Anticipated injection-related reactions: Injection-related reactions might occur. These reactions include bruising, erythema, itching, swelling, pain or tenderness at the implant site. Typically resolution is spontaneous within a few days after injection into the skin, and within one week after injection of the lips.
Post marketing adverse event reporting: The frequency of post market adverse event reporting is calculated on the estimated number of treatments performed with the Restylane Skinboosters range of products.
1/10 000 - 1/50 000: Erythema, inflammation, pain/tenderness, papules/nodules, swelling.
1/50 000 - 1/100 000: Bruising, induration.
<1/100 000: Abscess, acne, atrophy/scarring, blisters, dermatitis, discolouration, granuloma, hypersensitivity, infection, ischemia/necrosis, mass, neurological symptoms such as paresthesia, pruritus, rash, reactivation of herpes infection, short duration of effect, telangiectasia, urticaria.
Vascular compromise may occur due to an inadvertent intravascular injection or as a result of vascular compression associated with implantation of any injectable product. This may manifest as blanching, discolouration, necrosis or ulceration at the implant site or in the area supplied by the blood vessels affected.
Isolated rare cases of visual disturbance as a result of inadvertent intravascular injection have been reported. Isolated rare cases of ischemia/necrosis affecting the nose have been reported after injection, especially in patients who had prior rhinoplasty.
In rare cases intradermal lumps have been reported to remain for several months or very rarely, longer than one year.
As for injectable dermal fillers, symptoms of inflammation at the implant site commencing either shortly after injection or after a delay of 2-4 weeks have been reported. In case of unexplained inflammatory reactions infections should be excluded and treated if necessary since inadequately treated infections may progress into complications such as abscess formation. Treatment using only oral corticosteroids without concurrent antibiotic treatment is not recommended. The prolonged use of any medication, e.g. corticosteroids or antibiotics in treatment of adverse events has to be carefully assessed, since this may carry a risk for the patient. In case of persistent or recurrent inflammatory symptoms, consider removal of the product by aspiration/drainage, extrusion or enzymatic degradation (hyaluronidase injections). Before any removal procedure is performed, the swelling may be reduced by using e.g. NSAID for 2-7 days or a short course of corticosteroids for less than 7 days, in order to more easily palpate any remaining product.
For patients who have experienced clinically significant reactions, a decision for retreatment should take into consideration the cause and significance of previous reactions.
Post inflammatory pigmentation changes have been observed in clinical studies in people with dark skin (Fitzpatrick Type IV-VI).
