Phentermine-containing drugs have been used for treatment of overweight and obesity for over 50 years now. Phentermine can cause side effects, allergic and other unusual reactions, just like many other anorexigenic drugs.

Most side effects of Phentermine are associated with pharmaceutical properties of the active substance. Rare side effects as well as allergic reaction can be provoked by inactive components.

People, receiving anti-obesity treatment using Phentermine, may have side effects of different severity. Usually, side effects arise when the human body adapts to the drug and disappear over a short period of time.

Phentermine anti-obesity medication reduces the appetite by stimulating certain parts of the brain, responsible for satiety. Therefore, it is no wonder that the common side effects of Phentermine pills occur from the central nervous system (CNS). The most common CNS negative reactions are:

  • worry and anxiety feeling;
  • automatic movement of extremities;
  • difficulty falling asleep and sleep maintenance;
  • emotional instability;
  • bad mood and disgust to any activity;
  • violation of spatial perception (dizziness)

Sometimes you can have a strong feeling of well-being, emotional uplift, happiness, excitation and joy. Euphoria, release from social taboos occur rarely and may be a signal of Phentermine overdose.

Second group of Phentermine side effects is associated with the influence of the drug on the cardiovascular system. Obese people often have heart problems; therefore, the review of cardiovascular Phentermine side effects is especially relevant.

The most common cardiovascular Phentermine side effects are increased heart rate (tachycardia), violation of the heart rhythm (arrhythmia) and high blood pressure (hypertension). During the use of such anorexigenic drugs, rare cases of severe pulmonary hypertension were registered.

Gastrointestinal Phentermine side effects can appear in the first few days of using the drug. Such side effects as frequent defecation, constipation, dryness in the mouth and other gastrointestinal disorders are not dangerous for health and can be easily cured if needed.

Rare negative reaction of Phentermine can manifest itself as erectile dysfunction and poor libido. Having noticed any moderate or severe Phentermine side effects, patient should better stop using the drug and consult a doctor or pharmacist.

The severity and frequency of Phentermine side effects depend on the proper use of the drug. Do not exceed the maximum recommended dose of Phentermine 37.5mg. If you forgot to take the pill, please do not take 2 pills at a time.

The risk of side effects increases in combined use of Phentermine and alcohol or other medications (for instance, antidepressants or thyroid hormones). Phentermine must be used with caution by patients, who already use any symptomatic or psychotropic medications.

You cannot buy Phentermine tablets in EU countries anymore. Medical Regulatory Authorities of the EU established that the benefit of Phentermine tablets did not surpass the risk of side effects and have temporarily withdrawn the drug license.
