heck no!
can a doctor prescribe a different controlled substance in the middle of the month
No, although a precursor to PCP is on the Schedule II DEA list, it will never be prescribed in this USA. PCP is a Schedule I Controlled Substance.
If it was ordered by a doctor and acquired with a legitimate prescription I would.
the crappy kind.
In the U.S., yes, with the exception of controlled substances.
Only a physician licensed to prescibe medications can sign a patient's presciptions. Office staff or a nurse may write out the doctor's order, but each script must be signed by a licensed physician.
A controlled substance is one that is addictive. Either a nurse or a doctor may administer a controlled substance. In a hospital setting, the doctor may write the order for the medication, and a nurse will later administer it.
No, carisoprodol is already in a sense a controlled substance, only available by doctor's administration or prescription.
Per HIPPA, disclosure of medical information must be secure and controlled. In this case, if the Doctor is a resident of the hospital where the patient resides, the Doctor is considered a secure and controlled release. It is under a HIPPA rule, a disclosure, but not a violation. A visiting Doctor is not allowed access to patient records without the patient consent.
No antibiotics are controlled. Controlled substances are those which have a possibility of dependency.
Yes, they can write prescriptions for themselves but ONLY for non-controlled substances. (Controlled substances are those determined to have a significant amount of abuse potential, for instance many pain killers and sleep meds.) However, generally it's recommended that doctors seek an outside opinion instead of self-prescribing.
It's not the patient who decides what the doctor will prescribe. It is however the patient's choice whether he wants to take the medicine or not. And the doctor can not change the content of the pill. The pills comes from the factory, ready made.
