Aceclofenac 100mg capsules are a type of non-steroidal anti-inflammatory drug (NSAID) used to relieve pain and inflammation. They work by blocking the production of prostaglandins, which are substances that cause pain, swelling, and inflammation. Aceclofenac 100mg capsules are commonly prescribed for conditions like osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. They can also be used to treat mild to moderate pain, such as headaches, backaches, menstrual pain, and sprains. Aceclofenac 100mg capsules are typically taken twice a day, with or after food. It is important to take the medicine as prescribed by your doctor and to avoid exceeding the recommended dose. Like all medications, aceclofenac 100mg capsules can cause side effects, such as nausea, vomiting, diarrhea, and stomach pain. It is important to talk to your doctor if you experience any side effects.
