Effects to watch for
Each product has its own effects, like the nausea of the first weeks with retatrutide. Choose yours to see what is common, what can also happen, and how to reduce it.

What applies to every pen
The injection-site reaction
Slight redness, tenderness or a little swelling in the hours that follow: this is the most common reaction, whatever the product. It usually clears up within a day or two, and a cold compress helps.
Pain that increases, or warmth and swelling that get worse after two days, deserve a professional opinion.
The first few days
A mild headache, unusual tiredness or slight dizziness are possible in the first few days with a new product. Drinking enough water and sleeping well help, and this stage rarely lasts more than a week.
Good habits
- Follow your protocol, without raising the dose on your own.
- Change the injection site every time.
- Drink water regularly through the day.
- Keep your mixed pen in the fridge at all times.
- Write down what you notice: it is useful if you talk to a healthcare professional.
When to talk to a professional
If a symptom is severe, lingers or worries you, stop the product and talk to a healthcare professional. An immediate reaction after the injection, such as trouble breathing or swelling of the face, needs medical care right away.
