Buy Slynd 4mg tablets

You can buy Slynd as long as it's been approved and prescribed by one of our clinicians.  

Slynd is a progestogen-only contraceptive pill used to prevent pregnancy. However, unlike other mini pills, it contains drospirenone, a hormone typically found in the combined pill.  

This means you're still protected for 24 hours if you forget to take your daily Slynd tabletThat’s longer than the three or 12-hour window provided by norethisterone or desogestrel-based mini pills.  

Slynd also differs from other mini pills by having 24 ‘active’ pills and four placebo pills. These placebo pills allow you to have a withdrawal bleed during that four-day break, without getting out of the rhythm of taking your daily tablet.  

 

How does Slynd work?

Slynd contains the female hormone drospirenone. It works by preventing the release of an egg from the ovaries.  

It also changes the consistency of the cervical mucus, making it harder for sperm to reach the egg, and thins the lining of your uterus, making it more difficult for a fertilised egg to implant.  

Like other hormonal contraceptives, Slynd does not protect you against sexually transmitted diseases (STDs). To protect yourself from STDs and pregnancy, you must also use a barrier method of contraception, such as a condom. 

How effective is Slynd? 

clinical study found that Slynd is 98.2% effective at preventing pregnancy 

If you take Slynd on the first day of your period, your pregnancy prevention will start immediately. 

If you start at any other timeyou’ll need to takSlynd for seven days in a row beforyou’re protected.  

 

Benefits of Slynd 

  • It has a longer missed pill window: Slynd’s 24-hour ‘safe’ window means you’re protected for longer if you forget to take your daily tablet.
  • It contains drospirenone: meaning you can receive some of the benefits of the combined pill while taking a mini pill. It may help reduce bloating, while easing symptoms of PMS, PMDD and PCOS.
  • It’s oestrogen-free: like all mini pills, Slynd doesn’t contain oestrogen, meaning you can take it if you’re breastfeeding or have high blood pressure.

 

How to take Slynd

Each Slynd blister contains 24 white active tablets and four green placebo tablets. The tablets are arranged in order.  

  1. 1. Take one tablet daily with water. Start by taking the first white tablet in the upper left corner, following the direction of the arrows and numbers on the blister. 

    2. The first tablet should be taken on the first day of your period. You should take the white active tablet for 24 days and then the green placebo tablet for four days. 

    3. You must then start a new pack straight away without a break. 

Always take Slynd exactly as described in the patient information leaflet or as your doctor or Chemist4U clinician has told you. 

If you miss a pill or experience severe diarrhoea or vomiting, please refer to the patient information leaflet for advice, as you may not be fully protected against pregnancy. 

 

Missed pill rules for Slynd 

The missed pill rules for Slynd depend on how many tablets you’ve missed: 

  • If you’ve missed one active (white) pill, you should take the missed pill as soon as possible and then continue taking one tablet a day until you finish the pack.  
  • If you’ve missed two or more active (white) pills, you should take the last missed pill as soon as possible. Continue taking your tablets until the pack is finished, leaving the remaining missed pills in the pack. You should use another form of non-hormonal contraception, like condoms, when having sex for seven days after missing your pills.  
  • If you miss one or more placebo (green) pills, you should skip the missed pills and then continue taking one tablet a day until you finish the pack.  

 

When you can start taking Slynd

When you should start taking Slynd depends on whether you’ve previously been using a different form of contraception, or whether you’ve recently had a baby.  

If you have not used a hormonal contraceptive in the last month 

You can start taking Slynd on the first day of your period, and you'll be protected against pregnancy straight away.  

Changing from a combined pill, vaginal ring or transdermal patch 

You can start taking Slynd on the day after the last active tablet of your previous pill pack. You can also start taking Slynd on the day your vaginal ring or transdermal patch is removed.  

You may also start Slynd at the latest on the day following the usual tablet-, ring-, patch-free break or placebo interval of your previous contraception. However, you need to make sure you use another method of contraception, like condoms, for the first seven days you’re on Slynd 

Changing from another progestogen-only pill (POP)

You can stop taking your current POP any day and start taking Slynd the following day. You will not need to use additional contraception. 

Changing from a progestogen-only injection or implant or a progestogen-releasing intrauterine system (IUS)

You should start Slynd the day when your next injection is due or on the day your implant or your IUS is removed. You will not need to use additional contraception.  

After having a baby

You can start taking Slynd between days 21-28 after giving birth. If you begin after day 28 but before your period has returned, you must make sure you are not pregnant before starting the tablets. You must also use a condom for the first seven days.
