Consumer:

Riociguat may add to the blood pressure lowering effects of metOLazone. You may experience headache, dizziness, lightheadedness, fainting, and/or changes in pulse or heart rate. Let your doctor know if you develop these symptoms and they do not go away after a few days or they become troublesome. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Professional:

MONITOR: Riociguat may potentiate the action of antihypertensive agents and other vasodilators. Symptomatic hypotension may occur. Riociguat stimulates soluble guanylate cyclase (sGC), an enzyme in the cardiopulmonary system that binds with nitric oxide (NO) to catalyze the synthesis of cyclic guanosine monophosphate (cGMP). The resultant accumulation of cGMP in vascular smooth muscle cells leads to peripheral vasodilation and blood pressure decreases.

MANAGEMENT: Caution is advised if riociguat is prescribed in combination with antihypertensive agents or other vasodilators. A reduction in the starting dosage of riociguat to 0.5 mg three times a day should be considered for patients who may not tolerate the hypotensive effect of riociguat. Periodic systemic blood pressure monitoring is recommended. If systolic blood pressure remains greater than 95 mmHg and the patient has no signs or symptoms of hypotension, the dosage may be increased by 0.5 mg three times a day every 2 weeks as tolerated, up to a maximum of 2.5 mg three times a day. If hypotension develops at any time during treatment, the dosage should be reduced by 0.5 mg three times a day.
