Check with your doctor or pharmacist if you are not sure. Shake the bottle well before measuring the dose. A measuring device is provided to ensure accuracy. If in children aged from 6 months and in adolescents this medicinal product is required for more than 3 days, or if symptoms worsen a doctor should be consulted.
For infants aged 3 - 5 months medical advice should be sought if symptoms worsen or not later than 24 hours if symptoms persist. This medicine should NOT be given if your child weighs less than 5 kg. The usual daily dose in children is 20 - 30 mg per kg of bodyweight in divided doses. Leave at least 4 hours between doses.
For oral and short term use only. Do not give more than 30 mls mg in any 24 hours. Not more than 2 doses should be given in 24 hours. If fever is not reduced, consult a doctor. Never give a double dose to make up for the missed dose. The symptoms can include nausea, stomach pain, vomiting may be blood streaked , headache, ringing in the ears, confusion and shaky eye movement.
At high doses, drowsiness, chest pain, palpitations, loss of consciousness, convulsions mainly in children , weakness and dizziness, blood in urine, cold body feeling, and breathing problems have been reported. When three-fourths of the initial volume of acetylcysteine solution has been nebulized, a quantity of Sterile Water for Injection, USP approximately equal to the volume of solution remaining should be added to the nebulizer.
This obviates any concentration of the agent in the residual solvent remaining after prolonged nebulization. The physical and chemical compatibility of acetylcysteine solutions with certain other drugs that might be concomitantly administered by nebulization, direct instillation, or topical application, has been studied. Acetylcysteine should not be mixed with certain antibiotics. For example, the antibiotics tetracycline hydrochloride, oxytetracycline hydrochloride and erythromycin lactobionate were found to be incompatible when mixed in the same solution.
These agents may be administered from separate solutions if administration of these agents is desirable. The supplying of these data should not be interpreted as a recommendation for combining acetylcysteine with other drugs. The table is not presented as positive assurance that no incompatibility will be present, since these data are based only on short-term compatibility studies done in the Mead Johnson Research Center. Manufacturers may change their formulations, and this could alter compatibilities.
These data are intended to serve only as a guide for predicting compounding problems. If it is deemed advisable to prepare an admixture, it should be administered as soon as possible after preparation.
Do not store unused mixtures. Do not await results of assays for acetaminophen level before initiating treatment with acetylcysteine solution. The following procedures are recommended: The stomach should be emptied promptly by lavage or by inducing emesis with syrup of ipecac.
Syrup of ipecac should be given in a dose of 15 mL for children up to age 12 and 30 mL for adolescents and adults followed immediately by drinking copious quantities of water. The dose should be repeated if emesis does not occur in 20 minutes. In the case of a mixed drug overdose, activated charcoal may be indicated. However, if activated charcoal has been administered, lavage before administering acetylcysteine treatment. Activated charcoal adsorbs acetylcysteine in vitro and may do so in patients and thereby may reduce its effectiveness.
Administer the loading dose of acetylcysteine, mg per kg of body weight. Prepare acetylcysteine for oral administration as described in the specific Dosage Guide and Preparation table. Determine the subsequent action based on predetoxification plasma acetaminophen information.
Choose ONE of the following four courses of therapy. Predetoxification plasma acetaminophen level is clearly in toxic range See Acetaminophen Assays — Interpretation and Methodology below: The maintenance dose is then repeated at 4-hour intervals for a total of 17 doses.
Monitor hepatic and renal function and electrolytes throughout the detoxification process. Predetoxification acetominophen level could not be obtained: Proceed as in A. Predetoxification acetominophen level is clearly in the nontoxic range beneath the dashed line on the nomogram and you know that acetominophen overdose occurred at least 4 hours before the predetoxification acetaminophen plasma assays: Discontinue administration of acetylcysteine.
Predetoxification acetominophen level was in the nontoxic range, but time of ingestion was unknown or less than 4 hours. Because the level of acetaminophen at the time of the predetoxification assay may not be a peak value peak may not be achieved before 4 hours post-ingestion , obtain a second plasma level in order to decide wether or not the full dose detoxification treatment is necessary.
If the patient vomits any oral dose within 1 hour of administration, repeat that dose. In the occasional instances where the patient is persistently unable to retain the orally administered acetylcysteine, the antidote may be administered by duodenal intubation. Preparation of Acetylcysteine Solution for Oral Administration: If administered via gastric tube or Miller-Abbott tube, water may be used as the diluent. The dilutions should be freshly prepared and utilized within one hour.
Remaining undiluted solutions in opened vials can be stored in the refrigerator up to 96 hours. Acetaminophen Assays — Interpretation and Methodology: However, the reported history of the quantity of a drug ingested as an overdose is often inaccurate and is not a reliable guide to therapy of the overdose. Interpretation of Acetaminophen Assays: When results of the plasma acetaminophen assay are available refer to the nomogram below to determine if plasma concentration is in the potentially toxic range.
