Talk:Beta blocker

Hyperthyroidism
I removed hyperthyroidism from the list of contraindications because the source doesn't list it as a contraindication for beta blockers; it says that it can exacerbate hyperthyroid symptoms if discontinued abruptly. Hyperthyroidism is also listed as an indication for beta blockers earlier in the article, so it's contradicting itself.

I also removed the sentence claiming that beta blockers should be used with caution because "tachycardia is a useful monitoring parameter in thyroid disease" because it was uncited and I doubt it's possible to find a citation for this. I'm not sure what kind of doctor would be ok with not treating a patient's abnormally high heart rate because it's a (not very precise) indicator that their thyroid levels are abnormal.

I left the line about abrupt withdrawal possibly causing a thyroid storm because that is in the propanolol document (and added the citation that wasn't there), but it doesn't contraindicate the use of beta blockers to treat hyperthyroidism and shouldn't be in that section. I'm just not sure how to fit it into the Adverse Effects section smoothly. I'm also not sure if it should even be included in the article, since I assume hyperthyroidism is not the only condition for which suddenly stopping beta blockers can be potentially dangerous, but it's the only disorder for which it's mentioned. (And if we're being pedantic, that citation is only for propanolol and not for other beta blockers.)
