How to properly dose Botox and Dysport so as not to harm the patient
Dose of botulinum toxin preparations must be based on strict recommendations formed after numerous studies. Botox is dosed in international units or action units. This means that one unit of the drug is capable of causing death in half of the group of laboratory mice that received the drug intraperitoneally. If a specialist uses dysport, in order to properly dose it, it is necessary to increase the dose of Botox recommended in this particular case by 3-5 times, since it is more active than dysport.
The lethal dose of botulinum toxin for humans is not known for certain today, but it is believed that a patient weighing 70 kg can be fatal with the introduction of 3000 units of botulinum toxin. That is why, during the procedure, it is allowed to inject no more than 50 units of the drug at one point, and no more than 400 units in total amount per procedure.
Features of the preparation and use of botulinum toxin preparations
There are some features of the use of botulinum toxin preparations that every specialist who uses them in their practice must remember:
- Botox preparations can be stored for 4 years, provided they are frozen at temperatures below -5°C.
- Immediately before use, the Botox bottle must be add 1-4 ml of sterile isotonic sodium chloride solution, and it is strictly forbidden to use distilled water to dilute the Botox, as this can be dangerous for the patient.
- The finished solution of Botox can be stored in the refrigerator for no more than 6 hours, and it is forbidden to re-freeze the already diluted toxin.
- Insulin syringes are used for Botox injections into superficial muscles, the needle length of which is 12.7 mm, while longer needles are needed to deliver the drug into deep muscles – 38 mm.
- Injection points and dosage of botulinum toxin preparations are determined separately for each patient and depends primarily on the nature, severity and localization of muscle hyperactivity.
Side effects after botulinum toxin injections
Side effects are extremely rare if botulinum toxin preparations are properly dosed and administered. Immediately after the injection of drugs, specialists most often face the problem of tissue descent as a result of the spread of toxin from one muscle to another, as well as moderate violation of the act of swallowing when Botox is injected into the sternocleidomastoid and submental muscles.
Systemic side effects can be manifested in the form of fatigue and general weakness of the body, but at present they are practically not observed. Proper use of botulinum toxin preparations, taking into account all the individual characteristics of the patient's body, will help prevent any side effects.
The best prevention of any complications of botulinum toxin preparations is the knowledge of a specialist about the features of their use.
