Phentermine in Texas: Benefits, Uses, and What to Know
GLP-1 medications like semaglutide (Wegovy, Ozempic, Wegovy HD, Wegovy pill) and tirzepatide (Zepbound, Mounjaro) have received a lot of attention. However, there are other, older alternatives that don't require an injection. Phentermine is one such drug.
Phentermine (Adipex-P, Lomaira) was FDA-approved for weight loss in 1959. It has proven effective for short-term use when combined with exercise and a low-calorie diet.
But how does phentermine work? Is it safe for weight loss? And how can you get it in Texas? NP2GO is now licensed to prescribe phentermine in Texas. In this guide, we'll explore how phentermine works, its potential benefits for weight loss and health, and how you can get it through NP2GO in Texas.
What Is Phentermine?
Phentermine is an oral weight-loss medication that works by decreasing appetite. It's approved for short-term use of up to 12 weeks for people over 16 years old. However, some medical professionals might order it for extended use.
Phentermine can be used alone under the brand names Adipex-P, Lomaira, and Suprenza. It can be found in weight-loss combination drugs like Qsymia, which combines phentermine with topiramate. The combination medication is approved for long-term use.
This oral weight loss medication is a stimulant, and you can get it if you have a prescription. It is classified as a controlled substance due to the possibility of dependence.
Your healthcare professional may prescribe phentermine if your body mass index (BMI) is 30 or higher, which is considered obesity. You may also be prescribed phentermine if your BMI is greater than or equal to 27 and you have at least one weight-related problem, such as high blood pressure, high cholesterol, or type 2 diabetes.
How Does Phentermine Work for Weight Loss?
Phentermine belongs to a class of medications known as anorectics, or appetite suppressants.
Using phentermine reduces your appetite, helping you consume fewer calories. Eating less can cause an energy deficit, helping you burn more calories than you consume, which eventually results in weight loss.
While the precise mechanism by which phentermine decreases appetite remains unknown, it is believed to act by increasing neurotransmitter levels in your brain.
Your body uses neurotransmitters, such as dopamine, serotonin, and norepinephrine, as chemical messengers.
When your levels of these three hormones increase, you feel less hungry.
Phentermine works best when used in conjunction with a healthy diet and frequent exercise. It may not be as effective for you if you do not change your lifestyle while taking it. Additionally, you might be more likely to gain weight again once you stop taking this medication.
Is Phentermine Effective for Weight Loss?
Several clinical trials have proven that Phentermine can help with significant weight loss.
Even though the FDA only approved phentermine for short-term use of less than 12 weeks, healthcare practitioners frequently prescribe it off-label for longer use.
They may prescribe it intermittently, which means you will stop taking it for a certain period of time before starting it again.
Some earlier research has reported that people taking phentermine may lose around 3% of their initial body weight after three months and approximately 5–7% after six months. However, some people may lose more, while others may lose less.
For example, a person who weighs 200 pounds could lose approximately 10–14 pounds with a 5–7% reduction in body weight.
But not everyone responds to this drug in the same way. A doctor might advise stopping the drug if, after 3 months of use, you haven't reduced your weight.
While phentermine has been shown to be useful for weight loss, it may be even more effective when combined with topiramate.
Topiramate is a medication that has been used alone to treat seizures, but it also has the potential to suppress appetite.
Topiramate and phentermine, when combined, are sold under the brand name Qsymia. The FDA approved it in 2012 for use in combination with healthy lifestyle choices, including increased physical activity and a low-calorie diet.
The combination of phentermine and topiramate was associated with the highest likelihood of losing at least 5% of starting body weight.
Furthermore, according to a recent study, those who took a drug containing phentermine and topiramate lost an average of 16 pounds (7.3 kg) compared with a placebo.
What’s the Typical Phentermine Dosage, and How Should I Take It?
Take phentermine exactly as prescribed by your healthcare provider. Your dose and dosing schedule will depend on the specific formulation you are prescribed and your individual treatment plan. Always follow the instructions on your prescription label, and ask your provider or pharmacist if you have questions about how to take it.
Phentermine doses range from 15 mg to 37.5 mg daily. However, the typical dosage for Lomaira is 8 mg (1 tablet) and is taken 3 times a day before meals. Regardless of which form of phentermine you take, here’s how you should take it:
Take it at the prescribed time. Phentermine is commonly taken in the morning, either before breakfast or 1 to 2 hours after breakfast. Taking it later in the day may cause difficulty sleeping or insomnia.
Follow your prescribed dose. Some patients may be prescribed phentermine more than once daily, but you should never change the frequency or amount without talking with your provider.
Do not take more than prescribed. Taking a higher dose will not necessarily lead to greater weight loss and can increase the risk of serious side effects.
Avoid alcohol while taking phentermine. Alcohol may worsen certain side effects and impair judgment.
Don't combine phentermine with other weight-loss medications unless your provider specifically tells you to do so. Your provider should review all medications and supplements you take before starting treatment.
Store phentermine properly. Keep it at room temperature and away from excessive heat and moisture. Store it securely and keep the container tightly closed when not in use.
If you miss a dose, follow the instructions provided by your healthcare provider or pharmacist. Do not take extra medication to make up for a missed dose.
Because phentermine is a prescription medication that can cause stimulant-related side effects, your NP2GO provider will give you personalized instructions based on your prescription and health needs.
Who May Be a Candidate for Phentermine?
Phentermine is indicated as a short-term addition to exercise, behavioral changes, and a reduced-calorie diet for adults with an initial body mass index (BMI) of 30 kg/m² or higher, or 27 kg/m² or higher when certain weight-related risk factors are present, such as controlled high blood pressure, diabetes, or high cholesterol.
