What is the best way to stop finasteride ? all of a sudden or gradually ? , can sudden withdrawal cause rebound effect and more worsening (speaking of side effects not hairloss) ? and if gradual withdrawal is the best then how can i do so ?
The half-life of the drug in your body is somewhere between 4-6 hours. That means essentially that most of the drug that you take today will be gone tomorrow. Once the drug levels drop below a certain level, you will lose the effectiveness of the drug and it may take 1-3 months for the impact of the loss to be seen in your hair falling out. Tissue levels may maintain the effect of the drug for a couple of weeks or so.
The answer to your question — there’s no “best” way to stop the medication.
