Levsin

The active ingredient in Levsin is hyoscyamine sulfate. Levsin belongs to a class of medications known as anticholinergics/antispasmodics. It works to decrease acid production in the stomach and relax the muscles in your digestive tract and bladder. It also lessens the amount of certain body fluid secretions (saliva, sweat).

Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using Levsin. However, the following is a synopsis of the general guidelines for the use of Levsin:

• Take this medication orally exactly as directed by your physician.
• Levsin may increase the risk for heatstroke because it decreases sweating. Avoid becoming overheated in hot weather, saunas, and during any strenuous activity.
• If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose. Take your next dose at the regular time.
