I'm not sure exactly what you mean by control, and if you mean print ads, tv ads etc. If by control, you mean that prescription drug ads should be true, I agree. Ads should be straightforward and clear about the side effects of prescription drugs. They shouldn't be delivered a misleading or dishonest manner.
Prescription drug ads should not even be allowed to advertise. Doctors should be prescribing medicines based on the needs of their patients. Patients should not be able to watch a commercial and then come in and ask for some medication based on a commercial. It is unethical for these companies to advertise.
There should be more control over prescription drug ads. This is because these ads have caused so many people to request these drugs from their doctors, and have created a nation of people that are treated with chemicals that produce harmful side effects. Prescription drug ads need to have a restrictive air time, such as after 10 p.m. or before 6 a.m. -- times when few people are awake.
I do not believe there should be more control over prescription drug ads. Truth be told, there is already a great deal of control over these ads. Personally, I do not believe the American public needs these ads. I think medication decisions should be left up to physicians, not the patients.
There is an absurd amount of control over even the simplest types of medication - ever since the meth epidemic began, even cough medicine as well - while, at the same time, supplements are not governed by the same rules. Only very dangerous drugs should be controlled so tigtly by the government.
