Fibnib 100 Softgel Capsule is used to treat idiopathic pulmonary fibrosis (a disease that causes scarring of the lungs). It contains Nintedanib, which helps reduce the scarring and swelling in the lungs by decreasing the release/activity of naturally occurring growth factors in the body, allowing you to breathe better. In some cases, this medicine may cause side effects such as nausea, tiredness, diarrhoea, indigestion, loss of appetite, headache, and photosensitivity. Before taking this medicine, inform the doctor if you are pregnant or breastfeeding, taking any other medication, or have any pre-existing medical conditions.
