Rashes or Hives
One of the most common symptoms of an antimalarial allergy is the appearance of skin rashes or hives. These are often characterized by red, itchy spots or raised bumps on the skin.
Swelling
In some severe cases, patients allergic to antimalarials can experience swelling. This can occur on any part of the body but is particularly common on the face, lips, tongue, or throat.
Difficulty Breathing
If an allergy turns severe, the patient may experience difficulty breathing, a condition known as anaphylaxis. This requires immediate medical attention as it can become life-threatening.
Nausea or Vomiting
Some individuals may also experience gastrointestinal issues such as nausea or vomiting if they have an allergy to antimalarials.
Dizziness or Fainting
Dizziness or fainting is also a common symptom of an antimalarial allergy. This is caused by a sharp drop in blood pressure.
Fever
A fever is another sign of an allergic reaction to antimalarials. It's the body's response to the foreign substance and is usually accompanied by other symptoms like chills and weakness.
