1. What CIALIS is and what it is used for
CIALIS is a treatment for adult men with erectile dysfunction. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity. CIALIS has been shown to significantly improve the ability of obtaining a hard erect penis suitable for sexual activity.
CIALIS contains the active substance tadalafil which belongs to a group of medicines called phosphodiesterase type 5 inhibitors. Following sexual stimulation CIALIS works by helping the blood vessels in your penis to relax, allowing the flow of blood into your penis. The result of this is improved erectile function. CIALIS will not help you if you do not have erectile dysfunction.
It is important to note that CIALIS does not work if there is no sexual stimulation. You and your partner will need to engage in foreplay, just as you would if you were not taking a medicine for erectile dysfunction.
2. What you need to know before you take CIALIS
Do not take CIALIS if you:
- are allergic to tadalafil or any of the other ingredients of this medicine (listed in section 6).
- are taking any form of organic nitrate or nitric oxide donors such as amyl nitrite. This is a group of medicines (“nitrates”) used in the treatment of angina pectoris (“chest pain”). CIALIS has been shown to increase the effects of these medicines. If you are taking any form of nitrate or are unsure tell your doctor.
- have serious heart disease or recently had a heart attack within the last 90 days.
- recently had a stroke within the last 6 months.
- have low blood pressure or uncontrolled high blood pressure.
- ever had loss of vision because of non-arteritic anterior ischemic optic neuropathy (NAION), a condition described as “stroke of the eye”.
- are taking riociguat. This drug is used to treat pulmonary arterial hypertension (i.e., high blood pressure in the lungs) and chronic thromboembolic pulmonary hypertension (i.e., high blood pressure in the lungs secondary to blood clots). PDE5 inhibitors, such as CIALIS, have been shown to increase the hypotensive effects of this medicine. If you are taking riociguat or are unsure tell your doctor.
Warnings and precautions
Talk to your doctor before taking CIALIS.
Be aware that sexual activity carries a possible risk to patients with heart disease because it puts an extra strain on your heart. If you have a heart problem you should tell your doctor.
Before taking the tablets, tell your doctor if you have:
- sickle cell anaemia (an abnormality of red blood cells).
- multiple myeloma (cancer of the bone marrow).
- leukaemia (cancer of the blood cells).
- any deformation of your penis.
- a serious liver problem.
- a severe kidney problem.
It is not known if CIALIS is effective in patients who have had:
- pelvic surgery.
- removal of all or part of the prostate gland in which nerves of the prostate are cut (radical non-nerve-sparing prostatectomy).
If you experience sudden decrease or loss of vision, stop taking CIALIS and contact your doctor immediately.
Decreased or sudden hearing loss has been noted in some patients taking tadalafil. Although it is not known if the event is directly related to tadalafil, if you experience decreased or sudden hearing loss, stop taking CIALIS and contact your doctor immediately.
CIALIS is not intended for use by women.
Children and adolescents
CIALIS is not intended for use by children and adolescents under the age of 18.
Other medicines and CIALIS
Tell your doctor if you are taking, have recently taken or might take any other medicines
Do not take CIALIS if you are already taking nitrates.
Some medicines may be affected by CIALIS or they may affect how well CIALIS will work. Tell your doctor or pharmacist if you are already taking:
- an alpha blocker (used to treat high blood pressure or urinary symptoms associated with benign prostatic hyperplasia).
- other medicines to treat high blood pressure.
- riociguat.
- a 5- alpha reductase inhibitor (used to treat benign prostatic hyperplasia).
- medicines such as ketoconazole tablets (to treat fungal infections) and protease inhibitors for treatment of AIDS or HIV infection.
- phenobarbital, phenytoin and carbamazepine (anticonvulsant medicines).
- rifampicin, erythromycin , clarithromycin or itraconazole.
- other treatments for erectile dysfunction.
CIALIS with drink and alcohol
Information on the effect of alcohol is in section 3. Grapefruit juice may affect how well CIALIS will work and should be taken with caution. Talk to your doctor for further information.
Fertility
When dogs were treated there was reduced sperm development in the testes. A reduction in sperm was seen in some men. These effects are unlikely to lead to a lack of fertility.
Driving and using machines
Some men taking CIALIS in clinical studies have reported dizziness. Check carefully how you react to the tablets before driving or using machines.
CIALIS contains lactose
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
CIALIS contains sodium
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.
3. How to take CIALIS
Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
CIALIS tablets are for oral use in men only. Swallow the tablet whole with some water. The tablets can be taken with or without food.
The recommended starting dose is one 10 mg tablet before sexual activity. However, you have been given the dose of one 20mg tablet as your doctor has decided that the recommended dose of 10mg is too weak.
You may take a CIALIS tablet at least 30 minutes before sexual activity.
CIALIS may still be effective up to 36 hours after taking the tablet.
Do not take CIALIS more than once a day. CIALIS 10 mg and 20 mg is intended for use prior to anticipated sexual activity and is not recommended for continuous daily use.
It is important to note that CIALIS does not work if there is no sexual stimulation. You and your partner will need to engage in foreplay, just as you would if you were not taking a medicine for erectile dysfunction.
Drinking alcohol may affect your ability to get an erection and may temporarily lower your blood pressure. If you have taken or are planning to take CIALIS, avoid excessive drinking (blood alcohol level of 0.08 % or greater), since this may increase the risk of dizziness when standing up.
If you take more CIALIS than you should
Contact your doctor. You may experience side effects described in section 4.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

【用法用量】口服，用于成年男性：本品的推荐剂量为10mg，在进行性生活之前服用,不受进食的影响，如果服用10mg效果不显著，可以服用20mg。可至少在性生活前30分钟服用，最大服药频率为每日一次，最好不要连续每日服用他达拉非，因为尚未确定长期服用的安全性。同时，因为他达拉非的作用经常持续超过一天，用于老年男性:老年人无须调整剂量。用于肾功能不全的男性：对于轻至中度肾功能不全的患者无须调整剂量。对于重度肾功能不全的患者，最大的推荐剂量为10mg。
【不良反应】眼睑肿胀或者描述为眼痛和结膜充血是非常少见的副反应。报告显示由他达拉非所引起的副反应是短暂的、轻微的或者是中度的。这些副反应是数据只对年龄在75以下的病人适用。
【注意事项】在考虑给予药物治疗之前,应当先询问病史和对患者进行体检。以诊断是否患有男性勃起功能障碍和确定可能的未知病因，因为心血管病的发病几率与性行为有一定程度的相关，所以医生在对男性勃起功能障碍患者进行治疗以前，包括他达拉非，应当考虑患者的心血管健康状况。由于他达拉非具有使血管扩张的特性,所以会导致血压轻度的、短暂的降低，这种特性可能增强硝酸盐的降压效果。严重的心血管疾病，包括心肌梗塞、不稳定型心绞痛、室性心律失常、休克、短暂性缺血性发作等曾经在他达拉非的临床试验中观察到。
【禁忌】临床研究表明他达拉非可以增强硝酸盐类药物的降压作用。这被认为硝酸盐类药物和他达拉非共同作用于一氧化氮/cGMP通路的结果。因此，正在服用任何形式的硝酸盐类药物的患者禁止服用本品。性生活会给心脏病患者带来潜在的心脏风险。因此，勃起功能障碍的治疗药物，包括他达拉非在内，不应用于建议不宜进行性生活的心脏病患者。对已患有心脏病的患者，医生应考虑性生活潜在的心脏风险。
