Can botox spread to your vital organs? Is 45 units a lot for your first time? (photos)

I've had a consultation and booked my appointment for next week. It's my first time having botox and it's been recommended I have 45 units for the areas of my forhead, frown lines and the area under my eye just over my checks, I sleep on my side and end up with creases in this area as a result. 45 units seems a lot to me for my first time. Is it to much? I'm also very nervous I might have a bad reaction, I quite scared even thinking about the procedure, is it possible for botox to travel to vital organs?

Botox and Vital Organs

Botox works by blocking signals from the nerves to the muscles. The injected muscle can then no longer contract, which causes the wrinkles to relax and soften. Botox is most often used on forehead lines, crow's feet (lines around the eye) and frown lines. Receiving 45 units for these 3 treated areas is the correct amount. You do not have to worry about Botox spreading to your vital organs. Botox can only spread about a centimeter from the injection site. I recommend seeing an expert injector. Best of Luck!

45 units is not an unreasonable dose for all of those areas.  If it's your first time, it may be ok to use a smaller dose to begin and then add more as needed.  But botox will not travel to vital organs when used appropriately for cosmetic use.

Botox dose and spread

Thank you for your question mariama3. I understand your concern. Botox is a purified protein used to address wrinkles associated with facial expression. 45 units is not a high dose, some people have over 100 units in a single treatment and when used for neurological purposes over 300 units may be performed at a given session. Such small doses are used for the small muscles in the face. To affect muscles associated with breathing much higher doses (100 times or more) are likely required. Further there is minimal absorption of Botox into the blood stream and I advise my patients not to worry about these things. Please consult with a doctor for specific recommendations. Good luck!

I think 45 units is very reasonable for the treatment areas you described. To put it in perspective, studies show the maximum recommended dose per session is around 600 units. The toxic dose is in the 3000 unit range. You are quite safe at 45 units with no risk to vital organs.

Botox treatment - dosing and safety

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

I often tell patients that Botox is one of the safest procedures I perform in my clinic. Botox is an FDA approved treatment with years of clinic research and data supporting its safety. I would not be worried. The dosing of 45 units seems about right for the 3 areas you are having treated.

Botox is safe and when injected only works locally, it doesn't get absorbed in the body.  45 units depends on the places injected and seems normal for brow, forehead, and eyes -- maybe even low.  Best, Dr. Emer.

Can 45 units of Botox spread to my vital organs?

This is proper dosing for the areas you are getting treated. The Botox can spread by about a centimeter from it injection site. It will not go to your vital organs. There should be no worry about that at all.

Vital organs.

Botox and Dysport are safe and FDA approved with long records of great results. In our office, we have injected over a thousand patients with good results. I do not believe 45 units is too much and is what I would routinely use to treat the frown lines and forehead wrinkles. Make sure you're using a certified injector. Best of luck, Dr. ALDO :)

Botox spreading to organs?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Hi mariama3. Great question. Botox is one of the most popular aesthetic procedure in the world. There is a reason so many people want it.... it works!! 45 units is not a big deal depending on where it is needed. I sometimes use more than 45units on some patients. Botox will not get into your organs. It is injected too close to the skin to go that deep into your organs. Don't worry. However I must say you need to do your due diligence and make sure you have vetted this doctor. Make sure he or she has done many injections. Complications from Botox do exsist and you must have the doctor explain theses before your injection. Being a first timer I understand your apprehension, but if done properly you might just become addicted!!.  Cheers.

Botox doesn't spread to vital organs

Given your overall apprehension and statements like "I might have a bad reaction", I strongly advise you against having this elective cosmetic procedure. No one NEEDS Botox especially if it makes them this nervous.
