Difficulty Breathing
One of the critical symptoms of an opioid allergy could be difficulty in breathing. The person may experience shortness of breath or even severe conditions like respiratory distress or asthma, depending on the severity of the allergic reaction.
Hives or Rash
Physical symptoms such as hives, skin rash, or itching are commonly associated with allergies, including opioids. The skin may become red, inflamed, and uncomfortable, often showing up shortly after taking the drug.
Swelling of Your Face, Lips, Tongue, or Throat
This symptom includes swelling of soft tissues, including the face, lips, tongue, or throat. This could be a sign of a severe allergic reaction and can potentially interfere with breathing if the throat swells significantly.
Nausea and Vomiting
From an allergy to opioids, a patient may experience gastrointestinal symptoms. This can include feeling nauseous or vomiting, which can be distressing and debilitating for the individual experiencing it.
Dizziness or Fainting
Dizziness, lightheadedness, or even fainting can be an indication of an opioid allergy. It usually stems from a decrease in blood pressure, which can be a serious symptom requiring immediate medical intervention.
Fast Heartbeat
A fast or irregular heartbeat, known as tachycardia, is another potential symptom of an opioid allergy. This can cause feelings of unease, shortness of breath, and chest pain, and immediate medical attention is necessary.
