What is Phentermine?

(from manufacturers site)

Phentermine is a powerful weight loss medication, but it’s not right for everyone. This prescription-only stimulant has a long list of potential side effects, and an even longer list of phentermine contraindications. Various pre-existing medical conditions or drug combinations increase the risk of experiencing these adverse reactions.

For this reason, a doctor needs to know about, and thoroughly review, your full medical history, current health status and all other medications & supplements before prescribing phentermine.

This article is intended for informational purposes only. We are not doctors and the information below does not in any way constitute or substitute a professional medical opinion. Always contact a licensed medical professional for medical advice.

Is Phentermine Legal?

Yes, Phentermine is F.D.A. approved as a medication and is well tolerated for decades. Phentermine is a controlled legal classed drug. Every individual state & country has its own law for its usage.

Relevant Medical History

During your first appointment, tell the prescribing doctor about your entire medical history. Make sure to mention if you have ever suffered from any of the conditions mentioned below, which carry additional phentermine warnings but may or may not prevent you from taking this medication.

Phentermine should NOT be used in patients with a history of [1,2,3]:

  • Cardiovascular disease, such as: coronary artery disease, stroke, irregular heart beat (arrhythmia), congestive heart failure or uncontrolled hypertension
  • Hyperthyroidism (overactive or high thyroid)
  • Glaucoma
  • Agitated states, including: anxiety, insomnia, mania, psychosis, schizophrenia
  • Eating disorders
  • Drug or alcohol abuse
  • Adverse reaction/allergy to sympathomimetic amines or similar

This medication is also contraindicated for women who are pregnant or nursing. The FDA classifies phentermine as Pregnancy Category X. Patients with the following conditions should exercise extra caution while taking phentermine:

  • Hypertension (high blood pressure)
  • Diabetes mellitus
  • Renal impairment (kidney disease)
  • Liver disease
  • Personal or family history of tics

Potential Drug Interactions

Many phentermine warnings involve drug interactions between phentermine and other medications

Phentermine is a powerful central nervous system stimulant that produces major biological changes, some of which can prove problematic when you have other substances in your system as well. As a result, many phentermine contraindications relate to potential drug interactions.
Take extra time to speak with your physician and pharmacist about potential drug interactions if you take any of the following medications or supplements:

1. Psychiatric Medications

Phentermine interacts with other many medications used to treat anxiety, depression and other mental disorders.
Tell your doctor about all such medications, including antidepressants such as monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs) and serotonin & norepinephrine reuptake inhibitors (SNRIs), or phenothiazine antipsychotics.
Do not take phentermine within 14 days of taking a monoamine oxidase inhibitor (MAOI).

Monoamine Oxidase Inhibitors

Monoamine oxidase inhibitors (MAOIs) are a class of antidepressants, which are also used to treat Parkinson’s disease. This early type of antidepressant has largely fallen out of favor due to its high potential for food & drug interactions, but it is still used in cases where other medications have proven ineffective (4).

Taking phentermine at the same time as, or within 14 days of taking, an MAOI increases the risk of hypertensive crisis (2). A hypertensive crisis is a sudden & severe increase in blood pressure that can lead to life-threatening complications, including stroke (5).

Currently-available MAOIs include:

  • Isocarboxazid (Marplan)
  • Phenelzine (Nardil)
  • Tranylcypromine (Parnate)
  • Linezolid (Zyvox)
  • Methylene blue (Provayblue)
  • Procarbazine (Matulane)
  • Rasagiline (Azilect)
  • Selegiline (Eldepryl, Emsam, Zelapar)

Tricyclic Antidepressants

Tricyclic antidepressants (TCAs) are an older type of medication that is used to treat depression, OCD and bipolar disorder. However, like MAOIs, TCAs have largely fallen out of favor because they tend to produce more side effects than newer antidepressants, and a TCA overdose is more dangerous (6).

TCAs should not be taken with phentermine because they inhibit norepinephrine reuptake and increase the body’s response to the stimulant. More specifically, this combination potentiates the pressure response and can cause a dangerous increase in blood pressure. Patients may experience symptoms like headaches, shaking, chest pain, irregular heart-rate or palpitations (7).

