INDIANAPOLIS (AP) — The top Republican in the Indiana House says he believes doctor’s prescriptions should be required for cold medications containing a drug that’s often used in making methamphetamine.

House Speaker Brian Bosma said Tuesday he knows making pseudoephedrine medications by prescription only will be an inconvenience for many people, but says the state is being hurt by the scourge of meth.

Indiana has for several years been among the states with the most meth lab seizures. Indiana law now limits the quantity of pseudoephedrine medications that consumers can buy, but Bosma says he believe the state’s sales tracking system is insufficient.

Bosma hasn’t supported similar prescription requirement proposals that have failed in the Legislature in recent years.

Opponents maintain requiring prescriptions will increase health care costs by driving up doctor visits.
