Always take FIRDAPSE exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
The dose you should take is established by your doctor based on the intensity of your symptoms. This dose suits you only.
The starting dose is 5 mg (half a tablet) three times daily (i.e. 15 mg per day). Your doctor may increase this dose slowly first to 5 mg (half a tablet) four times daily (i.e. 20 mg per day). Then your doctor may continue to increase your total daily dose adding 5 mg (half a tablet) per day, every 4 or 5 days.
The maximum recommended dose is 60 mg per day (i.e. a total of six tablets to be taken at intervals during the day). Total daily doses above 20 mg should be divided into two to four separate doses. No single dose should exceed 20 mg (two tablets).
The tablets have a score-line to allow them to be broken in half. The tablets should be swallowed with some water and are to be taken with food.
Patients with liver/kidney problems:
FIRDAPSE should be used with caution in patients with liver or kidney problems. A starting dose of 5 mg FIRDAPSE is recommended in patients with moderate or severe impairment of liver or kidney function. For patients with mild impairment of liver or kidney function a starting dose of 10 mg FIRDAPSE is recommended. For these patients the dose of FIRDAPSE should be increased more slowly than in those without liver or kidney problems with doses increased in 5 mg increments every 7 days. If any adverse events occur, please consult your doctor as you may need to stop increasing the dose.
If you take more FIRDAPSE than you should
If you take more FIRDAPSE than you should have, you may feel weak, nauseous, and experience mild tingling or numbness in part of your body. Depending on how much FIRDAPSE you have taken, you may also suffer from convulsions, vomiting or problems with your heart (cardiac rhythm disorders). If you experience any of these symptoms, you should contact your doctor or pharmacist immediately.
If you forget to take FIRDAPSE
If you forget to take FIRDAPSE, do not take a double dose to make up for the dose you have forgotten but continue to take your treatment as prescribed by your doctor.
If you stop taking FIRDAPSE
If the treatment is stopped, you may experience symptoms such as tiredness, slow reflexes and constipation. Do not stop treatment without consulting your doctor.
