[adverse reactions]

Generally used for antipyretic analgesic dose of rare adverse reactions. A large number of long-term medication (such as the treatment of rheumatic fever), especially when the blood drug concentration > 200 u g / ml is easy to appear adverse reactions. Higher blood drug concentration, adverse reactions more obvious.

1. More common are nausea, vomiting, abdominal discomfort or pain (due to the product of the gastric mucosa induced by direct stimulation) gastrointestinal reaction (rate of 3% ~ 9%), after discontinuation of the drug may disappear. Long-term or high-dose use may have gastrointestinal bleeding or ulceration.

2 central nervous: the emergence of reversible tinnitus, hearing loss, more than taking a certain course of treatment, blood concentrations of 200 to 300 g/L after the emergence.

3. Allergic reactions: appeared in 0.2% of the patients, asthma, urticaria, angioedema or shock. For susceptible, medication rapidly after the onset of dyspnea, severe cases can cause death, said aspirin asthma. Some aspirin allergy, asthma and nasal polypus triad, often with genetic and environmental factors about.

4 liver, renal function damage, and dose related, especially the dose of the ambassador blood drug concentration of 250 g/ml is easy to occur. The damage is reversible, after stopping the drug can be recovered, but there is a report of renal papillary necrosis.

These adverse reactions may be associated with or without warning symptoms, regardless of whether the patient has a history of gastrointestinal adverse reactions or serious gastrointestinal events in history a previous history of gastrointestinal disease. (ulcerative colitis, Crohn's disease) patients should be cautious about the use of non steroidal anti-inflammatory drugs, so as not to make the condition worse. When patients taking the drug or ulcer gastrointestinal bleeding, the drug should be discontinued. Elderly patients using non steroidal anti-inflammatory drug adverse reactions increase the frequency of especially the gastrointestinal hemorrhage and perforation, the risk may be fatal.

4. For a variety of COX-2 selective or nonselective NSAIDs drug sustained time of 3 years of clinical trials showed, this product may cause serious adverse cardiovascular thrombotic events and increase the risk of myocardial infarction and stroke, the risk may be fatal.

9 diagnosis of interference:

(1) the long-term daily consumption than 2.4G, copper sulfate glycosuria test can appear false positive. Enzyme glucose urine test can be false negative.

(2) interference uabt;

(3) when the blood drug concentration is more than 130 g/ml, the serum uric acid can be determined by the colorimetric method, but the law of uric acid can not be affected;

(4) the determination of urinary 5- () - hydroxy - () - acid - acid (5-HIAA) by fluorescence method can be interfered by this product;

(5) the determination of urinary vanilla based almond acid (VMA), the results can be high and low due to the different methods used;

(6) due to the inhibition of platelet aggregation, the bleeding time can be prolonged. The dose of small to 40mg/ days can also affect the function of platelets, but there is no small dose (150mg/ days) to cause bleeding in the report;

(7) liver function test, when the blood drug concentration > 250 g / ml, alanine amino transferase, aspartate amino transfer enzymes and serum alkaline phosphatase had abnormal changes, dose reduction can be returned to normal;

(9) daily dosage of more than 5g of serum cholesterol is low;

(10) due to the effect of this product on the renal tubule, the potassium excretion increased, which could lead to the decrease of serum potassium;

(11) the use of a large dose of this product, the use of radioimmunoassay in serum levels of thyroid hormone (T4) and three thyroid hormone (T3) can be a lower result;

(12) due to the goods and phenolsulfonphthalein in the renal tubular competitive excretion, and phenolsulfonphthalein excretion decreased (PSP excretion test)

The following 10 conditions should be used with caution:

(1) with asthma and other allergic reactions;

(2) glucose -6- phosphate dehydrogenase deficient (this product occasionally cause hemolytic anemia);

(3) gout (this product can affect the effect of other urinary acid drugs, small doses may cause uric acid retention);

(5) heart failure or high blood pressure, a large number of drugs may cause heart failure or pulmonary edema;

(6) there is an increased risk of renal toxicity in renal insufficiency;

(7) thrombocytopenia.

11 in a long period of time a large number of drugs should be regularly checked red blood cell pressure, liver function and serum levels of salicylic acid.
