Dr. Liao Huiling reply Pharmacology


Mei Mei: Hello! The medications that both children are taking are actually similar; they both contain steroids and cough expectorants.
If the younger sister took the older sister's medication, there should be no issues, so please rest assured.
Since our role does not specifically focus on online medication consultation services, we are unable to respond to your inquiry as promptly as you might expect.
We apologize for this.
If you have urgent medication-related questions, I recommend calling the original healthcare facility for assistance, as they will likely resolve your concerns more quickly.
Wishing you and your family safety!

More Info


When a child accidentally ingests medication intended for another person, particularly when the medications differ in dosage and purpose, it can lead to serious health risks. In this case, the older sister was prescribed Bisolvon (a mucolytic agent) and Metisone (a corticosteroid), while the younger sister was prescribed Prednisolone (another corticosteroid) and Bisolvon. The younger sister, aged 5, mistakenly consumed her sister's medication, which raises several concerns.


Potential Risks and Effects
1. Bisolvon (Bromhexine): This medication is generally used to help clear mucus from the airways. While it is considered safe for children, taking an excessive dose can lead to side effects such as gastrointestinal disturbances, nausea, vomiting, and diarrhea. In rare cases, it may cause allergic reactions, which can manifest as skin rashes or respiratory issues.

2. Metisone (Methylprednisolone): This is a corticosteroid used to reduce inflammation and suppress the immune response. In children, corticosteroids can have significant effects, especially if taken inappropriately. Side effects may include increased appetite, mood changes, sleep disturbances, and potential impacts on growth and development. If the younger sister ingests Metisone, she may experience these side effects, particularly if the dosage is higher than what is safe for her age and weight.

3. Prednisolone: Similar to Metisone, Prednisolone is also a corticosteroid. If the younger sister has taken her sister's Metisone instead of her prescribed Prednisolone, she may not experience immediate adverse effects, but the risk of side effects still exists, especially if she consumes a higher dose than intended.


Immediate Actions to Take
- Contact Poison Control or Emergency Services: Given the potential for serious side effects, it is crucial to contact your local poison control center or seek immediate medical attention. They can provide specific guidance based on the amount ingested and the medications involved.

- Monitor for Symptoms: Keep an eye on the younger sister for any signs of adverse reactions, such as unusual behavior, gastrointestinal distress, or allergic reactions. If any concerning symptoms arise, seek medical help immediately.

- Provide Information: When contacting medical professionals, provide them with detailed information about the medications involved, including dosages and the time of ingestion. This information will help them assess the situation more accurately.


Preventive Measures
To prevent such incidents in the future, consider the following strategies:
- Medication Storage: Always store medications out of reach of children and in clearly labeled containers. Consider using child-proof locks on cabinets where medications are stored.

- Education: Teach children about the importance of not taking medications that are not prescribed to them. This can help them understand the risks associated with medication misuse.

- Regular Review: Regularly review the medications in your household, ensuring that they are still needed and that children understand which medications are theirs.

In conclusion, while the immediate risks associated with the younger sister taking her sister's medication can vary, it is essential to act quickly and seek professional medical advice. Monitoring for symptoms and ensuring proper medication management can help mitigate risks and ensure the safety of children in the household.
