Lithium is teratogenic and can cause birth defects at high doses, especially during the first trimester of pregnancy. The use of lithium while breastfeeding is controversial; however, many international health authorities advise against it, and the long-term outcomes of perinatal lithium exposure have not been studied.

Women should speak to their doctor or healthcare professional before starting or stopping any medications while pregnant. [1] Drugs taken in pregnancy including over-the counter-medications, prescription medications, nutritional supplements, recreational drugs, and illicit drugs may cause harm to the mother or the unborn child.
Radioactive isotope table "lists ALL radioactive nuclei with a half-life greater than 1000 years", incorporated in the list above. The NUBASE2020 evaluation of nuclear physics properties F.G. Kondev et al. 2021 Chinese Phys. C 45 030001. The PDF of this article lists the half-lives of all known radioactives nuclides.
The plasma half-life is one hour and is not altered appreciably by the thyroid status of the patient. Due to the concentration in the thyroid, however, dosing intervals may last 8 hours or longer. Less than 10% of the drug is excreted unchanged, with the remaining fraction undergoing extensive hepatic metabolism via glucuronidation .
Seven radioisotopes have been characterized, the most stable being 8 Li with a half-life of 838 ms and 9 Li with a half-life of 178 ms. All of the remaining radioactive isotopes have half-lives that are shorter than 8.6 ms. The shortest-lived isotope of lithium is 4 Li, which decays through proton emission and has a half-life of 7.6 × 10 −23 ...
The soft drink 7Up was originally named "Bib-Label Lithiated Lemon-Lime Soda" when it was formulated in 1929 because it contained lithium citrate. The beverage was a patent medicine marketed as a cure for hangover. Lithium citrate was removed from 7Up in 1948 [5] after the Food and Drug Administration banned its use in soda. [6]
Lithium has been associated with side effects to the fetus when taken during pregnancy, including body and heart abnormalities (e.g., Ebstein's anomaly); these effects have been documented in all trimesters, but higher risks, particularly for structural heart problems and spontaneous abortion, are typically seen with exposure in the first ...
The half-life of desvenlafaxine is about 11 hours, and steady-state concentrations are achieved after 4 to 5 days. [58] The half-life of duloxetine is about 12 hours (range: 8–17 hours), and steady-state is achieved after about 3 days. [11] Milnacipran has a half-life of about 6 to 8 hours, and steady-state levels are reached within 36 to 48 ...