However, BMI isn't a perfect tool and may not be a reliable indicator of your health. Your medical team may still decide to prescribe phentermine, even if you don't fit into one of these approved categories. But you shouldn’t use phentermine without the guidance of a healthcare expert.
Who should not take phentermine?
Phentermine may not be a good option for you if you have certain health conditions, such as:
Heart disease
Uncontrolled hyperthyroidism
Uncontrolled hypertension
Glaucoma
Breastfeeding or pregnant women
Planning to get pregnant
Prone to agitation
Taking a monoamine oxidase inhibitor (MAOI) within the past 14 days
History of drug abuse
What Are the Side Effects of Phentermine?
Some of the common side effects that may occur while taking phentermine include:
Dry mouth
Unpleasant taste
Constipation
Diarrhea
Restlessness
Dizziness
Headache
Difficulty sleeping or insomnia
Increased heart rate
Increased blood pressure
These effects may be more noticeable when starting treatment or if the dose is increased.
Serious side effects
Although uncommon, some serious adverse reactions have been associated with phentermine. These include increases in blood pressure, rapid heartbeat, ischemic events, and rare pulmonary or heart valve complications.
Contact your healthcare provider if you experience concerning symptoms such as chest pain, shortness of breath, fainting, severe or persistent headache, or a rapid or irregular heartbeat.
How Long Can You Take Phentermine?
Your healthcare provider will help you determine how long to take phentermine based on your medical history and how well it’s working for you.
Phentermine is officially approved by the FDA for short-term use of up to 12 weeks (3 months). This is because, when it was first approved, there was no evidence that it was safe to use for an extended period.
However, more recent research indicates that using phentermine for longer than 3 months is safe and may even help people lose more weight. Findings from an ongoing study of the long-term safety and effectiveness of phentermine are expected to be released early in 2027.

2. Discuss your health and weight-loss goals.
During your consultation, your provider will review your health history, weight-loss goals, current medications, and other factors that may affect your eligibility for phentermine. NP2GO's weight-loss approach is individualized rather than using the same treatment for every patient.
Be prepared to provide information about any medical conditions, prescription medications, over-the-counter products, and supplements you currently use.
3. Determine whether phentermine is appropriate
Phentermine is not suitable for everyone. Your provider will consider your overall health, medical history, potential contraindications, and weight-management needs before deciding whether it is an appropriate treatment option.
If phentermine is not the right choice for you, your provider can discuss other weight-management approaches that may better fit your needs.
4. Receive your personalized treatment plan
If you are an eligible candidate, your provider will prescribe phentermine based on your individual treatment needs and provide instructions for safe use.
Your treatment plan may also include recommendations for nutrition, physical activity, and other lifestyle changes.
5. Follow-up
Weight management doesn't end when you receive a prescription. Follow-up care allows your provider to monitor your progress, discuss any side effects, and make adjustments to your treatment plan when needed.
Phentermine Alternatives
While phentermine is normally prescribed for weight loss, it is indicated only for short-term use. While some healthcare providers prescribe it long-term, it may not be a good option for everyone to use long-term. It may also not be good for you because of contraindications. In this case, if your healthcare provider considers it necessary for you to use weight loss medication, phentermine alternatives may be considered.
Qsymia may be a close alternative to phentermine. GLP-1 receptor agonists, like Wegovy and Saxenda, are other common medications that have been proven effective for weight loss.
GLP-1 and GIP receptor agonists, such as Zepbound, are even more powerful alternatives.
FAQs About Phentermine in Texas
Is phentermine good for weight loss?
Phentermine can support weight loss in eligible adults by reducing appetite and helping decrease calorie intake. It works best as part of a comprehensive plan that includes a reduced-calorie diet, regular physical activity, and behavioral changes. Individual results vary, so your healthcare provider can determine whether phentermine is appropriate for your weight-loss goals and health needs.
Can I get phentermine online in Texas?
Yes, eligible patients in Texas may be able to receive phentermine through a licensed telehealth provider after a medical evaluation. NP2GO is now licensed to prescribe phentermine in Texas. During your virtual consultation, a provider can review your health history, medications, and weight-loss goals to determine whether phentermine is an appropriate treatment option.
Does phentermine suppress appetite?
Yes. Phentermine mainly works as an appetite suppressant by affecting the central nervous system. Reducing feelings of hunger may help you eat smaller portions and maintain the calorie deficit needed for weight loss. However, phentermine does not directly burn fat and should be combined with healthy eating and physical activity for comprehensive weight management.
Is phentermine safe?
Phentermine can be safe and effective for eligible patients when prescribed and monitored by a qualified healthcare provider. However, it is not appropriate for everyone and can cause side effects, including increased heart rate, high blood pressure, nervousness, and insomnia. Your provider should review your medical history and medications before determining whether phentermine is suitable for you.
Can you take phentermine long-term?
Phentermine is FDA-approved for short-term use as an addition to diet, exercise, and behavioral changes. Some healthcare professionals may prescribe it for longer than the FDA-approved duration when medically appropriate, which is considered off-label use. Long-term treatment should never be self-directed. Your provider should regularly evaluate the medication's effectiveness, safety, and ongoing suitability.
Is phentermine better than Ozempic or Wegovy for weight loss?
Not necessarily. Phentermine and GLP-1 medications, such as Ozempic and Wegovy, work differently and have distinct approved uses, benefits, and risks. The best option depends on your health history, weight-loss goals, medications, and individual response. A qualified provider can help determine which treatment may be most appropriate for your specific circumstances.
Do you need a prescription for phentermine in Texas?
Yes. Phentermine is a prescription medication and cannot legally be obtained without a prescription from an authorized healthcare provider. In Texas, eligible patients can discuss phentermine with an NP2GO provider through a medical consultation. If appropriate, the provider can prescribe it as part of an individualized, medically supervised weight-management plan.
