If the medication was vomited, should it be taken again?
Hello Dr.
Hsiao, I have a basic medication question.
If a child vomits shortly after taking medication (especially antibiotics), should they take another dose? Is there a standard procedure for this, such as taking another dose within 30 minutes, but not worrying about it if it’s after 30 minutes? Antibiotics are often emphasized to be taken for the full course! Will vomiting once or twice have any impact? Thank you.

In principle, it is not possible to completely expel the gastric contents immediately after vomiting, so an additional half dose of the medication should be administered.
If vomiting occurs within one hour after dosing, a proportional amount can be supplemented.
If more than two hours have passed, no supplementation is necessary.

When it comes to administering medication to children, particularly antibiotics, it is crucial to understand how to handle situations where a child vomits shortly after taking their medication. This is a common concern among parents, and there are some general guidelines that can help you navigate this situation.
First and foremost, if your child vomits within 30 minutes of taking their medication, it is generally advisable to redose them. This is because the medication may not have had enough time to be absorbed into the bloodstream, and therefore, the intended therapeutic effect may not be achieved. However, if the vomiting occurs after 30 minutes, it is usually recommended not to redose. By this time, the medication is likely to have been absorbed, and giving an additional dose could lead to an overdose.
For antibiotics, completing the full course of treatment is essential to ensure that the infection is fully eradicated and to prevent antibiotic resistance. If your child vomits the medication multiple times, it is important to consult with your healthcare provider. They may suggest alternative methods of administration, such as liquid formulations that may be easier for your child to tolerate, or they might consider adjusting the dosage or switching to a different antibiotic.
In cases where vomiting is persistent, it may indicate an underlying issue that needs to be addressed. For instance, if your child is experiencing nausea due to the medication itself, your doctor might prescribe an anti-nausea medication to help manage this side effect. Additionally, if the vomiting is due to a viral illness or another condition, it may be necessary to treat that underlying issue before resuming the antibiotic therapy.
It is also important to monitor your child for any signs of dehydration, especially if they are vomiting frequently. Ensure they are drinking plenty of fluids to stay hydrated. If your child shows signs of dehydration, such as dry mouth, decreased urination, or lethargy, seek medical attention promptly.
In summary, if your child vomits medication, redose if it occurs within 30 minutes. If it happens after that time, do not redose. Always consult your healthcare provider if vomiting persists or if you have concerns about your child's medication regimen. They can provide tailored advice based on your child's specific situation and health needs. Remember, managing a child's medication can be challenging, but with the right guidance and support, you can ensure they receive the necessary treatment effectively and safely.
