Lasix is a
brand name for the drug furosemide, a very potent diuretic. Technically
Lasix 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.
Lasix is
prepared as both an oral tablet (usually 20-40 mg 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 40 mg, with the maximum amount usually not to exceed 80 mg.
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 50 mg Aldactone
and 20 mg Lasix would be a good starting point, having roughly the effect
of a 40 mg 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.
The injectable is a much
more powerful version of the drug. It can be administered both
intramuscularly and intravenously, depending on the intensity the user is
looking for. The IV method is extremely fast, the strong effect of the
drug felt in a matter of minutes. Since the injection is much more
powerful than the oral, the dosage is to be considerably reduced in
comparison. The injected dosage is usually in the range of 10-40 mg,
rarely going any higher. Drug testing for Lasix at bodybuilding
competitions has increased the popularity of last minute IV diuretic use,
a very dangerous practice. Instead of slowly shedding water the few days
prior, the user is forced to wait until after the "piss-test". Then in a
frantic rush to remove subcutaneous water before the show, the drug is
administered. The user often has little time to adjust the dosage,
resulting in a number of fatal mistakes in recent years. The effect of
Lasix is actually easier to control with the injectable under normal
conditions. When there is 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 extremely dangerous.
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.
