Identify the Cause of Diarrhea Before Choosing a Treatment
Diarrhea can have different causes—viral, bacterial, parasitic, or food-related—each requiring a different treatment approach.
Before taking medication, it’s important to understand what’s causing your diarrhea. Treatment varies depending on the cause:
- Viral infections (e.g., Rotavirus, Norovirus): ORS and supportive care; antibiotics are not needed.
- Bacterial infections (e.g., E. coli, Salmonella, Cholera): Mild cases require ORS and probiotics, while severe cases may need antibiotics like ciprofloxacin or azithromycin.
- Parasitic infections (e.g., Amoebiasis, Giardiasis): Requires antiparasitic medications like metronidazole or tinidazole.
- Food intolerance or IBS-related diarrhea: Avoid triggers, adjust your diet, and consider probiotics for gut health.
Attention: Know When to Seek Medical Attention for Severe Cases
Medical help is necessary if diarrhea lasts over 48 hours, dehydration symptoms appear, or blood is present in the stool.
Diarrhea is common, but not all cases should be self-treated. While mild cases can be managed at home, there are situations where consulting a doctor is necessary.
Seek medical attention if you experience:
- Severe dehydration symptoms like dry mouth, sunken eyes, dizziness, or reduced urination.
- High fever (≥38.5°C).
- Bloody, black, or mucoid stools.
- Diarrhea lasting more than 48 hours.
- Severe abdominal pain or signs of shock such as confusion, rapid breathing, or cold skin.
Additionally, pregnant women, elderly individuals, children, and immunocompromised persons should be extra cautious and consult a healthcare professional before taking any medication.
How to Choose a Diarrhea Medicine - Buying Guide
Choosing the right diarrhea medicine can make a big difference in recovery. This guide will walk you through safe and effective options to help you feel better faster.
Avoid Counterfeits: Get FDA-Approved Medicine From Trusted Retailers
Consumers should verify FDA approval and purchase from licensed pharmacies to ensure they are getting safe, regulated products.
Ensuring that a diarrhea medicine is FDA-approved is the first step in choosing a safe and effective treatment. In the Philippines, the Food and Drug Administration (FDA) regulates medications to ensure they meet safety and quality standards. To verify if a medicine is approved, consumers can check the Philippine FDA website for registered medications or look for DOH and FDA certification marks on the packaging.
Purchasing from licensed pharmacies such as Mercury Drug and Watsons or from trusted online platforms like LazMall and Shopee Mall also reduces the risk of counterfeit or unregulated products. Unverified medicines bought from unknown sellers, especially online, may contain harmful or ineffective ingredients, making them unsafe for consumption.
Oral Rehydration Solution (ORS-75): First Line of Treatment and Essential for Hydration and Recovery
ORS should always be the first treatment before considering anti-diarrheal medication. It prevents dehydration, which is the most critical complication of diarrhea.
ORS (ORS-75 in particular) is the gold standard for preventing dehydration caused by diarrhea. Unlike sports drinks, which often contain excessive sugar that can worsen symptoms, ORS follows a medically approved glucose-sodium ratio that helps the body absorb fluids efficiently.
ORS is particularly important in hot climates like the Philippines, where fluid loss from diarrhea can worsen quickly. It is recommended for mild to moderate diarrhea to replace lost electrolytes and prevent complications. For severe diarrhea, ORS should be taken immediately while seeking medical help.
If ORS is unavailable, coconut water can be a temporary alternative, but it lacks the essential sodium levels needed for proper rehydration.
Choose Based on Your Specific Needs
Different diarrhea treatments work best for specific cases. Whether you need fast relief, a gentle option for pregnancy or elderly care, or a long-term gut health solution, selecting the right medicine ensures safe and effective management.
For Fast Relief: Use Loperamide or Racecadotril as Needed
Loperamide provides fast relief for non-infectious diarrhea, while racecadotril is safer for infectious diarrhea as it doesn’t slow gut movement.
