transient sleep disturbances.
Method of use, course and dosage:
Inside. 1/2-1 tabb./day, flush with a small amount of liquid, 15-30 minutes before sleep. If the treatment is ineffective, the dose may be increased to 2 tabs on the doctor's recommendation.
Duration of treatment from 2 to 5 days; if insomnia persists, you should see a doctor.
Kidney and liver failure patients: Due to evidence of increased plasma concentration and decreased plasma clearance of doxylamine, a downward dose correction is recommended.
Elderly patients over 65: histamine H1 receptor blockers should be carefully prescribed to this group of patients due to possible dizziness and delayed reactions with a risk of falling (for example, during night waking after taking sleeping pills). In view of evidence of increased plasma concentration, decreased plasma clearance and increased T1/2, a downward dose correction is recommended.
Symptoms: daytime drowsiness, arousal, pupil dilation (midriasis), accommodation disorders, dry mouth, redness of the face and neck skin (hyperemia), fever (hyperthermia), sinus tachycardia, disorder of consciousness, hallucinations, decreased mood, anxiety, violation of coordination of movements, tremors (tremors), involuntary movements (atetosis), convulsions (epileptic syndrome), coma. Involuntary movements are sometimes a harbinger of seizures, which can indicate a severe poisoning. Even in the absence of cramps, severe doxylamine poisoning can cause the development of rhabdomyolysis, which is often accompanied by acute renal failure. In such cases, standard therapy with constant control of CFC level is shown.
If you have symptoms of poisoning, you should immediately consult a doctor.
Treatment: symptomatic (m-cholinometics, etc.), the first aid is indicated by activated carbon (50 g for adults and 1 g/kg for children).

When taken simultaneously with m-choline-blocking agents (atropine, imipramine antidepressants, antiparkinsonian drugs Donormyl, atropine spasmolytics, disopiramide, phenothiazine neuroleptics), the risk of side effects such as delayed urine, constipation, dry mouth increases.
Since alcohol increases the sedative effect of most histamine H1 receptor blockers, including Donormyl, it is necessary to avoid it at the same time
