Avoid alcohol. Do not drive if it makes you sleepy. Tell the doctor if you have kidney disease, as the dose may need to be lower. Taking it with strong painkillers (opioids) or sleeping pills can cause heavy drowsiness and slow breathing. It is a prescription-only medicine that can be misused, so we sell it only at our counter against the original prescription.
From our clinic: The dose is lowered slowly when stopping.
