Adcirca (Generic Tadalafil)
Actual product appearance may differ slightly.
Why is this medication prescribed?
Tadalafil (Cialis) is used to treat erectile dysfunction (ED, impotence; inability to achieve or maintain an erection) and the signs and symptoms of benign prostatic hyperplasia (BPH; an enlarged prostate), which include painful urination, frequent and urgent urination, and difficulty urinating (hesitation, dribbling, weak stream, and incomplete bladder emptying) in adult men. Using tadalafil (Adcirca), persons with pulmonary arterial hypertension can exercise more easily (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). A group of drugs known as phosphodiesterase (PDE) inhibitors includes tadalafil. By boosting blood flow to the penis during sexual stimulation, it helps treat erectile dysfunction. An erection may result from this increased blood flow. Tadalafil cures PAH by loosening the blood arteries in the lungs, facilitating easier blood flow.
You should be aware that tadalafil does not treat erectile dysfunction or raise sexual desire if you are using it to treat it. Tadalafil does not stop pregnancy or the transmission of sexually transmitted illnesses like the HIV virus (HIV).
How should this medicine be used?
Tadalafil is available as an oral tablet. Taking it with or without food is acceptable.
If you are taking tadalafil to treat erectile dysfunction, abide by this paragraph’s instructions and those given by your doctor. Tadalafil can be taken daily or as needed, depending on the situation. Which dose regimen is best for you should be discussed with your doctor. When necessary, tadalafil is occasionally taken, typically at least 30 minutes before sexual activity, and not more frequently than once per 24 hours. The ideal time for you to take tadalafil prior to sexual activity will be determined by your doctor. In certain cases, tadalafil is taken once daily, every day, regardless of when a person engages in sexual activity. If you regularly take tadalafil, take it at roughly the same time each day. Your doctor could advise you to take tadalafil less frequently or might give you a lower dose to use once daily if you have certain medical conditions or are taking certain drugs. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Tadalafil should be used as prescribed. Never take it in larger or less amounts or more frequently than directed by your doctor.
Pay attention to your doctor’s instructions and the recommendations in this paragraph if you’re using tadalafil to treat PAH or BPH. Tadalafil should be taken once day. Do not divide the tablets to be taken in separate doses; take the entire daily dose at once each day. Take tadalafil every day at roughly the same time. Your doctor might advise you to stop taking any other medications at least one day prior to beginning tadalafil therapy if you are already receiving medicine to treat BPH. Ask your doctor or pharmacist to explain any instructions you do not understand, and carefully follow them.
If you are taking tadalafil to treat erectile dysfunction, your doctor will likely start you on an average dose and then adjust it based on how you react to the drug. If tadalafil is not working as well as it should or if you experience any negative effects, let your doctor know.
If you are taking tadalafil to treat PAH, you should be aware that it only manages the condition. Tadalafil should still be used even if you feel fine. Without first seeing your doctor, never stop taking tadalafil.

What special precautions should I follow?
Before taking tadalafil,
- If you have an allergy to tadalafil, any other drugs, or any of the substances in tadalafil tablets, tell your doctor and pharmacist right away. Request a list of the components from your pharmacist.
- Inform your doctor if you take riociguat (Adempas) or nitrates such isosorbide dinitrate (Isordil), isosorbide mononitrate (Monoket), or nitroglycerin currently or have recently (Minitran, Nitro-Dur, Nitromist, Nitrostat, others). Pills, sublingual (under the tongue) tablets, sprays, patches, pastes, and ointments are all forms of nitrates. If you are unsure whether any of your drugs include nitrates, consult your doctor. If you are taking nitrates, your doctor generally won’t advise you to use tadalafil.
- If you are taking nitrate-containing street drugs (often known as “poppers”) like amyl nitrate, butyl nitrate, or nitrite while taking tadalafil, let your doctor know. Tadalafil shouldn’t be taken if you are using nitrate-containing street drugs, your doctor will likely advise you.
