Terfamex is a prescription drug that helps to suppress appetite and stimulate the central nervous system to increase heart rate and blood pressure. These inadvertently increases the metabolism and when combined with exercises, helps you lose weight faster.

In this article, we will discuss what Terfamex is, how it works, the dangers that are associated with using Terfamex alone and with other medications. We will also answer questions such as Who should use Terfamex? How long does it take Terfamex to work? Where can I buy Terfamex?

What is Terfamex

Terfamex is an anorectic – a drug that suppresses appetite for reduced food consumption leading to loss of weight – mostly prescribed for obese and overweight individuals. It contains Phentermine hydrochloride, a compound that bears similarity to amphetamine – also used to treat obesity.

Terfamex is usually prescribed for use in individuals who are overweight or obese and are willing to lose some pounds but have factors that make it complicated to achieve without medication. This set of people usually have one or more of these conditions; diabetes, high cholesterol level, or high blood pressure.

When Terfamex is combined with a well-structured diet plan and exercises, it usually produces tremendous results and helps obese and overweight people lose weight for a healthier life. Although it is effective, it is usually discontinued after some weeks to avoid or stop some of the side effects that come with its use. Patients who use Terfamex are closely monitored by their doctors.

How does Terfamex work?

As an anorectic, it works with the nervous system, that is, the brain and other concerned nerves. Terfamex does its magic by making the nerves concerned with alerting the brain of an empty stomach less effective. Also, it reduces the production of the hunger hormone, Ghrelin. Terfamex suppresses appetite but does not eliminate the need for food by the body.

The human body keeps itself nourished by sending a signal to the hypothalamus – a part of the brain of that the stomach is empty. The hypothalamus, in turn, triggers the production of Ghrelin – the hunger and appetite hormone – which helps you to know you should eat. However, feeling hungry does not directly translate to having an appetite for food.

Terfamex works by stopping the neural signals from the gastrointestinal tract from transmitting its messages to the hypothalamus, consequently leading to little or no production of the hunger and appetite hormone.

Terfamex Dosage and Administration

Terfamex is currently available in two forms, as a capsule and as an orally disintegrating tablet (ODT).

Depending on many factors that will be considered by your doctor, a Terfamex prescription can come in any of these three dosages.

  • Terfamex 15 milligrammes (mg)

This is the lowest dose of Terfamex available in any pharmacy. It is available in both capsule and ODT forms.

This dose of Terfamex is usually taken twice daily, preferably one in the morning – before breakfast – and the next dose some hours after the first.

  • Terfamex 30 milligrammes (mg)

This dose of Terfamex is available only in capsule form. With its concentration of Phentermine HCL twice that of 15 mg, it is taken once a day, usually in the morning and before breakfast.

  • Terfamex 37.5 milligrammes (mg)

The highest Terfamex dosage out there. It is available in the ODT form and requires use only once daily. It can be used with or without water since it will dissolve in the mouth. It is suitable for individuals who have problems swallowing capsules.

It is important to note that Terfamex is administered orally only.

It is also important to note that due to the addictive nature of the drug, it is usually discontinued after about 12 weeks of use. If your treatment needs to exceed 3 months, your doctor will design a treatment plan that involves breaks after every 12 weeks of use.

Side Effects of Terfamex

Terfamex use comes with some side effects. Some are not serious and are no cause for medical emergencies. However, some side effects require that you contact your doctor immediately.

Subtle side effects of Terfamex

These side effects are usually mild and will disappear after a couple of days. However, if they persist, visit your pharmacist or doctor.

Serious Side Effects of Terfamex

These severe symptoms need to be taken to the attention of the doctor as soon as they start.

Interaction with Other Medications

Terfamex contains Phentermine HCL, a compound that can act as a stimulant. It does not always work well if combined with some other medications and substances. Therefore, inform your doctor of any medication you are on to help them make an informed prescription.

Some substances and medications that should not be combined with Terfamex include:

  • Antidepressants

Medications that inhibit the production of biochemicals such as monoamine oxidase – Rasagiline, Isocarboxazid, Tranylcypromine – and serotonin reuptake inhibitors – Nefazdone, Fluoxetine, Citalopram, and many more, should be avoided when using Terfamex.

  • Blood Pressure Regulation medications

Medications for individuals that need their blood pressure to be regulated such as guanethidine should also be discontinued if you are to use Terfamex.

  • Other weight loss medications

  • Alcohol

The use of alcohol should stop during the period of this medication use. The effect of alcohol counteracts the effect of Terfamex. While Terfamex is a medication that stimulates and increases energy level while it suppresses appetite, alcohol reduces energy level. The contradiction might lead to a heart pressure crisis.

  • Insulin and other diabetes medications

Terfamex is a medication that is strictly bought with a prescription. It is used for weight loss in obese and overweight patients that have other medical conditions such as diabetes and heart problems that may make weight loss otherwise difficult.
