Semaglutide & GLP-1 Weight Loss in Irvine
Mounjaro, Zepbound, Ozempic, Wegovy — brand name GLP-1s, physician-prescribed in Irvine CA.
Last updated October 2026
Weight loss that lasts — physician-prescribed, FDA-approved, brand name only.
You've tried the diets. You've tried the exercise programs. If you're still struggling to lose weight and keep it off, the problem may not be willpower — it may be biology. GLP-1 medications work by targeting the hormonal pathways that regulate appetite and metabolism. If you're searching for tirzepatide near me, semaglutide near me, or a weight loss clinic near me in Irvine or Orange County — you've found the right place.
At The Pur Health in Irvine, CA, Sabeen Munib M.D. has been prescribing GLP-1 medications for years. Every patient receives a personalized consultation, individualized dosing, and ongoing physician support — not a telehealth app or a one-size-fits-all protocol.
Brand name only: The Pur Health prescribes only FDA-approved, brand-name GLP-1 medications — Wegovy, Zepbound, Ozempic and Mounjaro. We do not offer compounded or generic versions.
Mounjaro and Zepbound (Tirzepatide) — why Dr. Munib recommends it for most patients
Mounjaro (tirzepatide) is a dual GIP/GLP-1 receptor agonist — it works on two appetite hormones instead of one.
Zepbound is the FDA-approved weight loss version of tirzepatide. Mounjaro is the same medication, approved for type 2 diabetes.
Cost: treatment is a fixed-cost prescription visit with follow-ups, and Dr. Munib gives you the cost at your appointment. If your medication is given in the office, that is a cash visit, also brand-name only. All dosing decisions are made by Dr. Munib personally based on your response and tolerance.
Ozempic and Wegovy (Semaglutide) — a trusted option with strong clinical evidence
Semaglutide (sold as Ozempic for diabetes and Wegovy for weight loss) is a GLP-1 receptor agonist with years of clinical evidence behind it. It mimics the GLP-1 hormone — telling your brain you're full and slowing gastric emptying — leading to reduced calorie intake and sustainable weight loss.
Semaglutide has the longest track record of the GLP-1 medications. Ozempic may be preferred for patients with type 2 diabetes, and it has better insurance coverage than Mounjaro for diabetic patients. Wegovy is specifically FDA-approved for weight loss.
Insurance coverage: some insurance plans cover Ozempic or Mounjaro if you have type 2 diabetes. Coverage for weight loss alone is rare but increasing. Dr. Munib will review your eligibility and help you navigate coverage options during your consultation.
Physician-supervised weight loss with Sabeen Munib M.D.
GLP-1 medications are not candy dispensed by a telehealth app. They are prescription medications that require proper medical evaluation, dose management, and monitoring. At The Pur Health, Dr. Munib personally reviews your health history, metabolic goals, and current medications before prescribing anything.
Unlike telehealth-only services or medspa weight loss programs, The Pur Health is a full-service medical practice. Dr. Munib treats you as a whole patient — managing the intersection of weight, metabolic health, cardiovascular risk, and overall wellness. Your weight loss plan is coordinated with your overall care.
Primary care + weight loss under one roof: The Pur Health is in-network with most PPO plans for primary care services. Patients who use Dr. Munib as their primary care physician benefit from fully integrated care between their medical and weight loss treatment.

From consultation to your first injection: your weight loss experience at The Pur Health
Consultation (30 minutes) — Dr. Munib reviews your complete health history, current medications, metabolic goals, and weight history. She will determine which medication — Mounjaro, Zepbound, Ozempic, or Wegovy — is most appropriate for your individual profile.
Starting dose — all GLP-1 medications are started at the lowest dose and titrated up gradually based on your tolerance. This minimizes side effects and gives your body time to adjust.
Ongoing support — follow-up visits to monitor progress, adjust dosing, and address any side effects. Dr. Munib's team is available between visits for questions and support.
Results — most patients notice appetite reduction within the first 1–2 weeks. Meaningful weight loss typically begins at weeks 4–8. Full results develop over 3–12 months with continued treatment.
Are you a candidate for Mounjaro, Zepbound, Ozempic, or Wegovy?
GLP-1 medications may be right for you if:
- Your BMI is 30 or higher (obese), or 27+ with a weight-related condition such as diabetes, hypertension, or high cholesterol
- You've struggled to lose weight with diet and exercise alone
- You do not have a personal or family history of medullary thyroid cancer or MEN2 syndrome
- You are not currently pregnant or planning to become pregnant
- You are willing to commit to lifestyle modifications alongside medication
During your consultation, Dr. Munib will review your full health history and confirm whether GLP-1 therapy is appropriate for you. She will also discuss realistic expectations, potential side effects, and what success looks like for your specific goals.
