Drug-induced diseases can occur due to a variety of mechanisms, including toxic effects, hypersensitivity reactions, and idiosyncratic reactions. Some drugs can directly damage organs or tissues, while others can interfere with the body’s normal metabolic processes, leading to imbalances or toxic buildup of substances. Hypersensitivity reactions can range from mild rashes to severe, life-threatening conditions such as anaphylaxis.
Idiosyncratic reactions are unpredictable and may occur in a small percentage of patients taking a particular drug, often due to genetic or metabolic differences.
The incidence of drug-induced diseases varies depending on the drug, patient population, and other factors. Some drugs are associated with a high incidence of adverse effects, while others are relatively safe and rarely cause harm.
In general, drug-induced diseases are more common in older adults, as they are more likely to be taking multiple medications and may have underlying health conditions that increase their risk for adverse effects. Additionally, certain patient populations, such as those with liver or kidney disease, may be more susceptible to drug-induced diseases.
According to the Centers for Disease Control and Prevention (CDC), adverse drug events (ADEs) are responsible for an estimated 1.3 million emergency department visits and 350,000 hospitalizations each year in the United States. Additionally, the CDC estimates that ADEs contribute to the deaths of more than 100,000 Americans each year.
List Of Drug-Induced Diseases
The following are some examples of drug-induced diseases:
1. Drug-induced liver injury (DILI): DILI is a common cause of acute liver failure and a leading cause of drug withdrawal from the market.

Symptoms of drug-induced kidney diseases can include swelling, fatigue, and changes in urination patterns.
4. Drug-induced skin diseases: Drug-induced skin diseases can range from mild rashes to severe conditions such as Stevens-Johnson syndrome and toxic epidermal necrolysis. Examples of drugs that can cause skin diseases include antibiotics, anticonvulsants, and nonsteroidal anti-inflammatory drugs (NSAIDs). Symptoms of drug-induced skin diseases can include itching, rash, blisters, and skin peeling.
5. Drug-induced hematologic diseases: Some drugs can cause damage to the blood-forming organs or interfere with normal blood cell production, leading to conditions such as anemia, thrombocytopenia, and agranulocytosis. Examples of drugs that can cause hematologic diseases include chemotherapy agents, anticonvulsants, and certain antibiotics. Symptoms of drug-induced hematologic diseases can include fatigue, weakness, and an increased risk of bleeding or infections.
6. Drug-induced endocrine diseases: Some drugs can interfere with normal hormone production or metabolism, leading to conditions such as diabetes, adrenal insufficiency, and hypothyroidism. Examples of drugs that can cause endocrine diseases include corticosteroids, antipsychotics, and certain chemotherapeutic agents. Symptoms of drug-induced endocrine diseases can include weight gain or loss, changes in appetite, fatigue, and changes in mood.
7. Drug-induced neurologic diseases: Some drugs can cause damage to the nervous system, leading to conditions such as peripheral neuropathy, Parkinson’s disease, and seizures. Examples of drugs that can cause neurologic diseases include certain chemotherapeutic agents, anticonvulsants, and antipsychotics. Symptoms of drug-induced neurologic diseases can include numbness or tingling in the extremities, tremors, and changes in mood or behavior.
8. Drug-induced cardiovascular diseases: Some drugs can cause damage to the heart or blood vessels, leading to conditions such as hypertension, arrhythmias, and heart failure. Examples of drugs that can cause cardiovascular diseases include nonsteroidal anti-inflammatory drugs (NSAIDs), certain chemotherapeutic agents, and some antipsychotics. Symptoms of drug-induced cardiovascular diseases can include chest pain, shortness of breath, irregular heartbeat, and fatigue.
9. Drug-induced gastrointestinal diseases: Some drugs can cause damage to the gastrointestinal tract, leading to conditions such as gastritis, colitis, and pancreatitis. Examples of drugs that can cause gastrointestinal diseases include nonsteroidal anti-inflammatory drugs (NSAIDs), certain antibiotics, and chemotherapeutic agents. Symptoms of drug-induced gastrointestinal diseases can include abdominal pain, nausea, vomiting, and diarrhea.
10. Drug-induced ocular diseases: Some drugs can cause damage to the eyes, leading to conditions such as cataracts, glaucoma, and macular degeneration. Examples of drugs that can cause ocular diseases include corticosteroids, antimalarial agents, and certain chemotherapeutic agents. Symptoms of drug-induced ocular diseases can include blurred vision, eye pain, and changes in color perception.
11. Drug-induced metabolic diseases: Some drugs can interfere with normal metabolic processes, leading to conditions such as hyperglycemia, hyperlipidemia, and electrolyte imbalances. Examples of drugs that can cause metabolic diseases include corticosteroids, antipsychotics, and certain chemotherapeutic agents. Symptoms of drug-induced metabolic diseases can include increased thirst or urination, fatigue, and changes in appetite.
12. Drug-induced autoimmune diseases: Some drugs can trigger an autoimmune response, leading to conditions such as lupus and rheumatoid arthritis. Examples of drugs that can cause autoimmune diseases include hydralazine, procainamide, and certain antibiotics. Symptoms of drug-induced autoimmune diseases can include joint pain, skin rashes, and fatigue.
13. Drug-induced psychiatric diseases: Some drugs can affect mood and behavior, leading to conditions such as depression, anxiety, and psychosis. Examples of drugs that can cause psychiatric diseases include corticosteroids, antipsychotics, and certain chemotherapeutic agents. Symptoms of drug-induced psychiatric diseases can include changes in mood, irritability, and hallucinations.
It’s important to note that not all patients who take these drugs will experience adverse effects. Some drugs are safe and effective for most patients, but for others, they can cause serious harm. Additionally, some drugs can cause multiple types of drug-induced diseases, and the severity of the symptoms can vary widely depending on the patient’s age, health status, and other factors.
If you are experiencing symptoms that you suspect may be related to a medication you are taking, it’s important to talk to your healthcare provider as soon as possible. They can help you determine the cause of your symptoms and recommend a course of treatment or medication adjustment if necessary. It’s also important to follow all medication instructions carefully and report any adverse effects to your healthcare provider promptly.
