Recommended Dosage

FDgard® Dosage Instructions

FDgard® should be taken as directed by the physician. (Usual adult dosage: two capsules, two times a day. Take 30-60 minutes before meal(s) with water. Do not exceed six capsules per day. Swallow capsules whole or mix contents with applesauce. Do not chew). FDgard® sachets (institutional packs) should be administered by a healthcare provider through a nasogastric or gastrostomy tube.

FDgard® has been formulated to be taken 30-60 minutes before a meal. If this pre-meal dosage is missed, the patients have dosing flexibility to take FDgard® during or after a meal.

Side Effects/Interactions

In very rare cases, allergic reactions to caraway oil and l-Menthol can occur. Use with caution in patients who have a history of gallstones. Like many other food extracts, there is no chronic use dosing data available on caraway oil and l-Menthol.

Although the SST® technology is designed to eliminate the heartburn and anal burning side effects seen in older delivery technologies,* it would still be advisable to counsel patients to avoid simultaneous intake of acid reducers such as antacids. Note: FDgard® may interact with certain medications (e.g., cyclosporine), affecting how the body can break them down.

“One will do anything to feel better, so my husband and I went to CVS/pharmacy and luckily found one remaining box on the shelf, I bought it, took it that afternoon and again the next morning. To my surprise and amazement, I felt great within a short time, and continued feeling wonderful.”
