What Antenex is used for
Antenex is used to:

Antenex contains the active ingredient diazepam, which belongs to a group of medicines called benzodiazepines. These medicines are thought to work by their action on brain chemicals.
Benzodiazepines are not recommended as the only treatment of severe mental illnesses and should not be used alone to treat depression.
Ask your doctor if you have any questions about why Antenex has been prescribed for you.
Your doctor may have prescribed Antenex for another reason.
In general, benzodiazepines such as Antenex should be taken for short periods only (for example 2 to 4 weeks). Continuous long-term use is not recommended unless advised by your doctor. The use of benzodiazepines may lead to dependence on the medicine.
Anxiety and tension associated with the normal stress of everyday life usually does not require treatment with medicines.
Antenex is not recommended for use in children under 6 months of age.
Antenex is available only with a doctor’s prescription.
