Wegovy 7.2 mg: Who Should Consider the Higher Dose?

On By Dr. Scott RennieIn Weight Loss & Metabolic HealthLeave a comment

Wegovy just got a new top rung on the ladder. In March of this year, the FDA approved a higher, 7.2 mg dose of semaglutide, marketed as Wegovy HD, for adults with obesity or overweight. This is a new ceiling on a drug we already know well. Same drug. Higher rung. I think it’s worth walking through what the data actually shows before deciding who in your practice, or mine, is a good candidate for it.

The approval leaned on two trials, STEP UP and STEP UP T2D, both 72-week phase 3 studies. In STEP UP, which enrolled adults with obesity but without type 2 diabetes, patients on 7.2 mg lost an average of 20.7% of body weight, compared with 15.6% on the standard 2.4 mg dose and 3.9% on placebo, a meaningful jump and not a marginal one. Almost a third of patients on the higher dose, 31.2%, lost a quarter or more of their starting body weight. In the companion trial, STEP UP T2D, which looked at patients with obesity and type 2 diabetes, the numbers were lower but still substantial: 14.1% average weight loss, with about a fifth of patients losing 20% or more. That gap between the diabetes and non-diabetes cohorts isn’t surprising. We see it consistently with GLP-1 therapy, and it’s a good reminder to set expectations differently for patients with T2D up front.

Here’s the part that matters most for how I’ll actually use this in practice: Wegovy HD isn’t a starting dose. The label requires that a patient have already tolerated 2.4 mg for at least four weeks before stepping up, and the escalation is meant for patients where additional weight loss is clinically indicated, meaning the 2.4 mg dose hasn’t gotten them where they need to be. So the ideal candidate is someone who’s already on semaglutide, tolerating it reasonably well, but has plateaued short of their goal or still has a lot of excess weight to lose relative to their comorbidities. Think of a patient who’s been on 2.4 mg for six months, lost maybe 10-12% of body weight, tolerates the GI side effects fine, but still has a BMI well into obesity range with sleep apnea or hypertension that hasn’t fully responded. That’s the kind of case where I’d bring up 7.2 mg. It’s not for someone just starting therapy, and it’s not for someone who’s struggling with nausea or GI symptoms at the lower dose. If they can’t tolerate 2.4 mg, going higher solves nothing.

Which brings up the safety side, because the tradeoff here is real.

Overall tolerability at the higher dose was described as similar to what’s been seen with 2.4 mg, with GI effects like nausea, vomiting, constipation, and abdominal pain remaining the most common complaints. But two numbers stood out to me. Dysesthesia, essentially altered or abnormal skin sensation, occurred in 22% of patients on 7.2 mg versus 6% on 2.4 mg and 0.3% on placebo. That’s not a side effect I’d been counting on discussing much with patients on standard-dose semaglutide, and it’s one I’ll need to specifically ask about at follow-up visits once patients move up. I’ve seen the same pattern in my own patients, the ones who dose escalate quickly on standard Wegovy dosing, well before anyone gets near 7.2 mg. The trial data and my own visit notes agree on that one. Dose reductions due to adverse events were also more common at the higher dose, 18.5% versus 12.4% on 2.4 mg, and discontinuation due to side effects ran around 5.4%. The higher dose isn’t a free upgrade. You’re trading tolerability for more weight loss, and that’s a conversation to have explicitly with the patient rather than assume they’d automatically want the escalation.

From a practical standpoint, Wegovy HD is expected to be available through pharmacies and telehealth channels starting in April, delivered in a single-dose pen. I don’t think this changes how I approach a new patient starting on semaglutide at all, the same titration principles from 2.4 mg still apply. What it does is give me another option for the subset of patients who’ve done well but not well enough, and who’ve shown they can handle the medication without major GI intolerance. That’s a narrower group than “everyone on Wegovy,” and I’d resist the urge, mine or a patient’s, to jump to the higher dose just because it’s now available. The data supports it for the right patient. It doesn’t support treating it as the new default starting point.

Foundayo vs. the Wegovy Pill: Comparing the Two New Weight Loss Pills

On By Dr. Scott RennieIn Weight Loss & Metabolic HealthLeave a comment

For years, if you asked me “is there a pill version of these weight-loss drugs?”, the honest answer was no, not really. That changed twice, four months apart. If you haven’t been following closely, the options today look nothing like they did two years ago.

A quick note on names first, since patients ask me this a lot. The Lilly drug some people have heard called “Fonday-o” is orforglipron. The FDA approved it on April 1, 2026, under the brand name Foundayo (1). Before that, on December 22, 2025, the FDA approved a 25 mg oral semaglutide tablet under the Wegovy name (2). GLP-1 medicines help control appetite and blood sugar, and that tablet was the first pill version of one approved for long-term weight management. Both are real, both are approved, and both can be prescribed today.

