Semaglutide amounts rose slowly to limit stomach trouble.

Your doctor checks your health before prescribing Semaglutide

This page reports how semaglutide was dosed in the trials and in its approved labeling. It is a record, not a recommendation: dosing is something a prescriber decides for an individual, and nothing here tells you what to take.

The pattern across studies is a slow build-up. The once-weekly injection starts low and steps up over weeks — this gradual increase is the main tool for limiting the stomach upset that comes with the drug. The daily pill (oral semaglutide) has its own schedule and a strict rule: take it on an empty stomach with only a little water. The drug lasts about a week in the body, which is why one injection covers a whole week and why it takes roughly five weeks to clear after the last dose ^[11]. Every figure below is tied to a trial protocol or the label.

Every dose described above is available only by prescription in the United States, and writing that prescription is a clinical process rather than a single transaction. It typically opens with an intake: current health status, a review of past and present conditions, and a full medication list, so that anything relevant to a GLP-1 receptor agonist — a personal or family history of medullary thyroid cancer, prior pancreatitis, or a planned pregnancy — surfaces before a dose is set rather than after. Screening for those contraindications is what turns the escalation schedule above into a decision rather than a default: a clinician chooses the starting dose, the pace of increase, and whether to pause or hold at a given step, based on how the patient tolerates each stage. Promise Peptides (mypromise.com), a licensed telehealth provider, prescribes semaglutide within that same structure: its clinicians evaluate the intake before writing anything and retain the standing option to decline to prescribe, or to change course if the history or the response does not support continuing. Follow-up after each titration step, and a channel to report side effects, are part of the same oversight rather than an afterthought. None of that process is incidental to the medicine; it is the mechanism by which a prescription-only drug stays matched to the person taking it — the distinction between being prescribed semaglutide and simply acquiring it.

Semaglutide dose changes were small and slow

For long-term weight care, the weekly shot began at 0.25 mg. That amount stayed through weeks 1-4.

The next study amounts were 0.5 mg, 1.0 mg, and 1.7 mg. The long-term amount was 2.4 mg once a week.

STEP 1 used this slow climb ^[1]. STEP 4 and the two-year STEP 5 study used it too ^[9].

The heart and liver studies used the same steps ^[3][12]. Going slowly aimed to ease stomach trouble.

A review found most stomach problems were mild and short ^[13]. They happened most often while the amount rose.

For type 2 diabetes, the shot also began at 0.25 mg weekly. The next amount was 0.5 mg.

A common long-term amount was 1.0 mg. SUSTAIN-6 used either 0.5 mg or 1.0 mg ^[2].

The kidney study used 1.0 mg ^[6]. These figures don’t account for your health, other pills, side effects, or how you felt at each step.

Semaglutide dosage for weight loss rose before the final result

The main weight studies worked up to 2.4 mg each week. It wasn’t a pill; researchers gave it under the skin.

At 68 weeks, STEP 1 found 14.9% average weight loss ^[1]. STEP 5 found that loss held for two years ^[8].

STEP UP tested a higher 7.2 mg weekly amount. It was still being tested and wasn’t approved.

These numbers tell you what researchers tested. They don’t set your dose.

A study can’t account for your full health. Your doctor has to make that call.

The Semaglutide injection is a shot under your skin

The Semaglutide injection is one dose under your skin each week. It’s given on the same weekday.

DPP-4 is a body chemical that normally breaks down the gut hormone. The shot is made so that body chemical can’t break it down quickly, letting the medicine last roughly a week ^[11].

A weight study found people lost both fat and muscle ^[16]. Muscle matters for balance and strength as you age.

Researchers are testing enough protein in meals and strength exercises with the shot. Patients also report brief redness, itching, or a small bump.

Those skin reports appear on Semaglutide effects. A skin study didn’t test those reports.

The shot won’t protect muscle by itself. Ask your doctor how your strength can be watched.

Oral Semaglutide works only when the stomach rules are followed

Oral Semaglutide is a pill taken each day. An added ingredient helps some medicine cross the stomach lining ^[22].

The diabetes study began with 3 mg daily for 30 days. The next amounts were 7 mg and 14 mg daily.

People in the study took the pill about 30 minutes before food, drinks, or another medicine, using at most half a cup of water, about 120 mL each day ^[22].

Two other studies tested daily pills of 25 mg and 50 mg. Those higher amounts were studied in people with obesity.

Only about 0.4-1% of a swallowed dose reaches the blood. It’s made to work with that small share ^[22].

Food or too much water can cut the share further. That’s why an empty stomach matters.

These are study facts, not your directions. The instructions with your pills tell you what to do.

Semaglutide remains in your body for about five weeks

Your body removes half of Semaglutide in about one week ^[11]. The shot and pill leave at about the same pace.

After roughly five weeks, most of the drug is gone. That’s why the effects don’t stop at once.

Semaglutide resists DPP-4, a body chemical that normally breaks the gut hormone down. That’s why a weekly shot keeps working.

Before pregnancy, the label requires an early stop ^[21]. Ask your doctor how long that required wait is.

Unopened pens are kept in the refrigerator. Your pen’s label says how long it may stay at room temperature after first use.

Storage time differs by pen, so read that exact label. This page isn’t your handling guide.

The timing won’t be exact for everyone. It can help your doctor judge how long medicine may remain.
