you should only take six a day for a maximum of one month.
I would like to add that you should read the label on the bottle and if in doubt phone your pharmacist.
In general, 2400 mg per day is considered a maximum dose. Aspirin and ibuprofen are et the top of the list for being able to cause gastric erosion and bleeding if used at high doses for weeks to months. If you need a product like this,Celebrex from your physician may be a better choice.
