Serious side effects and what to do
Serious side effects and what to do
A lack of effect (your medication not working) is a possible and serious side effect associated with Kovaltry. Should this happen, contact your healthcare professional.
If you experience tightness in the chest or a general feeling of being unwell, hives, dizziness and nausea or feel faint upon standing, you may be experiencing a rare severe sudden allergic reaction (a so-called anaphylactic reaction) to Kovaltry. If these uncommon but serious hypersensitivity reactions occur, stop taking Kovaltry and seek immediate medical attention.
