Allergic Reaction to CBD Oil: Can You Get Allergies From It?

If you are new to CBD oil, it can be difficult to know when something is wrong. This is because the side effects of CBD oil are not usually that intense. However, if you feel like your allergic reaction is caused by CBD oil, you need to look out to make an accurate diagnosis.

Can You Be Allergic to CBD?

While it is rare, most people can have a negative reaction to CBD oil. Allergic reactions are usually caused by the chemical compounds in the hemp plant that produce CBD oil and its extracts. These oils can cause contact dermatitis or other skin irritations if they come into contact with your skin. If you notice any of these symptoms after using CBD oil, then you should discontinue use immediately.

You would know if you are allergic to CBD oil when you experience unusual effects from it. These effects include:

  • Severe skin irritation
  • Hives, bumps, or redness on the skin. This is usually caused by an allergic reaction to CBD oil. It can also be a symptom of atopic dermatitis, which is a type of eczema that causes intense itching and irritation in your skin.
  • Swelling of the throat and face

These are all signs that you should stop using CBD oil. If your symptoms worsen, then it is best to seek medical attention immediately.

Adverse Effects of CBD Oil

Taking CBD oil can bring varied side effects. Generally, CBD oil has very few side effects. However, in case you are having an allergic response to the chemical compounds in CBD oil, then it may cause mild skin irritations or even more severe problems such as swelling and swelling of sensitive parts of your body.

Other side effects could be:

  • Dry Mouth: CBD oil can cause your mouth to feel dry and parched. This is common and usually goes away after a few days of treatment.
  • Nausea or Vomiting: Some people have reported feeling nauseous or even throwing up when taking CBD oil, but this side effect typically only occurs in high doses.
  • Headaches: Some people have reported having mild headaches after taking CBD oil. This is usually caused by an increase in blood flow to the brain, which can be good for you but may cause some discomfort initially.
  • Drowsiness or Dizziness: If you are not used to CBD oil and take too much at once, it can cause you to feel drowsy or dizzy. This is common and usually goes away after a few days of treatment.
  • Allergic Reactions: If any of these symptoms occur, then it could be an allergic reaction that you are experiencing from the CBD oil. These types of reactions can cause swelling and inflammation in your skin which can lead to itching, rashes, and hives.

What Happens If You are Allergic to CBD Oil?

If you are allergic to CBD oil, then it is important for you not only to stop taking CBD but also to see your doctor as soon as possible. If your allergies get worse or affect other parts of the body like respiratory problems or loss of consciousness, then that can be a sign that something more serious is going on and may need immediate medical attention.

You can also notice physical signs that you have an allergic reaction to CBD oil. These can include:

  • Skin Rash or Hives
  • Swelling of the Face, Lips, and Throat Area

Allergic reactions are unpleasant, but fortunately, they are not too common. If you have newly started taking CBD oil and have seen any of the indications above, then it is better to stop using CBD straight away to avoid additional side effects or an allergic reaction that could be more severe.

How are Allergic Reactions to CBD Oil Diagnosed?

As with any other allergy, the only way to accurately diagnose an allergic reaction is by asking your doctor about your symptoms and getting a medical examination. Your doctor may ask you questions about what medications you are taking or how often CBD oil has been used before providing their diagnosis.

If allergies do seem like they could be affecting you, then there are a few tests your doctor can run to determine if you are having an allergic reaction. These include:

  • Skin Test: a small portion of CBD oil is applied directly to the skin and then observed for any reactions after 15 minutes. This test will tell how likely you are to have allergies to CBD oil and help narrow down what kind of symptoms you may be experiencing.
  • Blood Test: a small amount of CBD oil is injected under the skin and then observed for any type of allergic reaction over time. This test will tell your doctor what kind of allergies you may have to CBD oil, but it cannot determine how likely they are to occur or when an attack could happen in the future.

If you have been taking CBD for quite some time, you will know instantly if you are having uncommon effects from it. New users, can only identify if it is an allergic reaction they are having if they seek consultation from their doctors. Usually, reactions first appear on the skin.


Some people find it easy to know if they are having an allergic reaction to CBD oil. Others may not be able to tell if they are allergic until a more serious problem happens, like swelling and inflammation in sensitive parts of the body.

If you have been experiencing any symptoms above or even just some mild side effects from CBD oil, then it is best to stop taking CBD immediately so that an allergic reaction does not occur. If you are concerned about an allergy, then you should see your doctor as soon as possible and tell them what kind of side effects you have been experiencing.
