DBL Diazepam Injection contains the active ingredient diazepam. DBL Diazepam Injection belongs to a group of medicines known as benzodiazepines (ben-zo-dye-AZ-eh-peens).

Diazepam has sedative and muscle relaxant effects.
DBL Diazepam Injection is used for a number of conditions, including:
tension and anxiety
repeated or prolonged epileptic seizures (convulsions/fits)
to help relax you before an operation (preoperative medication)
muscle spasm
for the relief of symptoms of alcohol withdrawal
muscle stiffness due to cerebral palsy or paraplegia.
Your doctor may have prescribed diazepam for another reason. Ask your doctor if you
have any questions about why DBL Diazepam Injection has been prescribed for you.
In general, medicines such as DBL Diazepam Injection should be used for short periods

only be given by a doctor, nurse or other trained person.
How long it is given for

Things you should do
Remind any doctor, nurse, dentist or pharmacist who is treating you that you are using
DBL Diazepam Injection.
Things you should not do
Do not stop treatment with this medicine suddenly without speaking to your doctor.
Following long-term use of diazepam, the medicine may not be as effective as it used
to be.
Your doctor may want to gradually reduce the amount of diazepam you have been receiving,

or high doses, may cause unwanted side effects.

Be careful before you drive or use any machines or tools until you know how DBL Diazepam
Injection affects you.
Diazepam may cause dizziness, lightheadedness, drowsiness and disorientation in some
people. It can also affect memory.
If you feel light-headed, dizzy or weak when getting out of bed or standing up, get
up slowly.
Standing up slowly will help your body get used to the change in position and blood
pressure. If this problem continues or gets worse, talk to your doctor.
Additional precaution should be taken by elderly or unwell patients to reduce the
risk of a fall.
DBL Diazepam has the potential to affect driving and has an associated risk with road
safety.

Tell your doctor if you drink alcohol regularly.
Do not drink alcohol while you are given diazepam.
Alcohol may increase the effects of diazepam.
