Every 40 seconds, someone in the United States experiences a stroke. When a stroke strikes, knowing what medicine is given for a stroke immediately is critical, but the specific treatment depends entirely on the type of stroke a person is having and how quickly they receive medical attention.

Up to 2 million brain cells die each minute during a stroke, making rapid treatment essential. Understanding **what emergency medicine is given after a stroke** is crucial, as the medications and treatment approach differ significantly based on the type of stroke a person has experienced.

According to the American Heart Association, symptomatic intracranial hemorrhage occurs in a small but significant percentage of patients treated with intravenous tPA for acute ischemic stroke. This serious risk, along with other critical complications and contraindications, is precisely **why you would stop tPA** or not start it in the first place, with clinical decisions based on a careful weighing of the potential benefits and harms.

Bleeding is the most common and feared complication of fibrinolytic therapy, with intracranial hemorrhage occurring in up to 1% of patients. Knowing **when you can not give fibrinolytic therapy** is critical for patient safety and preventing life-threatening adverse events.

According to the American Heart Association, every 30-minute delay in initiating thrombolytic therapy for ischemic stroke significantly worsens patient outcomes. Understanding how soon should thrombolytic therapy be given is vital, as these clot-busting drugs must be administered within narrow, indication-specific timeframes to maximize effectiveness while minimizing the risk of life-threatening side effects.

Patients who arrive at an emergency room within 3 hours of their first stroke symptoms often have less disability three months later [1.7.7]. A critical factor in improving outcomes is understanding what the time window for IV thrombolysis is and acting quickly.

Every minute of an untreated stroke can result in the loss of nearly 2 million brain cells, a sobering statistic that underpins the critical urgency of treatment. For patients with an ischemic stroke, the clot-busting drug tissue plasminogen activator (tPA) is a primary treatment, but it is strictly governed by a time limit. This critical deadline is a pharmacological balancing act between restoring blood flow and avoiding a potentially catastrophic complication.

Studies show that for every 15-minute reduction in door-to-needle time for intravenous tPA, the risk of in-hospital death and symptomatic intracranial hemorrhage decreases. This emphasizes why 4.5 hours for tPA represents a critical, evidence-based deadline for treating ischemic stroke.

Despite being a primary treatment for acute ischemic stroke, over 80% of patients do not receive tPA. This often depends on a complex evaluation of the patient's condition, with many factors dictating why someone would not get tPA. The decision process involves weighing the potential benefits of dissolving a blood clot against the significant risk of inducing a life-threatening hemorrhage.

According to the American Heart Association and American Stroke Association guidelines, one of the most critical exclusion criteria for alteplase (tissue plasminogen activator, tPA) is any sign of a current intracranial hemorrhage. This medication is a powerful thrombolytic, and its administration is based on a careful and rapid risk-benefit analysis, making it essential to identify what condition would exclude a patient from receiving alteplase before treatment.
