Diazepam: use during pregnancy and lactation
It contraindicated in I trimester of pregnancy (It increases the risk of congenital malformations). In II and III trimester of pregnancy is possible, if the effect of therapy outweighs the potential risk to the fetus. At the time of treatment should stop breastfeeding.
Diazepam: side effects
From the nervous system and sensory organs: slackness, drowsiness, fatigue; ataxia, blunting of emotions, blurred vision, diplopia, nistagmo, tremor, reaction speed and concentration, deterioration in short-term memory, dysarthria, slurred speech; confusion, depression, fainting, headache, dizziness; paradoxical reactions (severe agitation, alarm, hallucinations, nightmares, fits of rage, misbehavior); anterogradnaya amnesia.
Cardio-vascular system and blood (hematopoiesis, hemostasis): bradycardia, neutropenia.
From the digestive tract: violation of salivation (dry mouth or hypersalivation), nausea, constipation.
Other: allergic reactions (hives, rash), urinary incontinence, urinary retention, changes in libido, increase in liver transaminases and alkaline phosphatase, jaundice.
For parenteral administration: injection site reactions (thrombosis, phlebitis, the formation of infiltrates); with the rapid on/in the introduction-gipotenzia, cardiovascular collapse, violation of the respiratory function, Ikotech.
Perhaps the development of addiction, Drug Dependence, withdrawal, aftereffect syndrome (muscular weakness, decreased performance), rebound syndrome (cm. Precautions).
Diazepam: interaction
Potentiates the effects of alcohol, anticonvulsants and antihypertensives, neuroleptics, tricyclic antidepressants, analgesics (incl. narcotic analgesics), hypnotic drugs, general anesthetics, muscle relaxants, antihistamine drugs with sedative effect. Analeptiki, psychostimulants-reduce activity. Antacids may decrease the speed, but not the extent of absorption of diazepam.
Isoniazid slows excretion of diazepam (and increases its concentration in blood). Inhibitors of microsomal oxidation (incl. cimetidine, ketoconazole, fluvoxamine, fluoxetine, omeprazole) alter the pharmacokinetics and increase the duration of the effect of diazepam. Rifampicin reduces the concentration of diazepam in the blood. Erythromycin slows the metabolism of diazepam in the liver. Diazepam may alter plasma concentrations of phenytoin.
Diazepam: overdose
Symptoms: CNS depression of varying severity (from drowsiness to coma): severe drowsiness, slackness, weakness, decreased muscle tone, ataxia, prolonged confusion, oppression reflexes, coma; also possible hypotension, respiratory depression.
Treatment: induction of vomiting and the appointment of activated carbon (If the patient is conscious), Gastric lavage through a tube (If the patient is unconscious), simptomaticheskaya therapy, monitoring vital functions, in / in a liquid (to enhance diuresis), if necessary, ventilation. In the development field should not be used barbiturates. As a specific antidote used benzodiazepine receptor antagonist flumazenil (in hospital). Hemodialysis maloeffyektivyen.
Diazepam: Dosing and Administration
Inside, I /, / m, rectally. The mode set is strictly individual, depending on the evidence, the disease, portability, etc.. Treatment should start with the lowest effective dose, corresponding specific form of pathology.
Usual adult dosage when administered: Elementary-5-10 mg, daily — 5-20 mg, the maximum single- 20 mg, the maximum daily 60 mg.
The on/in and/m introduction the average single dose for adults is 10 mg, average daily — 30 mg, the maximum single- 30 mg, the maximum daily 70 mg. The duration of treatment with parenteral administration should not exceed 3-5 days (then, if necessary, moving to a reception inside), the total duration of treatment should be as short as possible and should not exceed 2-3 months (including the period of gradual reduction of the dose). Increasing the duration of treatment in excess of 2-3 months is possible only after repeated careful assessment of the patient. Before re-rate the break must be at least 3 Sun.
The dose and duration of treatment for children picked individually, depending on the nature of the disease, age, body weight of the child.
Patients in elderly, as well as in patients with impaired liver function should begin treatment with lower doses.
Diazepam: precautions
Not recommended for monotherapy of benzodiazepines in combination with depression anxiety (possible suicide attempts). Due to the possibility of paradoxical reactions, incl. aggressive behavior, used with caution in patients with personality and behavioral disorders. Paradoxical reactions occur more often in children and elderly patients. In the event of paradoxical reactions diazepam should be discontinued.
During treatment with diazepam is unacceptable consumption of alcoholic beverages.
Should not be used during the drivers of vehicles and people, whose work requires quick mental and physical reactions, and is associated with high concentration of attention.
Diazepam in children under 14 years is allowed only in well justified cases, the duration of treatment should be minimal.
When receiving diazepam (Even at therapeutic doses) may develop addiction, formation of physical and psychological dependence. The risk of dependence increases when using large doses and with increasing duration of administration, as well as in patients with drug and alcohol addiction in history. Abolition of diazepam should be gradual, by reducing the dose, to reduce the risk of withdrawal and rebound-syndrome. When abrupt cancellation after long-term use or high doses occurs withdrawal (headache and muscle pain, anxiety, alarm, confusion, tremor, convulsions), in severe cases, depersonalization, hallucinations, seizures (abrupt withdrawal of epilepsy). Transient syndrome, whereby symptoms, served as the reason for the appointment of diazepam, resumed in a more pronounced form (rebound syndrome), It may also be accompanied by changes in mood, anxiety, etc..
Prolonged use should be periodically monitored picture peripheral blood and liver function.
Use at doses above 30 mg (especially the / m or /) during 15 hours before giving birth can cause neonatal apnea, gipotenziю, gipotermiю, rejection of the breast, etc..
There are cases of benzodiazepine addiction.
Diazepam: Special instructions
It should be taken into account, that anxiety or stress, associated with daily stress, usually does not require treatment with anxiolytics.
Not be mixed in the same syringe with other drugs diazepam (possible deposition of the drug on the walls). The on / in the introduction should be administered in a large vein and slowly, Monitoring respiratory function. Avoid getting the solution in the artery and extravasal space.