Do not wait for assay results to begin acetylcysteine treatment. If the predetoxification plasma level is above the broken line, continue with maintenance doses of acetylcysteine. If the predetoxification plasma level is below the broken line described above, there is minimal risk of hepatic toxicity and acetylcysteine treatment can be discontinued. Assay procedures most suitable for determining acetaminophen concentrations utilize high pressure liquid chromatography HPLC or gas liquid chromatography GLC.
The assay should measure only parent acetaminophen and not conjugated. The assay procedures listed below fulfill this requirement: Supportive Treatment of Acetaminophen Overdosage: Maintain fluid and electrolyte balance based on clinical evaluation of state of hydration and serum electrolytes.
Treat as necessary for hypoglycemia. Administer vitamin K1 if prothrombin time ratio exceeds 1. Diuretics and forced diuresis should be avoided. The loading dose is mg per kilogram of body weight.
Do not decrease the proportion of diluent. Estimating Potential for Hepatotoxicity: The following nomogram has been developed to estimate the probability that plasma levels in relation to intervals post-ingestion will result in hepatotoxicity.
Plasma or Serum Acetaminophen Concentration vs. There are no contraindications to oral administration of acetylcysteine in the treatment of acetaminophen overdose. The latter increases with increasing purulence owing to the presence of cellular debris.
The mucolytic action of acetylcysteine is related to the sulfhydryl group in the molecule. The mucolytic activity of acetylcysteine is unaltered by the presence of DNA, and increases with increasing pH. Significant mucolysis occurs between pH 7 and 9. Antidotal Acetaminophen is rapidly absorbed from the upper gastrointestinal tract with peak plasma levels occurring between 30 and 60 minutes after therapeutic doses and usually within 4 hours following an overdose.
The parent compound, which is nontoxic, is extensively metabolized in the liver to form principally the sulfate and glucuronide conjugates which are also nontoxic and are rapidly excreted in the urine. A small fraction of an ingested dose is metabolized in the liver by the cytochrome P mixed function oxidase enzyme system to form a reactive, potentially toxic, intermediate metabolite which preferentially conjugates with hepatic glutathione to form the nontoxic cysteine and mercapturic acid derivatives which are then excreted by the kidney.
Therapeutic doses of acetaminophen do not saturate the glucuronide and sulfate conjugation pathways and do not result in the formation of sufficient reactive metabolite to deplete glutathione stores. The increased formation of reactive metabolite may deplete the hepatic stores of glutathione with subsequent binding of the metabolite to protein molecules within the hepatocyte resulting in cellular necrosis.
Acetylcysteine has been shown to reduce the extent of liver injury following acetaminophen overdose. Its effectiveness depends on early oral administration, with benefit seen principally in patients treated within 16 hours of the overdose. Acetylcysteine probably protects the liver by maintaining or restoring the glutathione levels, or by acting as an alternate substrate for conjugation with, and thus detoxification of, the reactive metabolite.
Acetylcysteine was found to be nonteratogenic under the conditions of the study. No teratogenic effects were observed among the offspring. Teratology and a perinatal and postnatal toxicity study in rats were performed with a combination of acetylcysteine and isoproterenol administered by the inhalation route.
In the rat, two groups of 25 pregnant females each were exposed to the aerosol for 30 and 35 minutes, respectively, twice a day from the 6th through the 15th day of gestation. In the pregnant rat 30 rats per group , twice-daily exposure to an aerosol of acetylcysteine and isoproterenol for 30 or 35 minutes from the 15th day of gestation through the 21st day postpartum was without adverse effect on dams or newborns.
If the predetoxification plasma level is above the broken line, continue with maintenance doses of acetylcysteine. The supplying of these data should not 200mg interpreted as a recommendation for combining acetylcysteine with other drugs. Acetylcysteine Solution, 200mg tylenol in ml, USP does not contain an antimicrobial agent, and care must be taken to minimize contamination of the sterile solution, 200mg tylenol in ml. Do not decrease the proportion of diluent. If fever is not reduced, consult a doctor. Do not exceed the recommended dose or duration of treatment, 200mg tylenol in ml. Reports of irritation to the tracheal and bronchial tracts have been received and although hemoptysis has occurred in patients receiving acetylcysteine such findings are not uncommon in patients with bronchopulmonary disease and 200mg causal relationship has not been established. Acetylcysteine solution may be administered using conventional nebulizers tylenol of plastic or glass. Do not store unused mixtures. Speak to your doctor or pharmacist before taking if you are tylenol to get pregnant. When three-fourths of the initial volume of acetylcysteine solution has been nebulized, 200mg tylenol in ml, a quantity of Sterile Water for Injection, USP 200mg equal to the volume of solution remaining should be added to the nebulizer. A acyclovir canada order device is provided to ensure accuracy. Under certain conditions, a color change may occur in acetylcysteine in the opened bottle. No teratogenic effects were observed among the offspring. Assay procedures most suitable for determining acetaminophen concentrations utilize high pressure liquid chromatography HPLC or gas liquid chromatography Tylenol.
