Dealing with Diarrhea from Antibiotics: Tips for Relief - Gastroenterology and Hepatology

Share to:

What should I do if I have been taking antibiotics for a long time and have persistent diarrhea?


Hello Doctor: I have been taking antibiotics (Amoxicillin capsules, 2 capsules every 8 hours) for about a week due to apical periodontitis.
However, the inflammation has not healed, so I need to continue taking them.
Unfortunately, I have been experiencing severe diarrhea, having watery stools almost twice daily.
What should I do? Since the inflammation is still painful and I cannot stop the medication, could you advise me on what I can take to manage the diarrhea caused by the antibiotics? Is taking Loperamide effective for me, or are there other medications I can buy to help with the diarrhea? I'm in pain from my tooth and can't stop having diarrhea; it's really distressing.

Dr. Yuan Hongdao reply Gastroenterology and Hepatology


Hello: You can start by taking over-the-counter antidiarrheal medication.
However, if you experience bloody stools, fever, or abdominal pain, you should consider the possibility of antibiotic-associated pseudomembranous colitis and seek medical evaluation.
Sincerely, Dr.

More Info


Dealing with diarrhea caused by antibiotics can be quite distressing, especially when you're already experiencing pain from an underlying condition like an infected tooth. Antibiotics, such as Amoxicillin, can disrupt the natural balance of bacteria in your gut, leading to diarrhea. This is often due to the elimination of beneficial bacteria that help maintain digestive health, allowing harmful bacteria to flourish. Here are some tips for relief and management of antibiotic-associated diarrhea:
1. Probiotics: One of the most effective ways to counteract antibiotic-induced diarrhea is by taking probiotics. Probiotics are live microorganisms that can restore the balance of gut flora. You can find them in yogurt, kefir, or as dietary supplements. Look for products containing strains like Lactobacillus and Bifidobacterium, which have been shown to be effective in preventing and treating antibiotic-associated diarrhea.

2. Hydration: It's crucial to stay hydrated, especially if you're experiencing frequent watery stools. Drink plenty of fluids, such as water, clear broths, or oral rehydration solutions, to replace lost fluids and electrolytes. Avoid caffeinated and sugary drinks, as they can worsen diarrhea.

3. Dietary Adjustments: While experiencing diarrhea, consider following a bland diet. The BRAT diet (bananas, rice, applesauce, toast) is often recommended as it consists of easy-to-digest foods that can help firm up stools. Avoid high-fiber foods, dairy products, and fatty or spicy foods until your symptoms improve.

4. Over-the-Counter Medications: Medications like loperamide (Imodium) can be used to help reduce diarrhea. However, it's important to consult with your healthcare provider before taking any over-the-counter medications, especially since you are still on antibiotics and experiencing pain from your dental issue. In some cases, if the diarrhea is caused by a more serious infection, stopping the diarrhea may not be advisable.

5. Consult Your Doctor: Since you are still experiencing pain from the dental infection and have been on antibiotics for over a week, it’s essential to follow up with your healthcare provider. They may need to reassess your treatment plan, possibly adjusting your antibiotic regimen or providing additional medications to manage your symptoms.

6. Avoid Self-Medicating: While it may be tempting to try various over-the-counter remedies, it’s best to avoid self-medication without consulting your doctor. Some medications can interact with antibiotics or may not be suitable for your specific situation.

7. Monitor Symptoms: Keep track of your symptoms, including the frequency and consistency of your stools, any accompanying symptoms like fever or abdominal pain, and how long the diarrhea lasts. If you notice blood in your stools, severe abdominal pain, or if the diarrhea persists for more than a couple of days, seek medical attention promptly.

In summary, managing diarrhea from antibiotics involves a combination of dietary changes, hydration, and possibly probiotics. Always consult your healthcare provider before making any changes to your treatment plan, especially when dealing with ongoing pain and infection. They can provide tailored advice and ensure that your dental issue is addressed effectively while managing the side effects of your medication.
