Guanfacine ER

When and How to Take Guanfacine ER

Some general considerations with guanfacine ER to keep in mind include the following:
  • Guanfacine ER comes in the form of an extended-release tablet. It is taken by mouth, usually once a day.
  • Do not crush, chew, or break the tablets, as this will cause the medication to be released too quickly. The tablets must be swallowed whole.
  • Guanfacine ER can be taken with or without food. However, it should not be taken with a high-fat meal, as this increases the absorption of the medication too much, which could lead to overdose symptoms.
  • Try to give this medication at the same time each day.
  • For the medicine to work properly, it must be taken as prescribed. Guanfacine ER will not work if your child stops taking it.

Dosing Information

The dose of guanfacine ER your child's healthcare provider recommends will vary, depending on a number of factors, including:
  • How your child responds to guanfacine ER
  • Other medications your child may be taking
  • Other medical conditions your child may have.
As always, do not adjust your child's dose unless the healthcare provider specifically tells you to do so.
