Symptoms (due to paracetamol)
In case of an overdose of paracetamol, hepatic insufficiency may develop, which may lead to the need for liver transplantation or death.
Hepatotoxic effect in adults is manifested when taking paracetamol in an amount of 10 g or more. In the presence of factors that affect the toxicity of paracetamol for the liver (see the sections on "Interaction with other drugs", "Special instructions"), liver damage can occur after taking paracetamol in an amount of 5 g or more.
With prolonged use of the drug beyond the recommended dose, the drug may have nephrotoxic effects (renal colic, nonspecific bacteriuria, interstitial nephritis, papillary necrosis).
During the first 24 hours after an overdose, the following symptoms may appear: nausea, vomiting, stomach pain, pale skin, anorexia, metabolic acidosis. After 1-2 days, signs of liver damage are determined (soreness in the liver, increased activity of "liver" enzymes),it is possible to develop a violation of carbohydrate metabolism and metabolic acidosis.
In severe cases of overdose, as a result of liver failure, encephalopathy (a violation of brain function), bleeding, hypoglycemia, cerebral edema, up to a lethal outcome, the need for liver transplantation, death may develop. It is also possible to develop acute renal failure with acute tubular necrosis, the characteristic signs of which are pain in the lumbar region, hematuria (blood or erythrocyte in the urine), proteinuria (high protein in the urine), with severe liver damage may be absent. There were cases of heart rhythm disturbances, pancreatitis.
Treatment
In case of suspicion of an overdose of Solpadein Fast, even in the absence of pronounced first symptoms, it is necessary to stop using the drug and immediately consult a doctor for medical assistance. During the first hour after an overdose, but no later than 4 hours, gastric lavage and intake of enterosorbents (Activated carbon, polyphepan).It is necessary to determine the concentration of paracetamol in the blood plasma, but not earlier than 4 hours after an overdose (earlier results are not reliable).
Introduction of acetylcysteine within 24 hours after an overdose. The maximum protective effect is achieved within the first 8 hours after an overdose, with time the effectiveness of the antidote drops sharply. If necessary, enter acetylcysteine intravenously. If there is no vomiting before the patient enters the hospital, methionine may be used. The need for additional therapeutic measures (methionine intake, intravenous acetylcysteine) is determined depending on the concentration of paracetamol in the blood plasma, as well as on the time elapsed after its administration. Treatment of patients with severe impairment of liver function 24 hours after taking paracetamol should be done in conjunction with specialists from the toxicology center or specialized department of liver diseases.
Symptoms (due to caffeine)
Pain in epigastrium, vomiting, frequent urination, tachycardia, arrhythmia, CNS stimulation (insomnia, anxiety, agitation, anxiety, increased neural reflex excitability, tremors and convulsions).It should be borne in mind that the appearance of clinically significant symptoms of caffeine overdose when taking the drug is always associated with severe liver damage against a background of paracetamol overdose.
Treatment
There is no specific antidote. Treatment includes supportive activities, such as copious drinking and maintaining vital signs. For 1 hour to 4 hours after an overdose, it is recommended to take activated charcoal. To reduce the effect of caffeine on the functions of the central nervous system, it is recommended that intravenous and beta-adrenoceptor antagonists be administered to reduce the cardiotoxic effect.
