Augmentin, a combination of amoxicillin and clavulanate, is a highly effective antibiotic, but it's notorious for causing gastrointestinal side effects, most commonly diarrhea. This occurs primarily for two reasons: the antibiotic kills off beneficial bacteria in the gut, and the clavulanate component can directly speed up gut motility. The disruption of healthy gut flora can also leave an opening for harmful bacteria, such as Clostridioides difficile (C. diff), to flourish and cause more severe, persistent diarrhea. Fortunately, proactive steps can significantly reduce your risk of this unpleasant side effect.
Time your dose correctly to minimize stomach upset
Taking your medication at the right time can have a major impact on its effect on your digestive system. The FDA notes that absorption of the clavulanate part of Augmentin is enhanced when taken at the start of a meal.
- Take with food: Always take your Augmentin dose with a full meal or a substantial snack. This helps buffer the gastrointestinal tract and minimizes the chance of stomach irritation and nausea.
- Consistency is key: Taking the medication at the same time each day with a meal helps maintain a consistent routine and reduces fluctuations in medication levels, which can further irritate the stomach.
Use probiotics to restore gut flora
Probiotics are live microorganisms that can help repopulate the gut with beneficial bacteria that are wiped out by the antibiotic. They are perhaps the most effective tool for preventing antibiotic-associated diarrhea.
- Space your doses: To prevent the antibiotic from killing the good bacteria in the probiotic, take the probiotic supplement at least 2 hours before or after your Augmentin dose.
- Continue after treatment: Your gut microbiome needs time to recover after an antibiotic course. Continue taking probiotics for several weeks after you finish your Augmentin to support this recovery and rebuild microbial diversity.
- Choose the right strains: Research suggests that certain probiotic strains are more effective for preventing antibiotic-associated diarrhea. The most studied and recommended strains are Lactobacillus rhamnosus GG and Saccharomyces boulardii. S. boulardii is a yeast, making it naturally resistant to antibiotics.
Probiotic comparison for antibiotic-associated diarrhea
| Probiotic Strain | Type | Primary Benefit for AAD | Dosage | Key Considerations |
|---|---|---|---|---|
| Lactobacillus rhamnosus GG (LGG) | Bacteria | High efficacy in reducing general AAD risk. | Varies, check product label for colony-forming units (CFUs). | Most studied and often considered the best choice for general AAD prevention. |
| Saccharomyces boulardii | Yeast | Effective in preventing AAD and C. diff-related diarrhea. | Varies, check product label for CFUs. | Naturally resistant to antibiotics; does not need to be separated by hours. |
| Lactobacillus casei | Bacteria | Most efficacious for C. diff-related diarrhea. | Varies, check product label for CFUs. | Specifically targets the prevention of more severe C. diff issues. |
| Multi-strain probiotics | Mixed | Broader gut support; may combine benefits of multiple strains. | Varies widely. | No evidence suggests superiority over single strains for AAD specifically. |
Adjust your diet during treatment
Changing your eating habits while on Augmentin can reduce digestive stress and help manage symptoms.
- Eat bland foods: The BRAT diet (Bananas, Rice, Applesauce, Toast) is a classic for managing diarrhea. These foods are easy to digest and can help bind stools.
- Avoid trigger foods: Stay away from fatty, spicy, high-sugar, and greasy foods, which can exacerbate digestive upset. Limit high-fiber foods temporarily, as they can worsen diarrhea.
- Limit dairy: While some probiotic-rich yogurts can be beneficial, other dairy products can be hard to digest during antibiotic treatment. Opt for non-dairy sources of calcium or use the probiotic supplements mentioned above.
- Steer clear of alcohol and caffeine: Both alcohol and caffeine can irritate the stomach and worsen dehydration, so it's best to avoid them entirely while on Augmentin.
Stay hydrated to prevent dehydration
Diarrhea leads to fluid and electrolyte loss, making dehydration a serious risk. Staying properly hydrated is crucial for your overall health during treatment.
- Drink plenty of fluids: Focus on drinking water, broths, and decaffeinated herbal teas throughout the day.
- Consider electrolyte solutions: For more severe fluid loss, oral rehydration solutions can help replenish lost electrolytes.
When to contact your doctor
While mild diarrhea is a common side effect of Augmentin, certain symptoms warrant immediate medical attention. Always notify your doctor if you experience:
- Severe diarrhea that does not improve
- Blood or mucus in your stool
- Fever along with diarrhea
- Severe abdominal pain or cramping
Do not take over-the-counter anti-diarrheal medications like loperamide (Imodium) without consulting your doctor, as they can sometimes prolong a C. diff infection by slowing the body's ability to eliminate toxins.
Conclusion
Preventing diarrhea when taking Augmentin involves a combination of smart strategies. The most effective approach is to take your medication with food, supplement with a clinically-proven probiotic like Lactobacillus rhamnosus GG or Saccharomyces boulardii, and make temporary dietary adjustments. By proactively managing these common side effects, you can complete your full antibiotic course as prescribed, ensure a successful recovery from your infection, and minimize the impact on your gut microbiome. Remember to consult your healthcare provider with any persistent or severe side effects to ensure proper management.
