| You
can engage in sexual activity within half an hour of taking
the Cialis tablet and up to 36 hours later. It may be possible
for you to engage in sexual activity more than once - for
example, in the evening and again in the morning. The amount
of time Cialis takes to work varies from person to person.
After you have taken Cialis you may wish to attempt sexual
intercourse at different times to decide the best time range
for you and your partner. If you are not sure when to take
Cialis, ask your doctor or health care professional.
Directions
Cialis
tablets are for oral use. Swallow the tablet whole with
water. You may take Cialis with or without food or alcohol.
Side Effects
Tell your doctor or health care professional
as soon as possible if you do not feel well while you are
taking Cialis. Cialis helps most people with erectile dysfunction,
but it may have unwanted side effects in a few people. Most
of the side effects are mild to moderate in nature. Do not
be alarmed by the following list of the most common possible
side effects. You may not experience any of them. Ask your
doctor or health care professional to answer any questions
you may have. Tell your doctor or health care professional
if you notice any of the following and they are troublesome,
severe, or do not go away: headache; indigestion; back pain;
muscle aches; nasal congestion; facial flushing; swelling
of the eyelids; eye pain; conjunctival hyperaemia (red eyes);
dizziness. Allergic reactions to Cialis (including skin
rashes) could occur. In rare instances it is possible that
a prolonged and possibly painful erection may occur after
taking Cialis. If you have such an erection which lasts
continuously for more than 4 hours, you should contact a
doctor immediately. In case of chest pain occurring during
or after sexual activity you should NOT use nitrates but
you should seek immediate medical assistance. Tell your
doctor or pharmacist if you notice anything that is making
you feel unwell.
Warnings
Do not take Cialis if you are currently taking
any nitrates or amyl nitrite. Nitrates are medicines used
in the treatment of angina pectoris ("chest pain"). Cialis
has been shown to increase the effects of these drugs. If
you are taking any form of nitrate or are unsure tell your
doctor. Do not take Cialis if you have had an allergic reaction
in the past to tadalafil or any of the other ingredients
of Cialis. Some of the symptoms of an allergic reaction
to Cialis may include shortness of breath, wheezing or difficulty
breathing; swelling of the face, lips, tongue or other parts
of the body; rash, itching or hives on the skin. Do not
take Cialis after the expiry date printed on the pack or
if the packaging is torn or shows signs of tampering. If
you are not sure whether you should start taking Cialis,
talk to your doctor. Before you start to take Cialis, tell
your doctor if you have allergies to any other medicines,
foods, preservatives or dyes. For those who are lactose
intolerant, be aware that Cialis tablets contain a small
amount of lactose (approximately 200mg for the 10mg tablet
and 250mg for the 20mg tablet). Tell your doctor if you
have or have had any of the following medical conditions:
- you have a heart condition, including angina (chest pain),
arrhythmia (changes in the rhythm or rate of the heart beat),
heart failure or if you have had a heart attack. Sexual
activity carries a possible risk to patients with heart
condition because it puts extra strain on your heart;
- you have had a stroke;
- you have low blood pressure or uncontrolled high blood
pressure;
- you have a serious liver or kidney problem;
- you have sickle cell anaemia (an abnormality of red blood
cells), multiple myeloma (cancer of the bone marrow), leukaemia
(cancer of the blood cells);
- you have any deformation of your penis.
Cialis is not intended for use by women or by children under
the age of 18 years. No special consideration is needed
for the elderly or people with diabetes.
Drug Interactions
Tell your doctor or pharmacist if you are
taking any other medicines, including any that you get without
a prescription from your pharmacy, supermarket or health
food shop. Some medicines and Cialis may interfere with
each other. This is particularly important if you are treated
with: nitrates (used to treat heart conditions); rifampicin
(an antibacterial product used amongst others against tuberculosis);
ketoconazole or itraconazole (used against fungal infections)
erythromycin (an antibacterial product); protease inhibitors
(HIV treatments). You may need different amounts of your
medicines or you may need to use different medicines. You
should not take Cialis together with any other treatments
for erectile dysfunction. Your doctor and pharmacist have
more information on medicines to be careful with or avoid
while taking Cialis.
