If you have a physical reaction after consuming garlic or its products, you may have a garlic allergy. Interestingly, garlic is part of the lily family; so if you suffer from a garlic allergy, you may also be allergic to onions, leeks, chives, and shallots.

Alternatives To Garlic
Garlic Allergy Symptoms
- Contact dermatitis
- Hives or garlic allergy rash
- Swelling of the lips or tongue
The most common symptoms of a garlic allergy are asthma and contact dermatitis. Very rarely does a garlic allergy result in more severe symptoms. You could also just have a garlic intolerance. In this case, symptoms will be mild including heartburn or stomach cramps. Sometimes an allergy can be confused with an intolerance, so it’s important to visit a food allergy specialist for a diagnosis. If you experience the above symptoms after eating garlic, seek medical treatment immediately.
Garlic Allergy Diagnosis
An oral food challenge and elimination diet are the only accurate garlic allergy testing to diagnose a garlic allergy sensitivity. During a food challenge, your allergist will expose you to garlic in a clinical setting to see if it causes an allergic reaction. Food challenges can be dangerous so, they are only performed in a clinical setting with trained medical personnel. Your doctor will hand emergency medical equipment on hand to treat any symptoms that may occur.
In contrast, an elimination diet requires you to refrain from eating garlic and its products to see if your garlic allergy reaction subsides. During this time, it’s helpful to keep a food journal and keep track of what you’re eating. Elimination diets usually last for about two weeks. This is the safer option of the two and your allergist will suggest an elimination diet if they suspect a severe allergic reaction will arise during a food challenge. After the allotted time, your allergist will determine if it’s safe to continue eating garlic or if you need to eliminate it from your diet entirely.
Garlic Allergy Treatment
The best treatment for garlic allergy is avoidance. When dining out, tell restaurant staff about your allergy to make sure that no pre-made foods or sauces contain garlic. Use alternative spices to flavor your food.
Most cases of garlic allergies are mild and can be treated with antihistamines, so it’s helpful to keep them with you. Over the counter medications may be strong enough, but you can also get prescribed medications to treat your symptoms. Prescribed medications are necessary for asthma and some case of contact dermatitis. If you suffer from allergic asthma, your allergist will recommend an inhaled corticosteroid.
For more serious allergic reactions to garlic, ask your allergist about an epinephrine injection like Auvi-Q or Epipen. You should carry your epinephrine to treat symptoms related to anaphylaxis. Train your friends and family how to administer the medication in case you can’t do it yourself.