Mounjaro vs. Ozempic: which GLP-1 medication is right for you in Irvine?
Choose Mounjaro or Zepbound (Tirzepatide) if: you want a medication that works on two appetite hormones, you don't have diabetes (Zepbound is FDA-approved specifically for weight loss), and you're comfortable with a higher out-of-pocket cost.
Choose Ozempic or Wegovy (Semaglutide) if: you have type 2 diabetes and want better insurance coverage, you prefer a medication with a longer track record, or you've had difficulty tolerating dual GIP/GLP-1 agonists in the past.
The right choice depends on your health history, budget, and goals. That's what the consultation is for.
Why The Pur Health does not offer compounded or generic GLP-1 medications
You've seen the ads — compounded semaglutide for $99/month, generic tirzepatide available online. We don't offer them. The Pur Health prescribes only FDA-approved, brand-name GLP-1 medications.
When a medication is sold well below market cost, it's worth asking what's actually in it. These are injected medications — uncontrolled impurities are a real risk. We educate every patient who asks about compounded options, and we will not compromise your safety for a cheaper price.
At The Pur Health: we prescribe only FDA-approved, brand name medications dispensed by licensed pharmacies. Ozempic, Wegovy, Mounjaro, Zepbound — the real thing, at a fair price, under physician supervision.

Who comes to us for GLP-1 weight loss
Most people who book a weight loss visit have more going on than the number on the scale. Dr. Munib looks at the whole picture, because the conditions that come with extra weight change which medicine fits and what else needs care.
Weight gain in perimenopause or menopause
Weight often shifts to the waist in midlife, and sleep, mood and hot flashes make it harder to manage. A GLP-1 medicine treats the weight. If menopause symptoms are part of the picture, HRT can be planned at the same visit.
Prediabetes, insulin resistance or PCOS
Losing even 5 to 10 percent of your weight can improve blood sugar. GLP-1 medicines are not approved for PCOS itself, but they may be used for weight in women with PCOS who qualify. They are stopped before a planned pregnancy.
Sleep apnea or high blood pressure
Zepbound is FDA-approved to treat moderate to severe obstructive sleep apnea in adults with obesity. Blood pressure often comes down as weight comes off, so it is checked at follow-ups and other medicines are adjusted if needed.
You stopped a GLP-1 and the weight came back
This is common and not a failure. Dr. Munib reviews why you stopped, such as side effects, cost or supply, and plans a restart or a different medicine.
Labs such as A1c, cholesterol, kidney and liver tests may be ordered or reviewed at your first visit, so the plan treats the whole problem.
How long does semaglutide take to work?
Many people notice less hunger within the first weeks. Weight loss is gradual, because the dose starts low and goes up every 4 weeks to limit side effects.
Wegovy (semaglutide)
Starts at 0.25 mg once a week and steps up every 4 weeks. Most people reach the usual dose of 2.4 mg at about week 17.
Zepbound (tirzepatide)
Starts at 2.5 mg once a week. The dose can go up by 2.5 mg after at least 4 weeks, to 5, 10 or 15 mg.
What to expect over a year
Weight loss builds over the first year as the dose goes up. How much you lose depends on the medicine, the dose you reach, and your eating and activity, which is why Dr. Munib checks your progress at each follow-up.
Muscle loss, protein and hair shedding on GLP-1s
These medicines take off more fat than muscle, but some of the weight lost is muscle. Hair shedding can also happen as weight comes off. Both are easier to manage when planned for from the start.
- Eat protein at every meal, and start meals with it when your appetite is small
- Strength training two or more days a week helps protect muscle
- Hair loss was reported more often in women than men on Wegovy and Zepbound, and was linked to weight loss
- A body composition scan can track muscle and fat, not just weight
- Tell Dr. Munib about hair shedding: iron, thyroid and other causes can be checked
Semaglutide side effects and how to handle nausea and constipation
Nausea, diarrhea, vomiting, constipation, stomach pain, heartburn and burping are the most common side effects. They are usually worst after starting or raising the dose.
What helps
Smaller meals, stopping when you feel full, and going easy on fried and fatty food. Drink enough water: losing fluid from vomiting or diarrhea can strain the kidneys. A dose increase can be delayed if you are not ready.
Call us right away for
Severe stomach pain that may spread to your back, pain in the upper right belly with fever or yellow skin or eyes, signs of an allergic reaction, or vomiting you cannot keep fluids down with.
Before surgery or sedation
Tell your surgeon and anesthesia team that you take a GLP-1. Food can stay in the stomach longer, which matters for anesthesia.
What happens when you stop semaglutide or tirzepatide?
