Phentermine vs Sibutramine Differences

Phentermine and Sibutramine are medications that are effective for treatment of obese people. These medications were designed for people with BMI over 30 or people with BMI over 27 but with high amount of fat in the blood, type 2 diabetes and hypertension.

Phentermine has been used for obesity treatment since the second half of the last century and proved its efficiency during that time. Phentermine diet pills are recommended to use along with diets and physical exercises. Only this way people can lose weight significantly.

It is recommended to cure obesity by means of Phentermine under the supervision of an experienced doctor. People should note that Phentermine is a prescription drug, which causes some side effects. Maximal dose must not exceed 37.5 mg per day. People can use Phentermine only within a short time, 12 weeks maximum.

Patients must never use Phentermine, if they have the following pathologies:

  • Brain disease, associated with the blood vessels;
  • Thyroid gland hyperactivity;
  • Severe depressive disorders;
  • High blood pressure;
  • High intraocular pressure;
  • Alcohol or drug dependence.

Sibutramine was approved by the FDA in 1997. In the USA, it is known under the trade name Meridia. That time, people could buy Sibutramine in capsules, dosed 5 mg, 10 mg or 15 mg. Nowadays, Sibutramine is banned for obesity treatment in many countries (e.g. the USA, Canada, EU and Australia).

Sibutramine diet pills allow to reduce the food consumption and not to feel painful hunger. To increase the weight loss rate, doctors recommend to take Sibutramine, at the same time increasing physical exertion and keeping a diet.

Sibutramine some contraindications:

  • Mental disorders, including bulimia and anorexia;
  • Drug or alcohol addiction;
  • Hypersensitivity to Sibutramine or its elements;
  • Chronic cardiovascular diseases.

In addition, Phentermine and Sibutramine diet pills cannot be used in pregnancy and during breastfeeding. Using these drugs increases the risk of mental and physical abnormalities during the development of a child.

In most countries of the world, Phentermine and Sibutramine are not prescribed to patients, aged under 18 or over 65 years. Using any of these diet pills, patients should keep out of MAO inhibitors and drugs that can affect serotonin level.

If during the use of Phentermine or Sibutramine a patient doesn’t have any significant weight loss, then the doctor can recommend to change the dosage or to refuse from these diet pills.

Because Sibutramine is not recommended for the treatment of obesity and people cannot buy them in majority of the countries, we may assume that it is better to use Phentermine diet pills.
