Your Doctor has
Prescribed ADDYI

This is Addyi® A Little Pink Pill* * Not actual size


ADDYI is used for the treatment of pre and naturally postmenopausal women, aged 60 years or younger, 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 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?

There is one medicinal ingredient: flibanserin. The non-medicinal ingredients are: croscarmellose sodium, hypromellose, 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?

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.

How to take and store ADDYI

  • Take ADDYI exactly as your doctor tells you to: one tablet, once-a-day, and only at bedtime.
  • Do not take more than the dose prescribed by your doctor.
  • 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.  Ask your doctor or pharmacist on how to safely throw away ADDYI tablets.

Are there any reasons why ADDYI should not be taken?

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 under 18 years old
  • you are over 60 years old
  • you take a drug called digoxin or a similar type of drug
  • 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 precautions

  • ADDYI can cause severe low blood pressure and fainting.
  • Take ADDYI at bedtime. If you take ADDYI and feel lightheaded or dizzy, lie down right away. Drinking alcohol close to the time you take ADDYI increases your risk of severe low blood pressure and fainting.
  • ADDYI can cause sedation or make you feel very drowsy. After taking ADDYI, do not drive or perform other activities that require full attention until you know how it affects you. Using ADDYI with depressant drugs may increase the risk of sedation or drowsiness.
  • If you have liver problems, you should not take ADDYI.
  • Before taking ADDYI, tell your healthcare professional about all the medicines you take, including drugs, vitamins, minerals, natural supplements, or alternative medicines. They will tell you if it is safe to take ADDYI.

Other warnings you should know about

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 pregnant or trying to become pregnant
  • if you are breastfeeding 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
  • if you have experienced allergic reactions or sensitivity to any medicines

The effects of ADDYI were not studied in Black or Asian women who are postmenopausal, or postmenopausal women who are underweight.

If you weigh less than 50 kg, there might be a higher risk of certain side effects, including central nervous system depression (sedation or feeling very sleepy), low blood pressure and fainting. Tell your healthcare professional right away if you feel these effects.

If you drink alcohol, wait at least 2 hours after drinking 1 or 2 standard alcoholic drinks* before taking ADDYI at bedtime. If you drink 3 or more standard alcoholic drinks in the evening, skip your ADDYI dose at bedtime. After you have taken your ADDYI at bedtime do not drink alcohol until the following day.

ADDYI can cause low blood pressure, fainting (loss of consciousness) and sleepiness. Using ADDYI with drugs (like diphenhydramine, opioids, hypnotics and benzodiazepines) that slow down your central nervous system can increase this risk. 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.

Anaphylactic reactions (severe allergic reactions) may happen while taking ADDYI. Tell your doctor right away if you have a hard time breathing or a serious rash.

* Examples of 1 standard alcoholic drink include: one 12-ounce regular beer (5% alcohol); 5 ounces of wine (12% alcohol); 1.5 ounces of distilled spirits or shot (40% alcohol).