- You should be aware that the brand names Adcirca and Cialis are used to sell tadalafil. One of these products should be used to treat you at a time.
- Inform your doctor and pharmacist about any additional prescription and over-the-counter drugs, vitamins, and dietary supplements you are currently taking or intend to take. Incorporate any of the following: amiodarone (Cordarone, Pacerone); alpha blockers such as alfuzosin (Uroxatral), doxazosin (Cardura), dutasteride (Avodart, in Jalyn), prazosin (Minipress), silodosin (Rapaflo), tamsulosin (Flomax, in Jalyn), and terazosin; a number of antifungal medications, including fluconazole (Diflucan), griseofulvin (Grifulvin, Gris-PEG), itraconazole (Onmel, Sporanox), ketoconazole (Extina, Ketozole, Nizoral, Xolegel), and voriconazole (Vfend); as well as aprepitant (Emend), bosentan (Tracleer), carbamazepin; medications for high blood pressure; nefazodone; nevirapine (Viramune); other drugs or treatments for erectile dysfunction; diltiazem (Cardizem, Cartia, Tiazac, etc.); efavirenz (Sustiva, in Atripla); erythromycin (E.E.S., E-Mycin, Erythrocin); HIV protease inhibitors such as indinavir; others include phenobarbital, phenytoin (Dilantin, Phenytek), rifabutin (Mycobutin), rifampin (Rifadin, Rimactane, in Rifamate, in Rifater), sertraline (Zoloft), telithromycin (Ketek), and verapamil (Calan, Covera,Verelan, in Tarka). The dosage of your drugs may need to be adjusted, and your health may need to be closely watched for any negative effects.
- Please let your doctor know if you are taking any herbal supplements, especially St. John’s wort.
- Inform your doctor if you smoke, if you’ve ever experienced an erection that lasted longer than four hours, or if you recently experienced diarrhoea, vomiting, a lack of fluid intake, or excessive perspiration that could have resulted in dehydration (loss of a significant amount of body fluids). Tell your doctor if you have or have ever had any of the following conditions: diabetes, high cholesterol, high or low blood pressure, irregular heartbeat, heart attack, heart failure, angina (chest pain), stroke, stomach ulcers, bleeding disorder; pulmonary veno-occlusive disease (PVOD; blockage of veins in the lungs); problems with the blood circulation; issues with the blood cells, such as sickle cell anaemia (a disease of the red blood cells); multiple myeloma; leukaemia; or heart, kidney, or liver disorders. Tell your doctor if you have ever experienced sudden, severe vision loss, especially if you were informed that the loss of vision was brought on by a blockage of blood flow to the nerves that aid in vision, or if you or any family members have retinitis pigmentosa, an inherited eye condition that causes loss of vision.
- If you are a woman using tadalafil to treat PAH, be sure to let your doctor know if you are currently breastfeeding or want to get pregnant. Call your physician if you conceive while taking tadalafil.
- Inform your doctor or dentist that you are taking tadalafil if you are having surgery, including dental surgery.
- During your tadalafil therapy, discuss with your doctor if you should consume alcohol. When using tadalafil, you are more likely to suffer certain adverse effects like dizziness, headache, a rapid heartbeat, and low blood pressure if you consume a lot of alcohol (more than five glasses of wine or five shots of whisky).
- If you’re using tadalafil to treat erectile dysfunction, let your doctor know if you’ve ever received a recommendation from a medical expert to refrain from sexual activity or if you’ve ever felt any kind of pain in your chest while having sex. In particular, if you have heart problems, sexual activity may put a burden on your heart. Avoid sexual activity until your doctor advises you not to if you have chest pain, lightheadedness, or nausea while having sex. Call your doctor right away or seek emergency medical attention.
- Inform all of your medical professionals that you are taking tadalafil. The medical professionals who treat you will need to know when you last took tadalafil if you ever require emergency medical care for a heart condition.
