Phentermine is a drug used for weight loss in obese or overweight people. It is typically prescribed as part of a weight loss plan that includes exercise, behaviour modification, and calorie restriction. Phentermine is classified as a Schedule IV controlled substance by the DEA due to its potential for misuse and dependence. It is not a narcotic, as narcotics act on opioid receptors to treat moderate to severe pain, while phentermine is a stimulant that decreases appetite by acting on the central nervous system. Despite its effectiveness in weight loss, phentermine has various side effects, including increased heart rate, high blood pressure, and restlessness. It can also cause rare but serious side effects such as heart valve problems and increased blood pressure in the lungs. Due to these risks, it is important to consult a doctor before taking phentermine and to follow the prescribed dosage carefully.

What You'll Learn
Phentermine is not a narcotic
Phentermine is a prescription medication used to aid weight loss in people with obesity or those who are overweight with other health conditions, such as high blood pressure, diabetes, or high cholesterol. It is typically prescribed as a short-term treatment option, usually for 12 weeks or less, and is meant to be used in conjunction with a reduced-calorie diet, exercise, and behavioural modifications.
Phentermine is classified as a Schedule IV controlled substance by the DEA, which means it has a lower potential for abuse compared to Schedule III substances. While it is a controlled substance, phentermine is not a narcotic. Narcotics act on opioid receptors and are used to treat moderate to severe pain. On the other hand, phentermine is a stimulant that increases heart rate and blood pressure while decreasing appetite.
Phentermine is similar to amphetamines in its chemical structure and can even lead to false-positive urine tests for amphetamines. Its stimulant properties can cause side effects such as increased heart rate, high blood pressure, restlessness, and decreased appetite. In rare cases, phentermine may cause serious side effects like heart valve problems and increased blood pressure in the lungs (pulmonary arterial hypertension), which can be life-threatening.
Due to the potential for misuse and the development of tolerance, phentermine should be taken exactly as prescribed by a doctor. It is important to be cautious when taking phentermine concurrently with other medications, as many drugs can interact with it, including prescription medications, over-the-counter medicines, vitamins, and herbal products. Additionally, phentermine is not suitable for everyone, and individuals with specific medical conditions, such as heart disease, glaucoma, or a history of drug abuse, should avoid taking it.

Phentermine is a controlled substance
Phentermine is a Schedule IV controlled substance. This classification is given to drugs that can be misused and cause dependence. Phentermine is similar to amphetamines and stimulates the central nervous system, increasing heart rate and blood pressure, and reducing appetite. It is used to speed up weight loss in overweight people, especially those with risk factors such as high blood pressure, high cholesterol, or diabetes.
Phentermine is typically prescribed as a short-term treatment for people with a body mass index (BMI) of 30 kg/m2 or greater. It may also be prescribed to people with a BMI of 27 kg/m2 or above who have other risk factors. The drug is usually taken for 12 weeks or less and its effects depend on the dosage, diet, and exercise levels. It is meant to be used in conjunction with a reduced-calorie diet and exercise plan.
Phentermine can cause serious side effects, including heart valve problems and increased blood pressure in the lungs, which can be fatal. It may also cause allergic reactions, changes in alertness or coordination, and tolerance, where the body gets used to the medicine and it seems to stop working. Misusing phentermine can lead to serious side effects like hallucinations or psychotic-like behaviors. It is not suitable for pregnant or breastfeeding women, and those with certain medical conditions, such as heart disease, glaucoma, or high blood pressure, should not take it without consulting a doctor.

