A prescription medication or drug requires a doctor’s prescription before you can
buy one at the pharmacy or drugstore. All prescription drugs are FDA-approved as
a safe and effective drug when taken as directed. They are often more potent or more
powerful than a similar non-prescriptive drug obtainable over the counter, whether
using similar ingredients or not.
With similar ingredients, prescriptive drugs are known to contain higher dosage.
They may also contain entirely new and uncommon ingredients which, while FDA approved,
may still require additional clinical tests to determine long term efficacy and safety.
Prescriptive diet pills are no different.
Types Of Prescription Diet Pills
Prescriptive diet pills generally fall under the same categories as OTC diet pills.
These can be appetite suppressants or fat absorption inhibitors, naturally or pharmaceutically
• Appetitive suppressants work by stimulating neurosensors in the stomach to increase
serotonin or catecholamine chemicals in the brain that signals that you are full
and not hungry. Phentermine-formulated weight loss drugs are FDA approved prescriptive
weight loss solutions that have not been associated with adverse side effects. Other
known drugs initially approved like Pondimin and Redux were taking off the market
in 1997 due to their potential damage to heart valves.
• Fat absorption inhibitors work using fibrous fat binding molecules that trap fatty
lipids ingested from being absorbed by the body and are passed out as stools in your
bowel movement. Xenical is the only approved appetite suppressant known to block
around 30% of ingested fat from being absorbed. It is now an OTC drug marketed as
Pro And Cons
Prescription medication is always FDA approved. That means you know it’s safe after
it has undergone all the clinical trials required to get it approved. On the other
hand, OTC drugs may or may not be safe. If they were once prescribed drugs and are
reclassified as OTC drugs, no problem. But most OTC drugs merely conform to the OTC
monograph to contain the FDA approved substances, dosage, labeling and warning to
make it commercially available. They are not backed by any clinical tests.
In general, prescription pills have the expertise of your doctor behind it. He/She
is the best person to prescribe one based on your health and medical condition, not
on a say-so of ads and product claims from OTC vendors. You can also be assured that
your progress is correctly monitored and any adverse effect can be caught before
they aggravate your condition.
On the other hand, prescriptive drugs have potent ingredients that can be addictive
especially if they are meant to be used for short-term medication like amphetamines.
The biggest concern lies in the fact that prescriptive weight loss pills have not
been studied for their long term effects, even if FDA-approved.
So you don’t know if their adverse effect will kick in later, even after getting
off them. Lastly, with a potent set of ingredients, there is often no escaping their
side effects. Depending on your condition, the effect can wear off after acclimatizing
to their use, or they can be serious enough to warrant getting another prescriptive
