What is Adempas?
Adempas (riociguat) lowers blood pressure in your lungs, helping your heart pump blood more efficiently.
Adempas is used to treat chronic thromboembolic pulmonary hypertension (CTEPH) in people who cannot be treated with surgery, or in people who have undergone surgery but still have symptoms. Riociguat can treat certain symptoms of CTEPH and can improve your ability to exercise.
Adempas is used to treat pulmonary arterial hypertension (PAH). Riociguat can improve your ability to exercise and help prevent PAH from getting worse.
Adempas is available to women only under a special program from a certified pharmacy. You must be registered in the program and understand the risks and benefits of taking this medication.
Adempas is available to women only under a special program from a certified pharmacy. You will need to have a negative pregnancy test before starting this treatment.

Tell your doctor about all your current medicines and any you start or stop using. Many drugs can interact with riociguat, and some drugs should not be used together.
Before taking this medicine
You should not use Adempas if you are allergic to riociguat, or if:
you are pregnant or might become pregnant during treatment; or
you have PAH related to a condition called idiopathic interstitial pneumonias (PH-IIP).
Some medicines can interact with riociguat and should not be used at the same time. Your doctor may need to change your treatment plan if you use any of the following drugs:
erectile dysfunction medicine such Viagra, Cialis, Levitra, and others;
a nitrate drug for chest pain or heart problems (amyl nitrite, nitroglycerin, and others); or
other medicines to treat PAH (Adcirca or Revatio).
Do not take Adempas within 24 hours before or after taking sildenafil (Revatio, Viagra), or within 24 hours before or 48 hours after taking tadalafil (Adcirca, Cialis).
To make sure Adempas is safe for you, tell your doctor if you have:
heart disease, blood circulation problems;
low blood pressure;
a condition called pulmonary veno-occlusive disease (PVOD);
a recent history of coughing up blood or bleeding from your lung;
kidney disease (or if you are on dialysis);
if you smoke; or
if you are dehydrated.
Do not use Adempas if you are pregnant. It could harm the unborn baby or cause birth defects. Use effective birth control to prevent pregnancy while you are using this medicine and for at least 1 month after your treatment ends. Tell your doctor right away if you miss a menstrual period or think you may have become pregnant during treatment.
You will need to have a negative pregnancy test before starting this treatment. You will also be re-tested every month during your treatment, and 1 month after you stop taking this medicine. Do not have unprotected sex.
Even if you are not planning a pregnancy, you are considered able to become pregnant if:
you have entered puberty (even if you have not yet started having periods);
you have never had a hysterectomy or had your ovaries removed; or
you have not gone through menopause (you have never gone 12 months in a row without a menstrual period).
While taking Adempas, girls and women who are able to get pregnant must use highly effective birth control, or two methods together.
A tubal ligation alone is an effective birth control method.
An intrauterine device (IUD) or birth control implant alone are also effective birth control methods.
If you use birth control pills, injections, skin patches, or vaginal rings, you must use a back-up barrier form of birth control, such as a condom or diaphragm or cervical cap. Always use a spermicide gel or insert together with a barrier form of birth control.
If you use only a barrier method, you must use a second barrier method as a back-up. For example, use a diaphragm or cervical cap in addition to a condom, plus a spermicide gel or insert.
If your sexual partner has had a vasectomy, you must still use a second method of birth control--either a barrier method or a hormonal form (birth control pills, injections, skin patch, or vaginal ring).
Adempas comes with patient instructions about acceptable forms of birth control to use while taking this medicine. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
If you are the parent or caregiver of a female child taking this medication, talk to the child's doctor once you notice any signs of puberty (breast development or pubic hair), even if menstrual periods have not yet begun.
It is not known whether riociguat passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
