Other medicines and Clonazepam

Tell your doctor of pharmacist if you are taking, have recently taken or might take any other medicines.

In particular tell your doctor of pharmacist if you are taking any of the following medicines:

other medicines to treat epilepsy, such as carbamazepine, hydantoins, phenobarbital, phenytoin, primidone or sodium valproate
cimetidine (medicine used to treat stomach problems)
rifampicin (an antibiotic)
anaesthetics
medicines to make you sleep (hypnotics)
medicines that help with anxiety (tranquillisers)
pain killers (analgesics) or medicines to relax your muscles (muscle relaxants)
If you any of the above applies to you (or you are not sure), talk to your doctor or pharmacist before taking Clonazepam.
Concomitant use of Clonazepam and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.
However if your doctor does prescribe Clonazepam together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor.
Please tell your doctor about all sedative medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.
Clonazepam with alcohol
Do not drink alcohol whilst taking Clonazepam as it may cause fits (epileptic seizures) and increase the risk of having side effects.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
Clonazepam may affect your ability to drive, operate machinery and other hazardous activities, particularly in the first few days of treatment. This may be made worse if you drink alcohol. Increasing the dose of clonazepam or changing the time that you take it may also slow your reactions. You should not drive unless your doctor says you can.
The medicine can affect your ability to drive as it may make you sleepy or dizzy.
- Do not drive while taking this medicine until you know how it affects you.
- It is an offence to drive if this medicine affects your ability to drive.
- However, you would not be committing an offence if:
  - The medicine has been prescribed to treat a medical or dental problem and
  - You have taken it according to the instructions given by the prescriber or in the information provided with the medicine and
  - It was not affecting your ability to drive safely.

If you think the effect of Clonazepam is too strong or too weak, talk to your doctor. Do NOT change the dose yourself.

Increase in number of fits (epileptic seizures) may occur during long-term treatment or in patients with a rare condition called porphyria.
