Mefloquine Hydrochloride Tablets are indicated for the treatment of mild to moderate acute malaria caused by mefloquine-susceptible strains of P. falciparum (both chloroquine-susceptible and resistant strains) or by Plasmodium vivax. There are insufficient clinical data to document the effect of mefloquine in malaria caused by P. ovale or P. malariae. Note: Patients with acute P. vivax malaria, treated with mefloquine, are at high risk of relapse because mefloquine does not eliminate exoerythrocytic (hepatic phase) parasites. To avoid relapse, after initial treatment of the acute infection with mefloquine, patients should subsequently be treated with an 8-aminoquinoline derivative (e.g., primaquine). Mefloquine Hydrochloride Tablets are indicated for the prophylaxis of P. falciparum and P. vivax malaria infections, including prophylaxis of chloroquine-resistant strains of P. falciparum. Use of mefloquine hydrochloride tablets is contraindicated in patients with a known hypersensitivity to mefloquine or

MEDICATION GUIDE
Mefloquine Hydrochloride Tablets USP
Important:
Your doctor or pharmacist will give you an Information Wallet Card
along with this
Medication Guide. It has important information about mefloquine and
should be carried with
you at all times while you take mefloquine.
What is the most important information I should know about mefloquine?
Mefloquine can cause serious side effects, including:
1. Heart Problems.
Do not take halofantrine (used to treat malaria) or ketoconazole (used
for fungal infections) with
mefloquine or within 15 weeks of your last dose of mefloquine. You may
get serious heart
problems (problems with the electrical system of your heart called QT
prolongation) that can lead
to death. Do not take quinine (Qualaquin) or quinidine (used to treat
malaria or irregular heart
beat) with mefloquine. You may get serious heart problems.
2. Mental problems. Symptoms of serious mental problems may include:
•
severe anxiety
•
paranoia (feelings of mistrust towards others)
•
hallucinations (seeing or hearing things that are not there)
•
depression
•
feeling restless
•
unusual behavior
•
feeling confused
Some people who take mefloquine think about suicide (putting an end to
their life). Some people who were
taking mefloquine committed suicide. It is not known if mefloquine was
responsible for those suicides.
If you have any of these serious mental problems, or you develop other
serious side effects or mental
problems, you should contact your doctor right away as it may be
necessary to stop taking mefloquine and
use a different medicine to prevent malaria.
3. Problems with your body’s nervous system. Symptoms of serious
nervous system
problems may include:
•
dizziness

a feeling that you or things around you are moving or spinning
(vertigo)

CLINICAL PHARMACOLOGY
PHARMACOKINETICS
_Absorption: _The absolute oral bioavailability of mefloquine has not
been determined since
an intravenous formulation is not available. The bioavailability of
the tablet formation
compared with an oral solution was over 85%. The presence of food
significantly
enhances the rate and extent of absorption, leading to about a 40%
increase in
bioavailability. In healthy volunteers, plasma concentrations peak 6
to 24 hours (median,
about 17 hours) after a single dose of mefloquine. In a similar group
of volunteers,
maximum plasma concentrations in mcg/L are roughly equivalent to the
dose in
milligrams (for example, a single 1000 mg dose produces a maximum
concentration
