Medication plays a huge role in modern healthcare—but with so many prescriptions being written, especially for older adults, there’s growing concern about polypharmacy, drug interactions, and overuse.
This post takes a closer look at the 10 most commonly prescribed medications in 2025—why they’re used, the risks of overuse, and how to reduce dependence on medication when possible.
Many patients today take multiple medications, often prescribed by different doctors. If you’re seeing specialists but don’t have a primary care provider coordinating your care, it’s easy for prescriptions to pile up—sometimes duplicating or interacting in dangerous ways. The system doesn’t always flag these issues, and unfortunately, the burden often falls on the patient or family to sort it out.
Let’s break down these top medications, understand their intended use, and talk about how to use them wisely—especially in older adults, who are most at risk for complications.
Use: Lowers cholesterol and reduces heart disease risk
Common Side Effects:
• Muscle pain or weakness
• Liver enzyme changes
• Digestive issues (constipation, gas)
In Older Adults: Higher risk of muscle breakdown (rhabdomyolysis), memory complaints, and interactions with other meds
Overuse Concern: Often prescribed before trying diet and exercise
Tip: Consider a heart-healthy diet (like the Mediterranean diet), regular walking, and weight management before starting statins.
Use: High blood pressure and chest pain (angina)
Common Side Effects:
• Swelling in legs (edema)
• Dizziness
• Fatigue
In Older Adults: Increased fall risk, leg swelling from lower activity
Overuse Concern: Sometimes used for mild hypertension before lifestyle changes are attempted
Tip: Reduce sodium, increase activity, and manage stress to lower blood pressure naturally.
Use: Hypothyroidism (low thyroid hormone)
Common Side Effects (especially with overtreatment):
• Anxiety, palpitations
• Weight changes
• Sleep problems
In Older Adults: Risk of irregular heartbeat (atrial fibrillation), bone loss, and confusion
Overuse Concern: Prescribed for “low-normal” thyroid levels without symptoms
Tip: Recheck thyroid labs regularly and treat based on both labs and symptoms—not just one or the other.
Use: Lowers blood pressure, treats heart failure
Common Side Effects:
• Dry cough
• Dizziness
• Kidney changes
In Older Adults: Higher risk of dehydration, dizziness, kidney injury (especially with diuretics)
Overuse Concern: Sometimes started before trying non-drug interventions
Tip: Weight loss, potassium-rich foods, and the DASH diet can delay or reduce the need for medication.
Use: Nerve pain, seizures
Common Side Effects:
• Drowsiness
• Dizziness
• Swelling
In Older Adults: High risk of confusion, sedation, falls, and long-term dependence
Overuse Concern: Commonly prescribed off-label for anxiety or insomnia—without strong evidence
Tip: Consider physical therapy, cognitive behavioral therapy (CBT), and safe sleep routines before long-term use.
Use: Acid reflux (GERD), ulcers
Common Side Effects (especially long-term):
• B12 and magnesium deficiency
• Bone loss/fractures
In Older Adults: Increased risk of hip fractures, kidney damage, and gut infections like C. diff
Overuse Concern: Often continued indefinitely for minor symptoms
Tip: Adjust your diet, avoid trigger foods, and eat smaller meals earlier in the day to reduce reflux naturally.
Use: Type 2 diabetes
Common Side Effects:
• Diarrhea, bloating
• Low vitamin B12 levels
In Older Adults: Risk of lactic acidosis in kidney impairment; B12 deficiency can lead to nerve or memory issues
Overuse Concern: Given for prediabetes without a strong push for lifestyle change
Tip: A structured lifestyle program can reverse prediabetes in many people. Walking 30 minutes a day can make a huge difference.
Use: Depression, anxiety
Common Side Effects:
• Nausea
• Sexual side effects
• Trouble sleeping or fatigue
In Older Adults: Can cause low sodium, increased fall risk, and interact with blood thinners or NSAIDs
Overuse Concern: Prescribed for situational sadness or stress without trying therapy or support
Tip: Talk therapy, social connection, mindfulness, and movement can help with mild to moderate symptoms.
Use: Quick relief inhaler for asthma and COPD
Common Side Effects:
• Tremors
• Fast heartbeat
• Jitteriness
In Older Adults: May worsen heart conditions or cause anxiety and falls
Overuse Concern: Used without pairing it with long-term controller medications
Tip: Make sure you have a full asthma or COPD action plan with long-term management from a specialist.
Use: Type 2 diabetes, weight loss
Common Side Effects:
• Nausea, vomiting
• Constipation
• Rare pancreatitis
In Older Adults: Risk of dehydration and malnutrition, especially with unintended weight loss
Overuse Concern: Widespread off-label use for weight loss has caused shortages for diabetic patients
Tip: Work with a dietitian or health coach on sustainable habits—weight loss is not just about the scale.
Many of these medications are lifesaving—but they can also cause serious harm when overprescribed, misused, or taken without proper monitoring.
• Ask for a yearly medication review with your primary care provider
• Talk about “deprescribing”—especially if you’re on 5+ meds
• Prioritize lifestyle changes: movement, nutrition, sleep, and support
• Always ask: “Is there a non-drug way to manage this?”
• Get a second opinion if something doesn’t feel right