Appetite usually comes back after stopping, and most people regain a large part of the weight within a year. People who stopped Wegovy regained about two-thirds of the weight they had lost a year later. People who kept taking Zepbound kept losing weight, while those who stopped regained much of it.
- Plan the long term with Dr. Munib before you stop
- Some people stay on a maintenance dose; others taper while habits and muscle are built up
- If you have stopped already, a restart begins at a low dose again

Call (949) 647-5234How much does Mounjaro cost at The Pur Health in Irvine?
GLP-1 treatment at The Pur Health, including Mounjaro, is a fixed-cost prescription visit with follow-ups, and Dr. Munib gives you the cost at your appointment. Medication given in the office is a cash visit, also brand-name only. We prescribe only FDA-approved brand-name medications: Wegovy, Zepbound, Ozempic and Mounjaro.
Does insurance cover Mounjaro or Ozempic for weight loss?
Some insurance plans cover Ozempic or Mounjaro if you have type 2 diabetes. Coverage for weight loss alone is rare but increasing — Wegovy has slightly better coverage than Ozempic for weight loss indications. Dr. Munib will review your specific plan during your consultation. The Pur Health accepts most major PPO plans for primary care services.
What is the difference between Mounjaro and Ozempic?
Mounjaro (tirzepatide) works on two appetite hormones, GLP-1 and GIP. Ozempic (semaglutide) works on GLP-1 only and has the longer track record. Zepbound is the FDA-approved weight loss version of tirzepatide; Wegovy is the FDA-approved weight loss version of semaglutide. Dr. Munib helps you choose based on your health history, budget and goals.
Do you offer compounded semaglutide?
No. The Pur Health prescribes only FDA-approved, brand-name GLP-1 medications — Ozempic, Wegovy, Mounjaro and Zepbound — dispensed by licensed pharmacies. We do not offer compounded or generic versions.
How much weight can I expect to lose on Mounjaro or Ozempic?
It depends on your dose, health history and habits. Dr. Munib sets realistic goals with you at your consultation and adjusts your plan as you go.
How do I get started with weight loss treatment at The Pur Health?
Book a weight loss consultation at our Irvine office. Dr. Munib will spend approximately 30 minutes reviewing your health history, current medications, and weight loss goals. She will recommend the most appropriate GLP-1 medication and starting dose. The Pur Health is located in Irvine, CA 92618 and accepts most major PPO plans for primary care services.
Where can I get semaglutide near me in Irvine?
At The Pur Health, 114 Pacifica, Suite 280, Irvine, CA 92618. Dr. Munib sees patients in person from across Orange County, including Costa Mesa, Tustin, Newport Beach and Lake Forest.
Who qualifies for Wegovy, Ozempic, Zepbound or Mounjaro?
For weight loss, usually adults with a BMI of 30 or higher, or 27 or higher with a weight-related condition such as high blood pressure, prediabetes or high cholesterol. Ozempic and Mounjaro are approved for type 2 diabetes. Dr. Munib reviews your history and labs before prescribing.
Who should not take a GLP-1 medicine?
Anyone with a personal or family history of medullary thyroid cancer or MEN2, anyone pregnant, and anyone who has had a serious allergy to the medicine. Severe gastroparesis, past pancreatitis, gallbladder disease and diabetic eye disease need a careful review first.
How long does it take for semaglutide to start working?
Many people feel less hungry within the first weeks. Weight loss builds over months as the dose is raised every 4 weeks, and most people reach the usual Wegovy dose at about week 17.
Will I lose muscle on Ozempic or Zepbound?
Some of the weight lost is muscle, though more fat than muscle is lost. Protein at every meal and strength training help protect muscle, and a body composition scan can track it.
How do I prevent hair loss on Ozempic?
Hair shedding is linked to weight loss and is more common in women. Enough protein, slower weight loss and checking iron and thyroid can help. Tell Dr. Munib if you notice it.
What should I eat on semaglutide?
Small meals built around protein, vegetables, fruit, whole grains and water. Fried, fatty and very sweet foods tend to make nausea worse. Nutrition counseling can build a plan around your appetite.
Can I take a GLP-1 if I have PCOS or prediabetes?
Often, yes, if your weight qualifies. Losing weight can improve blood sugar and PCOS symptoms. Dr. Munib reviews pregnancy plans and birth control first, because GLP-1 medicines are not used in pregnancy.
Will I gain the weight back if I stop?
Most people regain much of the weight within a year of stopping. Dr. Munib plans the long term with you, including maintenance doses, protein, strength training and follow-up.
Do you treat Ozempic face?
Facial volume loss after weight loss is treated at our sister practice, Spectrum Skin Clinic. Our skin after weight loss page explains the options.
