Monitor patients closely for at least 60 minutes after administration of Lymphazurin 1% ( 5.1 ). The admixture of Lymphazurin 1% with local anesthetics results in an immediate precipitation of 4-9% drug complex. Use a separate syringe for anesthetics ( 5.2 ). Lymphazurin 1% interferes with measurements in peripheral blood pulse oximetry. Arterial blood gas analysis may be needed ( 5.3 ). 5.1 Hypersensitivity Reactions Life-threatening anaphylactic reactions (respiratory distress, shock, angioedema) have occurred after Lymphazurin 1% administration. Reactions are more likely to occur in patients with a history of bronchial asthma, allergies, drug reactions or previous reactions to triphenylmethane dyes. Monitor patients closely for at least 60 minutes after administration of Lymphazurin 1%. Trained personnel should be available to administer emergency care including resuscitation. 5.2 Precipitation of Lymphazurin 1% by Lidocaine The admixture of Lymphazurin 1% (with local anesthetics (i.e. lidocaine)) in the same syringe results in an immediate precipitation of 4 – 9% drug complex. Use a separate syringe to administer a local anesthetic. 5.3 Interference with Oxygen Saturation and Methemoglobin Measurements Lymphazurin 1% interferes with measurements of oxygen saturation in peripheral blood by pulse oximetry and can cause falsely low readings. The interference effect is maximal at 30 minutes and minimal generally by four hours after administration. Arterial blood gas analysis may be needed to verify decreased arterial partial pressure of oxygen. Lymphazurin 1% may also cause falsely elevated readings of methemoglobin by arterial blood gas analyzer. Therefore, co-oximetry may be needed to verify methemoglobin level."]}