Common TCAs include:

  • Amitriptyline (Tryptizol)
  • Clomipramine (Anafranil)
  • Imipramine (Tofranil)
  • Lofepramine (Gamanil)
  • Nortriptyline (Allegron)

Selective Serotonin Reuptake Inhibitors

Selective serotonin reuptake inhibitors (SSRIs) and serotonin/norepinephrine reuptake inhibitors (SNRIs) are newer types of antidepressant medications that work by increasing levels of serotonin (and norepinephrine, in the case of SNRIs) in the brain. SSRIs are the most commonly prescribed antidepressants because they have relatively few side effects (8,9).

Do not take SSRIs or SNRIs with phentermine unless your doctor specifically prescribes the two medications together.

The combination of these two medications may produce serotonin syndrome: a serious medical condition that can prove fatal if left untreated. Serotonin syndrome is evidenced by irritability, hallucinations, rapid heart rate, low body temperature, sweating, shivering, frequent changes in blood pressure, tremors, abdominal cramping, nausea, vomiting and diarrhea (among other symptoms) (10).

Recent controlled clinical studies suggest that some patients can tolerate SSRIs/SNRIs (not MAOIs or TCAs) alongside low doses of phentermine or phentermine/topiramate (Qsymia). However, this study only included patients whose dose had been stable for at least 3 months prior to the initiation of phentermine, did not have suicidal ideation or had not had more than one episode of documents major depression (7).
Formal prescribing information still cautions against the use of these two medications together (2).

Common SSRIs include:

  • Citalopram (Celexa)
  • Escitalopram (Lexapro)
  • Fluoxetine (Prozac)
  • Paroxetine (Paxil, Pexeva)
  • Sertraline (Zoloft)
  • Vilazodone (Viibryd)

Common SSRIs include:

  • Desvenlafaxine (Pristiq, Khedezla)
  • Duloxetine (Cymbalta)
  • Levomilnacipran (Fetzima)
  • Venlafaxine (Effexor XR)


Phenothiazines (PTZ) are a class of antipsychotic medication used to treat serious mental and emotional health disorders like schizophrenia and agitation. Some forms of this drug are also used to manage other conditions such as severe hiccups, severe nausea & vomiting, moderate-to-severe pain and porphyria (10,11).

Phenothiazines should not be combined with phentermine because they interfere with the weight loss medication’s ability to suppress appetite, and may aggravate psychotic states (e.g. hallucinations or delusions) (7).

Common brands of phenothiazines include:

  • Compazine
  • Compro
  • Mellaril
  • Permitil
  • Phenadoz
  • Prolixin
  • Serentil
  • Sparine
  • Thorazine
  • Torecan
  • Trilafon
  • Phenergan

2 Other Stimulants

Phentermine is a powerful central nervous system stimulant (sympathomimetic) and should not be combined with other stimulants.

Combining multiple stimulants increases risk of cardiovascular and CNS side effects, including hypertensive crisis or cardiac arrhythmia (7). Many prescription and over-the-counter medications, as well as various street drugs, contain psychostimulant substances that can prove dangerous when combined with phentermine.

Do not combine phentermine with other stimulant medications, such as (12,13):

  • Acebutolol (Sectral)
  • Amphetamine (Adzenys XR-ODT, Dyanavel XR, Evekeo)
  • Dextroamphetamine (Dexedrine)
  • Dextroamphetamine + amphetamine (Adderall)
  • Epinephrine/Norepinephrine (EpiPen, Adrenalin, Levophed)
  • Lisdexamfetamine (Vyvanse)
  • Methylphenidate (Ritalin, Concerta)
  • Midodrine (ProAmatine)
  • Phenylephrine (Sudafed)
  • Pseudoephedrine (‎Afrinol, Sudafed, Sinutab) Or illicit (“street drug”) stimulants, such as:
  • Amphetamine

3. Medicines that Cause Drowsiness

Phentermine acts as a stimulant to increase energy and suppress appetite. It is dangerous to combine this sympathomimetic with substances that cause drowsiness due to an increased risk of adverse side effects, such as high blood pressure (14).

