Warnings and precautions
Talk to your doctor or pharmacist before taking Benadon.
Do not take Benadon at doses higher than recommended, or for longer periods. At daily doses of 300 mg (1 tablet) or higher, vitamin B6 should not be taken for more than 5 months. After 5 months of treatment, a suspension of at least 25 days is necessary.
If these recommendations are not followed, severe neurotoxicity may occur (risk of overdose, see “If you take more Benadon than you should”).
