CIALIS® (tadalafil): Official Site

Now That You've Made Up Your Mind

Deciding to talk with your doctor about ED (erectile dysfunction) is not easy. Once you make up your mind to do it, these steps can help.

Step 1:	Make an appointment. You can tell the receptionist the appointment is for "a men's health visit." Or, if you're not comfortable doing it, you can ask your partner to make the appointment for you.
Step 2:	Take the "Could It Be ED?" Quiz. Print the completed quiz and bring it to the doctor visit with you. It can help your doctor determine if you have ED and how ED may be affecting you.
Step 3:	Write down all the medicines you currently take and bring the list to your doctor visit. The list should include all: Prescription medicines Over-the-counter medicines Herbal and/or vitamin supplements

The doctor needs this information for two important reasons. A medicine you take could be causing ED as a side effect. CIALIS and other medicines may affect each other. Always check with your healthcare provider before starting or stopping any medicines. Especially tell your healthcare provider if you take any of the following*:

Medicines called nitrates
Medicines called alpha-blockers. These include Hytrin^® (terazosin HCl), Flomax^® (tamsulosin HCl), Cardura^® (doxazosin mesylate), Minipress^® (prazosin HCl), or Uroxatral^® (alfuzosin HCl). Alpha-blockers are sometimes prescribed for prostate problems or high blood pressure. If CIALIS is taken with certain alpha-blockers, your blood pressure could suddenly drop. You could get dizzy or faint
Other medicines to treat high blood pressure (hypertension)
Medicines called HIV protease inhibitors, such as ritonavir (Norvir^®, Kaletra^®)
Ketoconazole (Nizoral^®)
Itraconazole (Sporanox^®)
Erythromycin
Other medicines or treatments for ED
CIALIS is also marketed as ADCIRCA^™ (tadalafil) for the treatment of pulmonary arterial hypertension. Do not take both CIALIS and ADCIRCA. Do not take REVATIO^® (sildenafil) with CIALIS

Important Safety Information for CIALIS^® (tadalafil)

Who Should Not Take CIALIS?

Do not take CIALIS if you:

take medicines called "nitrates" which are often prescribed for chest pain as the combination may cause an unsafe drop in blood pressure
use recreational drugs called "poppers" like amyl nitrite and butyl nitrite
are allergic to CIALIS or ADCIRCA ^™ (tadalafil), or any of its ingredients

What Should I Tell My Healthcare Provider Before Taking CIALIS?

CIALIS is not right for everyone. Only your healthcare provider and you can decide if CIALIS is right for you. Before taking CIALIS, tell your doctor about all your medical problems, particularly if you have or ever had:

an allergy to CIALIS or ADCIRCA or any of its ingredients
heart problems such as angina, heart failure, irregular heartbeats, or have had a heart attack
high or low blood pressure
stroke
liver or kidney problems
severe vision loss, including a condition called NAION
retinitis pigmentosa, a rare genetic (runs in families) eye disease
a deformed penis shape or Peyronie's disease
an erection that lasted more than 4 hours
blood cell problems such as sickle cell anemia, multiple myeloma, or leukemia

Ask your healthcare provider if it is safe for you to have sexual activity. You should not take CIALIS if your healthcare provider has told you not to have sexual activity because of your health problems. Stop sexual activity and get medical help right away if you get symptoms such as chest pain, dizziness, or nausea during sex.

Can Other Medicines Affect CIALIS?

After taking a single tablet, some of the active ingredient of CIALIS remains in your body for more than 2 days. Tell your healthcare provider about all the medicines you take especially if you take:

medicines called “nitrates” which are often prescribed for chest pain
alpha blockers often prescribed for prostate problems
blood pressure medications
medicines for HIV or antifungal medications
erythromycin
other medicines or treatments for ED
CIALIS is also marketed as ADCIRCA for the treatment of pulmonary arterial hypertension. Do not take both CIALIS and ADCIRCA. Do not take sildenafil citrate (Revatio^™) with CIALIS.

What Should I Avoid While Taking CIALIS?

Do not use other ED medicines or ED treatments while taking CIALIS.
Do not drink too much alcohol when taking CIALIS (for example, 5 glasses of wine or 5 shots of whiskey). Drinking too much alcohol can increase your chances of getting a headache or getting dizzy, increasing your heart rate, or lowering your blood pressure.

What Are The Possible Side Effects Of CIALIS?

The most common side effects with CIALIS are: headache, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose. These side effects usually go away after a few hours. Men who get back pain and muscle aches usually get it 12 to 24 hours after taking CIALIS. Back pain and muscle aches usually go away within 2 days. Call your healthcare provider if you get any side effect that bothers you or one that does not go away.

Uncommon side effects include:

An erection that won't go away: As with any ED tablet, in the rare event of an erection lasting more than 4 hours, seek immediate medical help to avoid long-term injury.

In rare instances, men taking prescription ED tablets (including CIALIS) reported a sudden decrease or loss of vision or hearing (sometimes with ringing in the ears and dizziness). It's not possible to determine if these events are related directly to the ED tablets or to other factors. If you have a sudden decrease or loss of vision or hearing, stop taking any ED tablet, including CIALIS and call your doctor right away.

CIALIS does not:

cure ED
increase a man's sexual desire
protect a man or his partner from sexually transmitted diseases, including HIV
serve as a male form of birth control
