About Inderal La
Inderal La (propranolol) is a prescription-only beta-blocker formulated as extended-release tablets. It belongs to the class of non-selective β-adrenergic antagonists and is approved in Singapore for managing hypertension, angina, certain cardiac arrhythmias, and for the prevention of migraine attacks. By dampening sympathetic nervous system activity, it also helps reduce the physical sensations that accompany anxiety and stress-related conditions.
What is Generic Inderal La (propranolol)?
Generic Inderal La (propranolol) is the extended-release (LA) formulation of propranolol hydrochloride, a non-selective beta-adrenergic blocker. It received approval from the Health Sciences Authority (HSA) in Singapore and is listed on the national drug formulary for cardiovascular and neurological indications. The tablet releases the active ingredient steadily over 24 hours, allowing once-daily dosing, which improves adherence compared with immediate-release versions.
How Inderal La Works
Inderal La blocks β₁-adrenergic receptors in the heart and β₂-receptors in peripheral vessels and bronchial smooth muscle:
- Cardiac Effects - Inhibition of β₁ receptors reduces heart rate, myocardial contractility, and renin release, lowering cardiac output and blood pressure.
- Vascular Effects - β₂ blockade prevents vasodilation in skeletal muscle, contributing to a modest reduction in peripheral resistance.
- Migraine Prophylaxis - By stabilising vascular tone and attenuating central sympathetic outflow, propranolol diminishes the cortical spreading depression that triggers migraine aura.
- Anxiety Modulation - The drug blunts the surge of epinephrine that fuels the “fight-or-flight” response, curbing tremor, palpitations, and the sensation of a racing heart during stressful situations.
Pharmacokinetically, the LA tablet is absorbed slowly, reaching peak plasma concentrations in 6-8 hours. The half-life ranges from 3 to 6 hours, but the extended-release matrix maintains therapeutic levels for a full day. Metabolism occurs primarily via CYP2D6 in the liver, with renal excretion of metabolites.
Why Inderal La is Used for Heart Health, Migraine, and Anxiety Conditions
- Hypertension and Angina - By decreasing heart rate and contractile force, the drug reduces myocardial oxygen demand, alleviating chest pain and lowering systemic pressure.
- Cardiac Arrhythmias - β-blockade slows atrioventricular conduction, making it effective for supraventricular tachycardia and ventricular ectopy.
- Migraine Prevention - Clinical trials show a 30-50 % reduction in migraine frequency with daily propranolol, positioning it as a first-line prophylactic agent in most guidelines.
- Performance-Related Anxiety - The attenuation of physiological arousal helps individuals facing public speaking or high-stakes performances experience fewer somatic anxiety symptoms.
- Guideline Position - International and Singaporean cardiovascular societies list propranolol as a preferred β-blocker for secondary prevention after myocardial infarction and for chronic stable angina.
Off-Label and Investigational Uses of Inderal La
Evidence from randomized controlled trials suggests propranolol may lessen the intensity of post-traumatic stress disorder (PTSD) flashbacks and reduce tremor in essential tremor patients resistant to first-line therapies. These applications are not approved by the HSA in Singapore and should only be pursued under specialist supervision. Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Inderal La Right for You?
Inderal La is suitable for adults who require stable cardiovascular control, migraine prophylaxis, or anxiety-related symptom relief. It is especially beneficial for patients who prefer once-daily dosing. Contraindications include severe asthma, uncontrolled heart failure, and pronounced bradycardia. Caution is advised in the elderly, in individuals with hepatic impairment (dose adjustment may be required), and during pregnancy-where the drug is classified as Category C and should be used only if the potential benefit justifies the risk.
Taking Inderal La Effectively
- Timing - Take the tablet with food in the morning to minimise gastrointestinal upset and to align peak concentrations with daily activity.
- Missed Dose - If a dose is missed, take it as soon as remembered unless it is less than 8 hours later; then skip the missed tablet and resume the regular schedule.
- Drug Interactions - Avoid concurrent use of other β-blockers, calcium-channel blockers (especially verapamil), or potent CYP2D6 inhibitors without dose adjustment.
- Lifestyle Integration - Combine medication with regular aerobic exercise, low-sodium diet, and stress-management techniques for optimal blood-pressure control.
Understanding Side Effects and How to Manage Them
- Common Effects - Fatigue, cold extremities, and mild gastrointestinal discomfort stem from reduced sympathetic tone and peripheral vasoconstriction. Light-intensity exercise and appropriate clothing can mitigate cold-hand/foot sensations.
- Bradycardia or Dizziness - If heart rate falls below 50 bpm or you experience significant dizziness, contact your clinician; dosage reduction may be necessary.
- Bronchospasm - Non-selective β₂ blockade can exacerbate asthma; patients with reactive airway disease should be monitored closely or switched to a cardio-selective β-blocker.
- Mood Changes - Rarely, propranolol may provoke depressive symptoms. Reporting mood alterations promptly allows for timely assessment.

Frequently Asked Questions
What makes the extended-release formulation different from regular propranolol tablets? The LA tablet uses a matrix that releases propranolol gradually over 24 hours, allowing once-daily dosing and reducing peaks that can cause side-effects such as tremor or abrupt heart-rate changes.
Can I use Inderal La for acute migraine attacks? Inderal La is intended for migraine prevention, not acute relief. For breakthrough attacks, triptans or NSAIDs are recommended according to your physician’s guidance.
Is it safe to combine Inderal La with other blood-pressure medicines? Co-administration with ACE inhibitors, diuretics, or calcium-channel blockers is common, but dose adjustments may be needed to avoid excessive blood-pressure reduction. Always discuss combination therapy with your prescriber.
Will Inderal La affect my ability to exercise? Beta-blockers can lower maximal heart-rate response, so perceived exertion may feel higher at a given workload. Adjusting exercise intensity and monitoring heart rate zones can help maintain a safe routine.
How quickly will I notice a reduction in migraine frequency? Most patients observe a noticeable decrease after 4-6 weeks of consistent daily dosing, though full therapeutic effect may take up to 12 weeks.
Is Inderal La appropriate for performance anxiety before a public speech? A single low dose taken 1-2 hours before the event can blunt the physical symptoms of anxiety without compromising cognition. This off-label use should be discussed with a healthcare professional beforehand.
Can the medication be taken with alcohol? Alcohol can enhance propranolol’s blood-pressure-lowering effects and increase fatigue. Moderation and close monitoring are advisable.
What should I do if I experience severe shortness of breath? Severe dyspnea may signal bronchospasm, especially in asthmatic individuals. Stop the medication and seek immediate medical attention.
Is there a generic version of Inderal La available locally? Yes, several manufacturers supply generic propranolol extended-release tablets that meet Singapore’s regulatory standards, offering comparable efficacy at lower cost.
Will Inderal La interfere with my sleep patterns? Some patients report mild insomnia, likely due to central nervous system effects. Taking the dose in the morning and avoiding late-day dosing usually mitigates this issue.
