A prescription is a written order from a healthcare practitioner for a patient's medication. It typically consists of several parts:
\begin{itemize}
\item Superscription: This usually includes the symbol \( \text{R}_x \) (an abbreviation for "recipe," Latin for "take thou"). It sometimes also includes the patient's name, age, sex, and address, as well as the date.
\item Inscription: This is the main part of the prescription and contains the names and strengths of the medication(s) prescribed.
\item Subscription: This section contains the dispensing directions to the pharmacist, such as the form of the medication (e.g., tablets, capsules, solution) and the quantity to be dispensed.
\item Signature (Signa or Sig.): This provides the directions to the patient on how to take the medication, including the dose, frequency, route of administration, and any other relevant instructions (e.g., "take one tablet three times a day after meals").
\end{itemize}
Therefore, the directions to the patient are given under the Signature section of the prescription.
