side effects of Botox:10 side effect you should know-2023

Botox injections are injections that contain a neurotoxin that relaxes the muscle and prevents it from moving by preventing nerve impulses from reaching the muscle. Botox injections have several cosmetic and medical benefits, the most common of which is its use to reduce skin wrinkles, and it is also used for several medical conditions such as lazy eye, hyperactivity Bladder, sweating, neck pain, migraine prevention and many other medical conditions.

The drug contained in Botox injections consists of the same toxin that causes food poisoning, but it is present in a more pure form, which meets medical control standards. the U.S. Food and Drug Administration has approved these standards. For more important details, click here

How Botox injections work?

Botox injections contain a neurotoxin. Neurotoxins target the nervous system. These neurotoxins disrupt the transmission of nerve signals between neurons and muscles that stimulate muscle contraction. Through this method, neurotoxins will cause temporary muscle paralysis.

Muscle contraction needs a chemical called acetylcholine, neurons work to deliver acetylcholine to muscles, acetylcholine binds to receptors on muscle cells and causes cells to contract or shorten.
The neurotoxin works to block this process, causing muscle paralysis. In this way, the muscles are less.

How does neck botox work?

After years of hyperactivity of this muscle and its frequent use, it becomes larger in size, and with our age and sagging of the skin, the vertical straps become more clear, which adds an unflattering appearance to the neck.
So here is how Botox injections work as described above, we will know that the neurotoxin present in Botox injections will work to prevent hyperactivity of the muscle and thus relax the muscle and greatly reduce the prominence of the muscle.
The results take several days to appear and last for 4 to 6 months until they disappear and the muscle returns to prominence again. The procedure can be repeated after the results disappear.


- The specialist doctor will evaluate the medical history and previous cosmetic treatments.
- Identify skin problems and cosmetic goals.
- If conditions are appropriate, Botox can be performed on the same day.
- Dosage depends on the treatment area and muscle size for each patient.
The procedure does not take more than ten minutes.
A local anesthetic may be used.
- The treatment does not affect the daily schedule, it is possible to return to activities normally after using Botox injections.
An ice pack can be applied to reduce swelling after the injection.
- There may be a follow-up from the specialist doctor to check the results of the injection.

 side effects:

1. Bruises:
After a Botox session, bruising is a common side effect. This occurs when the injection needle accidentally damages a blood vessel, causing blood to leak into the surrounding tissues. Bruising occurs even with experienced medical providers because of the many branches in the blood vessels.

2. Swelling:
The injection needle causes slight irritation to the skin and underlying tissues, which leads to activation of a local inflammatory response and swelling and redness around the injection site. This side effect is usually mild and goes away naturally within a few days. You can use ice packs to relieve symptoms.

3. Numbness:
Numbness is one of the common side effects of Botox injections. When injected into muscles, Botox blocks the release of the neurotransmitter acetylcholine, which contributes to muscle contraction. This results in a temporary decrease in muscle activity, which may cause numbness or a loss of sensation in the treated area. This effect is usually temporary and wears off within a few hours.

4. Infection:
If the needle pierces the skin and reaches the muscle, bacteria can also be transmitted. To reduce the risk of infection, the treatment area should be cleaned thoroughly before each injection. Bacterial infections as a result of Botox are more common when injections are given by unqualified people who do not adhere to the usual preparatory procedures.

5. Bumps on the surface of the skin:
After a Botox session, small bumps may appear on the surface of the skin. This is due to the microinjection and the reaction of the skin to the Botox. Although they may appear noticeable for a short time, they are usually mild and disappear on their own within a short period of time, due to the evenly spread of the injected material.

6. Headache:
One of the common effects that you may notice after a Botox session is headache. This could be due to the effect of Botox on the nervous system and the balance of chemicals in the body. The headache is often mild and can last for a short time. If this is bothersome, a healthcare provider can be consulted for advice on how to relieve symptoms.

7. Droopy Eyelids:
After a Botox session, drooping eyelids may occur in some cases. This is usually the result of injecting Botox into the areas around the eyes inaccurately, affecting the muscles responsible for supporting the eyelids. If the prolapse is mild, it may disappear over time. In the case of a prominent and troublesome prolapse, intervention can be done to correct the problem.

8. Muscle weakness:
A rare side effect of Botox is muscle weakness. Muscle weakness occurs when the neurotoxin in Botox injections travels from the injection site to other non-targeted areas of the body, causing its effect. This effect is unusual and occurs at a very low rate. If there is any unusual muscle weakness after a Botox session, a healthcare provider should be contacted immediately.

9. Swallowing difficulties:
Dysphagia or difficulty swallowing can result from the effect of Botox on the muscles responsible for the swallowing process. This is usually a temporary effect and rarely lasts for long. If you have significant difficulty swallowing after a Botox session, it is recommended to speak with your healthcare provider for an evaluation.

10. Blurred vision:
The phenomenon of blurred vision appears rarely after a Botox session. This is due to the effect of Botox on the function of the neurotransmitter, which is involved in communication between nerves and muscles. Although rare, this effect can last for a while before the patient's vision returns to normal. If you notice any unusual change in your vision, you should consult your healthcare provider right away.


According to the American Society of Plastic Surgeons (ASPS), a unit of Botox often costs $10 to $15. The number of units used varies depending on the type of drug and the area to be injected. One person often uses 20 to 40 units, so the total cost ranges from $300 to $600.
