- Ergot alkaloids (increased peripheral vasoconstriction)
Moderate Interactions
- NSAIDs (may reduce antihypertensive effect)
- CYP2D6 inhibitors (e.g., fluoxetine, paroxetine, quinidine - increased propranolol levels)
- CYP1A2 inhibitors (e.g., fluvoxamine - increased propranolol levels)
- CYP2C19 inhibitors (e.g., omeprazole - increased propranolol levels)
- Phenytoin, phenobarbital, rifampin (CYP inducers - decreased propranolol levels)
- Alcohol (increased propranolol levels)
- Cimetidine (increased propranolol levels)
- Lidocaine (increased lidocaine levels)

Minor Interactions
- Antacids (may decrease absorption of propranolol)
Monitoring
Baseline Monitoring
Rationale: To establish baseline and guide titration for antihypertensive effect.
Timing: Prior to initiation
Rationale: To establish baseline and monitor for bradycardia.
Timing: Prior to initiation
Rationale: To assess cardiac rhythm and conduction, especially in patients with pre-existing cardiac conditions.
Timing: Prior to initiation (if clinically indicated)
Rationale: To assess kidney health, though dose adjustment is rarely needed, it's important for overall patient assessment.
Timing: Prior to initiation
Rationale: To assess hepatic function, as propranolol is extensively metabolized by the liver.
Timing: Prior to initiation
Routine Monitoring
Frequency: Regularly, especially during dose titration and periodically thereafter (e.g., weekly during titration, then monthly/quarterly)
Target: Individualized based on indication (e.g., <130/80 mmHg for hypertension)
Action Threshold: Hypotension (e.g., SBP <90 mmHg or symptomatic), or inadequate control
Frequency: Regularly, especially during dose titration and periodically thereafter (e.g., weekly during titration, then monthly/quarterly)
Target: Typically >50-60 bpm (unless specific therapeutic bradycardia is desired)
Action Threshold: Bradycardia (<50 bpm or symptomatic), or inadequate control
Frequency: At each visit and patient education for self-monitoring
Target: Absence of symptoms
Action Threshold: Development of new or worsening symptoms (e.g., dizziness, fatigue, shortness of breath, cold extremities)
Frequency: Regularly, as per diabetes management guidelines
Target: Individualized
Action Threshold: Hypoglycemia (propranolol can mask symptoms)
Symptom Monitoring
- Bradycardia (slow heart rate)
- Hypotension (dizziness, lightheadedness, fainting)
- Fatigue, lethargy
- Cold hands and feet (peripheral vasoconstriction)
- Shortness of breath, wheezing (bronchospasm, especially in asthmatics)
- Insomnia, nightmares
- Depression
- Nausea, vomiting, diarrhea, constipation
- Masked symptoms of hypoglycemia (in diabetics)
Special Patient Groups
Pregnancy
Propranolol is Pregnancy Category C. Studies in animals have shown adverse effects on the fetus, but there are no adequate and well-controlled studies in pregnant women. It should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Neonates exposed to beta-blockers in utero may be at risk for bradycardia, hypoglycemia, and respiratory depression.
Trimester-Specific Risks:
Lactation
Propranolol is excreted into breast milk. The American Academy of Pediatrics considers it 'compatible with breastfeeding'. However, monitor breastfed infants for signs of beta-blockade (e.g., bradycardia, lethargy, hypoglycemia). Use with caution, especially in premature or unstable infants.
Pediatric Use
Dosing must be carefully individualized based on weight, age, and indication. Neonates and infants are particularly sensitive to the effects of beta-blockade. Close monitoring for bradycardia, hypotension, and hypoglycemia is essential. Specific formulations (e.g., oral solution for infantile hemangioma) are available.
Geriatric Use
Elderly patients may be more sensitive to the effects of propranolol, particularly bradycardia and hypotension. Lower initial doses and slower titration are recommended. Renal and hepatic function should be assessed, as age-related decline in these functions can affect drug clearance.
Clinical Information
Clinical Pearls
- Always warn patients about the risk of abrupt discontinuation, especially if they have underlying ischemic heart disease.
- Propranolol is highly lipophilic, leading to significant CNS penetration, which can cause side effects like nightmares, insomnia, and depression.
- It is a non-selective beta-blocker, so it should be used with extreme caution or avoided in patients with asthma, COPD, or other bronchospastic diseases due to the risk of bronchospasm.
- Can mask symptoms of hypoglycemia in diabetic patients, except for sweating.
- Food significantly increases the bioavailability of propranolol; advise consistent administration with respect to meals (e.g., always with food or always on an empty stomach).
- Extended-release formulations (Inderal LA) allow for once-daily dosing, improving adherence.
Alternative Therapies
- Other beta-blockers (e.g., metoprolol, atenolol, carvedilol, bisoprolol)
- Calcium channel blockers (e.g., amlodipine, nifedipine, diltiazem, verapamil)
- ACE inhibitors (e.g., lisinopril, enalapril)
- Angiotensin receptor blockers (ARBs) (e.g., losartan, valsartan)
- Diuretics (e.g., hydrochlorothiazide, furosemide)
- Alpha-blockers (e.g., prazosin, doxazosin)
- For migraine prophylaxis: Topiramate, valproic acid, CGRP inhibitors
- For essential tremor: Primidone
