Side Effects Of Masseter Botox -You Should Never Ignore

Masseter Botox isn’t itself a bad guy—but like any treatment, it can have side effects. By the way, it’s generally considered safe when done carefully; however, these are some possible issues:

Masseter Botox Side Effects

Here are several effects that you may feel after Masseter Botox:

Injection site reactions 

Pain, swelling, and bruising may appear at the injection site.

Muscle weakness 

Temporary weakness may appear in the masseter muscles or their surroundings, potentially affecting chewing and facial expressions. 

Asymmetry

In some cases, due to atrophy or muscle weakness, Botox can lead to an uneven appearance.

Dry skin

Skin might be dry due to the decrease in sweat gland activity.

Swallowing or breathing difficulty 

Although it’s rare, sometimes Botox weakens the muscles that are used for swallowing or breathing—it may lead to serious complications.

Jaw pain or locking 

Many of us feel jaw pain, stiffness, or locking after the treatment. 

Botox migration to the surrounding muscles

In rare cases, masseter Botox can migrate to other muscles, which results in weakness and unwanted facial movements.

Blurred vision or any vision problems

This happens if the Botox spreads to the eye muscles or affects  

If Botox spreads to the eye muscles or affects nerve signaling, the eyes may not function properly, leading to blurry vision, double vision, or difficulty focusing.

Numbness

Sometimes, Masseter Botox can cause temporary numbness or loss of feeling near the jaw. This happens when it affects nearby sensory nerves as well as muscles. It usually lasts a few days to a couple of weeks and goes away on its own.

Severe upset stomach

Masseter Botox may cause strong stomach pain, nausea, vomiting, or diarrhea. If symptoms are severe or last long, seek medical help immediately.

Symptoms of a urinary tract infection (UTI) or blood in urine

You may feel burning while urinating, need to urinate more often, notice cloudy urine, or see blood in it. It happens when the Botox affects the nerve bladders. 

Slurred speech

Slurred speech can occur if Masseter Botox affects the muscles around your mouth or jaw that control speech. In this condition, your words may sound unclear, slow, or harder to pronounce. It’s usually temporary, but if it happens, you should inform your doctor.

Drooping eyelid or eyebrow

If Botox spreads to nearby muscles that lift the eyelid or eyebrow areas. This may cause one side of the face to look uneven or heavier. It’s generally temporary and improves as the Botox effect wears off.

Headache

After Botox, if the muscles feel tight or the body is adjusting to the treatment. It usually feels like pressure or pain in the forehead or temples and often goes away within a few days.

Flu-like symptoms

Flu-like symptoms after Botox may include mild fever, chills, tiredness, and body aches. These usually appear within a day or two and often fade on their own in a short time.

Drooling

It happens if the facial muscles that control the mouth become temporarily weak. This may cause saliva to escape while speaking or eating until the muscles regain full strength.

Dizziness or fainting

Dizziness or fainting after Botox can occur if your blood pressure drops or you feel lightheaded, often due to anxiety, pain, or a reaction during or after the injection. You might feel unsteady, weak, or even lose consciousness for a short time.

Mandibular Bone Loss

If you repeat Masseter Botox, the muscle activity reduces over time. Then the jawbone gets less stimulation and pressure, while it needs to stay strong. As a result, the bone may gradually lose density and change shape, leading to mandibular bone loss.

• These are just rare side effects of Masseter Botox; no medical proof is available that says each Botox dose leads to these issues. So don’t lose heart after knowing about these risks. Just choose the experienced practitioner—you’ll likely get the best results!
