Adverse drug reactions (ADRs) are unintended and often unexpected changes in a person's health caused by exposure to a medication, medical device, or substance. These reactions can be caused by various factors, including improper dosage, concomitant medications, underlying medical conditions, and drug interactions.
Examples:
Taking high doses of aspirin for pain relief can increase the risk of stomach bleeding.
Taking blood thinners with alcohol can increase the risk of bleeding complications.
Using certain medications, such as chemotherapy drugs, can suppress the immune system, making people more susceptible to infections.
Taking antidepressants can cause insomnia and other side effects.
Allergic reactions to medications like penicillin and aspirin are also considered ADRs.
Consequences of ADRs:
ADRs can range from mild to life-threatening. Some common ADRs include:
Increased heart rate and blood pressure
Headache
Nausea and vomiting
Diarrhea
Rash
Dizziness
Confusion
Loss of consciousness
Identifying ADRs:
ADRs are typically recognized through a patient's medical history and a physical examination. Healthcare professionals pay close attention to the patient's symptoms and may ask about their medications and medical conditions.
Preventing ADRs:
The best way to prevent ADRs is to take medications correctly and avoid taking multiple medications that interact with each other. It is also important to inform healthcare professionals about any underlying medical conditions or allergies.
Treatment for ADRs:
The treatment for ADRs depends on the cause and severity of the reaction. Treatment may include discontinuing the medication, managing symptoms, or providing supportive measures such as rest and fluids. In some cases, hospitalization or emergency treatment may be necessary
