Treating Weight Loss Injections Side Effects

Most side effects from weight loss injections are mild and go away on their own a few days to a few weeks after starting treatment or moving up a dose. Still, there are things you could try to help improve your side effects while you've got them.

About this service

Common side effects from weight loss injections include:

  • headaches
  • throwing up
  • diarrhoea
  • constipation
  • feeling sick
  • stomach pain
  • tiredness

While these do usually go away on their own a few days or weeks after you start your treatment or moved to a higher dose, you can be proactive about managing them. There are a range of over-the-counter treatments they could help improve your side effects symptoms, so you can have a smoother start to your weight loss journey and get on with the things that really matter to you.

Please note: If your side effects are severe, don't go away within a few weeks, or are seriously affecting your day-to-day life, please get in touch with a doctor.
