Precautionary measures:

It should be particularly careful with arterial hypotension (systolic blood pressure below 100 mm Hg) in situations characterized by instability indicators of systemic hemodynamics (acute myocardial infarction, multiple trauma, starting shock) in patients with a history of violations of peripheral blood (eg, treated with cytostatic agents) or hypersensitivity reactions to drugs (food preservatives, fur, hair dye), suffering from bronchial asthma and / or chronic infectious-inflammatory respiratory tract diseases with hypersensitivity to any of NSAIDs and analgesics, antipyretics (threat the development of asthma and shock) in infants of the first 3 months of life or weighing less than 5 kg (increased risk of renal dysfunction). Do not combine with drugs that cause intolerance reactions (X-ray contrast agents, plasma substituting solutions, penicillins). The sudden worsening of the patient’s general condition (fever, inflammation of the oral mucous membranes of the nose and throat, increased erythrocyte sedimentation rate), you must immediately stop taking. In the case of anaphylactic shock is required to enter in / (slowly) 0.1% epinephrine solution (if necessary – again with intervals of 15-30 min), then – a glucocorticoid, antihistamines, hold replacement of blood volume, ventilation, cardiac massage.

Special instructions:

You can not mix in the same syringe with other. Drugs. Excretion in the urine of one of the biotransformation products can cause red coloration of urine (clinical significance and does not disappear after the cancellation).
