Indications & Uses

Q-late is indicated for:

Pharmacology

6s-5-methyltetrahydrofolate is a water-soluble vitamin B. In the body it works as a coenzyme or co-substrate in making DNA and RNA and in the metabolism of amino acids. Deficiency is common during pregnancy, and it may lead to fetal malformations such as neural tube defects. Inadequate maternal folate status has also been linked with low infant birth weight, preterm delivery and fetal growth retardation. Spina bifida and anencephaly are the most common neural tube defects (NTDs). Folic acid supplementation before conception and during the first trimester has been shown to reduce the recurrence of NTDs in women. Supplementation is used to treat megaloblastic anemia during pregnancy. 68-5-methyltetrahydrofolate is a fourth generation folate derivative, a new generation of folic acid derivative made up of 6S-5-methyltetrahydrofolate and glucosamine salt. It is readily active and has the added advantage of higher bioavailability, safety and stability.

Cautions & Contraindications

Warnings & Precautions

Folic acid on its own is not enough to treat pernicious anemia, or other megaloblastic anemias where Vitamin B12 is deficient. In doses above 0.1 mg daily, folic acid may hide pernicious anemia, because the blood picture can go into remission (hematologic remission) while the neurological problems keep getting worse. When this nutritional supplement is prescribed for pregnant women, nursing mothers or women before conception, their medical condition should be considered, along with any drugs, herbs and/or supplements they are taking.

Contraindications

Patients who are known to be hypersensitive to 6s-5-methyltetrahydrofolate, or to any of the other ingredients in the product, should not take it.

Pregnancy & Breastfeeding

Folic acid is considered safe and acceptable to use in pregnancy. It is actively secreted into breast milk. A breastfeeding mother may need supplements if poor eating habits have left her deficient and led to megaloblastic anemia. The American Academy of Pediatrics considers folic acid compatible with breast feeding.
