• In the control of muscle spasm in tetanus.
• In selected cases of cerebral palsy and in the treatment of other
forms of muscle spasm.
• In the treatment of some forms of epilepsy.

• In the control of muscle spasm in tetanus.
• To control tension and irritability in selected cases of cerebral palsy.

Both adults and children can take a small dose of Diazepam before an
operation to help with relaxation and to cause sleepiness.


muscle relaxants (eg baclofen, tizanidine, suxamethonium, tubocurarin),

being when taken with diazepam, which can increase your desire to
continue taking these medicines (dependency) or can make you very
barbiturates such as phenobarbital (to treat epilepsy and mental
medicines to lower high blood pressure e.g. captopril, enalapril or

antacids (reduces stomach acid) may slow down absorption of
diazepam in the body.

disulfiram (to treat alcohol addiction). Taking this medicine with
diazepam could make you very sleepy and can cause diazepam
to be removed from the body more slowly than usual.
medicines for epilepsy e.g. Phenobarbital, phenytoin,
carbamazepine, or sodium valproate, (diazepam can affect the blood
levels of these medicines). Diazepam can furthermore affect how
phenytoin works.
theophylline (to treat asthma and other breathing disorders), as it can
weaken the effect of diazepam. As this can cause diazepam to be
removed from the body more quickly than usual.
Cimetidine, omeprazole or esomeprazole (stomach acid reducing
medicines), as these can cause diazepam to be removed from the
body more slowly than usual.
rifampicin, to treat infections (an antibiotic) as this can cause
diazepam to be removed from the body more quickly than usual. The
effect of diazepam can be weakened.
amprenavir, atazanavir, ritonavir, delavirdine, efavirenz, indinavir,
nelfinavir or saquinavir (antivirals) as these can make you feel sleepy
for longer or cause difficulty breathing.
fluconazole, voriconazole, itraconazole or ketoconazole (antifungal
medicines) as these can cause diazepam to be removed from the body
more slowly than usual and therefore increase the risk of side effects.
isoniazid (used to treat tuberculosis), as it can cause diazepam to be
removed from the body more slowly than usual.
oestrogen-containing contraceptives, as they can slow down the
removal of diazepam from the body and increase its effect.
Breakthrough bleeding can occur when taking diazepam and oral
contraceptives together, but the contraceptive protection is not reduced.
cisapride (used to treat stomach problems), as it can cause
diazepam to be removed from the body more slowly than usual.
corticosteroids (medicines used to treat inflammation in the body) as
they can weaken the effect of diazepam.
Levodopa (to treat Parkinson’s disease) as diazepam may cause
levodopa to not work so well.
valproic acid (used to treat epilepsy and mental disorders) as it can
slow down the removal of diazepam from the body and increase its
ketamine (an anaesthetic) as diazepam increases the effect of
lofexidine (to help relieve symptoms when you stop taking opioids)
nabilone (to treat nausea and vomiting),
alpha blockers or moxonidine (to lower high blood pressure),
neuroleptics (for mental illness) and other medicines for mental
illness such as zotepine, tranquilisers (sleeping tablets).
Beta-blockers (e.g. propanolol or atenolol for heart problems)

If you are going to have an operation involving an anaesthetic, the
hospital will need to know in advance that you are taking Diazepam.

Diazepam with food and drink
Do not drink alcohol while you are taking diazepam. Alcohol may increase
the sedative effects of Diazepam and make you very sleepy. If you
regularly drink alcohol please tell your doctor before using this medicine.

Other considerations
• Mental side effects – contact your doctor if you experience side
effects such as agitation, hyperactivity, restlessness, aggressiveness,
nightmares or hallucinations. These side effects are more likely to
occur in children or the elderly.
• Amnesia (total or partial memory loss) – you could experience
amnesia when taking this medicine. Amnesia is more likely to occur
when taking high doses of diazepam.
• Dependence – there is a risk of dependence, which increases with
the dose and duration of treatment and if you have a history of
alcoholism and drug abuse. Therefore, you should take Diazepam
tablet for as short period of time as possible.
• Tolerance – if after a few weeks you notice that the tablets are not
working as well as they did when first starting treatment, you should
go and see your doctor.
• Withdrawal – treatment should be gradually withdrawn. Withdrawal
symptoms occur with Diazepam tablets even when normal doses are
given for short periods of time. See Section 3, ‘If you stop taking

Grapefruit juice may increase the amount of diazepam in your blood. If
you are elderly, suffer from cirrhosis or any of the conditions listed in
section 2, this could possibly increase the sedative effects of Diazepam
and you should speak to your doctor or pharmacist.

Drinks containing caffeine may reduce the effects of diazepam.

Pregnancy and breast-feeding
You should not take Diazepam if you are pregnant, planning to become
pregnant or if you are breast-feeding. If you take Diazepam late in your
pregnancy or during labour your baby might have a low body
temperature, floppiness, breathing and feeding difficulties. If you take
this medicine regularly during late pregnancy, your baby may develop
withdrawal symptoms.
Ask your doctor or pharmacist for advice before taking this medicine.

Driving and Using machines:
Diazepam may make you feel sleepy, affect your concentration or you
may have problems with the way your muscles work.

Do not:
• drive or use any tools or machines if you are affected in this way
• take part in other activities where this would put you or others at risk
• drink alcohol, as this will make these effects worse.

You should take the lowest dose possible and you should not
continue the treatment beyond 4 weeks

If any of the above apply to you or you are unsure, please talk to your
doctor before taking the medicine.

You should make sure that you get enough sleep, otherwise you may
experience difficulty staying alert. If this happens do not drive, use tools
or operate machines.
