If insomnia persists for more than 5 days, it is necessary to consult a doctor regarding the appropriateness of further use of the drug.
Do not administer the medicine to children under 15 years of age.
The first signs of acute poisoning are drowsiness and signs of anticholinergic effects: agitation, dilated pupils, accommodation paralysis, dry mouth, redness of the face and neck, hyperthermia, sinus tachycardia. Delirium, hallucinations, and athetosis are more common in children; sometimes they are harbingers of seizures – rare complications of severe poisoning. Even if seizures do not occur, acute doxylamine poisoning sometimes causes rhabdomyolysis, which can be complicated by acute renal failure. This muscle disorder is common and requires systematic screening by measuring creatine phosphokinase activity.
Treatment is symptomatic. At an early start of treatment, it is recommended to use activated carbon (50 g for adults, 1 g / kg for children).

Allergic reactions are possible, including skin rash, itching.
