A prescription signed and sealed by a doctor usually refers to a formal prescription note issued by a doctor, which requires the doctor to fill in the signature at the designated position and click the drug seal to ensure the authenticity and effectiveness of the prescription.

At the same time, it is also one of the important means to prevent medical accidents.

In addition to the doctor's signature and seal, the prescription also needs to fill in the basic information and condition of the patient. Doctors also need to use drugs reasonably according to the principle of medication, reminding patients to use drugs correctly and avoiding adverse reactions. Pharmacists also need to check the quality of prescription drugs to ensure that patients can get safe and effective drugs.
