Formula Information

A small arrow pointing down

Phentermine HCl 37.5 mg/ml Oral Liquid is a specially compounded medication designed for oral use, providing an alternative to traditional tablet or capsule forms of phentermine. This liquid formulation is particularly beneficial for patients who have difficulty swallowing pills, such as those in pediatric or geriatric populations, or for individuals with dysphagia or other conditions that impair the ability to swallow solid dosage forms. The liquid form allows for precise dosing and can be easier to ingest, ensuring that patients receive the exact amount of medication required for their treatment.

Phentermine is a sympathomimetic amine anorectic agent and is typically used as a short-term adjunct in the management of exogenous obesity. It works by suppressing appetite and possibly increasing energy expenditure, thereby aiding in weight loss in obese patients when used in conjunction with a doctor-approved exercise, behavior change, and reduced-calorie diet program. Phentermine is thought to decrease appetite by acting on a part of the brain that controls appetite and satiety, known as the hypothalamus. It releases norepinephrine, a neurotransmitter, which triggers a fight-or-flight response, reducing hunger signals.

It is important for both patients and prescribers to understand that phentermine should be used as part of a comprehensive weight loss plan and is not intended for long-term use. The effectiveness of phentermine for long-term use, that is, more than a few weeks, has not been established, and its use should be accompanied by lifestyle changes for sustainable weight management. Patients should also be aware of potential side effects, which can include increased heart rate, elevated blood pressure, dizziness, restlessness, insomnia, and dry mouth. Due to its chemical similarity to amphetamines, phentermine has the potential for abuse and dependence and should be prescribed and used with caution.

As compounding pharmacists at Bayview Pharmacy, we ensure that each batch of Phentermine HCl 37.5 mg/ml Oral Liquid is prepared to the highest standards of quality and safety. We can also customize the formulation to meet specific patient needs, such as flavoring the medication to improve palatability. It is crucial that this medication is stored properly and that the prescribed dosage is followed accurately. If you have any questions or require further information about this formulation, please do not hesitate to reach out to us. We are here to support both patients and healthcare providers in the safe and effective use of compounded medications.

Drug Interactions

A small arrow pointing down

Phentermine HCl is a sympathomimetic amine anorectic indicated as a short-term adjunct in a regimen of weight reduction based on exercise, behavioral modification, and caloric restriction in the management of exogenous obesity for patients with an initial body mass index (BMI) of 30 kg/m² or higher, or 27 kg/m² or higher in the presence of other risk factors such as controlled hypertension, diabetes, or hyperlipidemia. The pharmacological action of phentermine is similar to that of amphetamines, and it is classified as a Schedule IV controlled substance due to its potential for abuse and dependence.

When considering the use of phentermine HCl 37.5 mg/ml oral liquid, it is crucial to be aware of potential drug interactions that may affect the efficacy of the medication or increase the risk of adverse effects. Phentermine should not be used concomitantly with other central nervous system stimulants or weight loss medications, including prescribed drugs, over-the-counter preparations, and herbal products, to avoid the risk of additive effects and possible cardiovascular complications.

Phentermine may interact with monoamine oxidase inhibitors (MAOIs). Using phentermine with MAOIs can result in a hypertensive crisis due to additive effects on the release of norepinephrine. Therefore, phentermine should not be administered during or within 14 days following the administration of MAOIs.

Caution is advised when phentermine is co-administered with other drugs that affect the cardiovascular system, such as antihypertensive medications and drugs that alter cardiac rhythm. The effects of phentermine on blood pressure and heart rate may necessitate adjustments in the dosing of these concurrent medications.

Phentermine may decrease the hypotensive effect of adrenergic neuron blocking drugs. Patients taking these medications should be monitored closely for a potential decrease in their antihypertensive efficacy.

Concomitant use of alcohol with phentermine may result in an adverse drug reaction, as alcohol can potentiate the effects of phentermine and increase the risk of cardiovascular side effects such as increased heart rate and elevated blood pressure.

Phentermine should be used with caution in patients receiving medications for diabetes, including insulin and oral hypoglycemic agents, as weight loss can alter insulin requirements. Close monitoring of blood glucose is recommended when initiating or discontinuing phentermine in diabetic patients.

Patients should be advised to inform their healthcare provider of all medications they are currently taking, including prescription and nonprescription drugs, dietary supplements, and herbal products, before starting phentermine therapy. Additionally, patients should be counseled to avoid new medications without first consulting their healthcare provider.

