If you take Ofev capsules more than usual, it’s important to contact your doctor immediately. Taking more than the recommended dose of Ofev can increase the risk of side effects, such as diarrhea, nausea, vomiting, liver problems, decreased appetite, headache, weight loss, and high blood pressure. In some cases, taking too much Ofev can be dangerous and may require medical attention. It’s important to follow the recommended dosage of Ofev and not make any changes to the dosage without consulting a doctor.
