Get re-tested first: A very important consideration before stopping PrEP is to be re-tested for HIV first, and enough time needs to pass after your last unprotected encounter to ensure a valid test result (as little as 2 weeks with modern in-office testing, longer with home test kits). Stopping PrEP before re-testing could result in loss of any protective effect it's having on a recent exposure.

A 39-year-old member asked:

What could cause the left side of my jaw to lock up after catching a cold a few days ago?

TMJ disorder: A locked jaw is usually due to a temporomandibular joint that is injured or displaced. This could happen when you are ill from clenching too much, or a wide yawn if you already have aproblem with the joint. Go see an ent. If severe a few days of a steroid will help, then you may need an occlusion splint made by a dentist.

How does a man's sex life change with aging?

Lowered function: While sexual potential can carry through into quite older age, the erectile capacity and ejacualate volume decrease with age. Some lose desire which is entirely psychological. Note the many products on the market for this and the destruction of endangered animals for this (rhino horns, bear gall bladder stones, etc.).

Remember...: Remember why you started in the first place and how much better you felt while doing it. Also, schedule it as an appointment. Even if you don't want to do it, do 10 minutes. You can always find 10 minutes. Right?

Not your periods: Both menses sound normal being moody is likely related to other circumstances (husband, kids, job, money ?).

A 36-year-old male asked:

Is it safe to take 5 metformin pills & 5 onglyza (saxagliptin) pills on 1 day and take a break for 5 days while fasting?

Dr. Richard Scofield

Absolutely not!: There is no rationale for taking metformin or Onglyza (saxagliptin) in that fashion and taking such large amounts all at once may lead to toxic side-effects.
Dr. William Harris
Family Medicine 33 years experience
The equivalent 5-day Onglyza treatment would be once-weekly Bydureon injections. You get all of the benefits of a daily pill in a weekly shot. There is no equivalent, weekly (more convenient) dosing form of metformin yet -- we're still stuck with the once-daily metformin so far...
