Any medication with the letter ER, XL, XT, etc. Stand for extended release and should never be broken, scored or not. It releases small amounts of the medication in your system over a 24 hour period and that is the way the doctor wants you to take it. To break the coating would give you the dose right away. It could over tax your body and leave you with out enough medication in your system for 24 hours.
Regardless of the dose never do you cut an ER medication in half. The ER before the Metoprolol means EXTENDED RELEASE.
By cutting the medication in half your body will breakdown the medication immediately rather than it's intended form which is extended release.
