Interaction Details
There were no interactions found between Levonorgestrel and Anhydrous Crystalline Maltose. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Anhydrous Crystalline Maltose Overview
Anhydrous crystalline maltose, a disaccharide composed of two D-glucose molecules connected by an alpha (1→4) bond, is produced from starch and used as a food stabilizer and desiccant in various industries. It is also simply known as 'malt sugar'. Orally, it is used for Sjogren syndrome and dry mouth associated with cancer chemotherapy or other medications. Research suggests that dissolving lozenges containing anhydrous crystalline maltose in the mouth can improve measures of unstimulated saliva volume in some patients with Sjogren syndrome. A variety of studies have reported that doses of up to 600 mg/day can be used safely for up to 24 weeks. Maltose, consisting of two glucose molecules, is less sweet than table sugar (sucrose), which is a combination of glucose and fructose.
Levonorgestrel Overview
-
Levonorgestrel is used to prevent pregnancy after unprotected sexual intercourse (sex without any method of birth control or with a birth control method that failed or was not used properly [e.g., a condom that slipped or broke or birth control pills that were not taken as scheduled]). Levonorgestrel should not be used to prevent pregnancy on a regular basis. This medication is to be used as an emergency contraceptive or backup in case regular birth control fails or is used incorrectly. Levonorgestrel is in a class of medications called progestins. It works by preventing the release of an egg from the ovary or preventing fertilization of the egg by sperm (male reproductive cells). It also may work by changing the lining of the uterus (womb) to prevent development of a pregnancy. Levonorgestrel may prevent pregnancy, but it will not prevent the spread of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome [AIDS]) and other sexually transmitted diseases.
