Use and acceptance of the "Paper Pill" among an urban clinic population.

A randomized, crossover study comparing the acceptability of two presentations of the same oral contraceptive, a paper formulation and the conventional tablet, was carried out among two-hundred-and-seventy women attending two urban family planning clinics in Mexico City. During the first three cycles of use, the percentage of women discontinuing the medication for side effects was almost identical in the two groups. Although the paper formulation failed to demonstrate any major advantage in terms of continuation or acceptability, it was preferred by a majority of the women who began oral contraception with its use.
