Drug Uses
Cialis is a prescription medicine taken by mouth
for the treatment of erectile dysfunction (ED) in men.
How Taken
Take Cialis exactly as your doctor prescribes.
Cialis comes in different doses (5 mg, 10 mg, and 20 mg). For most men, the
recommended starting Cialis dose is 10 mg. Cialis should be taken no more than
once a day. Your doctor will prescribe the dose that is right for you.
Warnings/Precautions
Cialis can cause your blood pressure to
drop suddenly to an unsafe level if it is taken with certain other medicines
such as nitrates and alpha-blockers, and recreational drugs that contain
nitrates called "poppers". A sudden drop in your blood pressure could cause you
to become dizzy, faint, or have a heart attack or stroke. Until you are certain
how you are affected by Cialis, use caution when driving or operating heavy
machinery. Cialis contains some lactose and should not be taken by patients who
are lactose intolerant. Also, during treatment you should avoid grapefruit
juice. Taking Cialis with grapefruit juice can increase your chances of
experiencing undesirable side effects. If you are taking medications with
nitrates or nitric oxide, have uncontrolled blood pressure (high or low), or if
you have a history of stroke or heart attack DO NOT take Cialis.
Missed Dose
Take the missed dose as soon as you
remember it. However, if it is almost time for the next dose, skip the missed
dose and continue your regular dosing schedule. Do not take a double dose to
make up for a missed one.
Possible Side Effects
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. Patients 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 by themselves within 48 hours. Call
your doctor if you get a side effect that bothers you or one that will not go
away.
Storage
Store Cialis at room temperature between
59 and 86 F (15 and 30 C).
Overdose
In cases of overdose, standard supportive
measures should be adopted as required. Hemodialysis contributes negligibly to
Cialis elimination.
More Information
Do not change your dose of Cialis without
talking to your doctor. Your doctor may lower your dose or raise your dose,
depending on how your body reacts to Cialis. Do not drink alcohol to excess when
taking Cialis (for example, 5 glasses of wine or 5 shots of whiskey). When taken
in excess, alcohol can increase your chances of getting a headache or getting
dizzy, increasing your heart rate, or lowering your blood pressure.

inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase

It is a
crystalline solid that is practically insoluble in water and very slightly
soluble in ethanol.

administration. Each tablet contains 5, 10, or 20 mg of tadalafil and the
following inactive ingredients: croscarmellose sodium, hydroxypropyl cellulose,
