Post-marketing surveillance is still ongoing What we do know from available research and patient reports: Musculoskeletal side effects (which include muscle cramps) were reported in clinical trials, though at lower rates than gastrointestinal effects Patient forums and post-marketing reports suggest cramping occurs in some patients, particularly during the early weeks of treatment The side effect may be dose-related, with potentially higher incidence at higher doses What patients tend to report about the cramping timeline: Experiences vary widely, but patients in online communities and support groups often describe a pattern where: Cramping tends to first appear within the first 1-2 weeks of starting treatment Many find cramps feel most noticeable around weeks 2-3 A gradual improvement is commonly reported around weeks 4-6 By weeks 8-12, many (though not all) patients report their cramping has significantly improved or resolved Keep in mind that your experience may differ considerably from these general observations
