You started Wegovy (the brand name for a medication containing semaglutide) this week and expected to feel something within a few days, but so far you’ve noticed nothing and are worried you might have injected it wrong or wasted the dose because there was a drop on the pen when you opened it. Semaglutide is the active drug in Wegovy. It’s a man-made copy of a natural hormone that helps control appetite and blood sugar. In simple terms, it tells parts of your brain you’re less hungry and it slows how fast food leaves your stomach. It isn’t an immediate stimulant; it works gradually by changing signals in your body over weeks and months. The clinical evidence and real-world experience show that most meaningful effects on appetite and weight take time. When people start semaglutide, the dose is usually low and then slowly increased over several weeks to reduce side effects. Early side effects—nausea, stomach upset, or feeling full—can show up in the first days for some people, but many don’t feel obvious changes right away. The big changes in appetite and weight are usually seen after several weeks to months at an effective dose, not within the first 48–72 hours. Also, single-user anecdotes vary a lot; some folks report immediate mild effects while others feel nothing for longer. Practical takeaway: if you’re in your first week and on a low starting dose, it’s normal not to notice much yet. Check the dosing schedule your prescriber gave you and keep follow-up appointments. If you’re concerned you might have injected incorrectly, it’s fine to ask your pharmacy or clinic to review your injection technique—many places will demonstrate or confirm how to use the pen. If you lost part of a dose or think the pen leaked, contact the pharmacy or manufacturer for guidance about whether that dose should be replaced. Caveats and risks: Wegovy is a prescription medicine with known side effects—most commonly nausea, vomiting, constipation, diarrhea, and stomach pain. Serious but rare risks include pancreatitis (inflammation of the pancreas) and possible effects on the gallbladder. Don’t restart or change doses on your own. If you have a history of certain conditions (like thyroid cancer in your family, severe gastrointestinal disease, or pancreatitis), discuss that with your doctor because semaglutide may not be suitable. If you suspect the pen is defective, or if you have symptoms of a severe reaction, contact your provider or emergency services. Bottom line: not feeling anything in the first few days is common and doesn’t necessarily mean the injection failed—give it time, confirm your dosing plan and technique with your healthcare team, and report any worrying symptoms or suspected equipment problems.
