Hi, Leg spasms and chills can be side effects of Tegretol (carbamazepine), and it s important to talk to your doctor about these symptoms to determine if they are related to the medication or if there is another underlying medical condition. However, here are some general tips that may help manage your symptoms: * Stretching and exercise: Gentle stretching exercises can help alleviate muscle spasms, particularly those in the legs. Walking or light exercise may also help improve circulation and reduce chills. * Massage therapy: Massage can help reduce muscle tension and increase blood flow, which may help alleviate leg spasms. * Heat therapy: Applying heat to the affected area, such as a warm compress or heating pad, can help relax muscles and reduce spasms. * Stay hydrated: Dehydration can contribute to muscle spasms, so it s important to drink plenty of fluids throughout the day. * Maintain a healthy diet: Eating a balanced diet with plenty of fruits and vegetables can help provide the nutrients your body needs to function properly and may improve energy levels. Talk to your doctor: If you re experiencing side effects from Tegretol, your doctor may be able to adjust your dosage or switch you to a different medication. It s important to work with your doctor to find a treatment plan that works best for you and to discuss any concerns or symptoms you may be experiencing. Take care.
