What can I take for an upset stomach while on antibiotics?

5 min read

According to the Mayo Clinic, about 1 in 5 people who take antibiotics experience antibiotic-associated diarrhea. If you're wondering what can I take for an upset stomach while on antibiotics?, the answer lies in managing your diet and gut flora balance carefully to minimize discomfort.

Quick Summary

Antibiotics can cause an upset stomach by disrupting gut bacteria. Remedies include probiotics, bland foods, and adequate hydration. Certain medications and foods should be avoided to prevent further irritation or drug interactions. Consult a healthcare provider for severe or persistent symptoms.

Key Points

  • Probiotics are Key: Taking a probiotic supplement, ideally 2-3 hours after your antibiotic dose, helps restore the balance of beneficial gut bacteria and can significantly reduce gastrointestinal side effects like diarrhea.

  • Embrace Bland Foods: A diet of easily digestible foods, such as bananas, rice, applesauce, and toast (the BRAT diet), can soothe an irritated stomach and help manage diarrhea.

  • Stay Well-Hydrated: To combat dehydration from diarrhea or vomiting, drink plenty of water, broth, or oral rehydration solutions to replenish lost fluids and electrolytes.

  • Avoid Certain Medications: Do not take OTC anti-diarrheals or antacids without consulting your doctor or pharmacist, as they can interfere with antibiotic absorption or worsen conditions like C. difficile.

  • Steer Clear of Irritants: Refrain from consuming alcohol, high-acidic foods (like citrus juice), spicy foods, and excess caffeine, which can further irritate your sensitive digestive system.

  • Know When to See a Doctor: Seek immediate medical attention for persistent diarrhea (more than two days), severe abdominal pain, fever, or bloody stools, as these could indicate a more serious issue.

Understanding the Impact of Antibiotics on Your Gut

Antibiotics are powerful medications that fight bacterial infections, but they don't differentiate between harmful bacteria and the beneficial microorganisms in your gut microbiome. This collateral damage to your gut flora can cause an imbalance, leading to common side effects like nausea, diarrhea, cramping, and bloating. The gut microbiome plays a crucial role in digestion, nutrient absorption, and immune function, so its disruption can lead to noticeable and unpleasant gastrointestinal symptoms.

Dietary and Lifestyle Strategies for an Upset Stomach

Managing your diet is one of the most effective ways to soothe an upset stomach while on antibiotics. Certain foods can help settle your digestion, while others can make matters worse.

Bland Foods and the BRAT Diet

When your stomach is feeling sensitive, focusing on bland, easily digestible foods can make a big difference. The classic BRAT diet is often recommended for soothing diarrhea and nausea.

  • Bananas: Easy to digest and rich in potassium, which is often depleted during diarrhea.
  • Rice: White rice is easy to digest and helps bind loose stools.
  • Applesauce: A simple, non-acidic way to get some nutrients.
  • Toast: Simple, unbuttered white toast can be a good option.

Other bland options include plain crackers, potatoes, and broth-based soups. Eating smaller, more frequent meals can also help prevent your stomach from feeling overloaded.

Stay Hydrated

Diarrhea and vomiting can lead to dehydration, which can be dangerous if not managed. It's crucial to replenish lost fluids and electrolytes.

  • Water: The most important fluid for hydration. Sip it regularly throughout the day.
  • Broth: Replenishes sodium and other electrolytes.
  • Oral Rehydration Solutions: Over-the-counter products like Pedialyte can be particularly helpful for replacing lost electrolytes, especially for infants and children.
  • Herbal Teas: Ginger and chamomile tea are known for their soothing effects on the stomach.

The Role of Probiotics in Gut Recovery

Probiotics are live microorganisms that help restore the balance of your gut flora. They are a powerful tool for managing antibiotic side effects.

Probiotic Supplements

Taking a probiotic supplement is one of the most effective ways to counter the effects of antibiotics on your gut. However, proper timing is key to ensure the antibiotic doesn't kill the probiotic bacteria. Most healthcare professionals recommend taking the probiotic at least 2-3 hours before or after your antibiotic dose.

Some of the most well-researched and recommended strains for antibiotic-associated diarrhea include:

  • Lactobacillus rhamnosus GG (LGG)
  • Saccharomyces boulardii (a beneficial yeast that isn't killed by antibiotics)
  • Specific Bifidobacterium strains

Probiotic-Rich Foods

While supplements are concentrated, probiotic foods can also contribute to gut health. When consuming these, always be mindful of potential dairy interactions with your specific antibiotic.

  • Yogurt with live cultures: A common choice, but check the label to ensure it contains live and active cultures. Space dairy consumption from certain antibiotics like tetracyclines.
  • Kefir: A fermented milk drink with a variety of beneficial bacteria.
  • Fermented Vegetables: Sauerkraut and kimchi can be excellent sources of probiotics.
  • Other options: Miso, tempeh, and kombucha are also fermented foods that contain probiotics.

Over-the-Counter (OTC) Medications

Using OTC medications for an upset stomach while on antibiotics requires caution due to potential drug interactions. Always consult your doctor or pharmacist before taking anything new.

Antacids and Bismuth Subsalicylate

Some antacids contain minerals like calcium, magnesium, or aluminum that can bind to certain antibiotics and prevent proper absorption. Bismuth subsalicylate (e.g., Pepto-Bismol) can also interact with certain antibiotics, particularly tetracyclines. If you must take these, space them several hours apart from your antibiotic dose and follow a doctor's advice.

Anti-diarrheal Medications

Antidiarrheal drugs like loperamide (Imodium) are often not recommended for antibiotic-associated diarrhea without a doctor's approval. They can interfere with your body's ability to expel the harmful bacteria or toxins causing the issue.

What to Avoid While on Antibiotics

Just as important as what you should take is what you should avoid to minimize stomach upset.

  • Alcohol: Consuming alcohol with antibiotics can cause severe side effects, including nausea and vomiting.
  • High-Acidic Foods: Citrus fruits, juices, tomatoes, and sodas can irritate a sensitive stomach.
  • Spicy and Fried Foods: These can further irritate the digestive tract.
  • Caffeine: Some antibiotics can amplify the effects of caffeine, causing jitters and sleeplessness.
  • High-Fiber Foods (during active diarrhea): While fiber is generally healthy, temporarily avoiding high-fiber foods like bran and beans during acute diarrhea can help, as they can sometimes worsen symptoms.

Comparison of Remedies for Antibiotic-Induced Upset Stomach
