Ardic 100mg Tablet is used to relieve pain and inflammation associated with migraine, muscle pain, dental pain, rheumatoid arthritis, ankylosing spondylitis, osteoarthritis, gout, strain, and sprain. It contains Diclofenac, which works by blocking the effect of an enzyme called cyclo-oxygenase (COX) that produces prostaglandins responsible for pain and inflammation. Thereby, it provides relief from pain and inflammation. It may cause certain side effects such as stomach pain, heartburn, nausea, vomiting, diarrhea, indigestion, loss of appetite, headache, and dizziness. Before taking this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions.
