Elderly Prescribing in Dentistry

Topic: Safe dental prescribing for older adults

German terms: ältere Patienten, Polypharmazie, Nierenfunktion, Leberfunktion, Sturzrisiko, Delirrisiko, Wechselwirkungen

Dental role: Choose analgesics, antibiotics, local anesthetics, and sedatives safely in patients with polypharmacy, frailty, renal impairment, anticoagulants, cognitive impairment, or high adverse-effect risk.

Core principle: Older adults do not simply need “adult doses”. Prescribing must be individualized according to function, comorbidities, organ function, current medicines, and ability to follow instructions.

This article is for dental education only. Older adults have higher risk of adverse drug reactions because of polypharmacy, altered pharmacokinetics, reduced renal clearance, liver disease, dehydration, frailty, cognitive impairment, and falls. Always review current medicines, allergies, renal and liver status, anticoagulant or antiplatelet use, and the patient’s ability to understand and take the medicine safely.

Prescribing for older adults in dentistry is mainly a safety exercise. The diagnosis may be simple, but the patient may have atrial fibrillation, chronic kidney disease, heart failure, diabetes, liver disease, dementia, anticoagulants, bisphosphonates, xerostomia-inducing drugs, and several medicines from different doctors.

The safest dental prescriber first asks: What is the diagnosis? Is a medicine truly needed? Which current medicines may interact? Is renal or liver function reduced? Can the patient understand the instructions? Is there a caregiver who should receive written advice?

The key clinical principle is: start with diagnosis and medication review, then prescribe the lowest-risk effective option for the shortest necessary duration.

• Safest mindset: avoid automatic adult-dose prescribing and review patient-specific risks.
• Main risk: drug interactions and adverse effects from polypharmacy.
• Analgesic principle: paracetamol/acetaminophen is often first-line, but liver disease, frailty, low body weight, alcohol use, and duplicate products must be checked.
• NSAID principle: use with caution or avoid in chronic kidney disease, GI bleeding risk, heart failure, uncontrolled hypertension, and anticoagulant or antiplatelet therapy.
• Sedation principle: benzodiazepines increase fall, delirium, respiratory depression, and cognitive risk in older adults.

1. Confirm the dental diagnosis and decide whether medicine is truly needed.
2. Review all current medicines, including OTC analgesics, herbal products, anticoagulants, antiplatelets, bisphosphonates, denosumab, steroids, and immunosuppressants.
3. Check allergy history and previous adverse drug reactions.
4. Ask about kidney disease, liver disease, heart failure, hypertension, diabetes, gastric ulcer, asthma, falls, confusion, and dementia.
5. Check renal function when prescribing renally cleared medicines or when NSAIDs are being considered.
6. Avoid unnecessary antibiotics and treat the dental source whenever possible.
7. Use the shortest effective duration and reassess if symptoms do not improve.
8. Give large-print written instructions when possible.
9. Involve a caregiver when the patient has memory, vision, hearing, or manual-dexterity problems.
10. Document indication, dose, duration, risks checked, advice given, and follow-up plan.

• Anticoagulants / antiplatelets: bleeding risk and NSAID interaction risk.
• ACE inhibitors, ARBs, diuretics: NSAIDs can worsen kidney function, especially with dehydration.
• SSRIs, steroids, anticoagulants: increased GI bleeding risk when combined with NSAIDs.
• Warfarin: some antibiotics and analgesics can change bleeding risk or INR control.
• Bisphosphonates / denosumab: assess MRONJ risk before extractions and invasive surgery.
• Anticholinergic medicines: xerostomia, caries risk, candidiasis, and difficulty wearing dentures.
• Benzodiazepines and sedatives: falls, confusion, oversedation, and respiratory depression risk.

• Paracetamol / acetaminophen: often the first-line analgesic for dental pain in older adults when used correctly. Check total daily dose, liver disease, alcohol use, low body weight, frailty, and duplicate products.
• Ibuprofen and other NSAIDs: consider only after checking kidney function, GI bleeding risk, heart failure, blood pressure, anticoagulants, antiplatelets, and ulcer history.
• Opioids: avoid routine use; they can cause sedation, constipation, falls, confusion, nausea, and respiratory depression.
• Tramadol: generally a poor routine dental choice in older adults because of dizziness, falls, confusion, hyponatremia, seizures, and interaction risks.
• Important: analgesics support care, but irreversible pulpitis, abscess, fractured tooth, or spreading infection needs source control.

• Chronic kidney disease or uncertain renal function
• Heart failure, ischemic heart disease, vascular disease, or uncontrolled hypertension
• History of gastric ulcer, GI bleeding, or anemia
• Anticoagulant or antiplatelet therapy
• Steroid therapy, SSRI therapy, or high bleeding risk
• Dehydration, vomiting, poor oral intake, or acute illness
• ACE inhibitor / ARB plus diuretic use, where NSAIDs can increase kidney injury risk
• If an NSAID is unavoidable: use the lowest effective dose for the shortest time and consider medical advice or gastroprotection when appropriate.

