n correctly. Careful counseling about noncontraceptive benefits and common
side effects is essential to prevent discontinuation and inadvertent pregna
ncy. Successful management of common complaints fan be accomplished by iden
tifying and modifying estrogen and progestin-related side effects. Emergenc
y contraceptive pills can be taken within 72 hours of unprotected intercour

phone.