Both full prescribing labels are now public, and they differ in ways that decide the choice for a lot of people. Most of those differences have nothing to do with how much weight each one takes off.

Why the two pills work so differently in your body

Semaglutide is a peptide, which is a small chain of amino acids, the building blocks of proteins. Your stomach is very good at breaking down peptides, which is exactly why semaglutide originally had to be given as a shot.

Novo Nordisk’s solution was to add an ingredient called SNAC that helps the drug get absorbed before your stomach destroys it. According to a review in the journal Clinical Diabetes, SNAC does three things at once (3). It changes the local acidity around the tablet as it dissolves, it briefly protects the drug from a stomach enzyme called pepsin, and it helps the drug cross the stomach lining into your bloodstream. The absorption happens in the stomach itself rather than the intestines, which is unusual for a pill. The drug essentially enters your body right where the tablet is sitting against your stomach wall.

That trick comes with a catch, and the label is specific about it (4). You take the tablet on an empty stomach in the morning with no more than four ounces of plain water. No other liquids. Swallow it whole, and wait at least 30 minutes before you eat, drink anything, or take any other oral medication.

Thirty minutes. Every morning. Before coffee.

Orforglipron works completely differently. It is a small molecule, meaning a stable chemical rather than a fragile peptide chain. It belongs to the same drug family, mimicking a natural gut hormone that reduces appetite, but with no peptide to protect it needs no absorption booster and carries no timing ritual. Its label says to take it once daily with or without food, and specifies no water restriction and no waiting period (5). For someone who works nights, or who already swallows six other pills at breakfast, that is the whole ballgame.

What the labels actually say, and why the number in your news feed is wrong

Most of the figures circulating online come from journal publications and press releases rather than from the approved labels. The label numbers are the ones your prescription is based on, so those are the ones I use.

For Wegovy tablets, the label reports a 64-week trial in 205 adults on the tablet against 102 on placebo, all with obesity or overweight plus a weight-related condition, with diabetes excluded (4). Average weight change was 13.6 percent down on the tablet and 2.4 percent down on placebo, a difference of 11.2 percentage points. Broken out by how much people lost: 76.3 percent lost at least 5 percent of their body weight versus 31.3 percent on placebo, 59.8 percent lost at least 10 percent versus 14.4 percent, 47 percent lost at least 15 percent versus 5.5 percent, and 27.9 percent lost at least 20 percent versus 3.1 percent.

For Foundayo, the label reports a 72-week trial in 3,127 adults without diabetes (5). Average weight change was 7.4 percent down at the 5.5 mg dose, 8.3 percent down at 9 mg, and 11.1 percent down at the maximum 17.2 mg dose, against 2.1 percent down on placebo. At 17.2 mg, 35.9 percent of patients lost at least 15 percent of their body weight, compared with 6 percent on placebo.

Put those side by side and the semaglutide tablet looks better, and I would be careful with that read. Different patients, different trial lengths, different placebo responses, and nobody randomized the same people to both. What is harder to wave away is the size of each evidence base. The semaglutide tablet’s label efficacy rests on 205 treated patients. Foundayo’s rests on 3,127. Both cleared the FDA, so both met the bar, but I have more confidence in how a drug behaves across a wide range of real people when the number in the trial is measured in thousands.

Here is the detail that confuses almost everyone who reads the news coverage. The approved Foundayo strengths are 0.8, 2.5, 5.5, 9, 14.5, and 17.2 mg, stepped up roughly every 30 days. The trial used a capsule at 1, 3, 6, 12, 24, and 36 mg. Those map onto each other in order, so the 17.2 mg tablet you can actually be prescribed is the 36 mg dose you read about. If your maximum dose sounds far smaller than the headline, that is why.

One thing I noticed reading the Foundayo label closely: the 14.5 mg strength is approved and dispensable, and it does not appear in the label’s efficacy table at all. You can be prescribed a dose with no published average weight loss attached to it. Not dangerous, just worth knowing if you end up parked there.

The only comparison anyone has run, and who paid for it

There is still no head-to-head trial of these two drugs in obesity. There is now an indirect comparison, published in Diabetes, Obesity and Metabolism in August 2026, which pulled individual patient data from the semaglutide tablet trial and aggregate data from the orforglipron trial and statistically adjusted for differences in sex, body weight and glucose status between the two populations (6).

It found oral semaglutide 25 mg ahead by 3.2 percentage points of body weight (95% confidence interval 5.9 to 0.4) and reported higher discontinuation with orforglipron, with an odds ratio of 4.1 for stopping due to any adverse event and 13.9 for stopping due to gastrointestinal side effects.

