๐ฟ OTC Laxatives
What Are They?
Laxatives are medications that help stimulate or facilitate bowel movements. They are used to relieve constipation, which can be caused by poor diet, lack of exercise, stress, or certain medical conditions.
Types of Laxatives:
- Bulk-forming agents (e.g., psyllium, methylcellulose): Increase stool bulk by absorbing water.
- Stool softeners (e.g., docusate sodium): Help mix water into the stool, making it easier to pass.
- Stimulant laxatives (e.g., senna, bisacodyl): Stimulate intestinal muscles to move stool.
- Osmotic laxatives (e.g., polyethylene glycol, milk of magnesia): Draw water into the colon to soften stool.
- Lubricant laxatives (e.g., mineral oil): Coat the stool for easier passage.
When to Use:
Use laxatives for occasional constipation. They should not be used long-term without medical supervision, as they can cause dependency.
Possible Side Effects:
- Bloating and gas (bulk-forming)
- Cramping (stimulant laxatives)
- Diarrhea or electrolyte imbalance (osmotic types)
- Nutrient absorption interference (long-term use)
๐ Antacids
What Are They?
Antacids are OTC medications used to neutralize stomach acid, offering relief from heartburn, acid indigestion, and upset stomach.
Common Ingredients:
- Calcium carbonate (e.g., Tums)
- Magnesium hydroxide (e.g., Milk of Magnesia)
- Aluminum hydroxide
- Sodium bicarbonate
When to Use:
Antacids are ideal for quick relief of occasional acid reflux or indigestion. They're not a long-term solution for chronic GERD or peptic ulcers.
Possible Side Effects:
- Constipation (aluminum-based)
- Diarrhea (magnesium-based)
- Belching and gas (sodium bicarbonate)
- Kidney problems (long-term excessive use)
