Negative Side Effects from Phentermine

As any prescription medicine Phentermine can lead to mild, moderate and rarely severe side effects, which are quite different from the positive anticipations from a weight loss medication. If any side effects during the use of Phentermine occur the least thing you should do is panic. When using you are likely to feel your heart and blood pressure to be affected.

If you have experienced one of the following symptoms you should talk to your doctor as soon as possible:

  • Swelling of the feet and legs
  • Swollen lips, tongue or face
  • Chest pain
  • Hallucination
  • Severe headache
  • Breathing problems
  • Closing of the throats
  • Vision problems
  • Random heartbeats
  • Abnormal behavior
  • Fainting

Besides the above mentioned health condition that pose a risk to your health, there are also mild side-effect that may occur during Phentermine use that don’t require immediate medical assistance.

However, it is recommended that you inform your doctor about the following symptoms, especially if they occur more than once or seriously disturb you:

  • Sudden increase in the blood pressure
  • Lethargy
  • False sense of being
  • Hopelessness
  • Nervousness
  • Touchiness
  • Fatigue

Other Phentermine side effects that have been reported to occur rarely:

  • Diarrhea
  • Dim or blurred vision
  • Vomiting
  • Headache
  • Irregular heartbeats
  • Lightheadedness
  • Foul taste
  • Mouth dryness
  • Confusion
  • Ineptnes
  • Alteration of sexual drive

Phentermine has the potential to form a habit over a long period of time that may result in Phentermine dependency in the long run. And as with any other forms of physical and psychological dependency you may experience withdrawal symptoms in case you stop taking the drug immediately. When finishing a course of the dosage should be gradually decreased.

If you suddenly stop taking Phentermine the following withdrawal symptoms are likely to occur:

  • Nausea
  • Personality disorder
  • Fatigue
  • Skin problems
  • Stomach pains
  • Rickety
  • Ghastly nightmares
  • Touchiness
  • Hyperactivity
  • Mental disturbances

The common impulses during Phentermine withdrawal are to continue taking the drug and increase its dosage. These are psychological withdrawal symptoms. Speak to your healthcare assistant if you experience any of the above mentioned effects.

Generic Phentermine such as Adipex, Acomplia, Xenical or Meridia possess the same negative side effect potential because they share the same active ingredients and mechanism of action with phentermine.
