Lasix is a brand name for the drug furosemide, a very potent diuretic.
Technically it belongs to a class of drugs known as loop diuretics, which will
cause the body to excrete water as well as potassium, sodium and chloride. Loop
diuretics are among the strongest such drugs available, having an extremely
dramatic effect on fluid levels in the body. Potassium levels need to be
particularly watched, Lasix greatly increasing the amount excreted. The use of
a prescription potassium supplement therefore is often required to keep levels
in balance, otherwise a serious heart complications might develop. Mistakes in
potassium dosage have equally serious consequences, so Lasix is clearly a risky
item to use. But when an athlete needs to shed water, it is very difficult to
find something that works better.
Athletes use diuretics for a couple of specific purposes. Competitive athletes
use these drugs to drop water weight, in an effort to make adjustments in their
weight class standings. Since the weigh-in is most often a day or days before a
competition/match, one can drop their bodyweight considerably and be back to
normal within hours after rehydration. This logically seems to provide an
unfair advantage, the athlete competing at a much heavier weight than believed.
This advantage is only offset by the now near universal nature of this
practice. Bodybuilders also rely heavily on diuretics when preparing for a
contest. It can efficiently lower subcutaneous water concentrations, helping to
produce that super-ripped look so common on stage today. Make no mistake; a
winning look is extremely difficult to obtain without some form of diuretic.
This drug is prepared as both an oral tablet (usually 20-40mg per tablet) or
IM/IV injection solution, the injection being much more rapid in effect. The
dosage and method of administration is tailored to the individual, dependent on
the desired goals and condition of the athlete. Tablets are the most common
form of administration. Each oral Lasix tablet becomes effective about 1 hour
after ingesting and will remain active for an additional 3 or 4 hours. The
athlete will usually start with a mild dose, and add to this amount accordingly
later in the day. The initial dosage is usually 20 to 40mg, with the maximum
amount usually not to exceed 80mg. The user will attempt to calculate the
optimal dosage, and determine the best intake schedule in relation to the show
or competition. In order to minimize the side effects associated with this
drug, it is generally used for no longer than a few days.
Since Lasix has such a strong effect on electrolyte and potassium levels, it is
much safer to addition a potassium sparing agent like Aldactone®
(spironolactone) than it is to keep increasing the amount of Lasix used. A
combination of 50mg Aldactone® and 20mg Lasix would be a good starting point,
having roughly the effect of a 40mg Lasix tablet without the notable potassium
loss. This dosage is repeated 2-3 times during the day and the effect judged to
determine the optimal dosage. It is important to remember that these drugs can
be active for many hours. It can become difficult to control the dehydrating
effect with an overlapping schedule, so one should be careful not to administer
such diuretics too frequently.
room to experiment, adjustments in dosage are much easier to make (the user not
having to wait very long to see an effect). And the optimal dosage is certainly
less trouble to calculate for a later time as well, the user having fewer
variables to worry about. But again, when used in a rush this drug can be
Lasix is no doubt one of the most dangerous drugs a competitor will use. This
can be seen on occasion when severe dehydration and electrolyte imbalance takes
the life of an ambitious athlete. Warning signs that Lasix may be causing
severe dehydration include (not limited to) dizziness, cramping, vomiting,
diarrhea, fainting and circulatory disturbances. Potassium depletion can be
marked as well, so as discussed users often opt to take a prescription
potassium supplement, also with its own set of dangers. One should use extreme
caution when considering using Lasix or other diuretics; they are certainly not
needed for recreational users.
This product is widely available. It is manufactured and sold under many
different brand names, in many countries. No version of Lasix (or any other
diuretic) is currently being counterfeited. When found on the black market it
can therefore be trusted. Although it is doubtful these will circulate, make
sure never to purchase the 500mg tablets. These are used only in severe medical
conditions, and contain a dosage that could prove fatal to a healthy person.
