How long does it take to see Botox effects for palm sweating? How long for full effect? Can I have a 100% sweat free handshake?

It takes 3-5 days to see the effect, 14 days to get the full effect of botox.  Whether or not you will get a 100% resolution of your swelling is impossible to predict.  Most people don't get 100% improvement but enough to make the treatment worth it.  For some patients the improvement is very minimal.

Thank you for your question!  It typically take up to 7-10 days to take full effect for BoTox.  The amount injected into your palms is a reasonable dose, however, the amount is individualized for each patient.  It may be that you simply need more in each palm - up to 100/palm is also reasonable.  Await the entire period for effects and discuss with your injector if your results are not satisfactory.  Results can never be guaranteed and I am unsure if your palmar hyperhidrosis will ever completely resolve despite these treatments.  Consideration for other oral medications may help, especially if the reason is for anxiety or phobias, etc.  Hope that this helps!  Best wishes!

Botox can take 7 to10 days for effectiveness to reach its maximum potential. The use of 50 units per palm is a safe recommended dosage for this treatment. However, effectiveness is individualized and the each palm may require up to 100 units for cessation of palmar hyperhidrosis.
