To neutralize enalapril antidote exists. Treatment is aimed at restoring water-salt balance and eliminate the symptoms.

Hydration therapy is conducted with the aim of restoring electrolyte and water in the body. To do this, intravenously administered solution of sodium chloride 0,9% (saline) glucose 5%.

Symptomatic treatment of overdose enalapril:

  • to support the work of the heart – cardiac glycosides;

  • nausea and heartburn – antacids;
  • to maintain the pancreas – pancreatic enzymes;
  • to eliminate pain – antispasmodics;
  • for the prevention and treatment of bacterial kidney infection – antibiotics;
  • in allergic skin lesions – antihistamines, hormonal ointments.

If the kidney damage, inflammation and violation of functionality shown hemodialysis – blood purification through the apparatus from toxic substances and saturation of useful microelements.

In severe cases such as stroke, anaphylactic shock, heart attack attack carried out resuscitation.

Do not take enalapril, spirits, immunosuppressants and cytostatics (chemotherapy). These drugs work synergistically with each other and can cause symptoms of poisoning.
