Hydrocodone, marketed as Vicodin™, is an analgesic formulation including acetaminophen, a medication taken to reduce fever and alleviate pain, and codeine. Usually taken as a tablet, hydrocodone is indicated for pain that is considered to be severe, as well as for persistent diarrhea and coughs. A sometimes rare, allergic reaction to vicodin™ can occur, producing a swollen face, lips, and throat, causing breathing difficulty. Other manifestations include a rash that itches, drowsiness, and chest tightness. An allergic reaction to Vicodin™ is serious and medical attention should be obtained immediately.
Derived from opiates, hydrocodone is classified as a narcotic analgesic, which are drugs especially known for pain-killing and sedating properties. Narcotics are particularly addictive, causing physical symptoms of withdrawal and dependence. Opiates act on the the brain's receptor sites to induce a euphoric relief from pain, though the exact mechanism of action is not completely understood.
Drug allergies come about as a result of an immune system response after taking medication which the body identifies as harmful, producing troublesome effects namely hives and breathing problems. Anaphylaxis is an extremely life-threatening allergic event which comes on rapidly and affects several body systems at once. Having a history of being allergic to a derivative of a medication that caused a reaction previously or a condition that weakens immunity, such as human immunodeficiency virus (HIV), does increase the risk of experiencing an allergic reaction to Vicodin™.
Not to be confused with the more severe symptoms of an allergic reaction, side effects and adverse reactions do commonly occur with use of the drug, such as drowsiness, nausea, vomiting, and constipation. Some people also report mood alterations, a lightheaded feeling, and retention of urine. Often prescribing a laxative along with Vicodin™ to counteract constipation, doctors suggest increasing dietary fiber and water intake, as well as moving slowly to a rising position to prevent dizziness. Certain side effects are considered to be serious and contacting a doctor is necessary if seizures occur or breathing becomes faint and shallow.
Stopping medication administration is the most significant step in treating allergic reactions to drugs. For the hives, itching, and breathing issues, a corticosteroid injection may be given, or, in cases where the reaction is not life-threatening, an antihistamine such as diphenhydramine can be used. It is important to consult a physician before taking any drug to counteract a suspected allergic reaction to medication. When preventing future allergic reactions to medicines, it is essential to notify the physician of any known drug allergies and to avoid taking any derivatives of a drug to which a reaction has occurred in the past.
