A 25-year-old female asked:

can plan b lose effectiveness if i finished an antibiotic 3 days ago? still on birth control pill

No: In general you do not need to take Plan B if you were already on birth control. Most antibiotics will not interact with either Plan B or birth control. If you are uncertain in the future you can always ask the pharmacist or just use a condoms during those days.
Dr. Heidi Fowler
Psychiatry 25 years experience
Plan B does not: interact with many antibiotics. Antibiotics which can affect Plan B: ampicillin, cotrimoxazole (in Bactrim), Rifampin, tetracycline, & clarithromycin.

A 23-year-old member asked:

Is it possible to get rid of watery eyes, runny nose, and coughing mucus in a day?

Watery eyes: Sounds like you have a viral illness. Take an over-the-counter decongestant and see if this helps. A saline nasal spray is also helpful. Drink plenty of fluids and get some rest. If you are still having problems after 7 days, call your primary doctor.
A 40-year-old member asked:

I had my kidney stone removed by scope and stent removed 6 days after. Is it normal to still feel pain?

Not Usually: Typically, after a stone is removed the the stent is removed, the pain goes away almost immediately. Sometimes, there is still some swelling in the ureter that could be giving continued pain or even possible a small stone fragment. I would check with your doctor with the pain persisting that long.

A 36-year-old member asked:

Is progestin for 10 days a month or the mirena (levonorgestrel) IUD better for heavy menstrual bleeding?

Mirena (levonorgestrel): While there aren't any good head to head studies comparing each method, my patients have much better results with Mirena (levonorgestrel) iud. The Progesterone in it is slowly released the whole month and is more targeted to the uterus than taking 10 days of progestin pills. Also, there is a new amazing medicine called Lysteda (tranexamic acid) that is not a hormone and is very effective. Ask your doc about it!

A 20-year-old member asked:

I got a rash from nose-chin after halloween. I had 3 antibiotics, nothing happened. Could it be an allergy to chocolate/gluten/milk/lecithin....?

Unlikely: It would be unusual to have a persistent rash for two months after eating halloween candy. Skin inflammation from continued exposure to a skin irritant or allergen like cosmetics would be more likely although i don't know what your rash looks like. An allergist or dermatologist can patch test you to common causes of rash (contact dermatitis).
A member asked:

My 2 yr daughter has hand, foot and mouth disease for last 4 days. The ulcers / blisters in mouth make it difficult for her to drink and eat.. What medication will be most suitable?

Dr. Josephine Ruiz-healy
Pediatrics 39 years experience
Numb the mouth: Anything that will decrease the pain in the mouth will help her drink. Ice cold foods act as a local anesthesia as they numb the area. Try popsicles, ice cream, jello, as well as pedialyte popsicles that will keep her hydrated. Also oragel will help. As it is a viral disease, there is no antibiotics that will help it. It will go away on its own.
