What Signs or Symptoms Suggest That I Should See a Doctor Instead of Self-Medicating for Stomach Pain?
If you experience any of the following signs or symptoms, it’s important to see a doctor instead of self-medicating for stomach pain:
Age ≥60 with new dyspepsia
GI bleeding (hematemesis, melena, occult blood)
Iron deficiency anemia
Unexplained weight loss or anorexia
Dysphagia (difficulty swallowing) or odynophagia (painful swallowing)
Persistent vomiting
A family history of GI cancer in a first-degree relative
These are considered alarm features that require professional medical evaluation.
How to Choose Medicines for Stomach Pain - Buying Guide
Opt for Trusted Brands and FDA-Registered Products
FDA registration ensures a medicine’s safety, quality, and authenticity for safer self-medication.
To ensure safety and effectiveness, always choose FDA-registered products. Unregistered medicines may contain incorrect dosages, harmful contaminants, or lack the proper active ingredients altogether. To check if a product is registered, visit the official FDA Philippines website.
Sticking to trusted brands also reduces the risk of unexpected side effects and drug interactions, especially when self-medicating.
Choose the Right Type of Medicine for Your Symptoms
For Acidity, Heartburn, or Acid Reflux: Look for Antacids or Acid Reducers
PPIs work best for reflux, while antacids and H2 blockers treat mild or short-term acidity.
If you feel heartburn after meals or when lying down, try antacids for quick relief or H2 blockers like famotidine. H2 blockers, or histamine-2 receptor antagonists, reduce the amount of acid your stomach produces.
For frequent or stronger symptoms, proton pump inhibitors (PPIs) like omeprazole offer longer-lasting control by blocking acid production more effectively. PPIs block acid production at the proton pump level, offering long-term acid suppression. Note, however, that long-term PPI use should be supervised due to potential risks such as B12 deficiency, bone fractures, or infection.
For Gas, Bloating, and Indigestion: Opt for Simethicone-Based or Enzyme Products
Simethicone relieves trapped gas, while enzymes help with food-related indigestion or intolerance.
Simethicone, an anti-foaming agent, is best for relieving gas trapped in the stomach or intestines. It helps coalesce gas bubbles, making them easier to eliminate.
If your bloating happens after meals or with certain foods, digestive enzymes may help by breaking down fats, carbs, or proteins. Check the label to use them properly and avoid combining too many ingredients at once, which may cause side effects or reduce effectiveness.
For Cramping, Diarrhea, or Constipation: Go for Antispasmodics, Anti-Diarrheals, or Laxatives
Antispasmodics ease cramps or spasms, anti-diarrheals reduce bowel movement, and laxatives treat constipation.
Antispasmodics like mebeverine help relieve stomach cramps caused by IBS (irritable bowel syndrome) or GI (gastrointestinal) disorders. For diarrhea, loperamide slows gut movement, while laxatives stimulate or soften stools for constipation.
These medicines target different symptoms, so choose based on what you're experiencing. Always follow dosage instructions carefully, and avoid combining multiple remedies unless advised by a healthcare professional, as this may lead to unwanted effects.
For Mild or General Stomach Discomfort: Pick Probiotics and Herbal or Natural Remedies
Probiotics are useful for IBS or mild bloating, not for sudden or severe stomach pain.
Probiotics can support gut health after antibiotic use or help manage mild cases of IBS, but they’re not suitable for infections or sudden, severe pain. They are also not a replacement for antibiotics or other definitive treatments in acute infectious gastroenteritis.
Some herbal remedies may also offer relief, but it's important to avoid unregistered products—especially when treating children. To ensure safety and proper dosing, only use herbal medicines recommended by your doctor or pediatrician.
Consider Dosage Guidelines Based on Age
Age affects safety and dosing—children and the elderly need age-appropriate, lower-dose, or easy-to-swallow forms.
For Children: Follow Weight- or Age-Based Dosing
Children are vulnerable to side effects, so careful selection is key.
For children, always use pediatric formulations with age- or weight-based dosing. Avoid giving adult-strength products. Specifically, steer clear of bismuth subsalicylate, strong laxatives, and antacids with high aluminum or magnesium content in children under 2.
Dosage guidelines for children:
Omeprazole (PPI)
5–10 kg: 5 mg once daily
10–20 kg: 10 mg once daily
20 kg: 20 mg once daily
Famotidine (H2 blocker)
1 mg/kg/day, divided into two doses (max: 40 mg/day total in divided doses)
Mebeverine (antispasmodic)
4–8 years: 50 mg three times daily
8–10 years: 100 mg three times daily
For Adults: Follow Recommended Guidelines and Adjust Based on Specific Health Conditions
Adults generally follow standard dosages, but special care is needed for elderly individuals, especially with certain medications.
Dosage guidelines for adults:
Omeprazole: 20–40 mg once daily for 4–8 weeks
Famotidine (Adults with GERD): 20 mg twice daily for 6 weeks. If you have renal impairment (creatinine clearance <50 mL/min), the dose should be reduced.
Mebeverine: 135 mg three times daily before meals, or 100 mg four times daily. Should be taken 20 minutes before meals; do not chew tablets.
Aluminum + Magnesium Hydroxide: 10–20 mL up to four times a day (max: 80 mL/day). Avoid in severe renal impairment.
For the elderly, start with lower doses to prevent side effects like dehydration and constipation, and monitor for interactions with other medications.
Check the Form: Tablets, Capsules, Liquids, or Chewables
Liquids and chewables act faster, while capsules and coated tablets are more stable. The right form also depends on swallowing ability.
The form of the medicine can affect both how quickly it works and how easy it is to take. Liquids and chewables are typically absorbed faster, making them ideal for quick relief. In contrast, enteric-coated tablets or capsules are designed to dissolve more slowly, which can provide longer-lasting effects. These delayed-release formulations also help reduce stomach irritation, though they may not act as quickly as liquids or chewables.
For children, the elderly, or those with swallowing difficulties, suspensions or dissolvable tablets are the safest and most convenient options. Always choose the form that best suits the patient’s age, ability, and need for speed of relief.
