Aspirin and Fondaparinux Sodium

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Using fondaparinux together with aspirin may increase the risk of bleeding, including severe and sometimes fatal hemorrhage. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. You should seek immediate medical attention if you experience any unusual bleeding or bruising, or have other signs and symptoms of bleeding such as dizziness; lightheadedness; red or black, tarry stools; coughing up or vomiting fresh or dried blood that looks like coffee grounds; severe headache; and weakness. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

GENERALLY AVOID: In patients receiving neuraxial anesthesia or spinal puncture, the risk of developing an epidural or spinal hematoma during LMWH, heparinoid, or fondaparinux therapy may be increased by the concomitant use of other drugs that affect coagulation, including nonsteroidal anti-inflammatory drugs (NSAIDs). The development of epidural and spinal hematoma can lead to long-term or permanent paralysis.

GENERALLY AVOID: Theoretically, NSAIDs may potentiate the risk of bleeding complications associated with the use of fondaparinux. NSAIDs interfere with platelet adhesion and aggregation and may prolong bleeding time in healthy individuals. While these effects are generally slight and of relatively short duration with most NSAIDs (except aspirin) at recommended dosages, they may be of pronounced clinical significance when combined with the inhibitory effects of fondaparinux on the clotting cascade. In addition, NSAIDs are known to cause dose-related gastrointestinal bleeding, which may be complicated by anticoagulant therapy.

MANAGEMENT: Products containing NSAIDs, especially if given chronically or in high dosages, should preferably be discontinued prior to initiation of fondaparinux therapy. Close clinical and laboratory observation for bleeding complications is recommended if concurrent therapy is necessary. In patients undergoing neuraxial intervention, coadministration of these agents should be approached with caution and only after thorough assessment of risks and benefits. Besides bleeding complications, patients should also be monitored frequently for signs and symptoms of neurologic impairment such as midline back pain, sensory and motor deficits (numbness or weakness in lower limbs), and bowel or bladder dysfunction.
