In medicine Medicine is the art and science of healing. It encompasses a range of health care practices evolved to maintain and restore health by the prevention and treatment of illness, a contraindication (pronounced as contra-indication) is a condition or factor that increases the risks Risk concerns the expected value of one or more results of one or more future events. Technically, the value of those results may be positive or negative. However, general usage tends focus only on potential harm that may arise from a future event, which may accrue either from incurring a cost or by failing to attain some benefit ("upside involved in using a particular drug A pharmaceutical drug, also referred to as medicine, medication or medicament, can be loosely defined as any chemical substance intended for use in the medical diagnosis, cure, treatment, or prevention of disease, carrying out a medical procedure, or engaging in a particular activity.
Some contraindications are absolute, meaning that there are no reasonable circumstances for undertaking a course of action. For example, a baby with a fever should never be given aspirin Aspirin , also known as acetylsalicylic acid (pronounced /əˌsɛtɪlsælɪˌsɪlɪk ˈæsɪd/, abbreviated ASA), is a salicylate drug, often used as an analgesic to relieve minor aches and pains, as an antipyretic to reduce fever, and as an anti-inflammatory medication because of the risk of Reye's syndrome Reye's syndrome is a potentially fatal disease that causes numerous detrimental effects to many organs, especially the brain and liver, as well as causing hypoglycemia. The exact cause is unknown, and while it has been associated with aspirin consumption by children with viral illness, it also occurs in the absence of aspirin use, and a person with an anaphylactic Anaphylaxis is an acute multi-system severe type I hypersensitivity reaction. The term comes from the Greek words ανα ana and φύλαξις phylaxis (protection) food allergy A food allergy is an adverse immune response to a food protein. Food allergy is distinct from other adverse responses to food, such as food intolerance, pharmacologic reactions, and toxin-mediated reactions. Food allergies can trigger mental dissorders ranging from ADHD to Schizophrenia. Alcoholism may also be an effect of food allergies should never eat the food to which they are allergic. Similarly, a person with Hemochromatosis Historically, the term haemochromatosis was initially used to refer to what is now more specifically called haemochromatosis type 1 . Currently, haemochromatosis (without further specification) is mostly defined as iron overload with a hereditary/primary cause, or originating from a metabolic disorder. However, the term is currently also used more should not be administered iron preparations.
Other contraindications are relative, meaning that the patient is at higher risk of complications, but that these risks may be outweighed by other considerations or mitigated by other measures. For example, a pregnant woman should normally avoid getting X-rays X-radiation is a form of electromagnetic radiation. X-rays have a wavelength in the range of 10 to 0.01 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3 × 1016 Hz to 3 × 1019 Hz) and energies in the range 120 eV to 120 keV. They are shorter in wavelength than UV rays. In many languages, X-radiation is called R, but the risk may be far less than the risk of not diagnosing or being able to treat a serious condition such as tuberculosis or a broken bone. Relative contraindications may also be referred to as cautions, such as in the British National Formulary The British National Formulary contains a wide spectrum of information on prescribing and pharmacology, among others indications, side effects and costs of the prescription of all medications available on the National Health Service. It is used by general practitioners and specialist practitioners, and by other prescribers (such as nurses,.
