Drugs are a double-edged sword, reasonable use of drugs can cure the disease, misuse will hurt the body. Common misconceptions about medication: one avoid arbitrary abuse, many patients with chronic diseases think they have been sick for a long time into the doctor, the situation with the feeling of random medication, easy to cause adverse consequences; two avoid the use of secret recipes, prescriptions, test prescriptions, some patients who have been ill for many years, long treatment, easy to hold the idea of trying, gullible to those who have not been scientifically verified secret prescriptions; three avoid the use of tonic drugs, the elderly tend to care about their health, like to use tonic drugs, in fact, a normal diet of healthy elderly people do not need to take tonic drugs, frail elderly should also be in the doctor’s office. In fact, healthy elderly people with normal diet do not need to take tonic drugs, frail elderly people, should also be used under the guidance of a doctor; fourth avoid the abuse of antibiotics, vitamins or hormones, these drugs can not be abused as a “panacea”, if necessary, under the guidance of a doctor to use. “The rational use of drugs to do ‘can not be used, can be used less not more, can be taken orally not injected, can be injected not infusion’. Oral administration is the most commonly used, safest, most convenient and most economical method of drug delivery.” Experts remind, despite the endless new drugs, but diet, exercise and other non-drug treatment means, is still the basic treatment of some diseases. In addition, the people should follow the hierarchy of treatment, “small diseases in the community, major diseases go to the hospital, recovery back to the community”, to avoid blindly go to the big hospital consultation. Experts reminded that patients can use “smart medical” services. You can register in advance through the Internet, telephone or the self-service registration machine in the hospital, and the registration form states the time of consultation, so you can step on the point to see the doctor. The citizen card can also be used for inter-visit settlement, reducing waiting time and queuing. “Remember to bring your valid ID (ID card, family register, social security card, etc.), as well as your past medical records and tests to help the doctor make a quicker and more accurate judgment. It is important to be truthful, accurate and comprehensive when describing your condition to the doctor, and not to exaggerate or conceal it at will.” In addition, when symptoms of fever or diarrhea occur, go to a nearby general hospital with a fever or intestinal (diarrhea) clinic above the second level. It is best to have an annual health checkup to achieve early detection and treatment.
