Why Was I Told?

About 150 years ago, it was thought that the only way for a patient to avoid complications during surgery was to completely starve and dehydrate the body. As with many topics, knowledge and research on this has progressed over the last 150 years. But, some doctors still use this method because it is easier for them to implement.

It was true 150 years ago and it's true today that your stomach should be free of solid foods, milky beverages, protein, fat and colored dyes found in sports drinks. These can put you at risk for serious complications during surgery.

Drinking clear liquids is safe up to 2 hours before surgery. ClearFast PreOp® clears from the stomach within 90 minutes, ensuring you have an empty stomach at the time of your procedure.

Not only is ClearFast PreOp® safe to drink before surgery, it's actually safer to drink a clear liquid before surgery than to have a stomach full of acid at the time of your procedure.

If you are preparing for and/or recovering from surgery, ClearFast PreOp can help you by providing the clear liquid nutrition and hydration that is key to a better recovery. It is ideal for healthy people undergoing both scheduled and/or elective surgery, or invasive diagnostic procedures performed in both hospitals and outpatient facilities.

ClearFast PreOp is specially formulated for patients who are undergoing general anesthesia or IV sedation, for all surgical procedures from orthopedic to cardiac… from gynecologic to neurologic. It is also appropriate for patients having colonoscopies, oral, and cosmetic surgeries plus cardiac catheterizations, etc.

Yes. Because each surgery and patient is different, you should always consult with your doctor to fully understand your preoperative needs and options.
ClearFast PreOp is ideally formulated for surgical patients who want to improve recovery after surgery. It uses 6 essential nutrients (complex carbohydrates, electrolytes, Vitamin A, Selenium, Zinc, L-citrulline) to nourish and hydrate the body.
You should consume one bottle of ClearFast PreOp the night before surgery and another bottle up to 2 hours prior to surgery. You can also consume another bottle after your procedure unless directed by your physician to not consume any food or drink after surgery.

ClearFast PreOp is ideal for consumption after surgery for patients who cannot or do not want to consume solid foods. If your doctor has directed you to not consume solid foods after surgery, please consult with him/her about how best to use ClearFast PreOp as a meal replacement or supplement.

ClearFast PreOp is specifically formulated for surgical patients and is the only clear liquid containing a significant volume of the complex carbohydrates, Vitamin A, minerals and L-citrulline that will improve recovery after surgery. Sports drinks typically contain simple carbs, sugars and coloring dyes. None of this is good.
Yes, ClearFast PreOp is safe to be consumed in the non-surgical setting. It contains the complex carbohydrates, electrolytes, amino acids, vitamins, and minerals that are key to proper nourishment.
Yes, ClearFast PreOp can be consumed by children under the supervision of their doctors and parent/guardians. It can be consumed both before and after surgery.

For children weighing under 50 kilograms or 110 pounds, we recommend dividing the full 12 ounce bottle into 3 servings (4 ounces each.) Children should consume the first two servings at 4 and at 3 hours before surgery and the last serving 2 hours prior to surgery in order to ensure proper absorption before the start of anesthesia.

A 40-50 kg adult could have the same ingestion schedule as a similarly sized child, that is, three servings of 4 ounces each at 4, 3 and 2 hours prior to surgery.

Yes, women in labor can drink ClearFast PreOp under the supervision of their doctor. If you are pregnant and scheduled for a cesarean section, you may be allowed to consume ClearFast PreOp up to 2-3 hours prior to your scheduled delivery.
ClearFast PreOp does not need to be refrigerated prior to being opened but should be after the safety seal is broken. ClearFast PreOp should be consumed by the expiration date printed on the bottle. Note that ClearFast is all-natural; if oxygen gets into the seal, it can create mold.
Yes, ClearFast PreOp is gluten free and naturally sweetened with Stevia Rebaudiana. It is also kosher.
