Hypnos® is a hypnosis medicinal product of the ethanolamine class from the group of histamine H1 receptor blockers, has a sedative and M-anticholinergic effect. Reduces the time to fall asleep, increases the duration and quality of sleep.
Cmax in blood plasma concentration is achieved 2 hours after administration. The plasma half-life is on average 10 hours.
Doxylamine succinate undergoes biotransformation in the liver. Doxylamine succinate is partially metabolized in the liver by demethylation and N-acetylation. The half-life can be significantly increased in elderly patients or in patients with renal or hepatic insufficiency. The various metabolites formed during the breakdown of the molecule are not quantitatively significant, as 60% of the applied dose is found in the urine in the form of unchanged doxylamine.
Periodic and transient insomnia in adults.
Hypersensitivity to any components of the medicinal product or to other antihistamine medicinal products; angle-closure glaucoma in the patient's history or in the family history; difficult urination (diseases of the urethra and prostate).
Interaction with other medicinal products and other forms of interaction.
Alcohol enhances the sedative effect of most H1-antihistamines. Drinking alcoholic beverages and using medicines containing ethanol should be avoided.
The following combinations of Hypnos® should be considered:
- atropine and atropine-like medicinal products (imipramine antidepressants, anticholinergic antiparkinsonian medicinal products, atropine antispasmodics, disopyramide, phenothiazine neuroleptics) due to the occurrence of side effects such as urinary retention, constipation, dry mouth;
- other antidepressants that affect the central nervous system (morphine derivatives) (pain relievers used to treat cough and substitution therapy), neuroleptics, barbiturates, benzodiazepines, anxiolytics, except benzodiazepines, sedative antidepressants, (amitriptyline, doxepin, mianserin, mirtazapine, trimipramine) sedative H1-antihistamines; antihypertensive drugs of central action; others: baclofen, pizotifen, thalidomide, due to increased suppression.
Special warnings and precautions for use.
Insomnia can have a variety of causes that do not require medication, so it is recommended to consult a doctor before using the medicinal product.
Like all hypnotics or sedatives, doxylamine succinate can exacerbate sleep apnea syndrome (an increase in the number and duration of respiratory arrest).
H1-antihistamines should be used with caution in elderly patients due to the risk of dizziness, which may increase the risk of falls (e.g. when people get up at night) with consequences that are often serious for this category of patients.
To prevent drowsiness during the day, it must be remembered that the duration of sleep after using the medicinal product should be at least 7 hours.
Alcohol intake should be avoided when using the medicinal product.
Important information about excipients.
The medicinal product contains lactose, therefore patients with rare hereditary forms of galactose intolerance, lactase deficiency or glucose-galactose malabsorption syndrome cannot use it.
The medicinal product contains sodium, so patients on a sodium-controlled diet should be careful when using it.
Fertility, pregnancy and lactation.

Effects on ability to drive and use machines.

For oral administration. Apply 15-30 minutes before bedtime.
The recommended dose is 7.5–15 mg per day (½ – 1 tablet per day). If necessary, the dose can be increased to 30 mg per day (2 tablets per day).

The medicinal product is not recommended for use in children under the age of 18 years.
The first signs of acute poisoning are drowsiness and manifestations of anticholinergic effects: agitation, dilation of the pupils, accommodation paralysis, dry mouth, redness of the face and neck, hyperthermia, sinus tachycardia. Delirium, hallucinations and atheotic movements are more often observed 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, requiring regular systematic screening by measuring creatine phosphokinase activity.
Activated charcoal intake (50 g for adults and 1 g/kg for children), if necessary, carry out symptomatic treatment. According to the indications, anticonvulsants and artificial lung ventilation are prescribed.
In the morning after the evening intake of the medicinal product, there may be a slowdown in reactions and dizziness, therefore, to prevent falling, it is necessary to avoid sudden movements. Anticholinergic effects rarely develop: constipation, dry mouth, accommodation disorders, palpitations, urinary retention.
Daytime sleepiness: at development of such effect it is necessary to reduce a dose.
Allergic reactions are possible, including skin rashes, itching.
