Slinda is a contraceptive whose active substance is drospirenone. It is a synthetic progestin with a pharmacological profile similar to natural progesterone. This contraceptive pill does not contain estrogens along with the progestogen, so it can be used by women who do not tolerate the former.

How is it presented?

Each Slinda blister contains 24 white tablets, which are the active tablets, and 4 green tablets, also called placebo tablets. These placebos do not contain an active ingredient.

Tablets of two different colors are arranged to follow an order and help meet taking contraceptive. Each of the 24 white active tablets contains the required dose of a female sex hormone, the progestogen drospirenone.

How does Slinda work?

This pill provides high contraceptive efficacy . Slinda’s contraceptive effect is based on inhibition of ovulation, changes in cervical mucus, and effects on the endometrium, which becomes thinner.

However, it has a disadvantage, which is that it can cause vaginal bleeding at irregular intervals during treatment. However, you may not have any bleeding .

Being estrogen-free, this new contraceptive is expected to reduce the cardiovascular risks associated with combined hormonal contraceptives.

Drospirenone has antimineralocorticoid properties, which favors less fluid retention. Likewise, it has antiandrogenic properties, ideal for women with signs of acne, hirsutism or oily skin.

Precautions in pregnancy and lactation

Slinda should not be used if you are pregnant or think you might be. The use of Slinda before pregnancy has not shown an increased risk of the appearance of birth defects, however, the appearance of adverse effects cannot be ruled out.

This contraceptive, on the other hand, can be used during lactation . Although no effects are expected on newborns, small amounts of drospirenone are excreted in breast milk.

How to  take Slinda

This pill offers good cycle control thanks to its 24 + 4 administration scheme. It is ideal to guarantee adherence to treatment and compliance with it.

By presenting 24 active pills and 4 inactive tablets, you have the advantage of having a programmed or predictable bleeding pattern , and minimal losses between two periods.

Take one tablet each day at the same time, with or without food. To keep order, follow the direction of the arrows and the sequence of numbers on the blister. To start, you should take the first tablet on the first day of menstrual bleeding, and continue with the rest in the order of 24 days.

Then take the four placebo tablets and start a new container again, leaving no rest day.

You may or may not have some bleeding while taking Slinda, but you should continue taking the tablets without interruption. If you take the contraceptive well, you will even be protected during the four days that you take the placebo.

The tracking of the shots is marked by arrows or the names of the days of the week on the packaging

How to start with the first pack of Slinda

If you have not taken any hormonal contraceptive in the previous month, start on the first day of your period. If you do so, you will be immediately protected from pregnancy and you will not need to use additional measures with barrier methods.

However, if you have been taking another oral contraceptive or using the vaginal ring or transdermal patch, you should start taking Slinda the day after the last active tablet of your previous contraceptive or the same day that the vaginal ring or transdermal patch was removed.

However, you can also start taking Slinda the day after the week of rest without tablets, vaginal ring, patch or placebo period, from your previous contraceptive. In these cases, it is necessary that you use an additional barrier contraceptive method during the 7 days after taking Slinda.


This contraceptive has only drospirenone in its composition and is free of estrogens. It offers effective and safe contraceptive protection, without compromising future fertility, reducing the side effects associated with estrogens.