Five of the authors are Novo Nordisk employees and shareholders, two more work for a consultancy Novo paid to run the analysis, and Novo makes the drug that won. That does not make the result false. It does mean I apply a discount. The direction is plausible and roughly matches the gap between the two labels. The magnitude I would not quote to a patient as fact. And that gastrointestinal odds ratio of 13.9 has a confidence interval running from 2.0 to 96.0, which is another way of saying the study could not pin it down.

There is one true head-to-head, and it points the other way. In adults with type 2 diabetes, orforglipron beat oral semaglutide on weight loss (7). That trial used semaglutide at 7 mg and 14 mg, well under the 25 mg weight-management dose, in a different population, for a different purpose. It answers a different question than the one you are asking.

Birth control is the difference nobody mentions

This is the most actionable difference between the two drugs and it almost never comes up in the coverage.

The Foundayo label instructs patients on oral hormonal contraceptives to switch to a non-oral method, or to add a barrier method for 30 days after starting the drug and for 30 days after every dose escalation (5). Count the escalations. With six strengths, somebody climbing to the top dose is looking at several separate 30-day windows where their pill alone is not considered reliable. Non-oral hormonal contraception is not expected to be affected.

The Wegovy tablet label carries no equivalent instruction. Its pharmacokinetic studies found no clinically significant interaction with ethinyl estradiol and levonorgestrel (4).

For a woman in her twenties or thirties on a combined oral contraceptive who does not want a pregnancy, that single difference outweighs three percentage points of average weight loss. I bring it up before either drug gets prescribed, not after.

The other interactions that quietly decide this

Orforglipron is cleared through CYP3A4, and the label puts real fences around that (5). On a strong CYP3A4 inhibitor, the maximum Foundayo dose drops to 9 mg. Clarithromycin raised orforglipron exposure 3.5-fold in a study. Going the other way, carbamazepine cut exposure by 82 percent and efavirenz by 61 percent, so strong inducers are to be avoided and moderate ones need the dose pushed up while you watch whether it still works. Strong inhibitors that also block OATP1B, ritonavir being the example the label gives, are to be avoided outright. And simvastatin is capped at 20 mg a day alongside it.

The semaglutide tablet has a shorter list but one that matters in my practice. A single 600 mcg dose of levothyroxine taken with it produced a 33 percent rise in total thyroxine exposure (4). Add the 30-minute rule on top, which pushes every other morning medication back, and a patient on thyroid replacement plus a few other dailies has a genuine scheduling problem.

If someone comes to me on carbamazepine, or on ritonavir-boosted therapy, Foundayo is awkward enough that I start elsewhere. If someone is on levothyroxine and already struggles to take it correctly, I think hard before adding a second pill with its own empty-stomach window.

Side effects

Both drugs hit the gut, and both labels say so plainly.

Foundayo’s pooled safety data runs nausea at 26 percent, 34 percent and 35 percent across the 5.5, 9 and 17.2 mg doses against 10 percent on placebo (5). Vomiting climbs from 13 to 24 percent against 4 percent. Constipation runs 20 to 27 percent against 9 percent, and diarrhea 21 to 25 percent against 11 percent. Hair loss shows up at 4 to 5 percent against 2 percent, which patients ask me about more than the numbers would suggest.

The Wegovy tablet label describes side effects similar to the injection, and adds a few tablet-specific figures (4). Just under 7 percent of patients stopped the drug for an adverse reaction, against about 6 percent on placebo. Severe gastrointestinal reactions occurred in 2 percent of tablet patients and no placebo patients. Dysesthesia, meaning abnormal or unpleasant sensation, was reported in 5 percent of tablet patients and in nobody on placebo. That last one is not something I had on my radar before reading the label, and it is worth mentioning to a patient who calls about odd skin sensations rather than writing it off.

Both drugs carry a boxed warning about thyroid C-cell tumors and are contraindicated in anyone with a personal or family history of medullary thyroid carcinoma or MEN 2 (4)(5).

If you have heart disease, the answer is already made

Wegovy tablets carry an approved indication to reduce the risk of major adverse cardiovascular events, meaning cardiovascular death, non-fatal heart attack and non-fatal stroke, in adults with established cardiovascular disease and either obesity or overweight (4). The wording is identical to the injection’s.

Foundayo has no cardiovascular outcome indication. Its cardiovascular outcomes trial has not reported.

For a patient who has already had a heart attack or a stroke, that settles it. I go to semaglutide, and the only remaining question is tablet or injection.

How I actually choose

If you are the patient reading this, the useful question is not which drug is stronger. It is which one you will still be taking in a year. The 30-minute waiting period for the semaglutide tablet sounds minor when we talk it through on a video visit, and it trips people up in real life. I have watched patients lose ground on oral semaglutide because weekday mornings made the timing rules impossible to follow, and the drug cannot work from inside the bottle. If your mornings are chaotic, say so out loud when we talk. That is clinical information, not an excuse.

