How Long Do Botox Side Effects Last?

As with any type of medical procedure, there may be side effects of receiving your Botox injections. While most are not severe, it’s important to be mindful of your body following your botox experience.

We believe that having all the information in advance will give you peace of mind and feel more confident in your procedure. Therefore, we explain potential side effects and how long they may last.

Understanding the Side Effects of Botox

The types of side effects you may experience are dependent on the site of injection.

If you get Botox around the eyes, you may notice your eyes are drooping slightly. Meanwhile, if you take Botox to treat an overactive bladder, you may discover some discomfort while urinating.

Botox is a common treatment for chronic migraines. The most common side effects in such cases are neck pain, headaches, muscle stiffness, muscle weakness, and pain or redness around the injection site.

However, here are some general side effects:

Mild Side Effects

  • Fever
  • Muscle aches
  • Cough
  • Dry mouth
  • Headache
  • Injection site reactions, such as pain or bleeding
  • Sore throat

It’s important to note that these side effects should be temporary. They should last only a few days or weeks at most. However, if you notice your side effects persisting or worsening within that time, contact your doctor.

Serious Side Effects

  • Allergic reactions
  • Difficulty breathing or swallowing
  • Blurry/watery eyes
  • Pain and redness in the eye
  • Urinary retention

These side effects are less common. However, if you are experiencing one or more of these, it’s important not to wait and see if it gets better. Call your doctor immediately.

Botox is used to improve your life, so its side effects should not be greater than the benefits. Fortunately, most do not last long, but being sensitive to your body’s reaction is important. Don’t hesitate to contact a professional if you have any questions or concerns.