It is important to note that this is not an exhaustive list of all potential interactions with phentermine. Healthcare providers should consult additional sources and use clinical judgment when prescribing phentermine HCl 37.5 mg/ml oral liquid. If you have any questions or concerns regarding drug interactions with phentermine, please reach out to us at Bayview Pharmacy for further assistance.

How Does it Work

A small arrow pointing down

Phentermine HCl 37.5 mg/ml Oral Liquid is a specially crafted medication designed for oral use, providing an alternative to tablet or capsule forms of phentermine. This liquid formulation is particularly beneficial for patients who have difficulty swallowing pills, such as those in pediatric or geriatric populations, or for individuals with dysphagia or other conditions affecting the ability to swallow solid dosage forms. The liquid form ensures that the active ingredient, phentermine hydrochloride, is delivered in a precise, measured dose, which is crucial for maintaining the efficacy and safety of the medication.

Phentermine is a sympathomimetic amine anorectic agent, which means it mimics the action of the sympathetic nervous system, specifically norepinephrine. It stimulates the release of norepinephrine in the brain, which in turn suppresses appetite and increases energy expenditure by its action on the hypothalamus. This dual action helps reduce caloric intake and can lead to weight loss when used in conjunction with a doctor-approved exercise, behavior change, and reduced-calorie diet program. It is typically prescribed for short-term management of obesity in patients with a body mass index (BMI) greater than or equal to 30 kg/m², or greater than or equal to 27 kg/m² in the presence of other risk factors such as hypertension, diabetes, or dyslipidemia.

The oral liquid formulation of phentermine HCl allows for flexible dosing, which can be adjusted according to the specific needs of the patient. The medication is usually taken once daily, either before breakfast or 1 to 2 hours after breakfast. The liquid form can be particularly useful for titrating doses in sensitive patients or when initiating therapy to minimize side effects and optimize therapeutic response. It is important to note that the use of phentermine should be limited to a few weeks, as it can lead to dependence and its efficacy at promoting weight loss decreases after a few weeks of continuous use.

As with any medication, phentermine HCl oral liquid should be used under the supervision of a healthcare provider. It is contraindicated in patients with cardiovascular disease, hyperthyroidism, glaucoma, a history of drug abuse, or in those taking monoamine oxidase inhibitors (MAOIs). Side effects may include increased heart rate, elevated blood pressure, insomnia, nervousness, and constipation. Patients and prescribers should monitor for signs of adverse reactions and adjust the treatment regimen accordingly.

Other Uses

A small arrow pointing down

Phentermine HCl, primarily indicated for weight loss, acts as an appetite suppressant and is typically prescribed as part of an overall weight reduction regimen that includes diet, exercise, and behavior modification. However, since the main mechanism of phentermine is to increase the release of neurotransmitters to suppress appetite, there may be potential off-label uses as well, although these are not extensively documented or officially approved. For instance, some prescribers may consider deploying phentermine in the management of attention deficit hyperactivity disorder (ADHD) due to its structurally similarity to amphetamines, which are commonly used to treat ADHD. Nevertheless, caution is advised since the use of phentermine for ADHD is not substantiated by robust clinical trials.

Further potential, yet not standard, applications of this liquid formulation may include situations requiring neurostimulation in patients with conditions that could benefit from enhanced central nervous system activity—such as certain forms of depression or narcolepsy—however, due to its side effect profile and potential for abuse, the utilization of phentermine for these purposes is uncommon and should be closely monitored. It's imperative to note that phentermine is a Schedule IV controlled substance, due to its potential for abuse and dependence, which significantly limits its use outside of its approved indication for obesity with associated medical risk factors.

The liquid formulation, specifically, could provide a unique advantage for dose titration in a controlled manner, allowing for more precise dosing than may be possible with a tablet or capsule, under the guidance of a healthcare provider. This could be advantageous when initiating therapy to establish an effective and well-tolerated dose. Additionally, the liquid formulation provides a valuable alternative for patients who have difficulties swallowing solid dosage forms or for whom a customized dose is necessary. Nevertheless, all uses of phentermine, including off-label ones, should be approached with caution and under strict medical supervision to minimize the risks of adverse effects and to ensure safety. If you have any questions or need guidance with regard to the pharmacological aspects or potential other uses of Phentermine HCl 37.5 mg/ml Oral Liquid, feel free to reach out to us at Bayview Pharmacy. We are ready to assist and provide the necessary expertise to ensure optimal therapeutic outcomes for our patients.
