Can Zofran affect BP?
Zofran interactions The combination can cause serious side effects such as loss of consciousness, heart arrhythmias (QT prolongation), and dangerously low blood pressure (hypotension).
Can ondansetron cause hypotension?
Recent studies suggest that ondansetron, a commonly used antiemetic, also affects hypotension.
What effect can ondansetron have on the heart?
Ondansetron may increase the risk of developing abnormal changes in the electrical activity of the heart, which can result in a potentially fatal abnormal heart rhythm. Used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy and surgery.
How does Zofran prevent hypotension?
Ondansetron by blocking Bezold–Jarisch reflex (BJR) through inhibition of serotonin receptors has been effective in the prevention of post-spinal hypotension, and bradycardia. Bradycardia frequently accompanies post-induction hypotension in elderly patients, which signifies a possible preventing role for ondansetron.
Can ondansetron cause heart palpitations?
Zofran may cause headaches, drowsiness, constipation and other mild side effects. In rare cases, the anti-nausea medication can cause erratic heartbeats and high serotonin levels, which may be life-threatening.
Can Zofran cause hypertension?
Dilated pupils. Nausea, vomiting and diarrhea. Fast heartbeat and high blood pressure.
Does Zofran increase heart rate?
Irregular heart rhythms may develop in patients taking Zofran. According to the drug’s label, reported arrhythmias have included heartbeats that are too fast (tachycardia) or too slow (bradycardia) or that are too fast and originate from the wrong part of the heart (ventricular and supraventricular tachycardia).
Does Zofran cause bradycardia?
What causes Bezold reflex?
This cardiac reflex is characterized by hypotension, bradycardia, and peripheral vasodilation (see Chapter 10). The Bezold-Jarisch reflex occurs in response to noxious stimuli detected in the ventricle; historically this was studied using Veratrum alkaloids administered intravenously.
Can ondansetron cause atrial fibrillation?
Ondansetron is known to cause myocardial infarction, ventricular tachycardia, ventricular fibrillation, AF, sinus bradycardia, ventricular bigeminy, ST segment depression, and coronary vasospasm in susceptible patients.
Can Zofran make your heart race?
Can ondansetron worsen depression?
Ondansetron (16 microg/kg twice daily) showed greater therapeutic efficacy at alleviating symptoms of overall mood disturbance, fatigue, vigor, confusion/bewilderment, and depression among EOA compared with LOA. EOA-associated improvements in mood disturbance seemed to be independent of drinking behavior.
What is the reflex tachycardia?
If blood pressure decreases, the heart beats faster in an attempt to raise it. This is called reflex tachycardia. This can happen in response to a decrease in blood volume (through dehydration or bleeding), or an unexpected change in blood flow.

Does ondansetron reduce blood pressure after spinal anesthesia in the elderly?

Is there a generic for ondansetron hydrochloride?
In patients where nausea and/or vomiting must be avoided postoperatively, ondansetron hydrochloride tablets are recommended even where the incidence of postoperative nausea and/or vomiting is low. Ondansetron is available in generic form. Common side effects of ondansetron include: headache,
