When is the best time to take metoprolol?

Your Dr. will probably has prescribed this medication before you go to bed because it may make you dizzy.
Follow your prescriber´s instructions and as your organism adjusts and gets used to the medication you can take it in the morning if you feel well/safe. It is important to take the medication everyday at the same time for an even amount of the medication to remain in your system, also, take it with food or right after a meal.
