Botulinum Toxin Type B: pH Change Reduces Injection Pain, Retains Efficacy

CONCLUSION: Botulinum toxin Type A resistance is documented to 3 BTX-A brands in 2 patients. They had received low doses of Type A toxin, they responded to Type B toxin. Injection pain of the acidic solution of BTX-B neurotoxin was reduced and efficacy not compromised by changing pH of BTX-B solution to pH 7.5. This method improved patient tolerance to BTX-B injections.