Phentermine's side effects
Phentermine is a prescription weight-loss pill that can help reduce appetite and increase metabolism. While it can be effective for short-term weight loss when used alongside a reduced-calorie diet and exercise, it does come with a range of side effects that users should be aware of.
Common side effects of phentermine include:
- Increased heart rate and blood pressure: This is a potential concern for people with pre-existing heart conditions or high blood pressure. It is important to monitor your heart rate and blood pressure regularly while taking phentermine and to consult your doctor if you notice any abnormalities.
- Insomnia: Phentermine can interfere with sleep patterns, causing insomnia or difficulty falling or staying asleep. This side effect may improve over time as your body adjusts to the medication.
- Restlessness: Users may experience restlessness, nervousness, or irritability while taking phentermine. These side effects can sometimes be mitigated by reducing the dosage or taking the medication earlier in the day.
- Dry mouth: This side effect is relatively common and can often be relieved by chewing sugar-free gum, sucking on ice chips, or using a saliva substitute.
- Digestive issues: Phentermine may cause stomach upset, diarrhea, or constipation in some individuals. These side effects usually improve with proper diet and adequate fluid intake.
More serious, but less common, side effects include:
- Pulmonary hypertension: This is a rare but serious side effect that can occur with long-term use of phentermine. It involves high blood pressure in the lungs and can lead to shortness of breath, dizziness, and, in severe cases, heart failure.
- Valvular heart disease: There is a small risk of valvular heart disease associated with phentermine use, which can lead to irregular heart rhythms and, in rare cases, heart failure.
- Addiction and tolerance: Phentermine has the potential to be habit-forming, and prolonged use may lead to dependence and withdrawal symptoms if stopped abruptly. It is important to use this medication only as directed and under the supervision of a doctor.
It is important to note that the safety and effectiveness of phentermine have only been established for short-term use, usually defined as up to 12 weeks. Using phentermine for longer periods increases the risk of serious side effects and may decrease the effectiveness of the drug.

Phentermine's interactions with other medications
Phentermine is a stimulant medication similar to amphetamines. It is prescribed for short-term use alongside diet and exercise for weight loss in certain adults who are overweight or obese. It is important to note that phentermine has the potential to interact with various substances, including medications, supplements, alcohol, and food.
There are 196 drugs known to interact with phentermine, with 43 major interactions, 151 moderate interactions, and 2 minor interactions. It is imperative that you inform your doctor and pharmacist about any prescription, over-the-counter, or other medications you take, including supplements, herbs, and vitamins. This information will help prevent potential interactions.
Phentermine interacts with certain diabetes drugs, and your doctor may need to monitor your blood sugars more closely and adjust your diabetes medication accordingly. Additionally, phentermine interacts with other stimulant medications, increasing the risk of serious side effects such as high blood pressure, rapid heart rate, anxiety, insomnia, and, in severe cases, heart attack or stroke.
Phentermine also interacts with certain drugs that impact the heart, blood pressure, or nervous system. Antihypertensives, antipsychotics, and antidepressants, including bupropion, monoamine oxidase inhibitors (MAOIs), and selective serotonin reuptake inhibitors (SSRIs), are among the drugs that interact with phentermine. These interactions can lead to hypertension, seizures, or serotonin syndrome, which can cause life-threatening changes to body temperature regulation and the neurological system.
Furthermore, phentermine can interact with alcohol. Although there are no known interactions, drinking alcohol while taking phentermine may increase the risk of certain side effects, such as dizziness. Doctors may advise limiting alcohol consumption during phentermine treatment.

Phentermine and pregnancy
Phentermine is a drug used to speed up weight loss in overweight people. It is used together with diet and exercise to treat obesity, especially in people with risk factors such as high blood pressure, high cholesterol, or diabetes. It is not recommended for use by anyone who is pregnant, trying to become pregnant, or breastfeeding.
Phentermine is a Schedule IV controlled substance, classified as an anorectic. It works by reducing appetite, thereby aiding weight loss. It is typically prescribed for short-term treatment in people with a body mass index (BMI) of 30 kg/m2 or greater. It may also be prescribed to people with a BMI of 27 kg/m2 or greater if they have other risk factors.
Pregnant women should not use phentermine. Weight loss during pregnancy can harm an unborn baby, even if the mother is overweight. If you become pregnant while taking phentermine, you must stop taking the medication and consult your doctor immediately. Phentermine may increase the risk of a birth defect called cleft lip or cleft palate in the newborn. This defect can develop very early in the pregnancy, even before a woman knows she is pregnant. Therefore, it is recommended that women use birth control to prevent pregnancy during their treatment with phentermine. A pregnancy test is mandatory before beginning treatment and once every month during treatment.
Phentermine is also not suitable for women who are breastfeeding. It is important to tell your doctor if you are pregnant or plan to become pregnant, so they can advise accordingly and prescribe alternative treatments if necessary.
