What should be done after accidentally taking antibiotics?


I had nasal congestion and runny nose for two to three days, thinking it was just my nasal allergies.
Later, I woke up to find my throat swollen and realized I had a cold.
I thought I would just go to the pharmacy to buy over-the-counter medication to relieve my symptoms.
When I informed the pharmacy staff about my symptoms of nasal congestion, runny nose, and sore throat, they provided me with a combination cold medication and mentioned another medication suitable for upper respiratory infections.
I assumed it was a type of cold medicine and took it along with the combination cold medication (Zhongmei Vitamin Cold Capsules).
As a result, I have been experiencing excessive flatulence and diarrhea for the past few days, which I found strange.
Upon further inquiry, I discovered that the medication prescribed by the pharmacy was an antibiotic (Bicillin 625mg).
I would like to ask: I weigh 94 kg and took two pills on the first day, three pills on the second day, and one pill this morning (just now).
I currently have one pill left and am unsure if I have taken an overdose.
I am also concerned that stopping the medication might cause unnecessary consequences.
Should I continue taking it? How many more days should I take it? What should be the daily dosage and interval? Thank you, doctor!

Hello, thank you for your question.
Biaxin is an antibiotic that we commonly prescribe, and it can indeed have diarrhea as a side effect.
If you are only experiencing a cold with a sore throat, without a fever, and your symptoms are improving, you may not need to continue taking the antibiotic Biaxin.
This is a message from the Allergy, Immunology, and Rheumatology Department of Changhua Hospital, Ministry of Health and Welfare, caring for you.

Accidental antibiotic overdoses can be concerning, especially when the medication was not prescribed for your specific condition. In your case, it appears that you mistakenly took an antibiotic (Amoxicillin) that was not necessary for your symptoms, which were likely due to a viral infection, such as a cold. Here’s a comprehensive guide on what to do after an accidental antibiotic overdose and how to manage the situation:

1. Understanding the Situation
First, it’s important to recognize that Amoxicillin is a broad-spectrum antibiotic used to treat bacterial infections. If you were experiencing symptoms of a viral illness (like a cold), taking antibiotics will not help and may lead to unnecessary side effects. You mentioned experiencing gastrointestinal symptoms such as diarrhea and excessive gas, which are common side effects of antibiotics due to their impact on gut flora.


2. Assessing Dosage and Duration
From your description, it seems you took a total of six doses over three days, which may be more than what is typically recommended for a short course of treatment. However, since you only took the antibiotic for a brief period, the risk of severe complications is lower compared to long-term use. Generally, antibiotics should be taken as prescribed, and if you are unsure about the dosage, it’s best to consult with a healthcare professional.


3. What to Do Next
- Stop Taking the Antibiotic: Since you have identified that this medication was not necessary for your condition, you should stop taking it immediately. Continuing to take it could lead to further side effects and contribute to antibiotic resistance.


- Monitor Symptoms: Keep an eye on your symptoms. If your gastrointestinal issues (like diarrhea) persist or worsen, or if you develop new symptoms (such as fever, rash, or severe abdominal pain), seek medical attention promptly.

- Hydration: Ensure you stay well-hydrated, especially if you are experiencing diarrhea. Drinking fluids can help prevent dehydration.


4. Restoring Gut Flora
Antibiotics can disrupt the balance of good bacteria in your gut. To help restore this balance:
- Probiotics: Consider taking probiotics, which can help replenish beneficial bacteria. Foods like yogurt, kefir, sauerkraut, and other fermented products can also be beneficial.

- Diet: Focus on a balanced diet rich in fiber, fruits, and vegetables, which can support gut health.


5. Future Considerations
- Consult a Healthcare Provider: If you have concerns about the effects of the antibiotic or if you experience ongoing symptoms, it’s advisable to consult a healthcare provider. They can provide guidance tailored to your specific situation.


- Avoid Self-Medicating: In the future, be cautious when taking medications without a prescription. Always consult with a healthcare professional or pharmacist if you are unsure about a medication.


6. Potential Long-Term Effects
While short-term use of antibiotics is unlikely to cause permanent damage to your gut flora, repeated or prolonged use can lead to antibiotic resistance and other complications. If you have any concerns about your health or the effects of the antibiotic, a follow-up appointment with a healthcare provider is recommended.


Conclusion
In summary, after an accidental antibiotic overdose, it is crucial to stop taking the medication, monitor your symptoms, stay hydrated, and consider probiotics to restore gut health. Always consult with a healthcare professional for personalized advice and to address any ongoing concerns. Taking antibiotics responsibly is essential to prevent complications and maintain overall health.
