Mild reactions such as flush, urticaria, fever and nausea occur rarely. These reactions normally disappear rapidly when the infusion rate is slowed down or the infusion is stopped. Very rarely, severe reactions such as shock may occur. In these cases, the infusion should be stopped and appropriate treatment should be initiated.
Post-marketing experience: Additional side effects reported spontaneously include rigors, hypertension, hypotension, feeling cold, tachycardia, tremor, bronchospasm, dyspnoea, chest tightness, stridor and dizziness.
