How to take TEVA-CLOBAZAM:
TEVA-CLOBAZAM is a tablet to be taken by mouth. The tablets can be taken whole, or broken in half along the score line.
Always follow your healthcare professional’s instructions. Do not change the prescribed dose yourself. If you think the effect of your medicine is too weak or too strong, talk to your healthcare professional.
Do not stop taking TEVA-CLOBAZAM without talking to your healthcare professional. Stopping a seizure medicine suddenly can cause serious problems, including seizures that will not stop. Your healthcare professional will tell you if and when you or your child can stop taking this medicine.
If the daily dose of TEVA-CLOBAZAM is to be divided, the higher portion should be taken at night (up to 30 mg may be taken as a single dose at night).
If you or your child are taking TEVA-CLOBAZAM for an extended period of time, your healthcare professional will perform regular blood tests for liver, kidney and thyroid function.
Usual dose:
Adults: The starting dose is 5-15 mg/day increasing gradually to a maximum daily dose of 80 mg if needed.
Children from 2 to 16 years: The starting dose is 5 mg/day, which can be increased at 5 day intervals to a maximum daily dose of 40 mg/day if needed.
Infants <2 years: The dose is based on body weight and will be determined by your healthcare professional.
Elderly patients (>65 years), patients with kidney, liver or breathing problems, muscle weakness or dizziness and unsteadiness when walking (spinal or cerebellar ataxia) and patients who are poor metabolizers of antiepileptic drugs (CYP2C19 poor metabolizers) may require lower doses.
Your doctor will slowly decrease your dose and will tell you when to stop taking the medicine. Always follow your doctor’s instructions on how to lower your dose carefully and safely to avoid experiencing withdrawal symptoms.
Overdose:
| If you think you, or a person you are caring for, have taken too much TEVA-CLOBAZAM, contact a healthcare professional, hospital emergency department or regional poison control centre immediately, even if there are no symptoms. |

You may have trouble walking, reacting, breathing, staying awake, or have low blood pressure. A coma or death is possible. Taking alcohol or other drugs that affect your nervous system at the same time as TEVA-CLOBAZAM increases the risk of death. When too much TEVA-CLOBAZAM wears off, you could be excited and jittery.
Missed Dose:
If you or your child misses a dose of TEVA-CLOBAZAM, take it as soon as you remember. If you are close to your next dose, just take your next dose, without making up for the missed dose. Do not take 2 doses at the same time.
