How soon after finishing your last terbinafine pill is it safe to start drinking alcohol again?

How soon after finishing your last terbinafine pill is it safe to start drinking alcohol again?

Good question: Terbinafine can cause chemical hepatitis & has a 36 hour half life. That means it takes about five days to clear your liver of all terbinafine. Alcohol is a known hepatotoxic substance. Although no clear contraindications are in the package insert for terbinafine, it seems prudent to forgo alcohol or Acetaminophen for a week after last dose of terbinafine to be safe. ...Read more

How long does it take terbinafine taken orally (250 mg 1 time daily) to begin to improve fungal folliculitis? I haven taken 3 pills over 3 days but no improvement yet.

Weeks: Fungal infections are slow growing, and therefore slow to resolve. That's why you have to take medication for a while. Even after the fungus is killed, the rash itself takes a while to heal.

Be patient. ...Read more

Terbinafine halflife: Thank you for your question. When used for short-term use (2 weeks), Terbinafine's half-life is defined as 36 hours, therefore it exits the bloodstream after 72 hours. When used for 90 days for nail infection, Terbinafine may be present in the nail plate for much longer, but not the bloodstream. Varying underlying conditions may alter this and assessment by a medical professional is helpful. ...Read more

EVEN IF ALL THE GENERIC DRUGS DO HAVE THE PROPER AMOUNT OF THE DESIGNATED AND PRESCRIBED MEDICATION, THERE ARE A HOST OF DIFFERENCES IN EACH.
COLOR, SHAPE, SIZE, IMPRINT, EXCIPIENTS ARE ALL DIFFERENT!
I HAVE WRITTEN BOOKS ON DRUG REACTIONS.

When will I see an improvement when taking terbinafine (oral) for 3 months?

Several months: For skin, 10 days. Fingernails are fully replaced in 6 months. 12 months for toenails. For toenails about 60% of people see complete clearing in a year, with partial clearing seen much sooner and gradually pushing the abnormal nail off the edge. A nail is not a living tissue, cannot repair itself. So people take terbinafine for 3 months hoping to have a healthy toenail a year later. ...Read more
