Why ADDYI?1,2

ADDYI is used for the treatment of premenopausal women with hypoactive sexual desire disorder (HSDD), a condition that has been medically recognized for nearly half a century. It is the most common form of female sexual dysfunction, so you are not alone.

It is prescribed when a woman has had low sexual desire, 75-100% of the time, for a minimum of 6 months, and when the situation causes her difficulty in her relationship. The low sexual desire must not be a result of some other condition (medical or psychological), problems in a relationship, or effects of a medication or other drug substance.

To make sure that none of these factors play a role in your diagnosis, and that ADDYI is right for you, before prescribing, your doctor may have used a checklist that includes a number of questions.

ADDYI cannot be prescribed for everyone. It is prescribed only for women:
• who have not yet gone through or even started menopause,
• who have not had problems with low sexual desire in the past, and
• who have low sexual desire regardless of the type of sexual activity, situation, or sexual partner.

What are the ingredients in ADDYI?1

There is one medicinal ingredient: flibanserin. The non-medicinal ingredients are: croscarmellose sodium, hydromellose, iron oxide red, lactose monohydrate, macrogol, magnesium stearate, microcrystalline cellulose, talc, titanium dioxide.

ADDYI is available in the form of a 100 mg tablet.

How does ADDYI work?1

First of all, it is important to understand what ADDYI does not do. It does not improve sexual performance.

ADDYI is a medicine that adjusts chemicals in your brain. These chemicals, called dopamine and serotonin, are involved in sexual interest and desire. The exact way that ADDYI works, however, is not known.

Are there any reasons why ADDYI should not be taken?1

Do not use ADDYI if:

  • you are allergic to flibanserin, or any of the other ingredients in ADDYI
  • you have liver problems
  • you are pregnant or breastfeeding
  • you have low blood pressure and you drink alcohol
  • you are a man
  • you are going through menopause or have gone through menopause
  • you are under 18
  • you take certain other medicines that can increase the amount of ADDYI in your blood because that can cause severe low blood pressure, fainting (loss of consciousness) and sleepiness

To ensure that ADDYI is safe for you to take, before taking ADDYI, tell your doctor about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.

Serious warnings and precautions1

Drinking alcohol while taking ADDYI can increase your risk of getting severe low blood pressure and fainting. You should be careful if you drink alcohol while taking ADDYI and limit how much alcohol you drink. If you have low blood pressure you should never drink alcohol while taking ADDYI.

If you have liver problems, you should not take ADDYI.

Other warnings you should know about1

To help avoid side effects and to ensure proper use, before taking ADDYI, talk to your doctor about any health conditions or problems you may have, including:

  • low blood pressure or any medical condition that can cause low blood pressure
  • heart problems
  • if you are trying to become pregnant or planning to breastfeed
  • if you drink alcohol
  • if you have been told that you have a variation in a liver enzyme called CYP2C19 which makes you process certain medicines poorly

ADDYI can cause low blood pressure, fainting (loss of consciousness) and sleepiness. This can affect your ability to drive or use machines. You should wait at least 6 hours after taking ADDYI before driving or using machines. You should be extra careful when driving the morning after taking ADDYI until you know how it affects you.

The risk of low blood pressure and fainting is increased if ADDYI is taken during waking hours, or if more than the recommended amount is taken. This is why you must take ADDYI at bedtime only, and exactly as your doctor tells you to. If you take ADDYI and feel lightheaded or dizzy, lie down right away. Get immediate medical help if the symptoms do not go away, or ask someone to get immediate medical help for you should you faint (lose consciousness). If you have fainted after using ADDYI, tell your doctor as soon as you can.

How to take and store ADDYI1

Take ADDYI exactly as your doctor tells you to: one tablet, once-a-day, and only at bedtime.

Never take ADDYI at another time of the day. If you take ADDYI at a time other than bedtime you might get low blood pressure, faint (lose consciousness), get very sleepy and possibly injure yourself by accident.

Talk to your doctor if your symptoms of HSDD have not gotten better after taking ADDYI for 8 weeks.

If you miss a dose of ADDYI, simply take your next dose at bedtime the next day. Do not take ADDYI the next morning. Do not double your next dose.

If you think you have taken too much ADDYI, contact your doctor, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.

Store ADDYI at 15-30°C. Keep out of reach and sight of children.
