BOTULAX is a peripheral muscle relaxant that contains purified botulinum toxin type A and sodium chloride. The mechanism of action of the product is based on the ability of botulinum toxin type A to block the transmission of nerve impulses. Intramuscular administration of the toxin disrupts the synthesis of acetylcholine (a neurotransmitter that ensures neuromuscular conduction) and leads to temporary paralysis of the facial muscles. Frozen facial expressions help relax muscles and smooth wrinkles.

Understanding Botulax and Its Applications

Botulax is derived from the bacterium Clostridium botulinum and works by blocking nerve signals to the muscles, causing temporary muscle paralysis. This property makes it invaluable in treating conditions like chronic migraines, cervical dystonia, and overactive bladder. In cosmetic applications, Botulax is used to reduce the appearance of facial wrinkles by relaxing the underlying muscles.

Importance of Proper Reconstitution

Reconstitution is the process of mixing a lyophilized (freeze-dried) drug with a diluent to prepare it for injection. For Botulax, the diluent commonly used is sterile saline (0.9% sodium chloride). Proper reconstitution is crucial because it ensures the drug's stability and efficacy, minimizes potential side effects, and allows for accurate dosing.

Determining the Correct Amount of Saline


The amount of saline used for reconstituting Botulax depends on the desired concentration and the specific treatment protocol. For 100 units of Botulax, the recommended volume of saline can vary, but a common practice is to use 2.5 ml of sterile saline. This dilution results in a concentration of 4 units per 0.1 ml, which is suitable for most cosmetic and medical applications. However, the concentration can be adjusted based on the practitioner's preference and the treatment area.

Step-by-Step Guide to Reconstituting Botulax

Materials Needed:

  • Vial of Botulax (100 units)

  • Sterile saline (0.9% sodium chloride)

  • Syringe (preferably with a 21-25G needle)

  • Alcohol swabs


  • Ensure a clean and sterile work environment.

  • Wash hands thoroughly and wear gloves.

  • Inspect the Botulax vial for any damage or discoloration.

Sterilize the Vial:

Use an alcohol swab to clean the rubber stopper of the Botulax vial.

Draw Saline into the Syringe:

  • Use a new syringe to draw the recommended amount of sterile saline (2.5 ml) from its vial.

  • Ensure no air bubbles are present in the syringe by tapping and expelling any trapped air.

Reconstitute Botulax:

  • Insert the syringe needle through the rubber stopper of the Botulax vial.

  • Slowly inject the saline into the vial. Aim to let the saline run down the inside of the vial to avoid foaming.

  • Gently swirl the vial to mix the contents. Do not shake the vial vigorously as it may denature the protein.

Inspect the Solution:

After mixing, the solution should be clear and free of any particles. If the solution is cloudy or contains particulate matter, it should not be used.

Drawing the Reconstituted Solution:

  • Use a new syringe to draw the reconstituted Botulax solution.

  • Ensure accurate measurement by using syringes with appropriate markings.

Administration of Reconstituted Botulax

Injection Sites:

The injection sites for Botulax depend on the condition being treated. For cosmetic purposes, common sites include the forehead, glabella (between the eyebrows), and crow’s feet (around the eyes). For medical treatments, the injection sites vary based on the specific muscle groups involved.


Patient Preparation:

  • Ensure the patient is in a comfortable position.

  • Clean the injection site with an alcohol swab.


  • Use a fine needle (30-32 gauge) for the injection.

  • Insert the needle at the appropriate angle for the target muscle.

  • Inject the solution slowly and steadily.

Please note that these steps are a general guide. It's important to follow the specific instructions provided with your Botulax product.

Initial results are usually seen within three days of injection, with the peak effect occurring at one to two weeks post-treatment. The effects usually last for approximately 3-6 months, after which the procedure can be repeated. If the initial treatment's response is considered insufficient (lasting less than two months), the dose may be increased by up to two-fold. However, it is generally not beneficial to inject more than 5.0 units per site. Some tolerance may develop if treatments are administered more frequently than every three months, and long-lasting effects are rare. The total cumulative dose of Botulax® 100 in a 30-day period should not exceed 200 units.

Once the powder is reconstituted, record the date and time of the process on the vial label and use it within 24 hours. During this time, the solution must be stored in a refrigerator at 2-8°C.

For administration, your practitioner can guide you about the initial recommended dosage. Once applied, you will observe the cosmetic effect of Botulax within three to seven days. The impact reaches a peak at one to two weeks post-treatment.
