Both are Novo Nordisk weight-loss injectables, but Saxenda is liraglutide (daily) and Wegovy is semaglutide (weekly), with Wegovy producing more weight loss.
The practical difference
Wegovy's weekly dosing and greater efficacy have made it the preferred choice over daily Saxenda for most. Saxenda remains an option, especially where semaglutide is unavailable.
When to check with your doctor
This is general information, not a prescription. Your dose, your other medicines and your medical history all change the picture — message your ZIVOLABS doctor before making any change to how you take your medication.
The science, in plain language
Think of {b} as topping up a hunger-control signal your body already makes but doesn't make enough of. By acting on appetite centres in the brain and slowing digestion, it shrinks portion sizes and cravings without you having to count every calorie. Because it nudges insulin only when blood sugar is high, it also steadies glucose — which is why this class of drug came from diabetes care before it was widely used for weight. It is not a stimulant and not a 'fat burner'; it changes appetite, and the weight loss follows from eating less.
Your likely month-by-month journey
-
Month 1 is about tolerance, not the scale — you titrate up slowly so your gut adapts and side effects stay mild.
-
Month 2 is when most people notice clothes fitting looser and portions feeling smaller without effort.
-
Month 3 is the first real checkpoint: if you've lost under 3% of your weight, your doctor reviews the dose or molecule.
-
Months 4–6 deliver the bulk of the visible change, especially around the waist as visceral fat responds first.
-
After 6 months, the focus moves from losing to maintaining — a lower steady dose plus the habits you've built.
Side effects and how to manage them
-
Nausea is the most common, mostly in week one and after each dose increase. Smaller portions, less oily food, ginger or jeera water, and staying upright after eating all help.
-
Constipation responds to three litres of water a day, daily isabgol (psyllium husk), fruit and sprouts, and a short walk after meals.
-
Fatigue usually means you're eating too little — check your protein, iron and B12, and don't cut calories too hard.
-
Reflux eases with lighter, earlier dinners and not lying down after eating; a short course of antacids or a PPI helps if needed.
-
Most side effects are temporary and fade as your body adjusts. Anything severe or persistent — especially intense upper-abdominal pain — should go straight to your doctor.
Who's a good candidate — and who isn't
GLP-1 weight treatment is generally for adults with a BMI of 30 or above, or 27 and above with a weight-related condition such as type 2 diabetes, PCOS, fatty liver, high blood pressure or sleep apnoea. It isn't suitable for everyone: it's avoided in pregnancy and breastfeeding, and ruled out entirely for people with a personal or family history of medullary thyroid cancer or MEN-2 syndrome. A past episode of pancreatitis or a history of eating disorders calls for extra caution. This is exactly why a proper medical assessment comes first — a doctor will tell you honestly whether it's right for you, including when the answer is no.
What it costs in India
As a rough guide, expect ₹16,000–₹26,000 a month, varying by dose, brand and pharmacy, with 12% GST already built into the MRP. Costs are usually highest during the dose-escalation months and lower once you settle onto a maintenance dose. Health insurance in India typically covers GLP-1 only when it's prescribed for diabetes, not for weight loss alone, though many corporate packages include a medical-reimbursement allowance you can use. The cheapest 'option' — an unverified pen from an unlicensed seller — is the one that actually costs the most if it's fake.
Staying safe: genuine medication only
Counterfeit and grey-market GLP-1 is a real and growing problem across India, often sold cheaply on messaging apps and unverified websites. Fake pens can be unsterile, wrongly dosed, or contain nothing useful at all — and there have been confirmed harms in India. Protect yourself: buy only from a CDSCO-licensed pharmacy against a valid prescription, check the hologram, batch number and expiry, and treat any price far below the market rate as a warning sign. A genuine pen always comes with a traceable invoice and the dispensing pharmacist's details.
Frequently asked questions
Will I regain the weight if I stop?
Often, yes — appetite returns once the medicine clears, so a planned step-down to a maintenance dose plus the habits you've built is far better than stopping abruptly.
Do I need to follow a strict diet?
No strict diet, but protein matters: aim for 1.2–1.6 g per kg of body weight a day to protect muscle, and keep fried food and refined carbs modest to avoid nausea.
Is it safe to take long-term?
The evidence to date is reassuring across multi-year trials, including cardiovascular benefit. It's intended for long-term use under medical supervision.
Can I take it if I'm not diabetic?
Yes — GLP-1 medicines are approved for weight management in people without diabetes who meet the BMI criteria, and are used that way safely worldwide.
How ZIVOLABS supports you through it
ZIVOLABS is built as a doctor-supervised GLP-1 program for India, not just a pharmacy. You start with a proper medical assessment online; a verified doctor reviews your history, confirms whether treatment is appropriate, and writes a genuine prescription if so. Your medication is dispensed by a CDSCO-licensed pharmacy and delivered cold-chain to your door, and you can message your care team whenever side effects or questions come up. Dose changes, plateaus and the eventual step-down to maintenance are all guided — because the medicine works best with a plan and a clinician around it.
Key takeaways
-
Wegovy (semaglutide) reduces appetite and slows digestion, so you eat less without constant hunger.
-
Protein (1.2–1.6 g/kg/day) plus two to three strength sessions a week protect muscle while you lose fat.
-
Side effects are mostly early and manageable; start low, go slow, and report anything severe.
-
Buy only genuine, doctor-prescribed medication from a licensed pharmacy — counterfeits are a real risk in India.
-
It works best as a supervised plan, with a maintenance dose to hold the result rather than stopping abruptly.
