Question 1

i am on keflex for acne, as well as mononessa for bc, my dermo told me keflex would not interfere with the bc pills- is this true?

Accepted Answer

Conflicting studies: 1st of all, no oral bc is 100% effective in preventing pregnancy. 2nd, antibiotics can interact with bc and possibly reduce bc effectiveness. 3rd, study results are conflicting -- some said antibiotics use while on bc increases risk of pregnancy, others said they don't. Advice: if worried, use a 2nd method of bc such as condom (which can lower risk of contracting stds).

Question 2

will keflex 250 help with acne? is this dose too low to make a difference?

Accepted Answer

Maybe.: Keflex might lessen your acne, but that's not what it is for. The best current antibiotics for acne are Doxycycline and minocycline, with a few others used less commonly - but antibiotics are not that effective all by themselves. Let your dermatologist design a comprehensive acne treatment for you, which will probably include an antibiotic and appropriate topical therapies.

Dermatologist ASAP: Some acne is resistant to antibiotics. Other treatments are available, but require specialist care. If you're not under care of a dermatologist, ask for referral to one right away. Prompt treatment may be needed to prevent permanent scarring. With modern treatment, nobody should ever have to deal with that lifelong problem. Good luck!

Question 5

Accepted Answer

Hormonal acne: If you are not on any oral contraceptives, need to be tested for hormone levels. Women may have hormone imbalance due to polycystic ovary syndrome which may also have irregular menses, hair loss or excess hair growth. There are meds to help. Cystic acne is one form if acne with larger red acne lesions. Usually also has blackheads & whiteheads as well. Antibiotics not great for hormonal acne.

Question 9

Safe is relative: It is a utilized therapy for acne, as are several other oral antibiotics.  But anytime you undertake long term antibiotic use, there is a chance of an adverse effect like antibiotic associated diarrhea, c.diff colitis, alterations in the natural bacteria of your body, resistant microbes.  With that said, it's still rather safe.

Question 10

i am a female, 40's, taking 250 mg of cephalexin for over 5 years 1x daily for cystic acne with probiotic. should i be concerned with long term use?

Accepted Answer

I would: Antibiotics tend to lose effectiveness with time due to bacteria developing resistance to it. You don't mention how effective it's been for you, so more information in that direction may be helpful as well. Probiotic supplement is a must with the use of antibiotic, whether short or long term, but you may ask your derm doc if there are other options available in this day and age.
