After you take propranolol, you might feel fatigued and exhausted more easily after intense exercise. Propranolol is not a physically addictive, habit-forming medication. However, it is possible to become accustomed to the feeling of relaxation propranolol provides, especially if you often experience performance or social anxiety. Although propranolol is used to treat certain types of anxiety, it is not a benzodiazepine like alprazolam Xanax or diazepam Valium. Propranolol belongs to a class of medications called beta blockers.
You should not drink alcohol while taking propranolol. Alcohol can interact with propranolol and cause you to feel excessively drowsy and fatigued. Propranolol is a nonselective beta blocker, meaning it can block the effects of stress hormones on beta-1, beta-2 and beta-3 receptors. Because of this, the effects of propranolol can occur in tissue outside the heart, such as the airways. Propranolol is not recommended for people with diabetes.
If you have diabetes and anxiety, you should speak to your doctor about safe treatment options before considering any medications. Many people experience performance anxiety before giving speeches or performing in front of others. Propranolol is widely used as a performance anxiety treatment by people who perform in public, from event presenters to musicians. Propranolol can interact with a range of medications, including more than 70 major interactions with other drugs.
Today, propranolol is mostly sold as a generic without a specific brand name. Propranolol is available in four different forms. In response to these messengers, the heart beats faster, blood vessels constrict, the airways relax, and the kidneys increase production of a protein that boosts blood pressure. Beta blockers subvert these processes by settling onto beta receptors and preventing the chemical messengers from binding to their receptors.
That slows the heart, improves the conduction of electrical signals in the heart, relaxes blood vessels, and lowers blood pressure. Once a mainstay for treating high blood pressure, beta blockers have been elbowed aside by newer drugs, such as ACE inhibitors, and older ones, such as thiazide diuretics. You can tell a beta blocker by its generic name — they all end in "lol.
This accounts for their different actions and side effects. More than a dozen beta blockers have been approved for use in the United States see table. They fall into three main groups. The earliest beta blockers, like propranolol, affect both beta-1 and beta-2 receptors.
Nonselective beta blockers should be used with caution, if at all, in smokers or people with asthma or other lung conditions.
A number of beta blockers, including atenolol Tenormin and metoprolol Toprol, Lopressor , were designed to block only beta-1 receptors in heart cells. Since they don't affect beta-2 receptors in blood vessels and the lungs, cardioselective beta blockers are safer for people with lung disorders. Some beta blockers do more than block beta receptors. Labetalol Normodyne, Trandate blocks alpha receptors, too. This further helps relax blood vessels. Nebivolol Bystolic stimulates the inner lining of blood vessels the endothelium to generate nitric oxide, which helps the vessels relax.
Carvedilol Coreg does both. The Oregon researchers found compelling evidence that taking a beta blocker after having had a heart attack lowers the chances of a repeat heart attack or an early death. These drugs also increase the chances of living longer and better with heart failure. The reviewers found that different beta blockers work better for different conditions.
Beta blockers are generally safe to take. What works for one person may not work at all for someone else. You may also need additional treatment options for your anxiety while taking beta-blockers, to get to the more psychological aspects. Both atenolol and propranolol come in pill form. The amount you should take depends on both the type of beta-blocker and your medical history.
Never take more than what your doctor prescribes. Depending on your symptoms, your doctor might suggest taking a beta-blocker regularly or just before stressful events. Usually, beta-blockers will be used in combination with other treatments such as therapy, lifestyle changes , and other medications.
If you take beta-blockers regularly, you may have serious withdrawal symptoms if you suddenly stop. For some people, the side effects of beta-blockers may actually cause anxiety symptoms. You should follow up with your doctor as soon as possible if you feel like taking beta-blockers is increasing your anxiety.
Beta-blockers can also interact with other medications used to treat many heart conditions and antidepressants, so make sure you keep your doctor up to date about any medications, supplements, or vitamins you take. Beta-blockers can be helpful in managing symptoms for some people with anxiety. They can advise on the best treatment plan for you that will help manage your specific symptoms.
Most people feel anxious at some point in their lives, and the feeling often goes away by itself. An anxiety disorder is different. These are not all the side effects of beta blockers. For a full list, see the leaflet inside your medicine packet.
You can report suspected side effects using the Yellow Card Scheme. For more information on the side effects of beta blockers, read about the specific medicine you take in our Medicines A to Z. Most beta blockers are taken once a day, apart from certain beta blockers that are used during pregnancy and Sotalol, which is given 2 or 3 times a day. If you forget to take a dose of your beta blocker, take it as soon as you remember, unless it is nearly time for your next dose.
In this case, just leave out the missed dose and take your next dose as normal. Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one. If you often forget doses, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.
