Flaxseed oil is derived from flaxseeds and is commonly used as a dietary supplement. Although flaxseed oil is generally considered safe, some people may experience an allergic reaction to it. The symptoms of a flaxseed oil allergy can vary, but common symptoms include:
Skin reactions: Itching, redness, hives, or swelling of the skin.
Respiratory symptoms: Sneezing, runny nose, or difficulty breathing.
Digestive symptoms: Nausea, vomiting, diarrhea, abdominal pain, or bloating.
Anaphylaxis: In severe cases, anaphylaxis, a life-threatening allergic reaction, may occur, causing symptoms such as a rapid heartbeat, confusion, or loss of consciousness.
If you have a history of allergies or have experienced an allergic reaction to flaxseed or other seeds, it's best to talk to your doctor before taking flaxseed oil, and to seek medical attention if you experience any symptoms of an allergic reaction.
