A drug allergy happens when your immune system reacts to a drug that you have come into contact with — including prescription drugs, over-the-counter medications, or herbal supplements. A drug allergy is different from a drug side effect.
A latex allergy occurs when your immune system reacts to proteins in natural rubber latex from rubber trees. Allergic reactions to latex can happen from touching products that contain latex, such as gloves, condoms, or balloons, or from inhaling latex particles released into the air by these products.
UPMC specialists provide comprehensive treatment for latex allergies and allergies to drugs or medications. We offer a full range of diagnostic and treatment services to help you understand and manage your latex allergy or drug allergy.

What Are Drug and Latex Allergies?
A drug allergy occurs when your body has an immune reaction to a drug — including prescription or over-the-counter medications and herbal supplements — that you come into contact with or ingest. A drug allergy is different from a drug side effect.
A latex allergy occurs when your body has an immune reaction to proteins found in natural rubber latex that comes from the rubber tree. Allergic reactions to latex can be triggered by touching products that contain latex, such as gloves, condoms, or balloons, or by inhaling latex particles released into the air by these products.
What are the types of drug and latex allergies?
A drug allergy is a reaction that involves your immune system. It is different from a medication side effect or adverse reaction.
There are two types of latex allergies:
- Contact dermatitis — A delayed allergic reaction.
- Immunoglobulin E (IgE)-mediated reaction — An immediate allergic reaction that involves your immune system.
How common are drug and latex allergies?
Although side effects to medications are common, true drug allergies are rare. According to the Asthma and Allergy Foundation of America (AAFA), only 5% to 10% of reactions to drugs are genuine allergic reactions.
Latex allergies are also uncommon. According to the AAFA, latex allergy affects 4.3% of the general population. It is more common among people who have frequent exposure to latex, such as health care workers.
What causes drug and latex allergies?
Drug allergies occur when your immune system mistakenly identifies a medication as a harmful substance, triggering an allergic reaction.
Common triggers for drug allergies include:
- Anesthetics.
- Antibiotics containing sulfonamides (sulfa drugs).
- Anticonvulsant medications.
- Chemotherapy drugs.
- Dyes used for imaging tests.
- Over-the-counter pain relievers, such as aspirin, ibuprofen, and naproxen.
- Penicillin and other related antibiotics.
Latex allergies occur when your immune system reacts to proteins found in natural rubber latex that comes from the rubber tree. It can occur when your skin comes into contact with latex, or when you inhale latex fibers.
You can develop latex allergies later in life, especially after frequent exposure to products containing latex.
Common triggers for latex allergies include:
- Balloons.
- Bandages.
- Catheters.
- Condoms.
- Elastic in clothing.
- Medical gloves.
- Rubber balls.
- Rubber bands.
- Rubber gloves.
Drug and latex allergy risk factors
Anyone can have an allergic reaction to latex or a drug. However, you may be at a higher risk if you have other allergies or a personal or family history of drug or latex allergies. Frequent or prolonged exposure to latex or a drug could increase your risk of developing an allergy.
Complications of drug and latex allergies
People who are highly sensitive to latex or certain medications could experience a potentially life-threatening reaction called anaphylaxis. Anaphylaxis can cause dizziness, a sharp drop in blood pressure and, in some cases, loss of consciousness, shock, or cardiac arrest.
How can I prevent drug or latex allergies?
Although there is nothing you can do to prevent the allergy itself, you may be able to prevent allergic reactions by taking steps to avoid exposure to allergy-causing drugs or latex and following your doctor’s advice regarding allergy treatment.
What Are the Signs and Symptoms of Drug and Latex Allergies?
Symptoms of drug allergies are caused by your body’s immune reaction to the drug.
Symptoms, which can range from mild to life-threatening, may include:
- Coughing.
- Difficulty breathing.
- Hives or skin rash.
- Hoarse voice, tightness in the throat, or difficulty swallowing as a result of swelling in the throat or tongue.
- Itching.
- Itchy, watery eyes.
- Nausea or vomiting.
- Runny nose.
- Sneezing.
- Swelling
- Wheezing.
Anaphylaxis caused by drug and latex allergies
The most serious type of allergic reaction is called anaphylaxis, which can occur within minutes and is potentially life-threatening. Anaphylaxis causes dizziness, a sharp drop in blood pressure and, in some cases, loss of consciousness, shock, or cardiac arrest.
When should I see a doctor about my drug or latex allergy symptoms?
If you have drug or latex allergy symptoms, you should schedule an appointment with your doctor right away.
Anaphylaxis is a medical emergency. If you have symptoms of anaphylaxis, dial 911 or go to the nearest hospital Emergency Department.
How Do You Diagnose Drug and Latex Allergies?
To diagnose drug and latex allergies, your doctor will perform a physical exam and review your symptoms and medical history. Your doctor may order tests to help make a diagnosis.
What to expect during your visit
During your visit, your doctor will:
- Ask about your symptoms.
- Evaluate your medical history.
- Order tests.
- Perform a physical exam.
Tests to diagnose drug and latex allergies
Tests to diagnose drug and latex allergies include:
- Blood tests — Blood tests measure the amount of immunoglobulin E (IgE) antibodies in your blood that are specific to certain allergens and can be used to diagnose latex allergies.
- Oral drug challenge — A test to confirm or rule out a drug allergy. During the test, you will be given a small, gradually increasing amount of a suspected allergy-causing drug under medical supervision and be monitored for signs of an allergic reaction.
- Patch testing — Involves placing patches with latex on your skin to detect delayed allergic reactions that occur hours or days after exposure.
- Skin testing — Skin testing, also called scratch testing, exposes your skin to small amounts of allergy-causing substances (allergens) and can identify allergy triggers.
Drug and latex allergy prognosis
Your prognosis with a drug or latex allergy depends on the severity of your allergy. People with minor reactions may be able to manage their condition with medication and avoidance of allergy triggers. However, people who experience life-threatening allergic reactions may need to take additional precautions, such as carrying an epinephrine injector to use if anaphylaxis occurs.
How Do You Treat Drug and Latex Allergies?
The goals of drug and latex allergy treatment are to reduce symptoms, lower your risk of life-threatening allergic reactions, and improve quality of life. Drug and latex allergy treatment options include:
Allergy medications
Some medications may be able to help control mild allergic reactions to medications or latex, but may not be suitable if you have a severe or life-threatening allergy. Before you use any allergy medication, ask your doctor if it is right for your condition and symptoms.
Epinephrine
If you are at risk of experiencing a severe or life-threatening allergic reaction called anaphylaxis, your doctor may prescribe an injectable emergency medication called epinephrine. Epinephrine is usually given at the first sign of a severe allergic reaction, followed by emergency medical treatment. Your doctor will provide specific instructions on when and how to use epinephrine.