For those looking for quick symptom relief, two common OTC medicines are available:
Loperamide (ex. Imodium, Diatabs) – Works by slowing down gut movement, reducing the frequency of bowel movements. It is best for non-infectious diarrhea (e.g., food-related cases) but should not be used for bacterial or bloody diarrhea.
- Dosage: 4 mg initially, then 2 mg after each loose stool (Max: 16 mg per day).
Racecadotril (ex. Hidrasec) – Works by reducing excess water loss in stools without slowing digestion. This makes it safer for infectious diarrhea.
- Dosage: 100 mg every 8 hours before meals (Stop once diarrhea resolves, max duration: 7 days).
If unsure, consult a doctor to determine the best option for your symptoms.
For Pregnant and Breastfeeding Women: Stick to Safe and Mild Options
ORS and probiotics are the safest options. Loperamide should be avoided unless prescribed by a healthcare professional.
Pregnant and breastfeeding mothers need to be extra cautious with medications. The safest options include:
- ORS: The first-line treatment to prevent dehydration.
- Probiotics: Helps restore healthy gut bacteria balance. Lactobacillus rhamnosus GG and Saccharomyces boulardii are particularly effective strains for diarrhea relief.
- Fiber-rich foods: Natural alternatives that help regulate digestion.
Avoid loperamide, strong anti-diarrheal drugs, and herbal supplements with unknown safety profiles. If symptoms persist, consult an OB-GYN for pregnancy-safe treatment options.
While yogurt with active cultures can provide some probiotic benefits, supplements offer a higher concentration of beneficial bacteria, making them a more effective choice for managing diarrhea.
For the Elderly: Choose Gentle and Easy-to-Take Options
Seniors are at higher risk of dehydration, so ORS should be prioritized. Liquid probiotics and chewable tablets are good alternatives for those with difficulty swallowing pills.
Older adults have weaker digestive systems and are more vulnerable to dehydration. The best options include:
- ORS: The first step in preventing severe dehydration.
- Racecadotril: A gentle alternative to loperamide, as it doesn’t slow digestion.
- Probiotics: Helps improve gut health and prevent recurring diarrhea. Lactobacillus rhamnosus GG and Saccharomyces boulardii are recommended for long-term digestive support.
If swallowing is difficult, go for liquid probiotics or chewable tablets instead of large pills.

Frequently Asked Questions
Below, Dr. Eron Tan answers some of the most asked questions we found on the web.
Can Overusing Anti-Diarrheal Medicines Cause Problems?
While anti-diarrheal medicines provide relief, they should be used correctly. Loperamide, in particular, should not be taken in cases of bacterial infections like C. difficile colitis, as it can trap bacteria and toxins in the gut, making the infection worse. If symptoms persist or worsen, it's best to consult a doctor.
Can Diarrhea Medicine Be Taken on an Empty Stomach?
Most diarrhea medications can be taken with or without food, but some may work more effectively when taken at a specific time. Here’s what you need to know:
- Loperamide – Can be taken with or without food.
- Racecadotril – Best taken before meals for better absorption.
- ORS & Probiotics – Can be taken anytime.
Can Diarrhea Medicine Be Taken Alongside Antibiotics or Maintenance Drugs?
Some diarrhea medications can be safely taken with other medications, but certain combinations should be avoided.
- Loperamide – Safe with most maintenance drugs but should not be used if taking antibiotics for bacterial diarrhea.
- Racecadotril – Generally safe with other medications.
- Probiotics – Safe and beneficial in reducing antibiotic-associated diarrhea.
Remember to always consult with a healthcare professional for the best advice and recommendations for your condition.
What Are the Common Side Effects of Diarrhea Medicine?
Most over-the-counter diarrhea medicines are well-tolerated when taken as directed, but some may cause mild to moderate side effects. Loperamide can lead to constipation, bloating, and drowsiness, while racecadotril is generally well-tolerated but may cause nausea or a mild skin rash.
Probiotics may cause temporary bloating or gas, and ORS is safe for most people but should be taken in appropriate amounts to maintain electrolyte balance. If side effects persist or worsen, consult a doctor.
