Propranolol 40mg Tablets information
What is Propranolol and what is it used for?
Propranolol Tablets are a type of medication known as a beta-blocker and are often the first treatment choice for preventing migraines. They are very effective at reducing the frequency of migraines when taken daily helping sufferers manage their symptoms that otherwise may be debilitating and significantly affecting their daily lives.
You may want to consider the use of Propranolol to manage migraines if the following indications apply for you:
- You suffer between 2-8 headaches a month.
- Your headaches are less frequent but more prolonged (more than 2 days) or you have severe attacks leading to substantial disability.
- You cannot take other prescription migraine treatments or you have other conditions.
- Your migraines are predictable in occurrence.
- You have tried other prescription treatments but they have not worked, or you are using them often.
- You have suffered unwanted effects from other migraine treatments.
- You have taken regular treatments which could be considered as overuse. Medication overuse is defined as the use of combination analgesics, opioids or triptans ten days each month or the use of simple analgesics (paracetamol, non-steroidal anti-inflammatory drugs [NSAIDs] or aspirin) 15 days a month or more.
Propranolol is available on prescription for adults over the age of 18 years. Each box contains 84 tablets and should be taken exactly as directed.
What is a migraine?
In The UK, migraine headaches affect approximately 25% of women and 8% of men. The condition is believed to be partially hereditary, meaning a person may be more prone if a blood relative also suffers from the condition. It is thought that migraine headaches are caused by the blood vessels becoming dilated and inflamed within the brain.
Several factors can trigger a migraine attack, including;
- a poor diet
- excessive alcohol consumption
- too much caffeine
- not getting enough sleep
- for some women, their monthly period can trigger a migraine attack
A migraine sufferer will likely find that the most severe attacks can completely disrupt their day, causing nausea, light sensitivity, and intense throbbing pain. Many sufferers also experience a heightened intolerance to loud noises and strong smells. Taking Propranolol will help to prevent these symptoms as well.
Approximately one in every four migraine sufferers will experience some form of pre-migraine warning, which is known as an aura. This can involve visual cues, such as blurred or distorted vision. Alternatively, a sufferer may experience a silent migraine, where the aura occurs but a migraine attack does not follow.
On average, a migraine will last for a few hours, but for some, it can continue for as long as three days. After a migraine has passed, the sufferer may continue to feel fatigued for several subsequent days.
How does Propranolol work?
Beta-blockers such as Propranolol work mainly by slowing down the heart and the pressure at which the blood circulates the body. They do this by blocking the action of hormones like adrenaline. The action of Propranolol on the heart and circulation helps prevent migraines as they prevent the blood vessels in the brain from becoming dilated.
How long does Propranolol take to work?
Unfortunately, many physicians discontinue treatment before the drug has had a chance to work. Propranolol may take six to twelve weeks to be effective with increased dosages as the weeks go by. For this reason, you should continue to use painkillers and prescription treatments if you develop a migraine during this time.