If you are a prescriber, I would frame the choice around four things before efficacy. Established cardiovascular disease points to semaglutide on the label. An oral contraceptive points away from orforglipron, or at least commits you to counseling a barrier method through every escalation. A CYP3A4 problem, especially an enzyme inducer, makes orforglipron hard to dose. Levothyroxine and a crowded morning pill box make the semaglutide tablet hard to take. What is left after those four filters is usually a clear answer, and in my experience the efficacy gap is the least useful thing to lead with.

What this costs right now

Both manufacturers run tiered self-pay pricing that starts low at the smallest dose and rises as you titrate up, and both have promotional rates on their lower strengths that are scheduled to end on December 31, 2026. Because these terms change faster than I can keep a blog post current, check the two official pages directly rather than trusting a number you read anywhere, including here: LillyDirect for Foundayo (8) and NovoCare for Wegovy (9).

What I can tell you from prescribing both is operational. I haven’t run into a prior-authorization fight or a stocking problem with Foundayo yet. Most of what I prescribe goes through LillyDirect on cash pay, because it has been one of the cheaper options on the table. Patients who have real insurance coverage tend to ask for injectable Wegovy or Zepbound instead, and I do not talk them out of it. For a fuller breakdown of cash prices across the whole class, including the injections, see my separate post on cash pay options.

The Bottom Line

Two pills, both approved, both effective, and the deciding factors are mostly not about weight loss. The semaglutide tablet takes off a bit more weight in the label data, carries a cardiovascular indication, and demands an empty stomach and a 30-minute wait every single morning. Foundayo asks nothing of your schedule, has a far larger trial behind it, and brings a contraception instruction and a list of drug interactions that rule it out for some people entirely.

Bring your actual medication list and your actual morning routine to the visit. Those two things will pick the drug faster than any comparison chart.

Can You Do Intermittent Fasting on Ozempic or Wegovy?

On By Dr. Scott RennieIn Weight Loss & Metabolic HealthLeave a comment

Weight comes up in almost every visit I do. For some patients it is fifteen pounds standing between them and a better blood pressure number. For others it is obesity that has already done damage, and the conversation starts further back. The work can feel overwhelming from the inside. What’s changed is that the tools finally match the size of the problem. Medications like Ozempic, Wegovy, Mounjaro, and Zepbound, the GLP-1 receptor agonists, have shifted how this is approached, and paired with a structure like intermittent fasting they help people lose weight and keep it off.

What GLP-1 Agonists Do

These drugs mimic glucagon-like peptide-1, a hormone that regulates appetite and blood sugar. Given as medication, they slow gastric emptying and push stronger satiety signals to the brain, so fullness arrives earlier and stays longer. They also improve insulin sensitivity, which is why they earned their place in type 2 diabetes first.

The weight effect is substantial. Wegovy and Zepbound carry FDA approval specifically for weight loss. Ozempic and Mounjaro are approved for diabetes and produce strong weight results as well, which is the source of most of the confusion patients arrive with about which drug is which.

How They Work With Intermittent Fasting

Intermittent fasting improves insulin sensitivity, supports fat loss, and helps regulate hunger hormones. Staying with it is the hard part. Many patients tell me they can’t get past the hunger. GLP-1 medications change that equation by blunting appetite and cravings, which makes a fasting schedule something a person can actually hold.

A patient of mine started a 16:8 fasting plan (16 hours fasting, 8 hours eating) while on a GLP-1 medication. Before starting the medication, she felt shaky and irritable during fasting. After starting, she was surprised by how manageable it felt. She ate smaller meals, felt full, and didn’t struggle to maintain the fasting window.

Side Effects and Adjustments

Nausea leads the list, and it’s worst early. Diarrhea and reflux show up too. Most of it settles as the body adapts. Start low, titrate slowly, and resist the urge to chase the next dose because the scale stalled for two weeks. Patients who stay in contact through the titration get their dose adjusted before they quit over side effects, and the ones who go quiet are the ones who stop the drug entirely.

Barriers to Access

Getting these medications is its own project. Cost is the main wall. Insurance coverage for weight loss remains inconsistent in a way that’s hard to explain to a patient who has just been told the drug would help, and out-of-pocket pricing is punishing. Demand has outrun supply, so delays and shortages are part of the picture.

Then there are the compounded versions. Some pharmacies sell them well below brand pricing, and they’re not FDA-approved. Safety and potency can’t be guaranteed. I tell patients to stay away from them, and I don’t soften that advice when someone pushes back on price.

Putting It Into Context

These aren’t quick fixes. They are tools, and they work when they sit on top of durable changes: balanced eating, regular activity, attention to mental health. Intermittent fasting is one workable way to structure eating alongside them. The lifestyle piece doesn’t become optional because a medication is doing part of the lifting.

When patients pair the medication with habits they can sustain, results hold longer and vary less. The goal is a set of strategies that still works three years from now, not the fastest possible drop on the scale.
