Adempas contains the active substance riociguat, a guanylate cyclase (sGC)-stimulator.
It is used to treat adults and children from 6 years of age with certain types of pulmonary hypertension:
- Chronic thromboembolic pulmonary hypertension (CTEPH).
Adempas is used to treat adult patients with CTEPH. In patients with CTEPH, the blood vessels of the lung are blocked or narrowed by blood clots. The medicine can be used in patients with CTEPH who cannot be operated on, or in patients in whom pulmonary hypertension remains or returns after surgery. - Pulmonary arterial hypertension (PAH).
Adempas is used to treat adults and children aged 6 years or older with pulmonary arterial hypertension. In these patients, the walls of the blood vessels of the lungs are thickened and the vessels become narrowed. In patients with PAH, Adempas is taken together with certain other medicines (so-called endothelin receptor antagonists). In adults, the medicine can also be taken on its own (monotherapy).
In patients with pulmonary hypertension, the blood vessels that carry blood from the heart to the lungs become narrowed, making it harder for the heart to pump blood to the lungs, and leading to high blood pressure in the vessels. Because the heart must work harder than normal, people with pulmonary hypertension feel tired, dizzy and short of breath. Adempas widens the blood vessels that lead from the heart to the lungs, reducing symptoms of the disease and better allowing patients to carry out physical activity better.
- take PDE5 inhibitors such as sildenafil, tadalafil, vardenafil. These are medicines to treat high blood pressure in lung arteries or erectile dysfunction.
- have severely reduced liver function.
- are allergic to riociguat or any of the other ingredients of this medicine (listed in section 6).
- are pregnant.
- take nitrates or nitric oxide donors such as amyl nitrite. These are medicines often used to treat high blood pressure, chest pain or heart disease. This also includes recreational drugs called poppers.
- take other medicines similar to Adempas called soluble guanylate cyclase stimulators, such as vericiguat. Ask your doctor if you are not sure.
- have low blood pressure before you take Adempas the first time. To start with Adempas your systolic blood value should be
- 90 mmHg or more if your age is between 6 and 12 years,
- 95 mmHg or more if you are 12 years old or older.
- have increased blood pressure in your lungs associated with scarring of the lungs, of unknown cause called idiopathic pulmonary pneumonia.
If any of these apply to you, talk to your doctor first and do not take Adempas.
Talk to your doctor or pharmacist before taking Adempas if you
- have pulmonary veno-occlusive disease, a disease which makes you feel short of breath because fluid builds-up in the lungs. He or she may decide to provide you with an alternative medicine.
- have recently had serious bleeding from the lungs and airways.
- have undergone treatment to stop coughing up blood (bronchial arterial embolisation).
- take medicines that prevent the blood from clotting since this may cause bleeding from the lungs. Your doctor will regularly test your blood and measure blood pressure.
- The doctor may decide to monitor the blood pressure, if you
- have symptoms of low blood pressure like dizziness, lightheadedness or fainting, or
- take medicines to lower blood pressure or to increase urination, or
- have heart or circulation problems
- are older than 65 years as low blood pressure is more likely in this age group.
Inform your doctor if
- you are on dialysis or if the kidneys do not work properly, as use of this medicine is not recommended.
- your liver does not work properly.
While using Adempas, talk to your doctor if you
- feel short of breath during treatment with this medicine. This can be caused by a build-up of fluid in the lungs. If this is due to pulmonary veno-occlusive disease your doctor may stop treatment with Adempas.
- start or stop smoking during treatment with this medicine, because this may influence the level of riociguat in your blood.
- Chronic thromboembolic pulmonary hypertension (CTEPH)
- Adempas is not recommended for use in CTEPH patients less than 18 years of age.
- Pulmonary arterial hypertension (PAH)
- You have been prescribed Adempas tablets. For PAH patients of 6 years and older that weigh less than 50 kg, Adempas is also available as granules for oral suspension.
Patients may switch between tablets and oral suspension during therapy due to body weight changes.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, in particular:
- Do not take medicines used for
- high blood pressure or heart disease such as nitrates and amyl nitrite, or another soluble guanylate cyclase stimulator such as vericiguat. Do not take these medicines together with Adempas.
- high blood pressure in lung arteries, as you must not take certain medicines such as sildenafil, tadalafil together with Adempas. Other medicines for high blood pressure in the lung arteries, such as bosentan and iloprost, can be used with Adempas, but you should inform the doctor.
- erectile dysfunction such as sildenafil, tadalafil, vardenafil. Do not take these medicines together with Adempas.
- The following medicines can increase the level of Adempas in the blood which increases the risk of side effects
- fungal infections such as ketoconazole, posaconazole, itraconazole

Treatment should only be started by a doctor experienced in the treatment of high blood pressure in lung arteries, who will monitor you during treatment. During the first weeks of treatment your doctor will need to measure your blood pressure at regular intervals. Adempas is available in different strengths and by checking your blood pressure regularly at the beginning of your treatment, your doctor will ensure that you are taking the appropriate dose.
Your doctor will tell you what dose of Adempas to take.
- Treatment usually starts with a low dose.
- Your doctor will slowly increase your dose depending on how you respond to the treatment.
- During the first weeks of treatment the doctor will need to measure your blood pressure at least every two weeks. This is required to decide on the correct dose of your medicine.
Adempas is for oral use. The tablets should be taken 3 times a day, every 6 to 8 hours.
Crushed tablets:
If you have difficulty swallowing the whole tablet, talk to your doctor about other ways to take Adempas. The tablet may be crushed and mixed with water or a soft food immediately before you take it.
The recommended starting dose is a 1-mg tablet taken 3 times a day for 2 weeks.
Your doctor will increase the dose every 2 weeks to a maximum of 2.5 mg 3 times a day (maximum daily dose of 7.5 mg) unless you experience very low blood pressure. In this case, your doctor will prescribe you Adempas at the highest dose you are comfortable on. The best dose will be selected by your doctor. For some patients lower doses 3 times a day might be sufficient.
You may be at greater risk of low blood pressure. Your doctor may adjust the dose.
If you smoke, it is recommended that you stop before starting treatment, as smoking may reduce the effectiveness of these tablets. Please tell your doctor if you smoke or stop smoking during treatment. Your doctor may need to adjust your dose.
Please contact the doctor if you took more Adempas than you should and if you notice any side effects (see section 4). If your blood pressure drops (which can make you feel dizzy) then you may need immediate medical attention.

Do not stop taking this medicine without talking to your doctor first. If you stop taking this medicine, your disease may worsen. If you have not taken this medicine for 3 days or more, please tell your doctor before you start taking it again.

- If you switch to Adempas
- do not start Adempas for at least 24 hours after your last dose of sildenafil and at least 48 hours after your last dose of tadalafil.
