Question : can you cut 1mg guanfacine in half?

Answered by Dr. Seikhoo Bishnoi (1 hour later)

Brief Answer:
Better to avoid cutting the tablet because bioavailability will be affected

Detailed Answer:
Hi, thanks for asking from HCM

Guanfacine is normally available in prolonged or extended release tablets. The tablet should not cut in half because this will increase the absorption and exact division could not be done. If the tablet is not prolonged release then you can cut till you get 0.5 mg tablets.

Thanks. Take care
