Botox injections can cause flu-like symptoms because of the presence of botulinum toxin in the treatment. This neurotoxin blocks the signals that tell your muscles to contract, resulting in muscle relaxation and wrinkle reduction. However, since the body perceives the toxin as a foreign substance, it triggers an immune response that leads to flu-like symptoms.

A mild-to-moderate symptom usually appears shortly after botox treatment, and the feeling of flu typically lasts for 24 hours. The most common side effects are upper respiratory infection, fever, and tiredness.

In this blog post, we'll discuss how long flu-like symptoms last after botox, factors that affect the duration of flu-like symptoms after botox and tips for reducing the severity of flu-like symptoms.

An injection of botox can cause flu-like symptoms for 24 to 48 hours, or even a week sometimes. The duration of these symptoms varies from person to person, as everyone's reactions to the treatment can differ. The time of these symptoms can vary, depending on several factors. If you're considering botox, it's essential to understand what can affect the course of flu-like symptoms. Various factors can affect how long flu-like symptoms from botox last. These factors include:

Amount of Botox Injected

The amount injected can affect the duration of flu-like symptoms. The more botox is used, the higher the chance of experiencing these symptoms. If only a small amount of botox is used, the symptoms may not be as severe, which may mean a shorter duration.

Injection Site

The injection site can also influence the severity of flu-like symptoms. The symptoms may last longer if botox is injected in an area with more muscle movement, such as the forehead. This is because the muscle movement can cause the botox to spread to other nearby muscles, increasing the likelihood of flu-like symptoms.

Patient's Immune System

The immune system has a critical role in how the body reacts to botox. The flu-like symptoms may only last for a short time if the immune system is robust. These symptoms may linger more if the patient has a weaker immune system.

Pre-Treatment Habits

Pre-treatment habits can also affect how long flu-like symptoms last. Patients who smoke, consume alcohol regularly or have poor sleep habits may experience these symptoms for longer.

Type Of Botox Used

Different botox can have varying effects on the duration of flu-like symptoms. For example, some newer versions of botox may not cause flu-like symptoms at all. Older versions of botox may have a higher chance of causing these symptoms and may have a longer duration.


Proper aftercare also affects flu-like symptoms after botox. Inflammation and swelling can be reduced by avoiding strenuous exercise and staying hydrated. Taking an over-the-counter pain medication can help to ease any discomfort associated with the treatment.
