The Best Weight Loss Meds Available Right Now
The best weight loss meds currently available by prescription are ranked below by average weight loss results from clinical trials:
| Medication | Brand Name | Type | Avg. Weight Loss |
|---|---|---|---|
| Tirzepatide | Zepbound | Injectable | Up to 22.5% |
| Semaglutide | Wegovy | Injectable or pill | ~14-17% |
| Liraglutide | Saxenda | Injectable | ~5-6% |
| Phentermine-topiramate | Qsymia | Pill | ~8-10% |
| Naltrexone-bupropion | Contrave | Pill | ~4-5% |
| Orlistat | Xenical/Alli | Pill | ~3% |
Obesity affects more than 4 in 10 adults in the United States. It’s not a willpower problem — it’s a chronic disease with real biological drivers.
The good news? The last few years have brought genuinely remarkable advances in prescription weight loss treatment. Drugs like tirzepatide and semaglutide are producing results that were unheard of just a decade ago — levels of weight loss that once required bariatric surgery.
But with more options comes more confusion. Injectable or pill? Brand name or generic? Which drug works best for your health history, budget, and lifestyle?
This guide breaks it all down clearly, so you can walk into your next appointment informed and ready.
I’m Ana Vinikov, Practice Manager at Global Clinic, where our multidisciplinary team helps patients across Northern Chicago navigate complex health decisions — including finding the best weight loss meds for their unique situation. With over 20 years of experience in patient-centered care, I’ll walk you through everything you need to know to make a confident, well-informed choice.
Comparing the Best Weight Loss Meds: Injectables vs. Pills
When we talk about the best weight loss meds, the conversation usually splits into two camps: the high-tech injectables (like Wegovy and Zepbound) and the traditional oral pills (like Qsymia and Contrave). Choosing between them isn’t just about how much weight you’ll lose; it’s about how the medication fits into your daily life.
Injectables have stolen the headlines recently because their results are, frankly, staggering. In the SURMOUNT-1 trial, people taking tirzepatide (Zepbound) lost an average of 22.5% of their body weight over 72 weeks. To put that in perspective, if you weigh 250 pounds, that’s a 56-pound loss. Semaglutide (Wegovy) isn’t far behind, showing a 14.9% average weight loss in its STEP 1 trial.
Pills, on the other hand, offer a level of convenience that many of our patients in Arlington Heights and Crystal Lake prefer. There are no needles to store in the fridge, and for some, the cost is significantly lower. While the weight loss percentages are generally lower—ranging from 3% to 10%—they can be the perfect “adjunctive therapy” when combined with a solid nutrition and exercise plan.
| Feature | Injectables (GLP-1/GIP) | Oral Pills (Traditional) |
|---|---|---|
| Frequency | Once weekly (mostly) | Once or twice daily |
| Weight Loss Potential | High (15% – 22%+) | Moderate (3% – 10%) |
| Common Side Effects | Nausea, vomiting, diarrhea | Dry mouth, insomnia, constipation |
| Storage | Often requires refrigeration | Shelf-stable |
| Cost | Generally higher ($1,000+/month) | Generally lower (varies) |
A head-to-head trial recently showed that Zepbound (tirzepatide) actually generated superior weight loss compared to Wegovy (semaglutide), with average losses of 20.2% vs. 13.7%. However, “best” is subjective. If you have a phobia of needles or a history of specific thyroid issues, a pill might be your personal winner.
GLP-1 and GIP Agonists: The Best Weight Loss Meds for Results
If you’re looking for the heavy hitters, you’re looking at GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide) receptor agonists. These medications mimic natural hormones in your body that tell your brain you’re full and tell your stomach to slow down.
- Zepbound (Tirzepatide): This is the only dual agonist currently on the market, targeting both GLP-1 and GIP receptors. This “double-barreled” approach is why it currently holds the crown for the highest average weight loss.
- Wegovy (Semaglutide): The drug that started the current craze. It mimics GLP-1 and is approved for long-term weight management in adults and children aged 12 and older.
- Saxenda (Liraglutide): An older GLP-1 that requires a daily injection. While it leads to less weight loss than the weekly options (about 5-6% more than lifestyle changes alone), it has a long track record of safety.
These drugs don’t just “burn fat.” They fundamentally change your relationship with food by reducing “food noise”—those intrusive thoughts about your next meal. They also slow down “gastric emptying,” meaning food stays in your stomach longer, keeping you satisfied on smaller portions.
Because these are powerful medications, they are strictly FDA-approved for chronic weight management in specific populations. We often see patients who have struggled for years with “yo-yo” dieting finally find stability with these options. If you’re curious about how these fit into a broader health plan, you can find more info about medical weight loss services on our site.
Oral Options: Are Pills the Best Weight Loss Meds for You?
Not everyone wants an injection, and for many of our neighbors in Schaumburg or Des Plaines, oral pills are a more accessible and affordable route.
- Qsymia (Phentermine-topiramate): This is often considered the most effective oral pill. It combines a stimulant (phentermine) to suppress appetite with a seizure/migraine medication (topiramate) that helps you feel full and makes food taste less appealing (especially sweets!). Research shows about 70% of adults lose at least 5% of their body weight on Qsymia.
- Contrave (Naltrexone-bupropion): This pill targets the reward system in your brain. It combines an addiction medication (naltrexone) with an antidepressant/smoking cessation drug (bupropion). It’s particularly helpful for those who struggle with emotional eating or intense cravings.
- Wegovy Pill (Oral Semaglutide): Yes, the “Wegovy pill” is now a reality! It’s the first oral GLP-1 for weight loss. In clinical studies, it helped people lose about 14% of their weight—comparable to the injection. It must be taken on an empty stomach with a tiny sip of water to work correctly.
