Where does botulinum toxin come from?

Botulinum toxin is made in the laboratory, from the extraction of a specific type of bacteria, similar to how vaccines are made. But you shouldn't be afraid, the substance goes through a process to have the expected action and diluted to be applied. By going through special processes before being marketed, the substance does not cause any type of infection and the chance of allergy is very low. The procedure is very safe and side effects are rare and when they do occur, they are very mild.

Its main action is to relax the muscle, when applied directly to the muscle group, and to inhibit the painful impulse, when applied to the subcutaneous tissue. Its action depends on the dose, so it is common to adjust the doses according to the patient and the indication throughout the applications.

How Botox® works

Botulinum toxin has several actions in the body.

When injected into the muscle, it relaxes the muscle. So it can be very helpful when there is spasticity or abnormal body movements. It acts on the motor neuron (the nerve that goes to the muscle to make it move), reducing or preventing the vesicles from exocytosis and leaving for the synaptic cleft to release the neurotransmitter. 

They also act on sensory neurons, decreasing sensory conduction by the same mechanism, allowing their use in the treatment of many painful syndromes.

Its action depends on the dose, so it is common to adjust the doses according to the patient and the indication throughout the applications.

The big problem is when Botox is performed by someone who has not been trained for it.

Indications such as headache, spasticity, dystonia, spasms, should be performed by atrained doctor, in general, theneurologist!

The best procedure, however, is the one performed at the right time and with precise and individualized indication. Minimally invasive procedures represent one of the stages of the patient's rehabilitation program, but not the only one. The treatment has to be discussed with the specialist and the choice of the best option has to be shared between doctor and patient.

Botulinum toxin is a great weapon in the arsenal against different problems, from headaches to muscle contractions. But, like other treatments, it is not infallible and should not be seen as a miracle cure for the problem. 

The most important thing is follow-up and follow-up with theneurologist doctor,so that it is possible to discuss the best alternative in each situation.

We must remember that the best procedure is the one performed at the right time and with theprecise indication and individualized. Minimally invasive procedures represent one of the stages of the patient's rehabilitation program, but not the only one.

The treatment has to be discussed with the specialist and the choice of the best option has to be shared between doctor and patient.
