1. What Diazepam oral solution is and what it is used for
Diazepam belongs to a group of medicines called benzodiazepines. Diazepam helps in the treatment of anxiety, muscle spasms and convulsions (fits). It is used to treat:
- short term relief (14 days) of severe anxiety and may occur alone or with insomnia (trouble sleeping) or mental health problems
- cerebral palsy
- muscle spasm caused by tetanus (when taken with other medicines)
- epilepsy (when taken with other medicines)
- patients with the symptoms of alcohol withdrawal
- helping to relax nervous dental patients.
- tension and irritability caused by cerebral spasticity
- helping to relax and cause sleepiness before an operation.

- 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 – when taking this medicine there is a risk of dependence, which increases with the dose and duration of treatment and also in patients with a history of alcoholism and drug abuse. Therefore, you should take Diazepam oral solution for as short period of time as possible.
- Tolerance – if after a few weeks you notice that the oral solution is not working as well as it did when first starting treatment, you should go and see your doctor.
- Withdrawal – treatment should be gradually withdrawn. Withdrawal symptoms occur with Diazepam oral solution even when normal doses are given for short periods of time.
See Section 3, ‘If you stop taking Diazepam’.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. Especially:
- antidepressants (e.g. fluvoxamine, fluoxetine)
- antipsychotics such as clozapine (to treat mental problems)
- antihistamines (to treat allergies)
- general anaesthetics
- sedatives (used to give calming effects)
- hypnotics (to help you sleep)
- erythromycin (an antibiotic)
- muscle relaxants (e.g. suxamethonium, tubocurarin)
- some strong pain killers such as morphine (opioids) may give you a heightened sense of well being when taken with diazepam, which can increase your desire to continue taking these medicines (dependency) or can make you very sleepy.
- barbiturates such as phenobarbital (to treat epilepsy and mental disorders)
- medicines to lower high blood pressure, diuretics (water tablets), nitrates (for heart conditions) as these could lower your blood pressure too much.
- antacids (reduces stomach acid) may slow down absorption of diazepam in the body.
Taking these medicines with diazepam could affect your mental status, make you very sleepy and suppress your breathing and blood pressure.
- 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 and carbamazepine, 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.
- amrenavir, atazanavir, ritonavir, delavirdine, efavirenz, indinavir, nelfinavir or saquinavir (antivirals), fluconazole, itraconazole, ketoconazole or voriconazole (anti-fungal medicines) as these can cause diazepam to be removed from the body more slowly than usual and therefore increase the risk of side effects. As these can make you feel sleepy for longer or cause difficulty breathing.
- isoniazid (used to treat tuberculosis), as it can cause diazepam to be removed from the body more slowly than usual.
- oral 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 (used to treat Parkinson’s disease). Diazepam can reduce the effect of levodopa.
- valproic acid (used to treat epilepsy and mental disorders) as it can slow down the removal of diazepam from the body and increase its effect.
- ketamine (an anaesthetic) as diazepam increases the effect of ketamine.
- 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)
- sodium oxybate, used to prevent episodes of sudden onset of sleep (narcolepsy) with muscle weakness. Enhanced effect of the sodium oxybate when used in combination with Diazepam.
