What is the side effect of over dose with botox A?

Botox (onabotulinumtoxinA) is a purified neurotoxin that is used in a variety of medical and cosmetic procedures. While it is generally considered safe when used in appropriate doses, there are a number of potential side effects, including:

- Muscle weakness: The most common side effect of Botox is temporary muscle weakness in the area where it is injected. This can make it difficult to perform certain movements, such as smiling, frowning, or raising the eyebrows.

- Bruising and swelling: Bruising and swelling can occur at the injection site, especially if the injection is given too superficially.

- Drooping eyelids: This can occur if the Botox is injected too close to the muscles that control eyelid movement.

- Dry mouth: Botox can affect the nerves that control saliva production, leading to dry mouth.

- Headache: Headache is a common side effect of Botox, especially in the first few days after the injection.

- Eyelid ptosis: This is a drooping of the eyelid that can occur if Botox is injected into the muscles that lift the eyelid.

- Difficulty swallowing: This can occur if Botox is injected into the muscles that are involved in swallowing.

- Allergic reactions: Although rare, allergic reactions to Botox can occur. Symptoms can include rash, hives, difficulty breathing, and swelling.

In some cases, an overdose of Botox can lead to more serious side effects, such as:

- Botulism: This is a rare but serious condition that can occur when Botox spreads to other parts of the body and affects the nerves that control breathing and muscle movement. Symptoms of botulism can include muscle weakness, difficulty breathing, and paralysis.

- Death: In rare cases, an overdose of Botox can be fatal.

It is important to note that the risk of side effects from Botox is generally low when the medication is used appropriately and by a qualified healthcare professional. However, it is important to be aware of the potential risks and benefits of Botox before undergoing treatment.
