Chemical Name: Alprazolam
Brand Name: Xanax (available in generic)
Manufacturer: Pharmacia and UpJohn
Description: Xanax is in the benzodiazapine class of central nervous system active compounds. The exact mechanism of action is unknown.
Indications and Usage: Xanax is indicated for the management of anxiety
disorder or the short-term relief of symptoms of anxiety. Anxiety or
tension associated with the stress of everyday life usually does not
require treatment with an antiolytic medication. Xanax is also indicated
for
the treatment of panic disorder, with or without agoraphobia.
Contraindications, Warnings, and Precautions: Certain adverse
clinical events, some life-threatening, are a direct consequence of physical
dependence to Xanax. Even after relatively short-term use at
recommended doses, there is some risk for dependence.* The risk
is higher when
taking doses over 4mg per day for longer than 8 to 12 weeks. The potential
for psychological dependence is more of a risk in individuals with a
history of alcohol or drug abuse. Addiction prone individuals should
be under careful surveillance when receiving Xanax. DO NOT STOP
TAKING XANAX ABRUPTLY. This can cause withdrawal reactions, including
seizures. Signs of withdrawal may include heightened sensory
perception, impaired concentration, dysosmia (distortion of normal
smell perception), clouded sensorium, parasthesias, muscle cramps, muscle
twitches, diarrhea, blurred vision, appetite decreases and weight loss.
Anxiety and insomnia have also been reported. Withdrawal reactions
may occur when dosage reduction occurs for any reason, including forgetting
to take a dose. Xanax must be reduced gradually under the
doctor's supervision. Xanax can potentially cause fetal harm in pregnant
women. If Xanax is taken with other psychotropic agents or
anticonvulsant drugs, careful consideration should be given to the
pharmacology of the agents to be employed, particularly with compounds
that
may potentiate the actions of benzodiazepines. Alcohol should be avoided
while taking Xanax. Xanax may interact with the following
medications: imipramine, desipramine, fluoxetine, propoxyphene, oral
contraceptives, diltiazem, isoniazid, macrolide antibiotics such as
erythromycin and clarithromycin, and cimetidine.
Adverse Reactions: Possible common side effects include drowsiness and
light-headedness. Less common side effects may include
headache, confusion, restlessness, psychosis, transient hypotension,
tachycardia, dry mouth, nausea and vomiting, constipation and visual
disturbances.
Dosing Range: Dosing should be individualized for maximum beneficial
effect. Dosing can range from 0.25mg per day to 4mg per day. Some
individuals may require more depending on a variety of factors.
* Comment by MKC: short-term usage is recommended because of extreme risk of dependence!
