Inderal Dosage: Various Forms, Strengths, Administration, and Further Details
Inderal LA and Inderal XL, both belonging to the drug class called beta-blockers, are primarily used to manage conditions such as high blood pressure and heart problems. However, they are also used off-label for treating anxiety, tachycardia, and tremors.
Anxiety
For anxiety, particularly performance or situational anxiety, Inderal helps reduce physical symptoms such as rapid heartbeat, trembling, and nervousness. Typical doses for anxiety range around 10-20 mg taken 1-2 times daily or as needed, with some users taking doses up to 30-40 mg before anxiety-provoking events. The effect onset is usually within 30 minutes and lasts for 4-6 hours.
Tachycardia
In cases of tachycardia, especially those related to hyperthyroidism or other causes of elevated heart rate, Inderal is commonly used to block beta-adrenergic receptors, reducing heart rate effectively. The off-label dosages for tachycardia vary by clinical situation, and they are often similar to those used for hypertension or arrhythmias, adjusted based on response and tolerance.
Tremors
Inderal is widely recognised and frequently prescribed off-label for benign essential tremors. Patients report significant improvement with Inderal, sometimes on the order of doses like 40-120 mg daily, often divided. Improvement can be noticed quickly, but the dosage must be tailored to balance efficacy and side effects like dizziness or fatigue.
Typical Dosage Ranges for Off-Label Uses
| Condition | Dose Range | Notes | |-----------------|--------------------------------|------------------------------------------| | Anxiety | 10-20 mg 1-2 times daily | For performance anxiety, 30-40 mg ~1 hr before events | | Tachycardia | Variable, often 40-120 mg/day | Titrate based on heart rate and symptom control | | Tremors | 40-120 mg/day | Divided doses; monitor for dizziness and hypotension |
Additional Considerations
It's important to note that Inderal can cause side effects such as dizziness, fatigue, and hypotension, especially at higher doses. Abrupt discontinuation should be avoided due to the risk of rebound tachycardia or angina exacerbation. Its use requires caution in patients with asthma or other respiratory conditions as it can cause bronchospasm.
Individual dosing should always be guided by clinical response and physician supervision. If you take more Inderal than prescribed, call your doctor immediately or contact America's Poison Centers at 800-222-1222.

Inderal LA and Inderal XL come as extended-release oral capsules that release the active ingredient (propranolol) slowly over time. They are available in a generic version and are brand-name drugs prescribed for high blood pressure.
Inderal LA is approved for preventing migraine episodes, decreasing the frequency of angina occurrences and increasing exercise tolerance in people with stable angina, and easing symptoms of hypertrophic subaortic stenosis. The typical dosage for Inderal LA for high blood pressure is 80-640 mg daily. For high blood pressure, the typical dosage for Inderal XL is 80-120 mg daily.
