Wegovy is an injection, not a pill. It comes as a pre-filled pen that you inject under the skin once per week. The active ingredient in Wegovy, semaglutide, does exist in pill form under a different brand name (Rybelsus), but Wegovy itself is only available as an injectable.
How the Injection Works
Wegovy is delivered through a pre-filled, single-use pen. Each pen contains one dose, and you use it once then throw it away. The needle is hidden inside the pen before, during, and after use, so you never actually see it. Dosing is automatic: you press the pen against your skin and it delivers the medication on its own.
You inject Wegovy into one of three body areas: the lower stomach (at least 2 inches from your belly button), the front of your upper thigh, or your upper arm. The stomach tends to be the easiest spot to reach on your own. The thigh works well if you prefer sitting down, since the firmer surface gives you more control. The upper arm is a good rotation option but can be hard to reach without help from someone else.
You should rotate the exact spot where the needle enters each week, even if you stick with the same general area. This reduces the risk of skin irritation or hard lumps forming. Always choose a patch of skin that’s free of scars, stretch marks, bruises, or redness.
Dosing Schedule
Wegovy is taken once a week, on the same day each week, at any time of day, with or without food. You don’t need to build it around meals.
The dose increases gradually over the first four months to help your body adjust and reduce side effects, particularly nausea. The schedule looks like this:
- Weeks 1 through 4: 0.25 mg
- Weeks 5 through 8: 0.5 mg
- Weeks 9 through 12: 1 mg
- Weeks 13 through 16: 1.7 mg
- Week 17 onward: 2.4 mg (maintenance dose)
If you have trouble tolerating a dose increase, your prescriber may keep you at the current dose for an extra four weeks before moving up. Some people stay at the 1.7 mg dose long-term if 2.4 mg causes too many side effects.
Injection Site Reactions
In clinical trials, about 1.4% of people using Wegovy reported reactions at the injection site, compared to 1% on placebo. These reactions included redness, itching, inflammation, and irritation. In other words, injection site problems are uncommon and typically mild when they do occur.
What About a Semaglutide Pill?
Semaglutide already exists in tablet form as Rybelsus, which is approved for type 2 diabetes. However, Rybelsus comes in lower doses than Wegovy and is taken daily rather than weekly. It also has strict dosing rules: you take it first thing in the morning on an empty stomach with only a sip of water, then wait at least 30 minutes before eating, drinking, or taking other medications.
A higher-dose oral semaglutide tablet (50 mg) has been tested specifically for weight loss. In a phase 3 trial of 667 adults with obesity, the pill produced an average weight loss of 15.1% over 68 weeks, compared to 2.4% with placebo. About 85% of participants on the pill lost at least 5% of their body weight, and roughly one in three lost 20% or more. Gastrointestinal side effects (mostly mild to moderate nausea and related symptoms) were reported by 80% of participants on the pill versus 46% on placebo. This higher-dose oral version has not yet been approved as a weight loss medication.
Storing the Pens
Wegovy pens need to be refrigerated between 36°F and 46°F (2°C to 8°C), ideally in their original carton. If you need to carry a pen with you or don’t have fridge access, it can stay at room temperature (up to 86°F) for up to 28 days before you remove the cap. Throw the pen away if it has been frozen, left above 86°F, exposed to direct light, or kept out of the refrigerator for longer than 28 days.
