Loperamide can be used to prevent or treat diarrhoea by slowing down the bowel movements. However, there is an increased risk of side effects if you are taking the wrong dosage. That is why it is important to talk to your doctor or pharmacist about how much you are supposed to take at once and how often it is to be taken. You should follow their directions exactly.
There is different recommended dosage for each kind of diarrhoea you are suffering from. For acute diarrhoea, you should take 4mg following the first stool. Then that needs to be followed up with a maintenance dose of 2mg after each subsequent stool. It is advisable not to take any more than 16mg in a single 24-hour period, though. You should start to notice an improvement by 48 hours, at the latest.
The dosage for chronic diarrhoea is typically 4mg each day, but it can be 8mg, in some cases. You would typically start with a 4mg dose and follow up with a 2mg maintenance dose. You should expect to see an improvement after 10 days.
These are the adult doses, and the doses for children will be different, depending on their age and body weight. It’s always a good idea to consult with a doctor or pharmacist first before giving your child any drug. Take into consideration that medical conditions can necessitate changing the dose, so be sure to tell your doctor or pharmacist about any medical conditions you or the child taking it may have.
If you have blood in your stool or suffer from dysentery, then Loperamide is not recommended. You should talk to a doctor or pharmacist about alternative medicine for treating those conditions.
