Adcirca – Tadalafil uses, dose and side effects


20 mg film-coated tablets

1. What ADCIRCA is and what it is used for

ADCIRCA contains the active substance tadalafil.

ADCIRCA belongs to a group of medicines called phosphodiesterase type 5 inhibitors (PDE5), which improve the blood flow to the lungs by affecting the blood vessels around the lungs so that they relax. The result is improved capacity during physical exertion.

ADCIRCA is a treatment for pulmonary arterial hypertension in adults.

2. What you need to know before taking ADCIRCA

Do not take ADCIRCA if you

– is allergic to tadalafil or any of the other ingredients (see section 6).

– Take medicines containing nitrates, such as amyl nitrite, which are used to treat chest pain. ADCIRCA has been shown to increase the efficacy of these drugs. If you are taking any form of nitrate or are unsure, talk to your doctor.

– has ever before lost sight – a condition called “stroke in the eye” (non-arteritic anterior ischemic optic neuropathy – NAION).

– has had a heart attack in the last 3 months.

– has low blood pressure.

– tar riociguat. This medicine is used to treat pulmonary arterial hypertension (ie high blood pressure in the lungs) and chronic thromboembolic pulmonary hypertension(ie high blood pressure in the lungs due to blood clots). PDE5 inhibitors, such as ADCIRCA, have been shown to increase the antihypertensive effect of this medicine. If you are taking riociguat or if you are not sure, talk to your doctor.
