How to Buy Prescription Phentermine

Updated June 13, 2017

Phentermine is a prescription weight loss drug that is part of the sympathomimetic family of appetite suppressants. Phentermine is used for short-term management of obesity along with diet, exercise and behaviour therapy. Phentermine comes in tablets, capsules and resin capsules. Phentermine works by stimulating the hypothalamus gland and affects neurotransmitters to decrease the appetite. Deciding to buy prescription phentermine can be an important step in your struggle for weight loss when diet and exercise alone fail.

Review Phentermine's side-effect profile. Common side effects include depression, high blood pressure, irritability, nervousness and drowsiness. Watch out for other less common and rare side effects.

Discuss your health history and current medications with your doctor to ensure that taking Phentermine does not put you at risk. Inform your doctor of allergies, alcohol-abuse history, atherosclerosis, diabetes, history of drug abuse, mental illness, glaucoma, hyperthyroidism, kidney disease, hypertension, cardiovascular disease and if you have used an antidepressant drug within the past two weeks.

Decide how you would like to purchase the Phentermine. Any prescription drug coverage may dictate how and where you have to fill the prescription. If you choose to purchase Phentermine online, ensure that the pharmacy is trustworthy. Online pharmacies should verify the prescription. Verify shipping costs.

Purchase the prescription and if it is at a local pharmacy, ask the pharmacist any lingering questions about Phentermine and its side effects. Ask the pharmacist what time of day is best to take it and if it needs to be taken with food.


Phentermine is meant to be used in conjunction with diet, exercise and behaviour therapy to achieve maximum effect and acquire a healthy lifestyle.
