Ondansetron
ONDANSETRON
Overview:
Ondansetron is a medicine used to prevent and treat nausea and vomiting caused by chemotherapy, radiation, surgery, or stomach problems.
It is available in tablets, syrups, and injections.
Classification:5-HT₃ (serotonin) receptor antagonist
Uses:
Ondansetron is prescribed to prevent and manage nausea and vomiting linked to chemotherapy, radiation therapy, post-surgical recovery, and stomach infections such as gastroenteritis. It can also be administered for pregnancy-related vomiting, but only under medical supervision. This drug is particularly beneficial when nausea is intense or when other treatments are ineffective.
How it works:
Ondansetron functions by inhibiting serotonin (5-HT₃) receptors located in both the brain and the digestive system.
Serotonin is a substance that can initiate the vomiting response.
By obstructing these receptors, ondansetron aids in preventing and alleviating nausea and vomiting, particularly those induced by chemotherapy, surgical procedures, or gastrointestinal illnesses.
Dosage:
As prescribed by your doctor.
Side effects:
Headache
Constipation
Dizziness
Tiredness or fatigue
Dry mouth
Precautions:
Before initiating Ondansetron treatment, it is crucial to inform your healthcare provider if you have any liver diseases, heart conditions, or a history of irregular heart rhythms. This medication requires careful use in individuals with low levels of potassium or magnesium in their blood. It is advisable to avoid taking it in conjunction with other medications that may impact heart rhythm. Pregnant or breastfeeding women should only use Ondansetron if it is explicitly prescribed by a doctor. Always follow the prescribed dosage and avoid using it for mild or occasional nausea without consulting a healthcare professional.