Tell your doctor if you take these, or any other, medications that cause drowsiness:

  • Opioid pain or cough relievers, such as: codeine, hydrocodone
  • Medications for sleep or anxiety, such as: alprazolam (Xanax), lorazepam (Ativan), zolpidem (Ambien)
  • Muscle relaxants, such as: carisoprodol (Soma), cyclobenzaprine (Flexeril)
  • Antihistamines, such as: cetirizine (Zyrtec), diphenhydramine (Benadryl)

Read the ingredient label on all new medications and supplements to avoid components that cause drowsiness. Consult with your pharmacist before taking any new medication or supplement alongside phentermine.

4. Blood Pressure Medications

Phentermine may cause a significant increase in blood pressure. Later, weight loss may decrease need for blood pressure medications.

Tell your doctor if you any take any medications for blood pressure, especially (14):

Tell your doctor if you take these, or any other, medications that cause drowsiness:

  • Guanethidine (Ismelin)
  • Methyldopa (Aldomet, Aldoril, Dopamet)
  • Beta blockers, such as: acebutolol (Sectral), atenolol (Tenormin), bisoprolol (Zebeta), metoprolol (Lopressor, Toprol XL), nadolol (Corgard), nebivolol (Bystolic), propranolol (Inderal, InnoPran XL) (15)

It is dangerous to combine phentermine and beta blockers because the weight loss medication counteracts the blood pressure medicine´s effects. Plus, combining these two substances puts patients at risk for increased blood pressure and slowed heart rate/heart block related to unopposed alpha-adrenergic stimulation (7).

5. Diabetes Medications

Phentermine may significantly affect blood glucose control. This medication is not appropriate for all people with diabetes.

The stimulant increases circulation of “fight or flight” hormones, which boosts glucose production by the liver and may decrease glucose uptake by cells (7). At the same time, lifestyle modifications for weight loss – like restricting calories or increasing activity – can lower blood sugar (16).

Both types of variations may affect your need for diabetes medications.

Tell your doctor about all diabetes medications (both oral and injectable) and monitor your blood sugar closely before and during treatment with phentermine.

Given the increased risk, if you have diabetes it is important to speak frankly with your prescribing physician about your recent blood sugar control and the appropriateness of phentermine for weight loss in your specific case.

Tell your doctor and pharmacist about ALL recent medications and supplements, even if they are not listed above.

This is not a complete list of medications that interact with phentermine weight loss pills.

Lifestyle-Related Phentermine Warnings

Do not combine phentermine and alcohol

In addition to the long list of phentermine contraindications related to potential drug interactions, phentermine weight loss pills can also prove problematic when combined with certain behaviors.

Phentermine and Alcohol

Do not drink alcohol while taking phentermine.Phentermine functions as a central nervous system stimulant, while alcohol acts as a depressant. Combining the two substances increases risk for cardiovascular and central nervous system side effects, such as:

  • Increased heart rate
  • Increased blood pressure
  • Chest pain
  • Dizziness
  • Drowsiness
  • Depression
  • Trouble concentrating

Note: Cannabis (marijuana) can also increase dizziness and drowsiness. Talk to your prescribing doctor if you use marijuana.


Eliminate or minimize caffeine consumption while taking phentermine.

Is it suitable for anyone?

One has to be 16 year and over.
Breastfeeding and Pregnant women are 100% advised to avoid.
Check to review the above pre-existing conditions and contraindications.(All info on Contraindication etc taken from the original Phentermine manufacturer.)

Adverse Reactions

Phentermine is a highly-effective weight loss medication, but it also has a long list of potential side effects.
Serious reactions to phentermine, which may be symptoms of a potentially-fatal heart or lung problem, include (5,6):

  • Chest pain
  • Irregular (fluttering) or pounding heart rate
  • Shortness of breath
  • Light headedness or fainting
  • Swelling of the ankles, legs or feet
  • Stroke-like symptoms, such as slurred speech or one-sided weakness
  • Extreme happiness or sadness

However, most people experience only side effects. The most-commonly reported reactions are dry mouth, insomnia, constipation and headache (7).
Most patients report fewer side effects as the treatment progresses. Lower dose pills or alternate schedules can also help alleviate the bothersome reactions faster.

Is it suitable for anyone?

Most countries where it is provided, prescribe only for patients 16 and over.Pregnant or breastfeeding mother are advised to avoid.
Not recommended for anyone who suffers from pre-existing medical conditions, such as heart disease, thyroid problems, glaucoma, has mental issues or a history of drug abuse.
