Alcohol consumption should be avoided during treatment.
If you are over 65 years old, you may be more susceptible to experiencing side effects.
Normodorm can exacerbate dehydration and heat stroke symptoms due to decreased sweating.
Inform your doctor or pharmacist if you are using, have recently used, or may need to use any other medication.
Do not take normodorm with the following medications, as their effects may be enhanced:

Adults (over 18 years old)
The recommended dose is 1 tablet (25 mg) per day.
If daytime drowsiness occurs, it is recommended to reduce the dose to half a tablet (12.5 mg) per day or take it earlier to ensure that at least 8 hours pass until wake-up time.
Do not take more than 1 tablet (25 mg) per day.
Use in adults over 65 years old
Adults over 65 years old are more prone to suffering from other conditions that may recommend a dose reduction. If unwanted side effects occur, it is recommended to reduce the dose to half a tablet (12.5 mg) per day.
Use in patients with liver or kidney disease
These patients should take a different dose, adjusted to the degree of their disease, which will be determined by the doctor.
Use in children and adolescents
Normodorm is not recommended for use in children under 18 years old, so the medication should not be used in this population.
Route and method of administration
Oral route.
The tablet can be divided into equal doses.
Tablets should be taken 30 minutes before bedtime with a sufficient amount of liquid (preferably water).
Duration of treatment
The duration of treatment should be as short as possible. In general, the duration of treatment can range from a few days to a week.
It should not be administered for a period exceeding 7 days without consulting a doctor.
Symptoms of an overdose are: drowsiness, depression or stimulation of the central nervous system, anticholinergic effects (dilated pupils, fever, dry mouth, decreased intestinal tone), flushing, increased or altered heart rate, increased blood pressure, nausea, vomiting, agitation, altered gait, dizziness, irritability, sedation, confusion, and hallucinations. Delirium, psychosis, decreased blood pressure, convulsions, decreased respiration, loss of consciousness, coma, and death may occur. A serious complication can be rhabdomyolysis (muscle damage), followed by kidney failure.
There is no specific antidote for antihistamine overdose, so treatment is symptomatic and supportive. Your doctor will assess the need to induce vomiting, perform stomach lavage, or prescribe medications to increase blood pressure if necessary.
In case of overdose or accidental ingestion, consult the Toxicology Information Service, phone: 91 562 04 20, indicating the medication and the amount ingested.
Do not take a double dose to make up for forgotten doses.
Take your dose at the usual time the next day.
If you have any other questions about the use of this medication, ask your doctor or pharmacist.
