Pharmacist Analysis
Mommy's Bliss Gripe Water is intended to help treat colicky infants and soothe gastrointestinal discomfort.
There is no 'standardized' gripe water formula, but generally, gripe water formulas contain a blend of herbal ingredients. Mommy's Bliss contains the following:
- Organic Fennel Seed
- Organic Ginger Root
- Purified Water
- Vegetable Glycerin
- Citrus Bioflavonoid Extract
- Citric Acid
- Sodium Bicarbonate
- Potassium Sorbate
- Natural Fennel Flavor
It is important to note that Mommy's Bliss Gripe Water contains sodium bicarbonate, which is commonly known as baking soda. It is a well-known acid neutralizer and likely plays a key role in relieving colic symptoms if excess acid is at least partially responsible for the symptoms being experienced.
While there is no interaction between Mommy's Bliss Gripe Water and the drug in question here, it is important to note that Mommy's Bliss Gripe Water does have some theoretical ones with other drugs simply based on the fact that two herbals in the product, ginger, and fennel, can affect the metabolism and/or effects of some substances.

Methotrexate Overview
-
Methotrexate is used to treat severe psoriasis (a skin disease in which red, scaly patches form on some areas of the body) that cannot be controlled by other treatments. Methotrexate is also used along with rest, physical therapy, and sometimes other medications to treat severe active rheumatoid arthritis (RA; a condition in which the body attacks its own joints, causing pain, swelling, and loss of function) that cannot be controlled by certain other medications. Methotrexate is also used to treat certain types of cancer including cancers that begin in the tissues that form around a fertilized egg in the uterus, breast cancer, lung cancer, certain cancers of the head and neck, certain types of lymphoma, and leukemia (cancer that begins in the white blood cells). Methotrexate is in a class of medications called antimetabolites. Methotrexate treats cancer by slowing the growth of cancer cells. Methotrexate treats psoriasis by slowing the growth of skin cells to stop scales from forming. Methotrexate may treat rheumatoid arthritis by decreasing the activity of the immune system.
