There is also a 12-hour extended-release form of pseudoephedrine; it should also start working within half an hour of taking your first dose, but will last much longer. Because it can last up to 12 hours, remember that you should not take more than two tablets in a 24-hour period.
(d) A person may not purchase drugs containing more than three and six-tenths (3.6) grams of ephedrine or. pseudoephedrine, or both, on one (1) day, or more than seven and two-tenths (7.2) grams of ephedrine or. pseudoephedrine, or both, in a thirty (30) day period. These limits apply to the total amount of base ephedrine and. pseudoephedrine contained in the products and not to the overall weight of the products.
