Today, pharmaceutical companies offer for the needs of medicine, hundreds of thousands of medicines. Decompose in this abundance is difficult even to the specialist (pharmacist, pharmacology, doctor), what to talk about people without medical education. The wealth of information about medicines are delivered through the media (often advertisement) on the one hand, as well as the side effect of a drug (often at the level of rumours) on the other created a lot of a number of "myths" about drugs. This article contains only the most popular.

First myth: There are safer drugs.
Any thing used for other purposes, can bring harm - it is also true for medicines. The medicine is a chemical substance, which in one way or another affects the body. Some drugs are more active, others less. And here there is a certain pattern: the more effective drugs, the more it is dangerous. For example, insulin-for drug substitution therapy in diabetes mellitus-non-compliance with the dosage can cause life-dangerous condition. At the same time, there are drugs with medium and low therapeutic efficacy. But these drugs may be unsafe with incorrect application. For example, aspirin-habitual all means to reduce the temperature-can contribute to exacerbate ulcer disease with all its consequences.

Second myth: The quality of medicine is directly linked to its price: the more expensive the better and vice versa.
Price depends on the volume of drug production, the country of manufacture, delivery costs, brand popularity and other factors not related to its effectiveness. There are as expensive medicines whose effectiveness is low, as well as relatively inexpensive, but effective and safe. For example, domestic products and bifidumbacterin laktobakterin no less efficient than American counterparts primadofilyus and floradofilyus.

Myth Three: If the annotations to the drug described side effects, they are sure to occur if his admission.
Abstract attached to the drug, is designed for the average person. In a special medical literature provides a more detailed, information on drug side effect, calculated on the availability of medical knowledge. The doctor, appointing a medicine, assesses the degree of risk of side effects. If the risk is high, the doctor should warn patients about the possible undesirable effects and how to cope with them. Side effects often arise when excessive doses or prolonged use of uncontrolled drugs. For example analgin all known causes blood oppression in the long handle, but it does not possess such action when off admission. In the development of side effects is important to individual portability and related diseases. Therefore, you need to tell the doctor about the reactions to any drugs that have been before, and the existence of chronic diseases (especially the liver and kidneys). In some cases, you can avoid the undesirable effect of medication, taking it in combination with another drug, levels side-effects first.

Fourth myth: If a doctor appointed medication differently than does the annotations, he made a mistake.
Dosing regime, the multiplicity of reception and duration of admission drug specified in the annotations are recommendatory nature of the average per patient. The doctor also based on the individual characteristics of the patient and his experience, may appoint another medication. Of course, and errors may be related to fatigue, illness (doctors - people, too). So if you see a discrepancy in the appointments recommended by annotations, a doctor said this would not superfluous to clarify contentious points. If a doctor confirmed his appointment, perform them.

Myth Five: Propisannoe medicine can always be replaced by analogue.
There are drugs with different trade names, but equally valid substance: for example, nitroglycerine, which is also sold under trade names: nitrokor, sustak, minitran etc. Such drugs interchangeably, but you need to bear in mind that other drugs may vary in dosage and a filler material dosage forms: pill, capsule, syrup. In another case, similar drugs differ not only in name but also acting substance: enalapril, kaptoprpil, perindopril - APF inhibitors (drugs to treat high blood pressure), but with the existing substances in them - different, so - different effectiveness, side effects, individual portability . Usually, a doctor, appointing medicine, calls and analogues that can replace him. But there are groups of drugs acting in one direction, but on quite different mechanisms. For instance antigipertenzivnye drugs or enalapril kaptopril operate entirely on other mechanisms than nifedipine, verapamil. In this case, replacement medication prescribed (instead enalaprila - nifidipin) will be inadequate, and the expected effect does not occur. If you can not use the designated medication (because of the high cost, deficits or the emergence of side effects), consult with a doctor to replace, but not to make decisions.

Myth sixth: There are drugs that are the panacea for all illnesses.
There are drugs, highly effective for treating some disorders, but even these drugs have no guarantee stoprotsentnoy efficiency. Regarding the widely advertised drugs in recent times from all diseases, it is usually - obschestimuliruyuschie adsorbiruyuschey activity or possessing drugs, which may have a positive effect on the body, but more or less serious pathology, did require a specific and targeted therapy .

Myth seventh: Well-known drugs can be taken without the consent of the doctor.
There are drugs that are familiar to everyone (analgin, but-shpa, paracetamol, etc.). Such drugs are sold without a prescription and do not always require a doctor's appointment. But security receiving such drugs available only when nedlitelnom application in therapeutic dosages, if unchecked begins receiving these drugs, this development is fraught with serious complications. If some medicine is appointed doctor once helped, it does not mean that in future it can be used without consulting the doctor.
