The nurse injector reports that the patient female, was injected with revanesse versa+(with lidocaine) 1.2ml in the lips on (b)(6) 2020.No pain or nodularity is experienced.The clinic plans to dissolve the filler in the follow- up visit with the patient.The clinic used a 4% lidocaine topical anesthetic prior to injection.Medical history reported and the patient is not on any medications.She has received ha fillers for the past 3 years (juvederm).The review of a medical doctor was sought by prollenium regarding this case.He believes that recurrent swelling of the lips which resolves with or without treatment suggest an allergic reaction such as angioedema.The most common reasons for this type of reaction is an allergy to foods ( nuts, fruit, shellfish, eggs or dairy) or medications ( antibiotics, aspirin, nsais, ace inhibitors).Allergenic substances applied directly to the lips can also cause these reactions ( lanolin, essential oils, cinnamon or niacin derivatives to name a few).Hyaluronic acid fillers are sugar molecules which are less likely to be antigenic ( allergy inducing ).Reactions to ha fillers would also typically occur closer to the day of injection.That being said if the injecting rn and clinic medical director feel that the ha is an offending agent it should be dissolved with hyaluronidase.This may take 3-4 sessions to completely remove the ha filler.A history of potential offending foods or medications should be taken, as well as consideration to referral for allergy testing.A food diary for days reactions occurred may also offer clues.The manufacturer has requested the clinic to inform of any followup activities.
