Federal law divides medicines into two main classes: prescription medicines and over-the-counter medicines. Dangerous, powerful, or habit-forming medicines to be used under a health care provider's supervision can be sold only by prescription. The prescription must be written by a physician, dentist, or advanced practice nurse; otherwise the pharmacist is forbidden to prepare and fill it.
There are four parts to a drug prescription. The first is the superscription, the symbol ℞ from the Latin recipe, meaning “take.” The second part is the inscription, specifying the ingredients and their quantities. The third part is the subscription, which tells the pharmacist how to compound the medicine. The fourth and last part is the signature; it is usually preceded by an S to represent the Latin signa, meaning “mark.” The signature is where the health care provider indicates what instructions are to be put on the outside of the package to tell the patient when and how to take the medicine and in what quantities. The pharmacist keeps a file of all the prescriptions filled.
prescriptionPharmacology An order for drugs or medical supplies, written, signed or transmitted by word of mouth, telephone, or other means of communication to a pharmacist by a duly licensed physician, dentist, veterinarian or other practitioner, authorized by law to prescribe and administer such drugs or medical supplies. See Frontier prescription, Prescription.
prescriptionAn instruction to a pharmacist, written by a doctor, to dispense a stated quantity of a particular drug in a specified dose.

Patient discussion about prescription
Q. What are some good non-prescription lotions for psoriasis
Q. Can you provide information about how depression can be cured without prescription medications? I was working at a MNC with a high designation. Because of the internal politics I was sent out with a label ‘irresponsible.’ Each and everyone on the chairman’s committee knows very well about my hard work and the benefits they had gotten because of me. This wrong news has gone down the corporate grapevine to other companies and they are not accepting my application. I went into depression and was sick. I have spent all my hard-earned money on medications. Now my pocket is empty. No-one is there to help. I don’t need money from you now but can you provide information about how depression can be cured without prescription medications?
