Quick Answer
Most Ozempic and Wegovy poisoning calls are caused by two preventable mistakes: taking it daily instead of weekly, and starting at the maximum dose. Know the correct schedule before you inject.

If you or someone in your family has recently started Ozempic, Wegovy, or a generic semaglutide injection in India, there is a critical piece of information you need to know — and it is not about side effects or cost. A new study published in the Journal of Medical Toxicology has revealed that the most common reason people end up in medical emergencies with these drugs is a simple dosing misunderstanding: they take the injection every day instead of every week, or they start immediately at the highest dose instead of following the required step-up schedule. In the United States, this mistake caused poison control calls for semaglutide to jump from around 1,000 to 1,500 cases per year to more than 8,000 cases in 2023 — an increase of over five times. As GLP-1 use grows rapidly in India, doctors and pharmacists here are raising the same concern.
What the New Research Found
Researchers at the University of Texas at San Antonio analyzed national poison control data spanning the period before and after the US FDA approved semaglutide for chronic weight management in 2021. The study, which was also featured as the cover story in Significance — the flagship journal of the Royal Statistical Society — found a dramatic and direct link between the expansion of GLP-1 use for weight loss and the spike in adverse events.
Before semaglutide was widely used for weight loss, poison control centers handled mostly cases from people with type 2 diabetes who were already familiar with injectable medications. After approval for weight management, an entirely new group of patients — people without diabetes, many injecting themselves at home for the first time — began using the drug. Many of them made the same two mistakes.
Mistake one: taking the injection daily instead of weekly. Semaglutide injections like Ozempic and Wegovy are designed to be given once every seven days — not once a day. A patient who injects seven days in a row effectively takes seven times the intended dose in a single week. The result can be severe nausea, vomiting, dangerously low blood sugar if the patient is also on other diabetes medication, and in some cases dehydration requiring hospital admission.
Mistake two: starting at the maximum dose. Ozempic is prescribed on a titration schedule: patients typically begin at 0.25 mg per week for four weeks, then move to 0.5 mg, and only step up further if well tolerated. Patients who start immediately at 1 mg or 2 mg — perhaps because they want faster results — expose themselves to a much higher rate of side effects than patients who follow the approved schedule.

Why This Matters Especially in India
In India, GLP-1 use is growing fast. Since generic semaglutide injections became available from manufacturers including Natco Pharma, Sun Pharma, and Cipla in early 2026, prices have dropped to as low as Rs 1,290 per month, bringing these drugs within reach of a far larger population. Many patients in India are starting GLP-1 injections with minimal supervision — buying online, or receiving a short prescription without a detailed injection counselling session.
This mirrors exactly the pattern the US researchers identified as the root cause of the poison control surge: rapid expansion of use to patients who had never injected themselves before and who did not fully understand the weekly dosing schedule or the titration requirement.
The situation is compounded by the fact that semaglutide pens can look similar to daily insulin pens that many Indian patients or their family members are already familiar with. A person who has previously used insulin — which is injected daily — may naturally assume that their Ozempic pen should be used the same way. This is a dangerous assumption.
The Correct Way to Take Semaglutide Injections
Here is what every Indian patient starting on Ozempic, Wegovy, or generic semaglutide must know. Semaglutide injections are given once per week — on the same day each week, at any time of day, with or without food. You do not inject daily. The recommended starting dose is 0.25 mg per week for the first four weeks. This low starting dose is not the therapeutic dose — it is specifically designed to let your body adjust to the medication and minimize nausea. After four weeks, your doctor will typically increase to 0.5 mg. Do not skip ahead to a higher dose on your own.

If you miss a dose and your next scheduled dose is more than two days away, take the missed dose as soon as you remember. If your next scheduled dose is within two days, skip the missed dose and continue with your regular weekly schedule. Never take two doses at once to make up for a missed one.
If you experience severe nausea, repeated vomiting, inability to keep fluids down, or any symptoms that worry you after an injection, contact your doctor immediately. Do not wait to see if symptoms resolve on their own, particularly in the first few months on the medication.
What to Do If You Think You Have Taken Too Much
If you or a family member believes you have taken more semaglutide than prescribed — for example, if you accidentally injected twice in one week, or used a higher dose pen than intended — contact your doctor immediately or go to a hospital emergency department. The most likely symptoms of excess semaglutide are severe nausea, vomiting, and low blood sugar, particularly if you are also on insulin or sulfonylurea diabetes medication. In India, you can also call the National Poison Information Centre at AIIMS Delhi: 011-26593677.
The researchers at UT San Antonio found that with better patient education at the time of prescribing and at the pharmacy, most of these adverse events are entirely preventable. The drug itself is not the problem — the knowledge gap is.
