Propranolol (Inderal)

The generic name for Inderal is propranolol. Both versions contain the same active ingredient and work the same way to manage conditions such as high blood pressure, migraines, and anxiety-related physical symptoms.

Propranolol is not known for being addictive when taken as prescribed by a clinician. Unlike other anxiety medications like benzodiazepines, it does not create a “high” and has a very low potential for misuse. For this reason, propranolol is not a controlled substance.

Yes. Propranolol belongs to a group of medications called beta-blockers, which reduce the effects of adrenaline on the heart and blood vessels. This helps lower heart rate, blood pressure, and physical symptoms of anxiety. Propranolol may also enter the central nervous system (CNS), which could explain its effectiveness compared to other beta-blockers.

Some people may experience mild weight changes while taking propranolol, but significant weight gain is not typical.

Try to avoid alcohol while taking propranolol. Alcohol can intensify the medication’s blood-pressure-lowering effects and may increase drowsiness or dizziness.

Propranolol (Inderal) is a beta-blocker that helps control symptoms of anxiety, while Xanax (alprazolam) is a benzodiazepine that helps reduce or relieve anxious thoughts and feelings. Unlike Xanax, propranolol does not have sedative or addictive properties but also does not treat the emotional aspects of anxiety.

SSRIs such as Zoloft (sertraline) and Lexapro (escitalopram) are antidepressants that help regulate mood and anxiety through serotonin balance in the brain. Propranolol works on the body’s “fight-or-flight” response by blocking certain stress hormones. It’s typically used short-term or situationally as a “rescue” medication (i.e. for quick relief in stressful situations), while SSRIs are used for long-term anxiety management.

Propranolol can interact with other medications that affect blood pressure, heart rhythm, or mood. Consult your prescribing clinician before starting, stopping, or combining any medications or substances with propranolol.

Yes, fatigue is a possible side effect, especially when starting treatment or adjusting the dose. Discuss any ongoing tiredness with your clinician, as it may indicate that your dosage needs adjustment.

Many people use propranolol long-term under medical supervision, particularly for chronic migraine prevention or blood pressure management. Regular follow-ups are important to monitor heart rate, blood pressure, and side effects.

Both Inderal LA and Inderal XL are extended-release forms of propranolol that are typically taken once daily. The difference lies in how each formulation releases the medication. Inderal XL is formulated to release steadily over 24 hours, while Inderal LA delivers a slightly different pattern, reaching higher levels about six hours after dosing before gradually tapering off. Your prescribing clinician will determine which version is most appropriate based on your condition, dosing needs, and how your body responds to treatment.

The cost of propranolol depends on factors such as dosage strength, formulation (generic or brand-name), and pharmacy location. According to Drugs.com (accessed October 2025):

• Generic propranolol extended-release capsules generally range from about $45 to $70 for 100 capsules, depending on the strength.
• Brand-name Inderal LA extended-release capsules typically range from approximately $1,800 to $2,500 for 30 capsules, depending on dosage.
• Brand-name Inderal XL extended-release capsules are listed around $2,100 per 30 capsules at select strengths.

If you have insurance, your out-of-pocket cost will depend on your supporting diagnosis and plan type (e.g., commercial, Medicare, Medicaid) and may include a copay or coinsurance.

If taking daily, do not stop propranolol suddenly without consulting your clinician.  If taking propranolol for a brief time or only as needed, stopping propranolol as instructed by your prescribing clinician is typically not a concern. Always follow your psychiatric provider’s directions on when to stop taking medications or change dosages.

Propranolol may be prescribed for the symptoms that accompany panic attacks, though it likely will not address emotional or cognitive aspects. It is often combined with therapy or other medications for comprehensive care.

Propranolol is sometimes used to help reduce nightmares related to post-traumatic stress, though this is considered an off-label use. Only a qualified clinician should prescribe propranolol for any sleep concerns.

Possible side effects can include fatigue, dizziness when standing too quickly, slower heart rate, or upset stomach. Some people may also notice cold hands or feet, mild sleep changes, or vivid dreams. Always discuss any new or persistent side effects with your prescribing clinician.

When prescribed for short-term or performance anxiety, propranolol may begin to take effect within 30 to 60 minutes. For ongoing use, such as migraine prevention, it may take several days or weeks before you notice improvement.

Yes. Propranolol is FDA-approved as a daily medication to help prevent migraines by reducing how often they occur and how severe they become.

Propranolol should only be used during pregnancy if a clinician determines that the potential benefits outweigh possible risks. It’s important to discuss the risks and benefits of any medication for both the mother and baby with your healthcare provider.

Propranolol passes into breast milk in small amounts. A clinician should evaluate whether continuing the medication while breastfeeding is appropriate based on your health and the infant’s needs. Always follow your psychiatric provider’s directions on when to take prescription medications.

Yes. Beta-blockers help lower blood pressure by reducing heart rate and easing strain on the heart and arteries.

Propranolol is not classified as a controlled substance. It should only be taken under the supervision of a licensed clinician and as prescribed.
