 | Codeine is habit forming. It is possible to become physically and/or psychologically dependent on the medication. Do not take more than the prescribed amount of medication or take it for longer than is directed by your doctor. Withdrawal effects may occur if codeine and guaifenesin is stopped suddenly after several weeks of continuous use. Your doctor may recommend a gradual reduction in dose. |
Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.
