Hello – Obviously we’re not docs here, but if a patient is symptomatic *and* out of range, it seems like the doc should at least be willing to have a discussion about making a dose change!
If this doc is someone you’ve been happy with in the past, it might be worth scheduling a followup to have this discussion in person and try to preserve the relationship. If you just don’t think this doctor is taking your husband’s concerns seriously at all, then getting a second opinion would be a good idea.
