Swelling
If a patient is experiencing an allergic reaction to anticoagulants, they may develop swelling. This can occur in various parts of the body, such as the face, lips, tongue, fingers, or lower legs. It is essential to seek medical attention immediately.
Rash or hives
Rashes or hives are common allergic reactions to anticoagulants. These red, itchy, and raised welts on the skin are triggered by your body's reaction to the medication.
Difficulty Breathing
Someone allergic to anticoagulants may experience difficulty breathing. This could range from a tightness in the chest, wheezing, or shortness of breath. This symptom can indicate a severe allergic reaction known as anaphylactic shock, which requires immediate medical attention.
Dizziness
Feeling faint or experiencing dizziness can be a sign of an allergic reaction to anticoagulants. This should not be ignored, as it could be a signal of low blood pressure, linked to severe reactions.
Nausea or Vomiting
Nausea or vomiting may occur in response to the body rejecting the anticoagulant medication. While this symptom can also be a side effect of the medicine itself, extreme, prolonged, or acute onset nausea and vomiting should be investigated for a possible allergic response.
Fast Heart Rate
An accelerated heart rate or palpitations can be a symptom of an allergic reaction to anticoagulants. Tachycardia, or rapid heart rate, can indicate that the body is fighting off a substance it views as harmful, and this could be a sign of a serious allergic reaction.
