Metamucil making my constipation worse. what should i do?

Its not : Supposed to. You should be taking about 20-30 gms a day. If you are not tolerating it well you can switch to another brand such as citrucel or konsyl. You can also take a stool softener and keep in mind to drink a lot of fluids, specially in this warm weather. If symptoms dont improve talk to your family doc as you may need workup to rule out other causes of constipation.
