Issues that require pharmacist intervention
Table of Contents
Pharmacists play a critical role in patient safety and medication optimization by intervening in various clinical and drug-related issues. Below is a structured breakdown of key issues requiring pharmacist intervention, along with examples and actions:
Drug Utilization Review (DUR)
Drug Utilization Review (DUR) is a systematic process used by pharmacists to evaluate a patient’s medication therapy to ensure safety, efficacy, and appropriateness. DUR helps identify and prevent medication-related problems such as drug interactions, incorrect dosages, and unnecessary treatments.Types of DUR
1. Prospective DUR (Before Dispensing)
- Conducted before the medication is dispensed.
- Helps prevent medication errors before they reach the patient.
Examples:
- Identifying a drug allergy before filling a prescription.
- Detecting a potential drug interaction with a patient’s current medications.
- Noticing an incorrect dose for a child’s weight.
2. Concurrent DUR (During Therapy)
- Ongoing review while the patient is actively taking the medication.
- Ensures therapy remains safe and effective over time.
Examples:
- Monitoring a diabetic patient for hypoglycemia while on insulin.
- Checking if a patient on opioids is showing signs of dependency or overuse.
3. Retrospective DUR (After Therapy)
- Conducted after the medication has been dispensed and taken by the patient.
- Used to identify patterns of inappropriate prescribing or usage.
Examples:
- Identifying patients who have been prescribed multiple benzodiazepines from different providers.
- Analyzing if a provider is overprescribing certain high-risk medications.
| Type of DUR | When It Occurs | Purpose | Examples |

Adverse Drug Events (ADEs)
An Adverse Drug Event (ADE) is any harmful or unintended reaction caused by a medication. Pharmacists play a key role in identifying, preventing, and managing ADEs to improve patient safety.
Common ADEs Requiring Pharmacist Intervention

Over-the-Counter (OTC) Recommendations
Pharmacists play a vital role in guiding patients on the safe and effective use of OTC medications. Certain situations require pharmacist intervention to prevent drug interactions, misuse, and adverse effects.
Common OTC Scenarios Requiring Pharmacist Intervention
1. Drug Interactions with Prescription Medications2. Selecting the Right OTC Product for Symptoms
3. Preventing Duplicate Therapy or Overuse
4. Recommending Alternatives for High-Risk Patients
5. Identifying Potential Misuse or Abuse
6. Advising on Proper OTC Use and Dosing
Therapeutic Substitution
Therapeutic substitution is when a pharmacist replaces a prescribed medication with a different drug in the same class that has a similar therapeutic effect but may differ in cost, availability, or formulation. Pharmacist intervention is critical to ensure patient safety, effectiveness, and adherence.

Post-Immunization Follow-Up
Administering vaccines is just the first step—pharmacists must monitor for adverse effects, ensure immunity, and provide counseling. Below are key scenarios where pharmacist intervention is critical after vaccination.
Key Areas for Pharmacist Intervention in Post-Immunization Follow-Up
1. Managing Common Side EffectsPharmacist Action:
- Reassure the patient that mild pain, redness, and swelling are normal.

- If severe, refer to an allergist or recommend an alternative travel vaccine if applicable.
- Consult the oncologist before proceeding with any vaccination.
Recommendation for Pharmacy Technicians – Counseling based on above topics
Pharmacy technicians play a critical support role in medication safety but must never provide clinical counseling or make recommendations about drug interactions, contraindications, allergies, or other pharmacist-specific interventions. Instead, technicians should recognize when a pharmacist is needed and properly redirect patient inquiries. (Very Important)
How Pharmacy Technicians Should Handle Patient Questions

Patient: “I’m allergic to penicillin. Can I take this with amoxicillin?”
Technician Response: “That’s an important question. Let me get the pharmacist to go over that with you.”
Patient: “Can I take ibuprofen with my blood thinner?”
Technician Response: “The pharmacist is the best person to help with drug interactions. Let me call them over for you.”
📌 Example:
Patient: “I’m allergic to penicillin. Can I take this with amoxicillin?”
Technician Response: “That’s an important question. Let me get the pharmacist to go over that with you.”

Technician Response: “The pharmacist is the best person to help with drug interactions. Let me call them over for you.”
If a Patient Asks About OTC Recommendations
📌 Example:
Patient: “Which cold medicine is best for me if I have high blood pressure?”
Technician Response: “That’s a great question for the pharmacist. Let me grab them for you.”
Patient: “Can I take this allergy medication with my diabetes?”
Technician Response: “I’ll have the pharmacist check that for you. Please wait just a moment.”

If a Patient Has Concerns About a Prescription
📌 Example:
Patient: “Why did my doctor change my medication?”
Technician Response: “I’m not able to discuss medication changes, but the pharmacist can explain that for you.”
Patient: “Is there a cheaper alternative to this medication?”
Technician Response: “The pharmacist can review cost-saving options with you. Let me get them for you now.”
📌 Example:
Patient: “Why did my doctor change my medication?”
Technician Response: “I’m not able to discuss medication changes, but the pharmacist can explain that for you.”
Patient: “Is there a cheaper alternative to this medication?”
Technician Response: “The pharmacist can review cost-saving options with you. Let me get them for you now.”
If a Patient Asks About a Missed Dose or How to Take Medication
📌 Example:
Patient: “I missed my dose this morning—should I take it now?”
Technician Response: “The pharmacist can advise you on missed doses. Let me bring them over.”
Patient: “Should I take this with food or on an empty stomach?”
Technician Response: “The pharmacist can explain the best way to take your medication. Give me a moment to get them.”
📌 Example:
Patient: “I missed my dose this morning—should I take it now?”
Technician Response: “The pharmacist can advise you on missed doses. Let me bring them over.”
Patient: “Should I take this with food or on an empty stomach?”
Technician Response: “The pharmacist can explain the best way to take your medication. Give me a moment to get them.”
Key Takeaways for Pharmacy Technicians
✅ Know when to redirect – Any question about drug interactions, allergies, side effects, dosage, or recommendations must go to the pharmacist.
✅ Use clear, professional language – Never guess or give personal opinions.
✅ Be proactive – If you notice a potential issue (e.g., allergy alert on a prescription), notify the pharmacist immediately.
✅ Reassure the patient – Let them know the pharmacist will help them with the best advice.
