Question: What are the treatments for Cramp-fasciculation syndrome ?
Answer: How might cramp-fasciculation syndrome be treated? There is limited information in the medical literature about the treatment of cramp-fasciculation syndrome (CFS). Much of what is available describes individual cases. Some people with CFS improve without treatment. Treatment with carbamazepine, gabapentin, or pregabalin (medications that reduce the hyper-excitability of nerves) was described as helpful in improving symptoms in individual cases. Immunosuppressive therapy (e.g., prednisone) has been used to treat cases of CFS that did not respond to other treatments. For severe cases, additional treatment options may be considered. Decisions regarding treatment should be carefully considered and discussed with a knowledgeable healthcare provider.
