Cautions
Therapy may impair ability of patient to engage in potentially hazardous activities such as operating machinery or driving motor vehicle; the patient should be cautioned accordingly
Prolonged use may induce dependence with withdrawal syndrome on cessation of therapy
Hallucinations have occurred rarely following high doses of the drug
Several cases of toxic psychosis reported following excessive use of drug; some have been reported in which recommended dose appears not to have been exceeded; new onset of mania may occur with stimulant use; ovserve for symptoms of aggression and/or hostility; psychosis has been abated after drug discontinued
When central nervous system active agents used, consideration must always be given to possibility of adverse interactions with alcohol
Reports suggest the drug may increase convulsions in some patients with seizure disorders; therapy should be carefully monitored; titration of dose or discontinuance of therapy may be necessary
Stimulants may unmask tics in Tourette’s syndrome; use with caution
Use caution in patients with diabetes mellitus; requirements of antidiabetic agents may be altered with anorexiants and concomitant dietary restrictions
Pulmonary hypertension
- Use of anorectic agents, including diethylpropion, associated with increased risk of developing pulmonary hypertension, a rare, but often fatal disorder; use of anorectic agents for > 3 months associated with 23-fold increase in risk of developing pulmonary hypertension; increased risk of pulmonary hypertension with repeated courses of therapy cannot be excluded
- Onset or aggravation of exertional dyspnea, or unexplained symptoms of angina pectoris, syncope, or lower extremity edema suggest possibility of occurrence of pulmonary hypertension; if patient develops these symptoms discontinue therapy, and evaluate patient for pulmonary hypertension
Valvular heart disease
- Valvular heart disease associated with use of some anorectic agents reported; possible contributing factors include use for extended periods of time, higher than recommended dose, and/or use in combination with other anorectic drugs
- Valvulopathy has been very rarely reported with monotherapy; potential risk of possible serious adverse effects such as valvular heart disease and pulmonary hypertension should be assessed carefully against potential benefit of weight loss; consider baseline cardiac evaluation to detect preexisting valvular heart diseases or pulmonary hypertension prior to initiation of treatment
- Therapy not recommended in patients with known heart murmur or valvular heart disease; echocardiogram during and after treatment could be useful for detecting any valvular disorders which may occur
- To limit unwarranted exposure and risks, treatment should be continued only if patient has satisfactory weight loss within first 4 weeks of treatment (eg, weight loss of at least 4 pounds, or as determined by physician and patient); therapy not recommended for patients who used any anorectic agents within prior year
- If tolerance develops, do not exceed recommended dose in attempt to increase effect; discontinue drug instead
Pregnancy & Lactation
Pregnancy Category: B
Lactation: Excreted in breast milk, use caution
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Amphetamine-related anorexigenic agent; action in reducing apetite may be secondary to CNS effects that may involve stimulation of hypothalamus to release norepinephrine
Pharmacokinetics
Metabolism: Undergoes reduction and N-dealkylation to form active metabolites
Duration: 4 hr
Half-life elimination: 4-6 hr (aminoketone metabolites)
Excretion: primarily urine (>75%)

DIETHYLPROPION - ORAL
(dye-ETH-il-PROE-pee-on)
COMMON BRAND NAME(S): Tenuate
USES: Diethylpropion is used along with a doctor-approved, reduced-calorie diet, exercise, and behavior change program to help you lose weight. It is used in people who are significantly overweight (obese) and have not been able to lose enough weight with diet and exercise alone. Losing weight and keeping it off can reduce the many health risks that come with obesity, including heart disease, diabetes, high blood pressure, and a shorter life.It is not known how this medication helps people to lose weight. It may work by decreasing your appetite, increasing the amount of energy used by your body, or by affecting certain parts of the brain. This medication is an appetite suppressant and belongs to a class of drugs called sympathomimetic amines.
HOW TO USE: Take the immediate-release form of this medication by mouth, usually 3 times a day 1 hour before meals or as directed by your doctor. If late-night eating is a problem, your doctor may direct you to take another dose in the evening. Taking this medication late in the day may cause trouble sleeping (insomnia).The extended-release form of diethylpropion is usually taken once a day in the mid-morning. Do not crush or chew extended-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Swallow the tablets whole.The dosage is based on your medical condition and response to therapy. Your doctor will adjust the dose to find the best dose for you. Use this medication regularly and exactly as prescribed in order to get the most benefit from it. To help you remember, take it at the same time(s) each day.Diethylpropion is usually taken for only a few weeks at a time. It should not be taken with other appetite suppressants (see also Drug Interaction section). The possibility of serious side effects increases with longer use of this medication and use of this drug along with certain other diet drugs.If you suddenly stop using this medication, you may have withdrawal symptoms (such as depression, severe tiredness). To help prevent withdrawal, your doctor may lower your dose slowly. Withdrawal is more likely if you have used diethylpropion for a long time or in high doses. Tell your doctor or pharmacist right away if you have withdrawal.Though it helps many people, this medication may sometimes cause addiction. This risk may be higher if you have a substance use disorder (such as overuse of or addiction to drugs/alcohol). Do not increase your dose, take it more often, or use it for a longer time than prescribed. Properly stop the medication when so directed.You should see some weight loss soon after you start this medication. Tell your doctor if you do not see at least 4 pounds of weight loss within 4 weeks of starting this medication. This medication may stop working well after you have been taking it for a while. Talk with your doctor if this medication stops working well. Do not increase the dose unless directed by your doctor. Your doctor may direct you to stop taking this medication.
SIDE EFFECTS: Dizziness, dry mouth, difficulty sleeping, irritability, nausea, vomiting, diarrhea, or constipation may occur.
