👉 Allergic reactions in the context of Drug tolerance

Drug tolerance or drug insensitivity is a pharmacological concept describing subjects' reduced reaction to a drug following its repeated use. Drug tolerance develops gradually over time. Increasing its dosage may re-amplify the drug's effects; however, this may accelerate tolerance, further reducing the drug's effects. Drug tolerance is indicative of drug use but is not necessarily associated with drug dependence or addiction. The process of tolerance development is reversible (e.g., through a drug holiday) and can involve both physiological factors and psychological factors. Tolerance can occur with drugs taken for pharmaceutical or recreational purposes.

One may also develop drug tolerance to side effects, in which case tolerance is a desirable characteristic. A medical intervention that has an objective to increase tolerance (e.g., allergen immunotherapy, in which one is exposed to larger and larger amounts of allergen to decrease one's allergic reactions) is called drug desensitization.

Allergic reactions in the context of Paclitaxel

Paclitaxel, sold under the brand name Taxol among others, is a chemotherapy medication used to treat ovarian cancer, esophageal cancer, breast cancer, lung cancer, Kaposi's sarcoma, cervical cancer, and pancreatic cancer. It is administered by intravenous injection. There is also an albumin-bound formulation.

Common side effects include hair loss, bone marrow suppression, numbness, allergic reactions, muscle pains, and diarrhea. Other side effects include heart problems, increased risk of infection, and lung inflammation. There are concerns that use during pregnancy may cause birth defects. Paclitaxel is in the taxane family of medications. It works by interference with the normal function of microtubules during cell division.

Allergic reactions in the context of Diphtheria antitoxin

Diphtheria antitoxin (DAT) is a medication made up of antibodies used in the treatment of diphtheria. It is no longer recommended for prevention of diphtheria. It is administered through injection into a vein or muscle.

Side effects are common. They include serum sickness and allergic reactions including anaphylaxis. Diphtheria antitoxin is made from the blood plasma of horses that have been immunized against diphtheria toxin. It works by neutralizing the toxins produced by Corynebacterium diphtheriae.

Allergic reactions in the context of Docetaxel

Docetaxel (DTX or DXL), sold under the brand name Taxotere among others, is a chemotherapy medication used to treat a number of types of cancer. This includes breast cancer, head and neck cancer, stomach cancer, prostate cancer and non-small-cell lung cancer. It may be used by itself or along with other chemotherapy medication. It is given by slow injection into a vein.

Common side effects include hair loss, cytopenia (low blood cell counts), numbness, shortness of breath, nausea, vomiting, and muscle pains. Other severe side effects include allergic reactions and future cancers. Docetaxel induced pneumotoxicity is also a well recognized adverse effect which has to be identified timely and treated after withholding the drug. Side effects are more common in people with liver problems. Use during pregnancy may harm the baby. Docetaxel is in the taxane family of medications. It works by disrupting the normal function of microtubules and thereby stopping cell division.

Allergic reactions in the context of Tuberculin

Tuberculin, also known as purified protein derivative, is a combination of proteins that are used in the diagnosis of tuberculosis. This use is referred to as the tuberculin skin test and is recommended only for those at high risk. Reliable administration of the skin test requires large amounts of training, supervision, and practice. Injection is done into the skin. After 48 to 72 hours, if there is more than a five to ten millimeter area of swelling, the test is considered positive.

Common side effects include redness, itchiness (pruritus), and pain at the site of injection. Allergic reactions may occasionally occur. The test may be falsely positive in those who have been previously vaccinated with BCG or have been infected by other types of mycobacteria. The test may be falsely negative within ten weeks of infection, in those less than six months old, and in those who have been infected for many years. Use is safe in pregnancy.

Allergic reactions in the context of Fresh plasma

Fresh frozen plasma (FFP) is a blood product made from the liquid portion of whole blood. It is used to treat conditions in which there are low blood clotting factors (INR > 1.5) or low levels of other blood proteins. It may also be used as the replacement fluid in plasma exchange. Using ABO compatible plasma, while not required, may be recommended. Use as a volume expander is not recommended. It is administered by slow injection into a vein.

Side effects include nausea and itchiness. Rarely there may be allergic reactions, blood clots, or infections. It is unclear if use during pregnancy or breastfeeding is safe for the baby. Greater care should be taken in people with protein S deficiency, IgA deficiency, or heart failure. Fresh frozen plasma is made up of a complex mixture of water, proteins, carbohydrates, fats, and vitamins. When frozen it lasts about a year.

Allergic reactions in the context of Hyperimmune globulin

Immunoglobulin therapy is the use of a mixture of antibodies (normal human immunoglobulin) to treat several health conditions. These conditions include primary immunodeficiency, immune thrombocytopenic purpura, chronic inflammatory demyelinating polyneuropathy, Kawasaki disease, certain cases of HIV/AIDS and measles, Guillain–Barré syndrome, and certain other infections when a more specific immunoglobulin is not available. Depending on the formulation it can be given by injection into muscle, a vein, or under the skin. The effects last a few weeks.

Common side effects include pain at the site of injection, muscle pain, and allergic reactions. Other severe side effects include kidney problems, anaphylaxis, blood clots, and red blood cell breakdown. Use is not recommended in people with some types of IgA deficiency. Use appears to be relatively safe during pregnancy. Human immunoglobulin is made from human blood plasma. It contains antibodies against many viruses.
