Antenex 5 is a drug that contains an active substance called diazepam. It belongs to a group of tranquilizers. It is used to treat insomnia, anxiety, muscle spasms and epilepsy.


It should not be administered to patients who are allergic to diazepam or any other benzodiazepines (e.g. clonazepam, lorazapem, bromazepam and flurazepam).

Antenex 5 must not be used in patients who have respiratory depression (difficulty breathing).

Patients with sleep apnea syndrome should not use this medicine.

It relaxes the muscles and it can not be administered to patients who have an abnormal muscle weakness (e.g. myasthenia gravis).

This drug is excreted via the liver, and if you have a severe liver damage, then you should not apply this medicine.

Caution is required in patients who have kidney problems, depressive disorders and alcoholics.

It is advised that you have eight hours of uninterrupted sleep after taking the drug, because in that way you avoid the occurrence of anterograde amnesia (the phenomenon that you can not remember the events that occurred while you were under the influence of this drug).

This drug can cause psychological and physical dependence, so the treatment should last as short as possible (not more than 4 weeks). Using higher doses over a long periods of time, increases the risk of both, physical and psychological dependence. Patients who become addicted to this drug will develop withdrawal symptoms after discontinuation of therapy.

Alcoholic beverages significantly increase the effects of this drug, so the concomitant use must be avoided.

Antenex 5, pregnancy and lactation

Use of this drug during pregnancy, especially during the last trimester of pregnancy, should be avoided due to the possible withdrawal syndrome and the possible occurrence of respiratory depression in infants.

Do not breastfeed your baby while using this medication.


The usual dose for the treatment of insomnia is 5 mg half an hour before bedtime.

The usual dose for the treatment of anxiety is 10 mg every eight hours.
