Slynd 4mg - Available Online
Slynd 4mg is an innovative oestrogen-free contraceptive pill that combines flexibility with reliability. It is designed for those who need, or would prefer, to avoid taking oestrogen for health or personal reasons.
It contains a female hormone (progestogen) called drospirenone and provides greater flexibility than similar contraceptive pills with a 24-hour missed pill window.
Slynd prevents pregnancy by thickening cervical mucus and thinning the lining of the womb (the endometrium). This prevents the ovary from releasing an egg while also impeding the progress of sperm, making it harder for them to reach and fertilise an egg.
As long as the dosage guidelines are properly followed, Slynd is proven to be 98% effective in preventing pregnancy.
Each pack contains 24 active white tablets (containing drospirenone) and 4 inactive green tablets.
If you'd like to order Slynd, you’ll need a quick, easy and 100% confidential consultation first. This is so that we can make sure that Slynd is a safe and appropriate product for your body's unique needs.

Slynd 4mg Details
Slynd 4mg is a progestogen-only contraceptive pill that is proven to be 98% effective when taken properly.
Its active ingredient is a female hormone called drospirenone, and it is 100% oestrogen-free. As such, it is a suitable option for anyone who is breastfeeding, is a smoker, is at risk of blood clots, or has been advised to avoid oestrogen for health reasons.
Within each pack are enough pills for a 28-day cycle, with 24 active white tablets and four inactive green tablets.
How Does It Work?
Slynd has a triple-action approach to contraception, using the following mechanisms to provide effective contraception without estrogen.
- stopping ovulation
- thickening cervical mucus to create a barrier for sperm
- thinning the lining of the womb to prevent implantation
This triple-action approach differs from traditional progestogen-only contraceptive pills that don't necessarily inhibit ovulation.
How To Take/Use Slynd
Take one tablet with water every day at the same time for 28 consecutive days, taking first the 24 white active tablets and then the four green inactive tablets.
If you forget to take your daily pill at the usual time, take the missed pill as soon as you remember and take the next pill at the usual time. You can even do this if it means taking two pills at once. This is because Slynd has a 24-hour missed pill window.
If the missed pill is taken outside the 24-hour window, take the missed tablet as soon as you remember to, even if it means taking two tablets at the same time, and use an additional method of contraception (e.g. a condom) for the next seven
days.
Use the stickers provided in the pack to easily track which pills you have taken.

- Loss of kidney function
- Breast cancer

- Fungal or bacterial infections
- Angina or irregular heartbeats
Grapefruit and grapefruit juice can also interact with Slynd, making it less effective. Therefore, these should be avoided the entire time you are taking Slynd.
Please note that while Slynd offers effective contraceptive protection, it does not prevent the spread of sexually transmitted infections (STIs).
Is Slynd 4mg Different From Other Birth Control Pills?
Slynd is different from other contraceptive pills in that it is 100% oestrogen-free. It also offers greater flexibility than other mini-pills with a 24-hour missed pill window compared to the three hour window offered by similar pills. It features a 24/4 dosing schedule similar to combined pills, with 24 active pills and four inactive pills for each cycle. This makes it easy to maintain a consistent dosage schedule.
Moreover, it provides a triple-action approach to contraception and inhibits ovulation, unlike similar progestogen-only pills.
How Effective Is Slynd At Preventing Pregnancy?
Provided it is taken properly, Slynd's triple action approach makes it 98% effective at preventing pregnancy. However, four in 100 women may become pregnant in the first year of use. For added protection, a form of barrier contraception (e.g. condoms) is recommended.
In order to ensure that Slynd is as effective as possible, it is important to maintain a consistent dosing schedule - this means taking your pill at the same time every day.
Some medications can make Slynd less effective. Speak to your doctor or pharmacist before taking Slynd.
Can I Take Slynd While Breastfeeding?
Slynd is safe to take while breastfeeding, and because it is oestrogen-free it does not affect your milk supply. While some drospirenone is transferred to your baby through the breastmilk, this is minimal and considered harmless.
You should start taking Slynd 21-28 days after childbirth.
What Happens If I Miss A Slynd 4mg Pill?
If you forget to take a Slynd pill, take the missed pill as soon as you remember to and take the next pill at the usual time. This may require you to take two pills at once.
If the missed pill is taken outside the 24-hour window, take the missed tablet as soon as you remember to, even if it means taking two tablets at the same time, and use an additional method of contraception for the next seven days.
Always follow the pack instructions to ensure a regular dosing schedule.
Will Slynd 4mg Affect My Periods?
While Slynd offers better cycle control than other progestogen-only pills, some people may experience changes in their menstrual patterns including irregular bleeding, spotting, lighter periods or no bleeding at all.
Consult a medical professional as soon as possible if you experience irregular heavy bleeding.
Can Slynd Cause Weight Gain?
Many people are concerned about weight gain when taking any form of hormonal birth control.
Drospirenone, the active ingredient in Slyund, has mildly diuretic properties. This may result in less weight gain from fluid retention when compared to other mini-pills.
During clinical trials, only 0.3%-1.2% of participants experienced weight gain. However, your individual response may vary.
Are There Any Medications That Interact With Slynd?
Some medications can interact with Slynd in different ways, including reducing its effectiveness as a contraceptive or causing unexpected bleeding.
Common examples include:
- Potassium-affecting drugs for heart conditions
- Antifungals
- HIV medications
- Clarithromycin for bacterial infections
- Epilepsy drugs
- Herbal supplements like St. John's Wort
Always check with our clinician team before taking Slynd if you take any other medications. If you need to take additional medications on a short-term basis, additional contraception should be used until the course of treatment is finished.
Can Slynd Help With Acne Or Other Hormonal Issues?
Drospirenone, the active ingredient in Slynd, has anti-androgenic properties. As such, it may help some people experiencing hormonal acne or polycystic ovaries (PCOS). It can also help with hormonal bloating. However, your individual effects may vary and some may also experience acne as a side effect.
The primary purpose of Slynd is for use as a contraceptive.
Is Slynd Suitable For Women Over 35 Who Smoke?
Yes, unlike other contraceptive pills that contain oestrogen, Slynd is suitable for smokers over the age of 35.
However, smoking still carries health risks including increased risk of cancer, heart disease, respiratory problems and lasting fertility issues.
