Dioctahedral smectite is used to treat:
It works by forming a protective layer in your stomach and intestine walls, making them stronger against harmful agents.
Diarrhoea can cause loss of fluids and salts from the body, and taking this medication on its own does not replace the fluid and salt loss. Ensure you continue to take sufficient fluid and oral rehydration salts to prevent dehydration and electrolyte imbalance.
How to prepare and take dioctahedral smectite:
Note: Dioctahedral smectite should not be used in infants and children under 2 years of age.
This medication may be taken when required for a short period of time. This means that you may stop taking the medication when you no longer have symptoms.
Inform your healthcare professional if:
In children 2 years and above, acute diarrhoea should be treated together with early oral rehydration to avoid dehydration. Long-term use of dioctahedral smectite should be avoided.
If your symptoms do not improve within 7 days, consult your doctor.
If you have any questions about this medication, please discuss with your healthcare professional.
As dioctahedral smectite may affect how other medications are absorbed by the body, avoid taking other medications at the same time as this medication. If you are taking other medications, please ensure that you space apart the administration with other medications for at least 2 hours.
