FDA Issues Warning About Lamictal
The FDA recently warned that Lamictal (lamotrigine), frequently used for treating seizures and bipolar disorder, can cause a rare but serious immune system reaction called hemophagocytic lymphohistiocytosis (HLH), which can be life-threatening. HLH typically presents as a persistent fever, usually greater than 101° F, and can lead to severe problems with blood cells and vital organs. Health care professionals should be aware that prompt recognition and early treatment are important for improving HLH outcomes and decreasing mortality. Diagnosis is often complicated because early signs and symptoms, such as rash and fever, are not specific. HLH also may be confused with other serious immune-related adverse reactions such as drug reaction with eosinophilia and systemic symptoms (DRESS). The FDA is requiring a change to the drug’s prescribing information and drug labeling.
Is Tenecteplase Better Than Alteplase Before Thrombectomy?
When administered before thrombectomy, tenecteplase is associated with a higher incidence of reperfusion and better functional outcome than alteplase among patients with ischemic stroke treated within 4.5 hours after symptom onset, according to a study published April 26 in the New England Journal of Medicine. Researchers randomly assigned patients with ischemic stroke and occlusion of the internal carotid, basilar, or middle cerebral artery who were eligible for thrombectomy to receive tenecteplase or alteplase within 4.5 hours after symptom onset. The primary outcome was reperfusion of greater than 50% of the involved ischemic territory or an absence of retrievable thrombus at the initial angiographic assessment. Of 202 patients enrolled, 101 were assigned to receive tenecteplase. The primary outcome occurred in 22% of the tenecteplase group and 10% of the alteplase group.
