    Studies report an average weight loss as much as 15 percent with 70 mg of phendimetrazine three times per day, however, considering side effects, the optimum dose may be 70 mg twice a day. REFERENCES

    Thank you for this review. The regular dosage for Bontril is 35mg x 3 a day though...seems the study used a bit more.

    I am still curious about how it works compared to phentermine. Thanks again.

    Several studies were reviewed here.

    Some of the studies were dosage studies trying to determine what dose worked best. That is why they tried higher doses.

    70 mg three times per day caused the most weight loss, but also caused a number of side effects.

    70 mg twice a day seemed to cause the most weight loss with fewer side effects.

    Yes, you are right. The normal dose is 35 mg three times per day.

    Phendimetrazine is a symptathomimetic drug, as is phentermine. The both work mainly via noradrenaline.
