Propranolol

Dosage Forms Available

• Propranolol is available in various oral dosage forms, including tablets, extended-release capsules, oral solutions, and injectable forms.

Age and Dose Restrictions

• Propranolol is not recommended for children under the age of 12 unless prescribed by a healthcare professional. 

Contraindications

• Propranolol should not be used by individuals with a known allergy to propranolol or other beta-blockers. It is contraindicated in patients with severe asthma, chronic obstructive pulmonary disease (COPD), uncontrolled heart failure, bradycardia (slow heart rate), and certain types of heart block.

Other Medications to Avoid

• Avoid combining propranolol with calcium channel blockers (such as verapamil and diltiazem), antiarrhythmic medications (such as amiodarone), certain antidepressants (such as fluoxetine and paroxetine), nonsteroidal anti-inflammatory drugs (NSAIDs), and diabetic medications, as they may alter the effectiveness and safety of propranolol.

Overdose and Missed Dose

• Overdose of propranolol can lead to life-threatening bradycardia, hypotension, and respiratory distress. Seek immediate medical attention if an overdose is suspected. 
• If a dose is missed, take it as soon as remembered. However, if the next dose is near, skip the missed dose and resume the regular dosing schedule. Do not double the dose to make up for the missed one.

Management of Side Effects

• Fatigue and dizziness can be managed by taking propranolol at bedtime. If experiencing nausea, take it with food. Cold hands and feet can be alleviated by wearing warm clothing. If side effects persist or worsen, consult a doctor for alternative treatment options.

Use in Driving and Operating Machinery

• Propranolol may cause dizziness and drowsiness. It is advised to avoid driving, operating heavy machinery, or performing tasks requiring alertness until the individual knows how the medication affects them.

Use in Pregnancy and Lactation

• Propranolol should be used during pregnancy only if clearly needed and prescribed by a doctor. It may cause fetal growth restriction or low blood sugar in newborns. It is excreted in breast milk, so breastfeeding mothers should consult a doctor before using propranolol.

Caution in Other Conditions

• Caution is advised in patients with diabetes, as propranolol may mask symptoms of low blood sugar. It should also be used carefully in those with liver or kidney disease, psychiatric disorders, or peripheral vascular disease.

Special Dietary and Lifestyle Recommendations

• Reduce caffeine and alcohol intake as they may counteract propranolol’s effects.
• Engage in regular physical activity to maintain heart health. Maintain a healthy, low-sodium diet to control blood pressure levels. 
• Avoid sudden discontinuation of the medication, as it can cause rebound hypertension or increased heart rate.
