A 40-year-old female asked:

how many hours do i need to space between 200mg doses of tessalon perles (benzonatate)?

4 hours: Tessalon usually starts working within 20 minutes of taking it with a duration of action of 3 - 8 hours. I would not take it more frequently than every 4 hours. Overdose is not generally a problem but the typical maximum dose is 600 - 800 mg per day.

In how many days will my milk supply come in?

3 doctor answers4 doctors weighed in
Dr. Michael Pappas
Pediatrics 23 years experience
1-10 days: Your pre milk or colostrum is probably already in, but your full milk supply can take a few days or more especially for the first time mom. A baby's cry, suckling, and holding your baby are all stimulants to your milk "letdown". Other factors which may help with your milk release is good hydration, good eating habits, drugs and sleep. Supplementation with formula can help in the meantime.

From none to many: Teeth eruption is quite a variable process. I have seen as many as 2 at birth and a few normal kids with none until 15 months. Some referances say to expect 1 by four months & 1 per month thereafter (or 9-10 at a year). The primary 20 are usuall all in by three.

Why is it necessary to get so many ultrasounds in pregnancy/

2 doctor answers7 doctors weighed in
Dr. Craig Keathley
Obstetrics and Gynecology 24 years experience
It isn't: In an uncomplicated pregnancy, repeated ultrasounds aren't necessary. A 1st trimester sonogram is best for confirming the due date and number of fetuses while fetal anatomy is best assessed in the mid to late 2nd trimester. Additional sonograms may be recommended if complications such as hypertension, diabetes, or pre-eclampsia arise, but for the uncomplicated, low risk patient, 2 should suffice.
