Phentermine 37.5 mg – Order Online Without Prescription

General Information
One of the most popular diet pills that have been scrutinized for its intense, widespread side effects is phentermine. Numerous consumer warnings have been generated to prevent the use of this diet pill as a weight loss method. When used as an OTC diet pill, the side effects of this drug are taken less seriously. This trend is concerning, due to the health concerns that phentermine can generate on a short- and long-term basis. Phentermine 37.5 mg should be taken as a last resort, but it is best to disregard usage of this drug entirely.

In 1959, Phentermine resin became available in the U.S. and was followed by the introduction of Phentermine Hydrochloride in the 1970s. Previously available under the name Fastin, which was removed from the market in 1998, Phentermine Hydrochloride became increasingly popular in 1973 when it was combined with Fenfluramine. Known as Fen-Phen, this powerful diet cocktail resulted in numerous cases of heart valve disease and abnormal heart valve findings.

Mechanism of Action
Along with a reduced-calorie diet and exercise, phentermine is a legitimate method of weight loss for those who have a severe risk of developing obesity-related health conditions, such as high blood pressure, diabetes, and heart disease. Though it is not known how this medication helps patients lose weight, doctors do know that it is an appetite suppressant that belongs to a class of drugs known as sympathomimetic amines. This dangerous drug class is similar in prototype to well-known amphetamines, which also aide in weight loss.

Dosage and Administration
Phentermine 37.5 is usually prescribed and taken in a oral manner. Dissolving tablets or sustained-release capsules are common. This diet pill should be taken in the lowest effective dosage or as recommended by a physician. Ingesting this medication a few hours after eating breakfast seems to produce adequate results for most patients.

Generally available as Phentermine 37.5 mg hydrochloride or hcl, these capsules also include inactive ingredients: monohydrate, lactose, pregelatinized starch, magnesium stearate, colloidal silicon dioxide, and microcrystalline cellulose. The pharmacodynamics of this medication is similar to those of amphetamines in the nature that they utilize the central nervous system, which can lead to an increase in blood pressure. However, elevated blood pressure is not the sole side effect of this medication.

Adverse Effects

In essence, phentermine 37.5 has displayed a large number of serious side effects, which makes this drug dangerous on many levels.

-CNS (Central Nervous System): Restlessness, dizziness, insomnia, headache, psychosis.
-Gastrointestinal: Oral dryness, constipation, diarrhea, unpleasant taste.
-Endocrine: Impotence and changes in libido.
The aforementioned side effects are only a select few of the known characteristics of this drug. As a result of the numerous side effects of this medication and the lack of knowledge pertaining to its interaction with other medications, it is merely recommended for short-term use.

In addition to these common side effects, phentermine 37.5 may also cause adverse reactions when used in conjunction with MAOIs (Monoamine Oxidase Inhibitors, Alcohol, Insulin and Oral Hypoglycemic Drugs, and Adrenergic Neuron Blocking Drugs. Phentermine may also illicit teratogenic effects on human fetuses, which makes it unsafe to use before and during pregnancy.

Brand Name Variations
Phentermine 37.5 is available not just under the brand name, but under other dietary aliases, such as Adipex-P, Oby Cap, Suprenza, T-Diet, and Zantryl. These are common OTC terms that most patients will come across when using phentermine as a weight loss tool without a prescription.
