The use of Velaxin prepat may cause the occurrence of so-called angioedema. This is a type of allergic reaction involving swelling of tissues located deeper under the skin. It often covers the facial area. Swelling is usually spilled and requires consultation with a doctor. I encourage you to urgently consult your doctor. In the case of severe oedema, the use of preparations should be discontinued or returned to a lower dose until the visit to the doctor.
