How they work, who they’re for, and what to expect
Performance anxiety is one of the most common forms of situational anxiety. It tends to appear in high-stakes moments — public speaking, interviews, presentations, auditions, competitive events, or important meetings. Many people who experience it are otherwise confident and well-prepared.
What often surprises people is that the most disruptive symptoms are physical, not mental.
Your heart races.
Your hands shake.
Your voice trembles.
You flush or sweat.
Your breathing feels shallow.
These symptoms can escalate quickly because once you notice them, anxiety increases — which intensifies the physical response. That feedback loop is where beta blockers can help.
Beta blockers are medications originally developed for cardiovascular conditions such as high blood pressure, irregular heart rhythms, angina, and migraine prevention.
They work by blocking beta-adrenergic receptors — the receptors that respond to adrenaline (epinephrine) in the body.
When adrenaline binds to these receptors, it increases heart rate, blood pressure, and muscle tension. Beta blockers blunt that response.
Common beta blockers include propranolol, atenolol, and metoprolol. For performance anxiety specifically, propranolol is most often used because it effectively reduces tremor and heart rate in short-term situations.
When you step into a stressful situation, your body activates the “fight or flight” response. Even if you’re mentally calm, your nervous system may surge.
Beta blockers do not eliminate anxiety thoughts. They do not change emotional processing. They do not sedate you at typical performance doses.
What they do is reduce the body’s amplification of stress.
By lowering heart rate and dampening tremors, they prevent physical symptoms from spiraling. For many people, once the body calms down, confidence improves naturally.
It becomes easier to focus on the task instead of your heartbeat.
Beta blockers are most appropriate for situational anxiety that is predictable and performance-specific.
They may be helpful if:
Your anxiety is limited to specific events
Physical symptoms are the main problem
You perform well in other settings
You do not have daily or generalized anxiety
Examples include public speaking, courtroom appearances, stage performances, board presentations, or high-pressure testing environments.
They are typically taken 30 to 60 minutes before the event, allowing the medication to take effect before adrenaline peaks.
Beta blockers are not designed to treat chronic anxiety disorders, panic disorder, or ongoing intrusive thoughts.
They may not be appropriate for individuals with:
Asthma or reactive airway disease
Very low resting heart rate
Certain cardiac conduction disorders
Uncontrolled diabetes
Low blood pressure
Because they affect heart rate and circulation, medical history must be reviewed before prescribing.
At low, situational doses, beta blockers are generally well tolerated.
Possible side effects may include:
Mild fatigue
Lightheadedness
Cold hands or feet
Slower heart rate
At higher doses, they may reduce exercise tolerance.
Importantly, they are not habit-forming and do not cause dependence.
Unlike benzodiazepines, they do not impair cognition or cause sedation at typical performance doses. Most people remain mentally sharp.
This is a common concern.
Beta blockers do not suppress emotions or erase anxiety entirely. Instead, they interrupt the body’s feedback loop. When physical symptoms are reduced, the brain often interprets the situation as less threatening.
For some people, this experience builds confidence over time.
However, if anxiety is frequent, generalized, or impairing across many areas of life, therapy, behavioral strategies, or other medications may be more appropriate.
Beta blockers can be an effective option for performance anxiety when physical symptoms interfere with otherwise strong preparation and capability.
They are not a cure for anxiety. They are a targeted tool for predictable, situational stress.
If you’re unsure whether beta blockers are appropriate — or whether your anxiety pattern suggests another approach — a licensed medical provider can review your history and determine what fits your needs safely.

Chlamydia vs Gonorrhea vs Trichomoniasis
How these common STIs differ in symptoms, testing, and treatment
Chlamydia, gonorrhea, and trichomoniasis are among the most common sexually transmitted infections (STIs) worldwide. Because they can cause similar symptoms — or no symptoms at all — they are often confused with one another.
Understanding how they differ helps ensure proper testing, treatment, and prevention.

10 Fast Food Meals That Support a GLP-1 Diet
If you’re taking a GLP-1 medication like Ozempic®, Wegovy®, Mounjaro®, or Zepbound®, you’ve probably noticed some big shifts in how you feel around food—smaller appetite, slower digestion, and maybe even sensitivity to meals that used to sit just fine. These medications can be powerful tools for weight loss and blood sugar control, but what you eat still plays a major role in how well they work.
Part of taking a GLP-1 means being mindful about what your body needs—getting enough protein to protect muscle, choosing fiber-rich carbs for digestion and energy, drinking plenty of water, and eating smaller portions that won’t overwhelm your system.
Eating at home is usually the healthier, more controlled option—but real life doesn’t always go as planned. Whether you're traveling, in a rush, or just craving something quick and familiar, it helps to know which fast food options fit into the recommended GLP-1 diet without leaving you feeling uncomfortable or off track. With the right approach, you can still enjoy fast food—without sacrificing progress.
Below, we’ll cover healthy fast food options that fit your goals, how to choose wisely at any restaurant, and a few tips to support your progress beyond what’s on your plate.

How much do glp-1 injections cost?
GLP-1 receptor agonists have quickly become some of the most talked-about medications for both weight loss and Type 2 diabetes. These injectable drugs mimic a natural hormone that helps regulate blood sugar, curb appetite, and support weight management. With names like Ozempic, Wegovy, and Mounjaro in the headlines, many people are asking the same question: How much is a GLP-1 without insurance?
GLP-1 (glucagon-like peptide-1) injections are a class of medications that help the body lower blood sugar and promote a feeling of fullness after eating. While originally developed for diabetes, several have been FDA-approved for weight loss as well. Some also include additional mechanisms—for example, Mounjaro and Zepbound combine GLP-1 with GIP (glucose-dependent insulinotropic polypeptide) for added effect.
Here are some of the most commonly prescribed GLP-1 and dual agonist injections:
Costs for GLP-1 injections can vary widely depending on the medication, dosage, and whether you have insurance. Below are average monthly GLP-1 prices for popular options when paying out of pocket.
Ozempic typically costs around $1,000 without insurance. It’s dosed weekly and used primarily for managing Type 2 diabetes, although it’s often prescribed off-label for weight loss.¹
Wegovy costs around $1,300 per package out-of-pocket. It contains the same active ingredient as Ozempic (semaglutide) but is FDA-approved for chronic weight management.²
Saxenda runs about $1,300 per month and is taken as a daily injection. It uses liraglutide, another GLP-1 receptor agonist, to promote weight loss and appetite control.³
Mounjaro, a dual GIP/GLP-1 receptor agonist, ranges from $1,000 per refill when not covered by insurance. It’s primarily used for diabetes but has gained popularity for weight loss as well.⁴
Zepbound, which uses the same active ingredient as Mounjaro but is approved for weight loss, costs about $1,000 per fill without insurance.⁵
The cost of compounded semaglutide can vary based on the pharmacy and formulation. It's often considered a more affordable option, but prices depend on the provider and dosage prescribed.
