Does 100 mg of topomax a day interfere with the birth control ortho novum 7/7/7?

Does 100 mg of topomax a day interfere with the birth control ortho novum 7/7/7?

Is micronor (norethindrone) effective full 24 hrs when taken on time? Or is 1 hr before taking pill not good time for sex?

Is micronor (norethindrone) effective full 24 hrs when taken on time? Or is 1 hr before taking pill not good time for sex?

OCP efficacy : As with all oral contraceptives (especially Progesterone only pills) it is important to take the pills at consistent time each day. If you have been taking them consistently since your last period it does not matter what time of day you take it or when you have sex, for that matter. More important is the consistent daily use. ...Read more

On trt. Three pills sublingually daily. Each pill is 50mg of t compounded with 0.5mg of armidex.  Is this a scary dosage?

Safe testo dose: It appears you're taking 150mg and 1.5 mg. Of testosterone+arimidex sublingually on a daily basis. That is a very high dose of both substances.

May be: Why use vivelle (estradiol) for pmdd?

The other possibility is, of course menopause. Check your fsh after several days off the patch. ...Read more

In most cases, hormonal effects probably begin promptly within a few days after the injection. Lupron (leuprolide) is not a recommended contraceptive; it is also expensive, has other indications and has some potential long term side effects. ...Read more

If spironolactone (for acne) is androgen blocker - how does this not have any interaction with androgenic progestin such as levonorgestrel/Mirena?

If spironolactone (for acne) is androgen blocker - how does this not have any interaction with androgenic progestin such as levonorgestrel/Mirena?

It could: The circulating levels of Progesterone secreted by Mirena (levonorgestrel) are very low making androgen side effects possible but uncommon. Spironolactone would decrease the androgenic effects if they were to be present although a doctor would not typically treat Mirena (levonorgestrel) side effects this way. If I were the physician treating someone with androgenic side effects of Mirena (levonorgestrel) I would just change birth control methods ...Read more
