What is Phentermine?
Phentermine is a drug primary used as an appetite suppressant, typically prescribed for individuals being at increased medical risk because of their weight.
A bit history about Phentermine:
Phentermine is an anti-obesity drug, an appetite suppressing drug. Phentermine first received approval from the FDA in 1959. Phentermine hydrochloride became available in the early 1970.
Phentermine was one of the two drugs known as the Fen-phen ( Fenfluramine and phentermine) medication. But Fenfluramine was withdrawn from the US market in September 1997 after an FDA request.
Fen-phen retrieval from the market was as a result of reports of valvular heart disease in women treated for obesity with a combination of fenfluramine and phentermine. However, Phentermine remains available by itself in most countries, including the U.S.
How it works:
Phentermine is a synthetic stimulant. It acts on our Central Nervous System . It stimulates our nerve cells to release neurotransmitters which are a group of particular chemical compound including adrenalin. The neurotransmitters signal an acute stress response (also called fight-or-flight response, the two options one has, when facing danger) to the body which, in turn, puts a halt to the hunger signal. As a result, it causes a loss in appetite because the brain does not receive the hunger message.
How to Use Phentermine:
FDA recommends that Phentermine should be used for short term (up to 12 weeks) while following nonpharmacological plans to weight loss such as healthy dieting and exercise. The given reason is that phentermine loses its appetite-suppressing effects after the body adjusts to the drug. But it has been "shown" that phentermine did not lose effectiveness in a 36-week trial. Anyway, due to the risk of insomnia, it is generally recommended that the drug be taken either before breakfast or 1-2 hours after breakfast.
Phentermine Side Effects:
Generally, Phentermine based diet pills appear to be relatively well tolerated. Most side effects of Phentermine are:
- dry mouth
- unpleasant taste

- tremor
- insomnia

- difficulty doing exercise that you have been able to do
- euphoria and a psychological addiction to it if taken on a long-term basis.
Contact your doctor if any of the above symptoms are severe or do not go away.
- Phentermine may decrease the ability of the patient to engage in potentially hazardous activities such as operating machinery. So be cautioned accordingly.
- Combination therapy with phentermine and any other drug products for weight loss, including selective serotonin reuptake inhibitors (e.g. fluoxetine, sertraline, fluvoxamine, paroxetine), have not been established. Therefore, coadministration of these drug products for weight loss is not recommended.
