Dianette contains both an oestrogen and an anti-androgen.  Androgens are the hormones that stimulate hair growth and the grease glands in your skin. Sometimes these grease glands can get blocked as they produce too much sebum, the blocked glands can then get infected and become inflamed which leads to acne spots. More information

Acne and Hirsutism (excessive hairiness) can both be really hard to live with. Like any skin condition, they are very visible and can really affect the person’s self-confidence. Acne is very common, often appearing in teenagers and affecting the face back and chest. Hirsutism affects around 10% of western women and is more common in those of the Mediterranean or Middle-Eastern origin. These skin conditions can be completely unrelated to one another and both have several treatment options, from lifestyle changes to topical treatments and beyond. In fact, both can be treated with Dianette an oral contraceptive pill also known as Diane, but only when the benefits of such a treatment are deemed to outweigh the risks. 

What is Dianette? 

Dianette contains both an oestrogen and an anti-androgen. 

Androgens are the hormones that stimulate hair growth and the grease glands in your skin. Sometimes these grease glands can get blocked as they produce too much sebum, the blocked glands can then get infected and become inflamed which leads to acne spots. 

Dianette works to prevent androgens from acting on your skin and reduces the number of androgens produced which has a positive effect on your skin. 

Dianette comes in the form of a daily pill which you take in line with your menstrual cycle. Each tablet contains 2 milligrams of the anti-androgen, cyproterone acetate, and 35 micrograms of the oestrogen, ethinylestradiol. 

When is Dianette used? 

Dianette is a contraceptive pill that is used to treat a variety of skin conditions including: 

  • acne 
  • very oily skin 
  • excessive hair growth 

Dianette is only used in the following circumstances: 

  • if you are of reproductive age; 
  • if other treatments like topical creams and antibiotics have not improved your condition; 
  • if your doctor considers treatment with a hormonal contraceptive appropriate; 
  • if the benefits are deemed to outweigh the risks. 

Dianette is also a combined oral contraceptive pill however it is only used to treat skin conditions, you cannot take another contraceptive pill while taking Dianette but once your skin condition has cleared up then you should switch to a different oral contraceptive if you want to remain protected from unwanted pregnancy. 

How do you use Dianette? 

As it’s a combined oral contraceptive Dianette is taken on a monthly cycle: 

  • Start taking Dianette on the first day of your period when you are taking it for the first time; 
  • Take one pill every day for 21 days; 
  • Take your pill at the same time every day; 
  • Swallow the pill whole, with or without water; 
  • Follow the arrows on the strip to ensure you take one pill a day; 
  • When you have finished the pack (21 tablets) you will have a seven-day break, during which you will have a breakthrough bleed like a period; 
  • You are still protected from pregnancy on the seven-day break as long as you have taken the tablets correctly every day; 
  • On day eight of the break start a new packet and a new 21-day cycle of pills; 
  • Your doctor will tell you how long to keep taking his medication; 
  • If you are switching from a different 21-day pill start Dianette the day after you finish the previous contraceptive (you will not have a 7-day break until you finish the first strip of Dianette); 
  • If you are switching from a 28-day pill, start taking Dianette on the 29th day. (you will not have a 7-day break until you finish your first strip of Dianette). 

What dosages are there? 

The dose for Dianette is always the same: 

  • One pill a day for 21 days followed by a 7-day break; 

If you forget to take your pill, take it as soon as you remember and then carry on with the remaining pills as normal. 

If you are more than 12 hours late taking your pill or you have missed more than one day: 

  • Take the pill you missed most recently as soon as you remember, even if this means you take two pills at once (don’t take any others that you missed, leave them in the pack); 
  • Continue taking your pills as normal; 
  • If it is less than seven days before you are due a break, do not take a break and start the new packet straight away; 
  • Always use extra contraception for seven days of you miss a pill; 
  • If you miss 1 or more pills from days 1-7 of the cycle you could become pregnant if you do not use an additional method of contraception when having sex.
