Wegovy Pill vs Injection: Which Works Better and Which Should You Choose?

Written by Diana Gangan. Updated October 22, 2026.

The Wegovy pill and the Wegovy injection contain the same drug, semaglutide, and work almost as well as each other. In their main trials, people lost about 13.6% of their body weight on the 25 mg daily pill over 64 weeks and about 15% on the 2.4 mg weekly injection over 68 weeks. The real differences are routine and price: the pill is taken every morning on an empty stomach and starts at $149 a month self-pay; the injection is once a week, any time of day, and costs $199 to $349, with a stronger 7.2 mg HD option.

Here's a side-by-side comparison to help you and your prescriber choose.

Nearly. The 25 mg pill produced about 13.6% average weight loss in OASIS 4, compared with about 15% for the injection in STEP 1. The trials were separate, with different lengths and populations, so the 1 to 2 point gap is approximate. Both are far ahead of older weight-loss drugs.

The bigger practical difference is absorption. Semaglutide is a peptide, and very little of it gets through the stomach. The pill only works well when you follow the routine exactly: swallow it first thing in the morning with no more than half a cup of plain water, then wait at least 30 minutes before eating, drinking anything else or taking other medicines. Taking it with coffee or breakfast can cut absorption sharply, and that's the most common reason the pill seems not to work.

Same molecule, same side effects: nausea, diarrhea, vomiting and constipation, mostly during the first weeks and after each dose increase. Both forms escalate slowly to limit them. If you're sensitive to the early weeks, the injection's lowest dose (0.25 mg) and the pill's lowest dose (1.5 mg) are both designed as starter steps, not treatment doses. See our side-effects guide.

Self-pay through Novo Nordisk: the pill costs $149 for 1.5 mg, $199 for 4 mg and $299 for 9 mg and 25 mg; the pen costs $199 for the first two fills of starter doses (through 2026) and $349 after, with HD at $399. With commercial insurance that covers Wegovy, the savings card can bring either to as little as $25. Medicare's GLP-1 Bridge covers both forms for $50 a month. Details in our Wegovy cost guide.

Yes, with your prescriber. The doses don't convert milligram for milligram because so little of the pill is absorbed, so your prescriber will pick the starting dose. See our Wegovy dosing schedule for both ladders.

The Wegovy pill and injection are close in effectiveness: about 13.6% versus 15% average weight loss. Choose the pill if you want to avoid needles and can keep a strict morning routine; choose the injection if you prefer once a week, want the HD option, or find fasting mornings hard. Price differences are small. For all the options, including Zepbound and Foundayo, see which GLP-1 is best.