• Do not prescribe antibiotics for uncomplicated pulpitis or pain without spreading infection.
• Prioritize drainage, endodontic treatment, extraction, or periodontal treatment when source control is needed.
• Check renal function before medicines requiring renal adjustment.
• Check warfarin and other interacting medicines before prescribing antibiotics.
• Older adults are more vulnerable to diarrhea, dehydration, drug interactions, and Clostridioides difficile infection.
• Clindamycin deserves particular caution because of C. difficile risk and should not be used casually.
• Use the narrowest appropriate antibiotic for the shortest recommended duration when a true indication exists.
• Give clear red flags: spreading swelling, fever, malaise, dysphagia, trismus, dehydration, or worsening symptoms.

• Calculate total local anesthetic dose, especially in low-body-weight or frail patients.
• Use aspiration and avoid intravascular injection.
• Use vasoconstrictor cautiously in unstable cardiovascular disease, severe uncontrolled hypertension, recent cardiac events, or significant arrhythmia history.
• Monitor anxiety, pain, and endogenous adrenaline release; inadequate anesthesia can be more stressful than careful vasoconstrictor use.
• Watch for post-anesthesia lip or cheek biting in patients with cognitive impairment.
• Document anesthetic type, concentration, vasoconstrictor, number of cartridges, and any adverse reaction.

• Older adults are more sensitive to benzodiazepines and sedatives.
• Diazepam has long action and active metabolites; it may increase prolonged sedation and falls.
• Midazolam requires careful titration, monitoring, escort, fasting and discharge rules, and appropriate training.
• Sedation risk is higher with sleep apnea, COPD, frailty, cognitive impairment, opioids, alcohol, and other sedatives.
• Postoperative instructions must include no driving, machinery, alcohol, or decision-making for the advised period.
• Consider non-pharmacologic anxiety control, shorter appointments, local anesthesia optimization, or specialist referral when risk is high.

• Xerostomia: caused or worsened by many medicines; increases caries, candidiasis, denture soreness, and swallowing difficulty.
• Gingival overgrowth: associated with some calcium-channel blockers, ciclosporin, and phenytoin.
• MRONJ risk: ask about bisphosphonates, denosumab, antiangiogenic medicines, steroids, chemotherapy, and cancer therapy.
• Bleeding risk: anticoagulants and antiplatelets usually should not be stopped casually; use local hemostasis and follow guidance.
• Immunosuppression: infection may progress faster and symptoms may be atypical; coordinate care when needed.

• Use simple instructions: medicine name, reason, dose, time, duration, maximum dose, and stop signs.
• Write instructions in large clear text when possible.
• Ask the patient or caregiver to repeat the plan back.
• Check whether the patient can open bottles, read labels, swallow tablets, and remember timing.
• Use blister packs, caregiver support, or pharmacy advice when adherence is difficult.
• Warn against using old antibiotics, shared painkillers, or duplicate paracetamol products.

In older adults, the safest prescription is often the one with a clear indication, the fewest interactions, the shortest duration, and the clearest written instructions.

• Rapidly spreading facial, submandibular, sublingual, or neck swelling
• Fever, malaise, dehydration, confusion, or systemic deterioration
• Trismus, dysphagia, drooling, voice change, or breathing difficulty
• Bleeding that does not stop with local measures
• Severe medication reaction: rash, swelling, wheezing, collapse, severe diarrhea, or persistent vomiting
• Suspected C. difficile diarrhea after antibiotic use
• Acute kidney injury risk: poor intake, dehydration, NSAID use, or worsening weakness
• New confusion, falls, oversedation, or respiratory depression after sedative or opioid use
• Dental pain with uncontrolled diabetes, immunosuppression, cancer therapy, or frailty

• Paracetamol / Acetaminophen
• Ibuprofen and NSAID Safety
• Antibiotic Stewardship
• Warfarin and Dental Treatment
• DOACs and Dental Treatment
• Bisphosphonates and MRONJ Risk
• Drug-Induced Xerostomia
• Drug-Induced Gingival Overgrowth
• Sedation Safety
• Renal and Liver Disease Prescribing

Elderly prescribing in dentistry requires careful diagnosis, medication review, and risk assessment. Older adults often have polypharmacy, reduced renal or hepatic reserve, anticoagulant or antiplatelet therapy, xerostomia-inducing drugs, frailty, falls risk, cognitive impairment, and a higher chance of adverse drug reactions. Paracetamol/acetaminophen is often a first-line analgesic when total dose and liver risk are checked. NSAIDs require caution because of kidney injury, GI bleeding, cardiovascular risk, hypertension, heart failure, and interactions with anticoagulants or antiplatelets. Antibiotics should be reserved for true indications and combined with dental source control. Benzodiazepines, opioids, and tramadol should be avoided or used with extreme caution because of falls, confusion, oversedation, and respiratory risks. Safe prescribing includes clear written instructions, caregiver support when needed, short duration, follow-up, and urgent referral for spreading infection, severe adverse reaction, uncontrolled bleeding, or systemic deterioration.
