Overview
Inderal LA is a special long-acting formulation of a propranolol, the pre-eminent member of a class medicines called beta blockers. That means these drugs work in part by blunting the action of adrenaline, the body's natural fight or flight chemical.
People normally respond to stressful situations with a rapid pulse, a pounding heart and an increase in blood pressure. Inderal LA helps block such reactions.
Inderal LA is prescribed for a wide range of health conditions including irregular heart rhythms, angina, high blood pressure, prevention of migraine headaches or a second heart attack and tremor.
Although the FDA has not specifically approved its use for other purposes, doctors have employed Inderal LA to relieve involuntary movements caused by major tranquilizers, stage fright and panic disorders.
The dose will vary depending upon the condition being treated.
Side Effects and Interactions
Inderal LA can cause a number of side effects.
They include slow heart rate, cold hands and feet, insomnia, nightmares, blurred vision, sexual difficulties, nerve tingling, dizziness, nausea, stomach ache, gas, diarrhea, indigestion, rash, arthritis and muscle pain.
This medicine may also have a negative effect on cholesterol and other blood fats so a lipid test before treatment and periodically thereafter would be prudent.
Inderal LA is a little more likely to affect the nervous system than certain other drugs in this class.
Be alert for the beta blocker blues. Symptoms of psychological depression, fatigue, decreased concentration, memory loss and mood swings may come on slowly and insidiously.
Notify your physician promptly of any adverse reactions, especially breathing difficulties, fluid retention in the legs or a night cough.
Inderal LA can interact with a number of other compounds, including several that are used to treat asthma, colds, allergies, diabetes, and heart problems.
Arthritis medicine and aspirin may also reduce the effectiveness of some beta blockers.
Propranolol may be incompatible with the herb astragalus.
Check with your doctor and pharmacist to make sure Inderal LA is safe in combination with any other drugs or herbs you may take.
Special Precautions
Some people should rarely, if ever, take beta-blockers such as Inderal.
Asthmatics and patients with other respiratory problems are especially vulnerable, because these drugs can make breathing worse.
People with heart failure must also be extremely cautious if prescribed beta-blockers because the medicine could lead to cardiac complications.
Never stop taking any beta-blocker medication abruptly unless you are under very close medical supervision. Angina or a heart attack could occur.
These drugs may also make treatment of diabetes and thyroid disorders more complicated.
Your doctor can tell you what additional tests and precautions you will need in managing these conditions.
Taking the Medicine
Inderal LA is more convenient than regular Inderal because its sustained release formulation provides blood levels that last substantially longer in the body. This means that most people only need to take one capsule a day.
To maintain a constant level of the medicine in your system, try to maintain a regular regimen, taking Inderal LA at roughly the same time each day.

I am on Amitriptyline, Propranolol Hydrochloride and Paracetomol to take care of my migraines. I thought I had enough for two nights, but I found I did not and I forgot to pick up my medication before the NHS Health Service closed for the weekend. As a result, I went three nights without taking my medication. I picked it up on the Monday but as I was going to be driving, I decided to hold off taking the medication until that night. That afternoon, I fainted. I believe this happened because I had missed taking my medication. Has anyone else experienced this kind of reaction.?
I take this medication to slow my heart rate down, due to hyperthyroidism.
The side affects I get are upset stomach and gas like crazy. They taste really bad and I am tired all the time but cannot sleep. Other than that my pulse has gone down quite a bit.
I've been taking Inderal LA for years - I was on 80 but was increased to 120 a year or so ago. I have a mitral prolapse valve and a slight heart murmur - not life threatening, to be sure, but can be scary. The irregular heartbeat (although it doesn't really "stop", it feels like my heart stops beating and/or "skipping") is so annoying and frightening, particularly when driving - feels like I'm going to faint.
About the only thing I can do is cough real hard - kind of a "jump start" to get the beat back on track. I'm 62 and have lived with this all my life. The Inderal does the trick. I will most likely have to take it the rest of my life. The "pros" outweigh the "cons" for me! And, in conclusion, I have never had any of the aforementioned side effects at all.
