosages.
