Today the most prescribed weight loss medications are the following:

  • Xenical (orlistat)
  • Adipex (Phentermine) (click here)
  • Qsymia (phentermine/topiramate)
  • Belviq
  • Contrave (bupropion/naltrexone)

These strong oral weight loss pills can only be prescribed to those obese patients whose BMI (body mass index) is more than 27-29. Such extreme obesity is typically accompanied by such health problems as hypertension, high cholesterol level and/or diabetes mellitus.

It is important that you provide an accurate medical history when visiting your doctor. Women should let their doctors know if they are planning a pregnancy, are already pregnant, or are breastfeeding newborns.

Any patient has to provide one’s doctor with any known health conditions, for example allergies or adverse reactions to medications as well as any medications that are currently being taken, including vitamin, mineral, or herbal supplements.

Xenical® (orlistat)

xenical diet pills 2015The weight loss medicine orlistat acts by assisting your body to block the absorption of fat contained in digested foods by about a third (30%). This weight loss medication inhibits the substance in pancreatic lipase that breaks down the fat in your diet to be absorbed by the body.

It is the only fat-blocker medication that was approved in the USA (in 1999).

Orlistat is prescribed in a form of oral 120mg tablets under the brand name Xenical.

It can also be purchased in a non-prescription diet pills form under brand name Alli, but this version only contains half of the prescribed dose of orlistat (60mg).

Your therapist may first require that you are eating low-fat meals before prescribing Xenical from which you acquire 30 percent or less of a standard daily calorie intake (1500 kcal) from fatty foods.

You may also be advised to take multivitamins a couple of hours either before or after ingesting the diet pill to help replenish vital A, D, E and K vitamins that are not readily absorbed when taking Xenical.

A very small number of patients using orlistat for the treatment of obesity have experienced severe injury to their livers, but studies are inconclusive that the weight loss medication actually causes these issues.

As long as you avoid foods with high calorie content, adverse reactions are relatively mild and include cramps in the abdomen, increased or uncontrollable bowel movements, diarrhea and flatulence.

Never-the-less, if you consume foods high in fat while taking orlistat, these symptoms may increase in intensity.

Qsymia® (phentermine/topiramate)

Approved in 2012 by USFDA for weight loss, the Qsymia diet pill is a combination of Phentermine (an appetite suppressant ) and Topiramate (medicine which is often used to treat brain seizures).

Qsymia acts by making a patient feel fuller than normal, raising metabolism to burn calories faster, and transforming the taste of foods so the patient has less desire to eat them.


This weight loss medicine can be used long term, although the FDA recommends that either doses are increased by your doctor or that the drug treatment is ceased after 3 months if at least 3% of patient’s total weight is not lost during that period of time.

Your doctor may require that you get heart checkups regularly after first beginning to use Qsymia or if the required dosage is increased.

Due to its health risks, Qsymia is not prescribed for pregnant females for the treatment of obesity. It is also advisable to have a pregnancy test completed prior to taking the drug and some form of birth control should be used while taking it.

Tests to determine pregnancy have to be administered monthly while taking Qsymia for weight loss.

Due to Qsymia raising heart rate and hypertension risks, it should not be used in patients with a history of cardiovascular disease, hyperthyreosis, or glaucoma.

It is common to experience slight adverse reactions including dry mouth, insomnia, tingling in the feet or hands, dizziness, constipation and altered tastes of foods or beverages.

Some people experience side effects that are more serious that require treatment from their doctor or other health care professional.

Such side effects include a significant increase in heart beat rate, vision problems, and thoughts or attempts of suicide.

Belviq® (lorcaserin)

Belviq is frequently prescribed for the long-term use. However, the FDA advises to quit the medicine after 3 months if approximately 5 percent of body mass has not been lost.

Pregnant females, or those who plan on trying to get pregnant, should not take this weight loss pill. Also, those who have been prescribed Belviq (lorcaserin) and are taking certain types of medications for depression should have frequent medical checkups. Some people in this category can contract bouts of confusion, fever and other dangerous symptoms associated with a rare reaction.

Those diagnosed with diabetes who take Belviq can experience coughing, headaches, fatigue, back pain and hypoglycemia (a drop in blood sugar).

Common symptoms experienced by healthy people taking Belviq include mouth dryness, fatigue, dizziness, headaches, nausea and constipation.

Contrave® (bupropion/naltrexone)

Contrave is a diet pill that uses a combined mixture of bupropion and naltrexone, both of which are endorsed in the USA. Bupropion is normally prescribed for patients who want to stop smoking. Alcohol and opioid abuse are often treated with Naltrexone. When combined, these two medications have been found to help reduce weight in those taking them.

Contrave can be taken for long-term periods, but the FDA recommends cessation of the medication after 3 months if the obese patient did not manage to lose at least 5-10% of the overall body weight.

Seizures and related disorders have been documented in some patients taking Contrave as well as significantly elevated heart rates and blood pressure. The ingredient bupropion has a few cases of elevating suicide risks and neuropsychiatric problems that can become serious.

Most people taking Contrave experience a variety of side effects which are considered common. These include dry mouth, headaches, nausea and vomiting, dizziness, diarrhea or constipation, and insomnia.