- Phentermine (Adipex-P): The “old school” choice. It’s a stimulant that suppresses appetite. While it’s one of the most commonly prescribed meds due to its low cost, it is technically only FDA-approved for short-term use (up to 12 weeks), though some doctors prescribe it off-label for longer.
- Orlistat (Xenical): This one works differently. Instead of talking to your brain, it works in your gut to block about 25% of the fat you eat from being absorbed. Warning: if you eat a high-fat meal while taking this, your bathroom experience will be… memorable.
Who Qualifies for Prescription Weight Loss Treatment?
We get this question a lot at our Northbrook and Glenview locations: “Am I ‘heavy enough’ for a prescription?”
The medical community uses specific Body Mass Index (BMI) criteria to determine eligibility. Generally, you are a candidate for the best weight loss meds if:
- Your BMI is 30 or higher (obesity).
- Your BMI is 27 or higher (overweight) AND you have at least one weight-related health condition (comorbidity).
Common comorbidities include:
- Hypertension (High Blood Pressure): Losing just 5-10% of your weight can significantly lower your numbers.
- Type 2 Diabetes: Many of these meds were originally diabetes treatments because they improve insulin sensitivity.
- Sleep Apnea: Reducing neck circumference through weight loss often improves airflow during sleep.
- High Cholesterol: Weight loss helps clear triglycerides and “bad” LDL cholesterol.
These aren’t “vanity drugs” for losing those last five pounds before a wedding. They are serious medical interventions for chronic disease. You can calculate your BMI using the NIH tool to see where you stand.
Pediatric and Adolescent Use
Obesity doesn’t just affect adults. The FDA has approved several medications for children aged 12 and older, including Wegovy, Saxenda, Qsymia, and Orlistat. Setmelanotide (Imcivree) is even approved for children as young as 6, but only for those with very specific, rare genetic conditions. For teens, the focus is usually on improving health markers—like blood sugar and liver health—rather than just a number on the scale.
Navigating Insurance Coverage and Advocacy
Let’s address the elephant in the room: cost. These medications can be expensive, and insurance companies aren’t always eager to pay. However, a “denial” isn’t always the final word.
The first step is checking your Benefits Handbook. Look for “Weight Loss” or “Anti-Obesity Medications” in the pharmacy section. If it’s not there, it might be excluded entirely, which is common in some employer-sponsored plans.
If your doctor prescribes a medication and it’s denied, you can start the Appeals Process. This often requires a “Prior Authorization” (PA) where your doctor explains why the medication is a medical necessity. We suggest building a case with your healthcare team that includes:
- Documented failed attempts at weight loss through diet and exercise alone.
- A list of comorbidities (like high blood pressure) that the medication will help treat.
- An explanation of how obesity is impacting your quality of life.
Don’t be afraid to talk to your HR Department. Sometimes, employers don’t realize their insurance plan excludes obesity care. Educating them on how weight loss reduces overall healthcare costs (by preventing diabetes and heart disease) can sometimes lead to plan changes.

The Future of Obesity Medicine: Pipeline Drugs
The landscape of the best weight loss meds is changing faster than a Chicago weather forecast. There are currently dozens of new drugs in clinical trials that promise to be even more effective or easier to take.
- Retatrutide: This is a “triple agonist.” While Zepbound hits two receptors, Retatrutide hits three (GLP-1, GIP, and Glucagon). In Phase 2 trials, it showed an average weight loss of a whopping 24% in just 48 weeks. Some participants lost nearly 30% of their body weight.
- CagriSema: This combines semaglutide with a new drug called cagrilintide (an amylin analog). It targets two different hormones to help you feel full and is currently in Phase 3 trials.
- Orforglipron: This is a “small-molecule” oral GLP-1. Unlike the current Wegovy pill, it doesn’t have strict fasting requirements and could be much cheaper to produce, making it a potential “people’s pill” for weight loss.
- MariTide: This investigational drug from Amgen might only need to be injected once a month, which would be a massive win for convenience.
Researchers are also focusing on “muscle-sparing” technology. One of the downsides of rapid weight loss is losing muscle mass. New drugs in development aim to ensure that the weight you lose is strictly fat, keeping your metabolism and strength intact. You can track these and other latest research on investigational anti-obesity drugs at ClinicalTrials.gov.
Frequently Asked Questions about the Best Weight Loss Meds
How long do I need to take weight loss medications?
Obesity is a chronic condition, much like high blood pressure or asthma. For most people, these are long-term medications. When you stop taking them, your body’s “metabolic adaptation” kicks in—your hunger hormones spike, and your metabolism slows down to try and “rescue” you from what it perceives as a famine. Studies show that most people regain a significant portion of the weight if they stop the medication without a very strict, long-term maintenance plan. Think of the medication as a tool that manages the biological side of the disease while you manage the lifestyle side.
What are the most common side effects?
The most common complaints are gastrointestinal: nausea, vomiting, diarrhea, and constipation. This is because these drugs slow down your digestion. Most clinics use a titration schedule, starting you on a very low dose and slowly increasing it every four weeks to let your body adjust.
Pro-tip: Staying hydrated and eating small, high-protein meals can help manage the “queasiness” that sometimes comes with the first few days of a new dose. If you experience severe abdominal pain, it’s important to contact your doctor immediately, as rare side effects like pancreatitis can occur.
Can children or teenagers use these medications?
Yes, but it requires specialist consultation. As mentioned, Wegovy and Saxenda are FDA-approved for teens 12 and up with a BMI in the 95th percentile or higher for their age and sex. Pediatric obesity treatment focuses heavily on family-based lifestyle changes, with medication acting as a support to prevent long-term health complications like early-onset Type 2 diabetes.
