“A friend told me to take an Inderal pill before the interview. It's the confidence pill.” Many people pass Inderal around under this name before exams, interviews, and events, as if it were a simple tranquilizer. But it is a heart medication with specific uses and real contraindications. We explain what it actually does and what it does not.
What is Inderal (propranolol)?
Propranolol is an active ingredient from the beta-blocker group, and its common brand name in Egypt is Inderal. The UK's NHS explains that it slows the heartbeat and makes it easier for the heart to pump blood. The StatPearls reference notes that it dissolves in fat and crosses into the brain, which explains some of its benefits and some of its psychological side effects, such as nightmares.
What Inderal is used for
- High blood pressure, heart rhythm disorders, and angina.
- Improving the chances of survival after a heart attack.
- Preventing migraine attacks.
- Some types of tremor.
- Symptoms of an overactive thyroid, alongside its treatment.
- Physical symptoms of anxiety, which is an off-label use in the US according to the US National Library of Medicine.
Inderal for anxiety: what does it do, and what are its limits?
The NHS explains that anxiety makes the brain release adrenaline and noradrenaline, which speed up the heart and increase sweating and tremor, and that propranolol blocks the effects of these substances and so eases the physical signs. But it does not change anxious thoughts or treat the cause of anxiety. For this reason the NHS notes that many doctors prefer psychological therapy such as cognitive behavioral therapy, and Inderal may be used alongside it for a short period.
In a systematic review published in the Journal of Psychopharmacology in 2016, which included only 8 studies, no clear difference was seen between propranolol and benzodiazepines in the short-term treatment of panic attacks, but the researchers concluded that the quality of evidence was insufficient to support its routine use in any anxiety disorder. So if your anxiety is persistent, as in generalized anxiety or social phobia, you need a full treatment plan, not a pill before situations.
Side effects of Inderal
- Dizziness or vertigo, especially with the first dose.
- Tiredness and fatigue.
- Cold hands and feet.
- Sleep difficulties and nightmares.
- Diarrhea or constipation.
According to the US National Library of Medicine, symptoms that need a doctor immediately include shortness of breath, fainting, irregular heartbeat, unusual weight gain, and severe allergic reaction. As for reduced sex drive, the NHS notes that some people complain of it, but it is not a common side effect.
Who should not take Inderal?
The doctor may rule it out, because it affects the lungs and not only the heart.
An irregular or slow pulse, or heart failure, needs assessment before any beta-blocker.
It can mask the signs of low blood sugar, such as palpitations, and increase the risk of lows.
Reactions may be more severe and may not respond to the usual adrenaline.
Stopping it suddenly may worsen the symptoms of an overactive thyroid.
Combining them may lower blood pressure too much, and so can alcohol.
Is Inderal addictive? And why should it not be stopped suddenly?
Propranolol does not cause euphoria and is not classed among addictive drugs, and the NHS notes that using it for anxiety for several months or years does not appear to cause lasting harm, provided blood pressure is checked regularly. But the US label for Inderal warns that stopping it suddenly in people with heart disease can worsen angina, and heart attacks have even been reported, and it recommends reducing it gradually over weeks.
When should you ask for help?
If you depend on a pill before every social situation, if you avoid living your life because of palpitations and tremor, or if you have started turning to sedatives or alcohol to calm down, this is the time for a real assessment of your anxiety. At Eradah this starts with a free, confidential first consultation, then a plan that combines psychological and drug treatment through outpatient treatment, with a dual diagnosis program when substance use is involved.
