How should I take senna?
When considering the use of herbal supplements, seek the advice of your doctor. You may also consider consulting a practitioner who is trained in the use of herbal/health supplements.
If you choose to use senna, use it as directed on the package or as directed by your doctor, pharmacist, or other healthcare provider. Do not use more of this product than is recommended on the label.
You must chew the chewable tablet before you swallow it.
Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
Senna should produce a bowel movement within 6 to 12 hours after you take it.
Do not use different formulations of senna (such as tablets and liquid) at the same time without medical advice. Using different formulations together increases the risk of an overdose of senna.
Senna may be unsafe when taken long-term or in high doses. Using senna for longer than 2 weeks may cause your bowels to stop functioning normally. Long-term use may also cause a serious electrolyte imbalance. Certain electrolyte imbalances can cause muscle weakness, heart problems, liver damage, and other harmful effects.
Call your healthcare provider if your constipation does not improve after 1 week of using senna, or if constipation gets worse.
Store at room temperature away from moisture, heat, and light.
