Artane (trihexyphenidyl) is an antispasmodic drug used to treat the stiffness, tremors, spasms, and poor muscle control of Parkinson's disease. Artane is also used to treat and prevent the same muscular conditions when they are caused by certain drugs. Side effects of Artane include:

  • dry mouth,
  • nervousness,
  • drowsiness,
  • dizziness,
  • large pupils,
  • blurred vision,
  • difficulty urinating,
  • constipation,
  • nervousness,
  • anxiety,
  • decreased sweating,
  • flushing, or
  • upset stomach.

As initial therapy for parkinsonism, a dose of 1 mg of Artane in tablet or elixir form may be administered the first day. Artane may interact with alcohol, tricyclic antidepressants, phenothiazines, thiothixene, chlorprothixene, antihistamines (often found in prescription and over-the-counter cold, allergy, and sleep medicines), quinidine, amantadine, digoxin, or haloperidol. Tell your doctor all medications and supplements you use. It is not known whether trihexyphenidyl will be harmful to an unborn baby. It is also not known whether this drug is excreted in human milk.

SIDE EFFECTS

Minor side effects, such as dryness of the mouth, blurred vision, dizziness, mild nausea or nervousness, will be experienced by 30 to 50 percent of all patients. These sensations, however, are much less troublesome with ARTANE (trihexyphenidyl) than with belladonna alkaloids and are usually less disturbing than unallenated parkinsonism. Such reactions tend to become less pronounced, and even to disappear, as treatment continues. Even before these reactions have remitted spontaneously, they may often be controlled by careful adjustment of dosage form, amount of drug, or interval between doses.

Isolated instances of suppurative parotitis secondary to excessive dryness of the mouth, skin rashes, dilatation of the colon, paralytic ileus, and certain psychiatric manifestations such as delusions, hallucinations, and paranoia, all of which may occur with any of the atropine-like drugs, have been reported rarely with ARTANE® (trihexyphenidyl)

Potential side effects associated with the use of any atropine-like drugs, including Artane (trihexyphenidyl) , include cognitive dysfunctions, including confusion and memory impairment; constipation, drowsiness, urinary hesitancy or retention, tachycardia, dilation of the pupil, increased intraocular pressure, choreiform movements, weakness, vomiting, and headache. Exacerbation of parkinsonism with abrupt treatment withdrawal has been reported. Neuroleptic malignant syndrome with abrupt treatment withdrawal has been reported (see WARNINGS, Neuroleptic Malignant Syndrome).

The occurrence of angle-closure glaucoma in patients receiving trihexyphenidyl HCl has been reported (blindness has been reported in some cases). Paradoxical sinus bradycardia, dry skin, and cycloplegia have been reported.

In addition to adverse events seen in adults, the following adverse events have been reported in the literature in pediatric patients: hyperkinesia, psychosis, forgetfulness, weight loss, restlessness, chorea, and sleep alterations.

Drug Abuse And Dependence

Although ARTANE (trihexyphenidyl) is not classified as a controlled substance, the possibility of abuse should be borne in mind due to its stimulant and euphoriant properties.
