Tarina Fe 1/20 & Vitamin B1
Depletes Vitamin B1. This medication is commonly used for Contraception
Why Tarina Fe 1/20 affects Vitamin B1
Studies suggest a potential for mild thiamine (vitamin B1) deficiency with long-term use of Oral Contraceptives (OCs). One finding showed that red blood cell activity of an enzyme dependent on thiamine (transketolase) decreased during OC treatment. This decrease indicates that the cells might not have enough thiamine to function optimally, suggesting a mild thiamine deficiency induced by the contraceptives. Supplementation with thiamine (vitamin B1) should be considered for women using OCs.

Related Health Impacts
- Sudden Confusion & Balance Loss
In susceptible adults, acute thiamine (vitamin B1) deficiency can rapidly trigger an encephalopathy marked by confusion, gait ataxia, and ocular motor abnormalities such as nystagmus or ophthalmoplegia. This classic triad is often incomplete at presentation, and only a minority of patients show all three features together initially, which contributes to delayed diagnosis. Because body stores are quickly exhausted, maintaining adequate ongoing thiamine intake is critical, and can reverse many of the acute neurologic signs if started early, whereas even short delays increase the risk of persistent cognitive impairment and structural brain injury on imaging.
