The safety of the drug in children is not clear.

- dyspepsia digestive tract.
How dangerous is inderal? When a large overdose of the drug inhibits the heart and lungs. The consequences of such effects may jeopardize the person's life.
Signs of severe poisoning:
- arrhythmia – a violation of cardiac contractions;
- ventricular arrhythmia – disruption of the heart, associated with the violation of the contractions of the ventricles;
- the aggravation of symptoms of chronic heart failure;
- violation of peripheral blood circulation;
- bronchospasm, shortness of breath, may stop breathing;
- cold of the lower extremities due to a decrease in venous pressure;
- a critical drop in blood pressure below 80/50;
- collapse, loss of consciousness.
In case of overdose average weight decreases hepatic blood flow, a release of insulin by the pancreas, decreases the minute and stroke volume of the heart. The agent has cardiotoxicity (affect the state of cardiocyte cells of the heart). The drug depresses the Central nervous system, has cardiodepressivne action.
In high concentrations it causes ventricular fibrillation, an attack of dyspnoea – a violation of the depth and frequency of breathing. There is a sharp drop in blood pressure,cardiac arrest and death.
In pregnant inderal delay of intrauterine growth of the child. So the drug is not prescribed to women awaiting the birth of a child.
First aid in acute poisoning
If the moment the man swallowed the pill, it took less than 45 min, you must immediately induce vomiting.
Algorithm of actions:
- Give the victim drink 1 liter of cool water for 2-5 minutes.
- Pushing down on the tongue with two fingers, to cause a gag reflex and cause vomiting.
- To give a sorbent – the activated coal from calculation 1 tablet on 1 kg of body weight. Once to drink 5 tablets.
- The patient lay, cover with a warm blanket, feet put a hot water bottle.
- If the patient's condition is satisfactory, you can give him to drink warm sweet tea.
If low blood pressure, the victim must be in the Trendelenburg posture is to lie on your back under hips to put a pillow or folded blanket so that the lower torso was above the head at 45°.
In severe poisoning anaprilin the patient must be transported to the hospital for emergency care.
In violation of the conduction of cardiac electrical impulses administered atropine intravenously. It blocks the vagus nerve, relaxes muscles, stimulates the respiratory center.
If the use of atropine was not effective, resort to the use of a pacemaker.
When ventricular extrasystole – an untimely contraction of individual heart chambers (ventricles), used lidocaine. When overdose of lidocaine, immediately consult a doctor.
If not pulmonary or renal edema, use, intravenous plasma-substituting solutions. They support the functioning of the internal organs in severe pathological conditions.
If replacement therapy is not having the desired effect, prescribe one of the drugs: epinephrine, dopamine, dobutamine. They stimulate the heart, narrowing of the lumen of blood vessels, raise HELL.
In heart failure, shown diuretics, cardiac glycosides, glucagon.
In convulsions intravenous diazepam decreases the excitation of the brain, increases the resistance of nerve cells to oxygen deficiency, relieves emotional stress.
When spasm of the bronchi used inhaled or intravenous beta-agonists – isoprenaline, dobutamine. They relax the smooth muscles, eliminate spasms. They also increase the strength and frequency of contractions of the heart.
If the person is unconscious, carry out resuscitation: artificial oxygen supply, continuous monitoring of the heart and kidneys, and supportive care.
Inderal is a potent drug with serious side effects. The use of this medication requires a responsible approach to treatment, strict adherence to the dosage of the drug.
