In clinical work, I often encounter this problem: some patients or family members find me the next day after seeing a doctor and say to me: after reading the drug instructions, I feel that the side effects are too serious to take the drug. Here I would like to explain to you: 1. At the present level of technology, it is not possible to manufacture drugs without any side effects, and the relevant national regulations clearly stipulate that you cannot claim that your drugs do not have any toxic side effects in the advertisement. Although humans have been very advanced in some aspects, but the knowledge of their own is still far from. 2, take medicine to obtain therapeutic effect, as long as the benefits outweigh the disadvantages, you should follow the medical advice to take the medicine. This is a dialectical problem, just like not choking on food. 3, read the drug instructions, look at the contraindications and caution, if your situation is consistent with the contraindications, never use, if belong to the list of caution, try not to use. If there is any discomfort after taking the drug, consult your doctor, and then listen to your doctor’s advice on how to deal with it. 4, each person after taking the drug, the actual side effects produced far less than the instructions on the side effects, or mild. If a drug frequently has all the side effects stated in the instructions, then such a drug is certainly not approved for marketing. The key misconception here is a problem of incidence, such as rare side effects, the incidence of 1/10,000, what is this concept? The number of people killed by car accidents in Tianjin in recent years is about 1000 per year, and the total population of Tianjin is 11 million. In other words, the number of people who die in car accidents in Tianjin is about 1/10,000 per year, but who would be afraid to go out on the street because of the fear of car accidents? 5. Then why do drug instructions have to be written in this way? The reason is: on the one hand, the manufacturers are responsible for the patients and will tell everyone what may happen; on the other hand, if the patients have side effects that are not mentioned in the instructions, then the patients have the right to ask the manufacturers to compensate for the loss, so the manufacturers will write all the possible side effects, even the very rare ones, into the instructions. 6.Neither be overly afraid nor take it lightly, because there are also serious side effects after taking drugs, such as malignant syndrome caused by psychotropic drugs, which have a certain danger once they appear and must be seen immediately, but the actual occurrence rate is very low. 7. It is especially recommended that those who are highly suggestive or particularly concerned about their own bodies should read the drug instructions less often, because some people may have reactions that should not have occurred originally under self-referral, and if these people are unsure, they can ask their family members to read the instructions.
