Indication

ADCIRCA (tadalafil) is a prescription medication used to treat pulmonary arterial hypertension (PAH) (WHO Group 1) to improve exercise ability. Studies establishing effectiveness included predominately patients with NYHA Functional Class II–III symptoms and etiologies of idiopathic or heritable PAH (61%) or PAH associated with connective tissue diseases (23%).

Important Safety Considerations for ADCIRCA (tadalafil)

You should discuss all of your medical conditions and all medications with your healthcare provider before starting ADCIRCA

Do not take ADCIRCA if you take any medications that contain nitrates (often used for chest pain) or guanylate cyclase stimulators, as the combination could cause a sudden, unsafe drop in blood pressure

Do not take ADCIRCA if you are allergic to tadalafil or any other ingredient in ADCIRCA

ADCIRCA is a type of medication called a phosphodiesterase 5 inhibitor (PDE-5i) that can cause blood vessels to widen, which may result in a decrease in blood pressure. If you have heart-disease or any problems with low blood pressure, tell your healthcare provider before taking ADCIRCA, as these conditions may be affected by the action of ADCIRCA

Talk with your healthcare provider if you are pregnant or planning to become pregnant or if you are breastfeeding or plan to breast feed.

If you have ever had blockage in the veins of your lungs, known as pulmonary veno-occlusive disease (PVOD), ADCIRCA is not recommended for you

Taking ADCIRCA with alcohol, or blood pressure medications, such as alpha-blockers, may lower blood pressure and cause hypotension (light-headedness or fainting)

Do not take ADCIRCA if you are taking rifampin (an antibiotic for certain bacterial infections), or antifungal medications, such as ketoconazole and itraconazole. If you require treatment with both ADCIRCA and ritonavir (Norvir®) at the same time, your dose of ADCIRCA will need to be adjusted. Inform your healthcare provider if you have kidney or liver problems before taking ADCIRCA

ADCIRCA contains the same ingredient (tadalafil) as Cialis®, which is used to treat erectile dysfunction (ED, impotence) and the signs and symptoms of benign prostatic hyperplasia (BPH, enlarged prostate). If you are taking ADCIRCA, do not take Cialis or other PDE-5is

In rare cases, patients reported side effects such as decreased eyesight or loss of vision in one or both eyes (NAION), or sudden decrease or loss of hearing, sometimes with ringing in the ears and dizziness. If you experience any of these side effects after taking ADCIRCA, seek medical attention right away

In rare cases, men taking PDE-5is (including tadalafil) for erectile dysfunction reported side effects such as an erection lasting more than four hours. If you experience a prolonged erection, seek medical attention right away

The most common side effects of ADCIRCA are headache, muscle pain, getting red or hot in the face (flushing), nausea, pain in the arms, legs or back, upset stomach, stuffy or congested nose

What is Remodulin?

Remodulin is a prescription medication used to treat adults with pulmonary arterial hypertension (PAH; WHO Group 1), which is high blood pressure in the arteries of your lungs. Remodulin can reduce symptoms associated with exercise. Remodulin was studied mainly in patients with NYHA Functional Class II-IV symptoms. It is not known if Remodulin is safe and effective in children.

In people with PAH who need to switch from epoprostenol, Remodulin is approved to slow the worsening of symptoms.

Important Safety Information for Remodulin

Before you take Remodulin, tell your healthcare provider if you:

  • Have other medical conditions or take other medicines that may affect your use of Remodulin by increasing the risk of side effects or decreasing the drug’s effectiveness.
  • Have liver or kidney problems. Your Remodulin dose may need to be adjusted if you have liver problems.
  • Have low blood pressure or bleeding problems.
  • Are taking gemfibrozil (for high cholesterol), rifampin (for infection) or other drugs that affect liver enzymes. Your doctor may need to adjust your Remodulin dosage.
  • Are pregnant, breastfeeding, or planning to become pregnant. It is not known if Remodulin will harm your unborn baby or if Remodulin passes into your breast milk.

What are the serious side effects of Remodulin?

  • Continuous intravenous (IV) infusions of Remodulin delivered using an external infusion pump, with a tube placed in a central vein within the chest, are associated with the risk of blood stream infections and sepsis, which may be fatal. Therefore, continuous subcutaneous (SC) infusion delivered just beneath the skin is the preferred type of delivery.
  • Worsening of PAH symptoms. Do not stop taking or greatly reduce your Remodulin dose without consulting your doctor.
  • Low blood pressure (symptomatic hypotension). If you have low blood pressure or are taking drugs that lower your blood pressure, the risk of low blood pressure is increased.
  • Bleeding problems. Remodulin may increase the risk of bleeding in people who take blood thinners (anticoagulants).

What are the possible side effects of Remodulin?

  • In clinical studies of SC infusion of Remodulin, most people experienced infusion site pain and infusion site reaction (redness, swelling, and rash). These symptoms were sometimes severe and sometimes required treatment with narcotics or discontinuation of Remodulin.
  • IV infusion of Remodulin delivered through an external pump has been associated with the risk of blood stream infections, arm swelling, tingling sensations, bruising, and pain.
  • The most common side effects seen with either SC or IV Remodulin were headache, diarrhea, nausea, rash, jaw pain, widening of the blood vessels (vasodilatation), and swelling from fluid retention (edema). These are not all the possible side effects of Remodulin. Call your doctor for medical advice about side effects.
