Difference Between Nikki And Gianvi

Buima asked

What are the differences between Gianvi and Nikki?

Answer

BC Pill PacksNikki and Gianvi contain the same active ingredients, in the same amounts (ethinyl estradiol 0.02mg and drospirenone 3mg). They are both indicted to prevent pregnancy as well as treat acne vulgaris and premenstrual dysphoric disorder (PMDD).  Nikki and Gianvi are considered equivalent generic products to the brand name Yaz and can be switched between one another as well as other brand names containing the same active ingredients (e.g. Vestura and Loryna).

Some pharmacies will switch to carrying different brand names of birth control pills and will switch between them depending on what they have in stock. This is fine as long as they have the same amount of active ingredients, are considered bioequivalent, and the doctor does not specify they cannot be switched.

It is important to note that while the active ingredients are the same for both Nikki and Gianvi, they do have different inactive ingredients, which is why the tablets look different.

Information About Ethinyl Estradiol / Drospirenone

The two hormones ethinyl estradiol and drospirenone are contained in these combination pills and are used to prevent pregnancy. They are also indicted for the treatment of acne and PMDD. These pills do not prevent sexually transmitted infections (STIs).

How It Works

Birth control pills mostly work by preventing ovulation by maintaining steady hormone levels in the body. However, other changes to the cervical mucus a lining of the uterus can also help. Changes in cervical mucus can make it difficult for sperm to enter the uterus, and a change in the lining of the uterus would reduce the change of implantation.

Drospirenone is a unique progestin and is considered a "fourth-generation" progestin. It is similar to spironolactone and has both antimineralocorticoid and antiandrogenic properties. In addition to contraceptive use, drospirenone can reduce acne as well as alleviate premenstrual complaints, such as:

  • Negative mood
  • Water retention
  • Increased appetite

Both Nikki and Gianvi also contain 24 active pills, as opposed to the more commonly seen 21 active pill regimens. The extra 3 days of active pills are thought to help reduce premenstrual symptoms.
