How Does Phentermine Work |
 |
|
Phentermine works in the
brain to decrease appetite. It should be used for only short
periods (for a few weeks) as part of a physician-guided weight
loss program, which includes a reduced calorie diet and
exercise. The safety and effectiveness of using Phentermine
with other drugs for weight loss has not been proven.
Weight loss is greatest during the first few weeks of therapy
but typically levels off with continued use. Weight loss can
vary from person to person and Phentermine does not work for
everyone.
Directions on Taking Phentermine:
• Phentermine should be taken on an empty stomach, once daily,
prior to breakfast. If in tablet form, the tablet may be
broken or cut in half. Do NOT break, crush, or chew tablets.
• As Phentermine may disrupt normal sleep patterns, avoid
taking a dose late in the day. If taking more than one dose a
day, take the last dose approx. 4-6 hours prior to going to
bed.
• The following information is specific only to the average
doses of Phentermine. The recommended dose of Phentermine may
be different for different patients. If your dose is
different, do NOT change it unless your doctor tells you to do
so.
• Oral dosage form (Capsules) - 15 to 37.5 mg once/day before
breakfast or 1-2 hours after breakfast.
• Oral dosage form (Tablets) - 15 to 37.5 mg once/day before
breakfast or 1-2 hours after breakfast. Instead of taking it
once a day, your doctor may tell you to take 15 to 37.5 mg in
divided doses one-half hour before meals.
• Oral resin dosage form (Capsules) - 15 to 30 mg once/day
before breakfast.
Adults age 60 and over may need a reduced dosage.
Consult your physician. |
