What is Lactaid?
Lactaid is a dietary supplement used by people with lactose intolerance to help them digest dairy products. Symptoms of lactose intolerance include bloating, gas, stomach pain, diarrhea, and cramping. Not only can Lactaid provide lactose intolerance relief, but it can also help people take in calcium and vitamin D by allowing them to consume milk products again. These products are recommended for those over four years of age. Lactaid also manufactures Lactaid milk (lactose-free milk) in many different flavors.

Important information about Lactaid
Lactaid contains the lactase enzyme, which breaks down lactose in dairy foods into smaller molecules that people with lactose intolerance can digest.
Follow all directions provided by your doctor and read all documents carefully, including the full Prescribing Information, FDA-approved Product Labeling, Instructions for Use, and Medication Guide, before using Lactaid. However, the following is a synopsis of the general guidelines for the use of Lactaid:
Lactase enzyme supplements, available in fast-act caplets and chewable tablets, should be taken with the first bite of food containing lactose, which includes ice cream, whole milk (cow’s milk), and cheese.
Lactaid also makes lactase drops, which can be added to milk to break down the lactose.
If your meal lasts more than 30 minutes, take another dose of lactase.
There are no known common side effects of Lactaid. If you use this product as directed on the label and continue to experience bloating, stomach pain, and diarrhea, consult your healthcare provider, as this may indicate another underlying issue.
Some individuals may experience serious side effects while using Lactaid. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:
- Serious allergic reaction, including swelling of the face or trouble breathing (anaphylaxis).
These are not all of the possible side effects of Lactaid. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.
Before starting Lactaid, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including whether you have:
Consistent bowel problems such as those listed above that are not consistently brought on by dairy products.
Previous hypersensitivity or allergic reaction to lactase or other components in Lactaid: mannitol, cellulose, sodium citrate, and magnesium stearate.
