What does facial swelling feel like with drug allergy?

Facial Swelling is a very common presentation of Drug Allergy. It may begin after a new medicine or after a medicine taken before without problems. Hives, widespread itching, flushing, rash, lip swelling or a tight throat may occur with it. Some reactions begin quickly, while others develop later. The timing, dose, other medicines and the exact appearance help a clinician judge whether this is an allergy or another medicine-related reaction.

Contact the prescribing clinician promptly for advice about the suspected medicine, and keep the packet or prescription available. Do not take another dose until a clinician or emergency professional tells you what to do, unless it is a medicine that must not be stopped suddenly and you have been given specific instructions. Do not try the medicine again to test it.

Call emergency services immediately for facial swelling with tongue or throat swelling, difficulty breathing or swallowing, wheezing, a hoarse voice, faintness, confusion, repeated vomiting or rapidly worsening symptoms. Use prescribed adrenaline if available and follow its instructions. A reaction that settles still needs medical advice before the medicine is used again.

Ask whether the medicine should be recorded as an allergy, which related medicines to avoid, whether an alternative is needed, and whether you should carry an emergency action plan.
