epilepsy and mental disorders)
• medicines to lower high blood pressure,
diuretics (water tablets), nitrates (for heart

sleepy and suppress your breathing and blood

phenytoin and carbamazepine, sodium
valproate, (diazepam can affect the blood
levels of these medicines). Diazepam can

• isoniazid (used to treat tuberculosis), as it
can cause diazepam to be removed from the
body more slowly than usual.

the sedative effects of Diazepam oral solution

suffer from cirrhosis or any of the conditions
listed in section 2, this could possibly increase
the sedative effects of Diazepam oral solution
and you should speak to your doctor or
Drinks containing caffeine may reduce the
effects of diazepam.

if you are pregnant, planning to become
pregnant or are breast feeding. If you take
