Levbid (hyoscyamine sulfate)
Last reviewed · Source: First Databank (FDB) drug data
Overview
Hyoscyamine is a naturally occurring tertiary amine antimuscarinic.
USES: Hyoscyamine is used to treat a variety of stomach/intestinal problems such as cramps and irritable bowel syndrome. It is also used to treat other conditions such as bladder and bowel control problems, cramping pain caused by kidney stones and gallstones, and Parkinson's disease. In addition, it is used to decrease side effects of certain medications (drugs used to treat myasthenia gravis) and insecticides.
This medication works by decreasing acid production in the stomach, slowing down the natural movements of the gut, and relaxing muscles in many organs (such as the stomach, intestines, bladder, kidney, gallbladder). Hyoscyamine also lessens the amount of certain body fluids (such as saliva, sweat). This medication belongs to a class of drugs known as anticholinergics/antispasmodics.

Dosing
No dosing information is available for this tab.
Hyoscyamine is administered orally. Hyoscyamine sulfate is usually administered orally or sublingually. Hyoscyamine sulfate also may be administered by IV, IM, or subcutaneous injection when oral or sublingual administration is not feasible or when rapid therapeutic effect is necessary. Hyoscyamine sulfate is commercially available as conventional (immediate-release) tablets, extended-release capsules and tablets, oral solutions (drops), elixirs, sublingual tablets, orally disintegrating tablets, and injection.
Immediate-release preparations of hyoscyamine sulfate (conventional, sublingual, or orally disintegrating tablets; oral solutions (drops); elixirs) generally are administered orally or sublingually 3-6 times daily.
Extended-release preparations of hyoscyamine sulfate should not be crushed or chewed. Symax(R) SR and Symax(R) DuoTab(R) tablets should be swallowed whole, while Levbid(R) tablets and certain generic preparations are scored and may be broken in order to titrate dosage. Extended-release preparations generally are administered every 12 hours, but preparations that are not scored may be administered every 8 hours if dosage adjustment is required. Patients should be advised that extended-release preparations may not completely disintegrate and fragments may be excreted in stools in some patients.
Sublingual tablets of hyoscyamine sulfate (i.e., Levsin(R)/SL, Symax(R) SL, generic preparations) may be administered sublingually or orally. Certain sublingual tablets (e.g., Levsin(R)/SL, certain generic preparations) also may be chewed. The manufacturers of Levsin(R)/SL and certain generic preparations state that oral administration of the sublingual tablets results in similar pharmacologic effects as sublingual administration, although the onset may not be as rapid.
Orally disintegrating tablets of hyoscyamine sulfate (i.e., NuLev(R), Symax(R) FasTab(R), generic preparations) are administered by placing a tablet on the tongue to dissolve and be swallowed with the saliva; orally disintegrating tablets may be administered with or without water. Individuals with phenylketonuria (i.e., homozygous genetic deficiency of phenylalanine hydroxylase) and other individuals who must restrict their intake of phenylalanine should be warned that each 0.125-mg NuLev(R), Symax(R) FasTab(R), or generic hyoscyamine sulfate (marketed by Ethex) orally disintegrating tablet contains aspartame (NutraSweet(R)), which is metabolized in the GI tract to provide about 1.7, 4.5, or 0.5 mg, respectively, of phenylalanine following oral administration.
Because antacids may decrease absorption of oral hyoscyamine sulfate when these drugs are administered simultaneously, most manufacturers recommend administration of hyoscyamine sulfate before meals and administration of antacids postprandially. One manufacturer recommends routine administration of hyoscyamine sulfate (Symax(R) formulations) 30-60 minutes before meals.
Hyoscyamine sulfate injection may be administered by IV, IM, or subcutaneous injection without prior dilution. Parenteral hyoscyamine sulfate solutions should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.
