More than 1,100 women each month in the Inland Northwest take the morning-after pill to avoid pregnancy, a number that could rise after the federal Food and Drug Administration agreed Thursday that adults can buy the drug without a prescription. The move is expected to provide easier access to emergency contraception in Idaho and to broaden it in Washington, where select pharmacists already are able to provide the pills, known as Plan B, without a doctor's visit. Girls 17 and younger in Washington will still need a pharmacist's approval to buy the pills, which are expected to be available by the end of the year. In Idaho, girls will need a prescription. Those seeking the drugs will have to prove they're at least 18 to a pharmacist, who will keep the drug behind a counter.
