• take PDE5 inhibitors (e.g. sildenafil, tadalafil, vardenafil). These are medicines used to treat high blood pressure in the arteries of the lungs (PAH) or erectile dysfunction.
• have severe liver problems (severe hepatic impairment).
• 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) in any form, 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 (soluble guanylate cyclase stimulators, such as vericiguat). Ask your doctor if you are not sure.
• have low blood pressure (systolic blood pressure: in children aged 6 to < 12 years below 90 mmHg, in patients ≥ 12 years below 95 mmHg) before starting first treatment with this medicine.
• have increased blood pressure in your lungs associated with scarring of the lungs, of unknown cause (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 recently had serious bleeding from the lung.
• have undergone treatment to stop coughing up blood (bronchial arterial embolisation).
• take blood-thinning medicines (anticoagulants) since this may cause bleeding from the lungs. Your doctor will regularly test your blood and measure blood pressure.
• feel short of breath, this can be caused by a build-up of fluid in the lungs. Talk to your doctor if this happens.
• have any symptoms of low blood pressure (hypotension) such as dizziness, lightheadedness, or fainting or if you are taking medicines to lower your blood pressure or medicines that cause an increase in urination or if you have problems with your heart or circulation. Your doctor may decide to monitor your blood pressure. If you are older than 65 years, you have an increased risk of developing low blood pressure.
• take medicines used to treat fungal infections (e.g. ketoconazole, posaconazole, itraconazole) or medicines for the treatment of HIV infection (e.g. abacavir, atazanavir, cobicistat, darunavir, dolutegravir, efavirenz, elvitegravir, emtricitabine, lamivudine, rilpivirine, ritonavir, and tenofovir). Your doctor will monitor your health status and should consider a lower starting dose for Adempas.
• are on dialysis or if your kidneys do not work properly (creatinine clearance < 30 ml/min) the use of this medicine is not recommended.
• have moderate liver problems (hepatic impairment).
• start or stop smoking during treatment with this medicine, because this may influence the level of riociguat in your blood.

The use of Adempas tablets in children under 6 years and adolescents below 50 kg of weight should be avoided. Efficacy and safety have not been established in the following paediatric populations:

• Children aged < 6 years because of safety concerns.
• Children with PAH with too low blood pressure:
  • aged 6 to < 12 years < 90 mmHg at treatment initiation.
  • aged 12 to < 18 years <95 mmHg at treatment initiation.
• Children and adolescents with other forms of this disease, i.e. CTEPH, if aged < 18 years old.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, in particular, medicines used for:

• high blood pressure or heart disease (such as nitrates and amyl nitrite in any form or other soluble guanylate cyclase stimulator (such as vericiguat)). You must not take those medicines together with Adempas.
• high blood pressure in the lung vessels (the pulmonary arteries), as you must not take certain medicines (sildenafil and tadalafil) together with Adempas. Other medicines for high blood pressure in the lung vessels, such as bosentan and iloprost, can be used with Adempas, but you should still tell your doctor.
• erectile dysfunction (such as sildenafil, tadalafil, vardenafil), as you must not take those medicines together with Adempas.
• fungal infections (such as ketoconazole, posaconazole, itraconazole) or HIV infection (such as abacavir, atazanavir, cobicistat, darunavir, dolutegravir, efavirenz, elvitegravir, emtricitabine, rilpivirine or ritonavir). Alternative treatment options may be considered. If you already take one of these medicines and start treatment with Adempas, your doctor will monitor your health status and should consider a lower starting dose for Adempas.
• epilepsy (e.g. phenytoin, carbamazepine, phenobarbitone).
• depression (St. John’s Wort).
• preventing rejection of transplanted organs (ciclosporin).
• joint and muscular pain (niflumic acid).
• cancer (such as erlotinib, gefitinib).
• stomach disease or heartburn (antacids such as aluminium hydroxide/magnesium hydroxide). These medicines should be taken at least 2 hours before or 1 hour after taking Adempas.
• nausea, vomiting (feeling or being sick) (such as granisetron).

If you smoke, it is recommended that you stop, as smoking may reduce the effectiveness of these tablets. Please tell your doctor if you smoke or stop smoking during treatment. A dose adjustment might be required.

Women and female adolescents of childbearing potential must use effective contraception during treatment with Adempas.

Pregnancy

Do not take Adempas during pregnancy. You are also advised to take monthly pregnancy tests. If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Breast-feeding

If you are breast-feeding or planning to breast-feed, ask your doctor or pharmacist for advice before taking this medicine because it might harm your baby.

Adempas moderately influences the ability to cycle, drive and use machines. It may cause side effects such as dizziness. You should be aware of the side effects of this medicine before cycling, driving or using machines (see section 4).

If you have been told by a doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

This medicine contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially “sodium free”.

The recommended starting dose is a 1-mg tablet taken 3 times a day for 2 weeks.

The tablets should be taken 3 times a day, every 6 to 8 hours. They can generally be taken with or without food.

However, if you are prone to having low blood pressure (hypotension), you should not switch from taking Adempas with food to taking Adempas without food because it may affect how you react to this medicine.

During the first weeks of treatment your doctor will need to measure your blood pressure at least every two 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.

Special considerations for patients with kidney or liver problems

Tell your doctor if you have kidney or liver problems. Your doctor may adjust the dose. If you have severe liver problems, do not take Adempas.

65 years or older

If you are 65 years or older your doctor will take extra care in adjusting your dose of Adempas, because you may be at greater risk of low blood pressure.

Special considerations for patients who smoke

Tell your doctor if you start or stop smoking during treatment with this medicine. Your doctor may adjust the 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 take a double dose to make up for a forgotten dose. If you miss a dose, continue with the next dose as planned.

Do not stop taking this medicine without talking to your doctor first, because this medicine prevents the progression of the disease. If you stop to take this medicine for 3 days or longer, please tell your doctor before restarting taking this medicine.
