Onin Oral Solution belongs to a group of medications called ' antiemetics,' primarily used in the prevention of vomiting (being sick) and nausea (feeling sick) that usually occur after cancer chemotherapy, radiation treatment, or surgery. Nausea is an uneasy feeling in which a person feels an urge to vomit, while vomiting is the natural response of the body to expel the stomach contents from the mouth forcefully.

Onin Oral Solution contains Ondanestron, which works by blocking the action of a chemical in the body (serotonin) responsible for causing nausea and vomiting. As a result, Onin Oral Solution prevents the sensation of nausea and vomiting caused by conditions like surgery, cancer chemotherapy, pregnancy, or motion sickness.

Take Onin Oral Solution exactly as prescribed. Your doctor will advise you on how often you take Onin Oral Solution based on your medical condition. You may experience common side effects such as constipation, headache, diarrhea, drowsiness, flushing (a feeling of warmth), weakness, and tiredness. However, not every person experiences these side effects, and some of the unpleasant effects of Onin Oral Solution do not require medical attention. If the side effects persist or worsen, please consult your doctor.

Onin Oral Solution is an anti-emetic medication primarily used to prevent and treat nausea and vomiting associated with conditions such as cancer chemotherapy, radiation treatment, and surgery. When serotonin levels increase in the blood, it stimulates the CTZ receptor (chemoreceptor trigger zone) located in the brain responsible for controlling nausea and vomiting. Onin Oral Solution contains Ondansetron, which works by inhibiting the release of serotonin, thereby preventing nausea and vomiting.

Do not use Onin Oral Solution if you are allergic to any of its ingredients. Avoid using Onin Oral Solution if you are taking apomorphine (a medicine used to treat Parkinson's disease), as it may cause a sharp drop in blood pressure and even fainting. Inform your doctor before using Onin Oral Solution if you have any medical conditions, such as severe constipation, bowel obstruction, depression, electrolyte imbalance, heart or blood vessel problems (such as irregular heartbeats and high blood pressure), diabetes, liver problems, or a history of tonsils or adenoid removal surgery. Tell your doctor if you are taking any medications for depression, as using them alongside Onin Oral Solution may increase the risk of serotonin syndrome, a potentially life-threatening condition. Onin Oral Solution is not recommended for use during early pregnancy (first trimester), as it may increase the risk of birth defects in the mouth and face of the baby. Avoid breastfeeding while taking Onin Oral Solution, as small amounts of the medicine may pass into breast milk. Avoid consuming alcohol while taking Onin Oral Solution, as it may worsen the side effects like drowsiness.
