What are the risks of aspirin?
Risks of Low-Dose Aspirin. Like most medicines, aspirin has side effects. It irritates your stomach lining and can trigger gastrointestinal upset, ulcers and bleeding. And, because it thins your blood, it can be dangerous for people who are at higher risk of bleeding. Factors that make preventive use of aspirin dangerous include:
How much aspirin should you take if you suspect a stroke?
With patients that suffered ischemic stroke, doctors may prescribe a daily, low-dose aspirin to help prevent another blood clot in the brain. The dose will vary based on your unique health risk factors. Low doses can range between 75-150 mg while some patients are prescribed a regular strength tablet up to 325mg.
What is the immediate treatment for a possible stroke?
An IV injection of recombinant tissue plasminogen activator (TPA) — also called alteplase (Activase) or tenecteplase (TNKase) — is the gold standard treatment for ischemic stroke. An injection of TPA is usually given through a vein in the arm within the first three hours.
How does aspirin provide immediate benefit for stroke patients?
Aspirin works as a blood thinner, helping to prevent the further formation of stroke-causing clots. Early treatment is especially important because the likelihood of a recurrent stroke is highest immediately following an initial stroke.

Rather than the 15% overall reduction in longer-term risk reported previously in these trials, aspirin reduced the early risk of a fatal or disabling stroke by about 70-80% over the first few days and weeks.
How long after TIA can you get a stroke?
Lead researcher Professor Peter Rothwell, a stroke expert from the University of Oxford, explained: ‘The risk of a major stroke is very high immediately after a TIA or a minor stroke (about 1000 times higher than the background rate), but only for a few days.
Is aspirin good for TIA?

How many patients received 162 mg of aspirin?
Information on immediate aspirin dose and short-term outcomes was available for 48 422 patients (86%). An immediate aspirin dose of 162 mg was given to 36 594 patients (75.6%). Patients from GUSTO I were more likely to receive 162 mg, whereas patients from GUSTO III were more likely to receive 325 mg. Baseline characteristics according to aspirin dose are presented in Table 1. It is evident that there were some imbalances between the groups. Patients receiving 162 mg were more frequently enrolled from North America, more likely to be current smokers and diabetic, less likely to have a family history of cardiac disease or history of MI, and more likely to have an inferior MI than those receiving 325 mg. Treatment and procedural characteristics are depicted in Table 2. Patients who received 162 mg were more likely to receive streptokinase; were less likely to receive tenectaplase and reteplase; had significantly higher measured activated partial thromboplastin times at 6, 12, and 24 hours; and were more likely to undergo invasive procedures. In-hospital medications also were significantly different between the groups ( Table 2 ).
Is 325 mg aspirin safe?
Although these data are nonrandomized, they suggest that for the first dose of aspirin, 162 mg may be as effective as and safer than 325 mg for the acute treatment of STEMI.
Is aspirin randomized?
There are several limitations to our study. First, our study was a post hoc analysis of prospectively collected data within the context of 2 clinical trials. As such , the dose of aspirin was not prescribed by the study protocol, nor was it randomized. In general, treatment effects cannot be reliably estimated by observational studies, even when good adjustment models are available. However, the data with respect to both efficacy and safety are mechanistically consistent. Second, we could not explore the indications for a specific aspirin dose. Nevertheless, the main determinant of the dose used in patients in GUSTO I and GUSTO III was the routine approach of centers and specific countries ( Table 1 ). This argues against the possibility that the selection of dose may be related to the risk profile of patients, thus confounding the differences in efficacy or safety between dose groups. Third, trial differences and regional differences in patient populations and practice patterns are reflected by significant differences in the baseline characteristics of the patients ( Table 1) and in additional treatments. However, after adjustment for these differences, including the use of fibrinolytics and other antithrombotics, and stratification by clinical trial and region, a dose response between aspirin and bleeding complications is still observed. Fourth, it was unknown whether the patient was on aspirin before the infarction. Finally, GUSTO I and III were performed 10 to 15 years ago, before clopidogrel and glycoprotein IIb/IIIa use, which may limit the generalizability of the results. Nevertheless, with the current use of dual and triple antiplatelet therapy in STEMI, great focus remains on minimizing bleeding risk.
Does aspirin cause bleeding?
The major risk of aspirin therapy is the risk of bleeding, and there is considerable evidence that the side effects of aspirin are dose dependent. 3,8,38,39 A UK study group found that patients with higher aspirin dose were more likely to have both gastrointestinal tract symptoms and gastrointestinal hemorrhage. 28 In the Dutch TIA trial, 27 risk of bleeding was higher in patients receiving 283 mg compared with those receiving 30 mg. Observational data from the Clopidogrel in Unstable Angina to Prevent Recurrent Events (CURE) investigators 40 noted increased bleeding risks with increasing aspirin dose (<100 mg, 1.9%; 101 to 199 mg, 2.8%; >200 mg, 3.7%; P =0.0001). In a recent analysis of 31 randomized controlled trials, major, minor, gastrointestinal, and fatal bleeding all increased with increased aspirin dose. 41
Does aspirin inhibit platelet cyclooxygenase 1?
Aspirin irreversibly inhibits platelet cyclooxygenase-1, thereby preventing the conversion of arach idonic acid to pro staglandin H 2, which, under normal circumstances, is then converted to thromboxane (TX) A 2 and other bioactive prostanoids. 21 TXA 2 is synthesized and released by platelets and acts as a platelet aggregator and vasoconstrictor. 22 By preventing TXA 2 formation, aspirin irreversibly blocks platelet function. At higher doses, aspirin suppresses vascular endothelial cell production of prostacyclin, 23 which, if unopposed, results in inhibition of platelet aggregation and induces vasodilation.
What is the best medicine for a stroke?
If you get to the hospital within 3 hours of the first symptoms of an ischemic stroke, you may get a type of medicine called a thrombolytic (a “clot-busting” drug) to break up blood clots. Tissue plasminogen activator (tPA) is a thrombolytic. tPA improves the chances of recovering from a stroke.
