1. Skin Rashes
One of the foremost symptoms of an antidiarrheals allergy could be skin rashes. These could appear as red, itchy patches on any part of the body and can cause significant discomfort.
2. Difficulty in Breathing
This symptom involves a feeling of tightness in the chest, shortness of breath, or wheezing. It happens because the airways of the body can narrow down due to an allergic reaction.
3. Swelling
Swelling of various body parts, particularly the face, lips, tongue, or throat, can also occur. It can be visually noticeable and may also cause a choking sensation if the throat or tongue swells up.
4. Dizziness
This symptom can make a person feel light-headed, unsteady, or about to faint. It is a result of decreased blood flow to the brain due to the body's allergic reaction.
5. Rapid Heartbeat
This symptom presents as an accelerated heart rate that is noticeably faster than the individual's regular heartbeat. It can cause a feeling of fluttering or pounding in the chest.
6. Nausea or Vomiting
Nausea is a feeling of sickness with a tendency to vomit. An allergic reaction may cause the stomach to churn, leading to nausea or even vomiting. This is the body's way of getting rid of any allergic substance.
