About Cialis® (Tadalafil)

Cialis® is one of the most popular erectile dysfunction treatments and can last for up to 36 hours when taking a stronger dose.


It’s taken orally as a tablet with a glass of water. If you’re using the Daily dose, it’s once a day at the same time. When using the 36 hour dose, it’s taken 30 mins to 1 hour before sex. You only need to take it when you plan on being sexually active.


Cialis® (Tadalafil) can be taken on demand, flexibly when required, but you must never take more than one dose per day.

FAQs

Tadalafil is the active ingredient in Cialis® and is available in a generic, unbranded tablet. Tadalafil and Cialis® are medically equivalent but tadalafil is available at a much lower cost.
Generic medicines contain the same active ingredient and are equally effective and medically equivalent to the branded products, but are available at a lower price. Generic manufacturers have to demonstrate that they are medically identical to the branded product — in other words, they offer the same quality, strength, stability and effectiveness.
Cialis® comes in two doses, either 10 mg or 20 mg. It’s recommended that you start with the 10 mg tablet and continue if this is effective, as lower doses have less chance of side effects. If you find it’s not having the desired effect on your erection after several separate attempts, you can try increasing the dose to 20 mg. If you’re still not satisfied with the results, talk to your doctor about other medication solutions for you.
Cialis Daily® is available in two strengths of 2.5 mg and 5 mg. Usually men begin with the 5 mg dose and adjust as needed. If you find that you’re experiencing side effects or the 5 mg seems to be too strong for you, you can try decreasing the dose to 2.5 mg.
Like all medications, ED treatments can cause some side effects. The most common ones are: headaches, muscle aches, back pain, flushing, low blood pressure, abnormal vision and indigestion. Please speak with your GP or pharmacist if you experience any of these side effects for a prolonged period of time.
Cialis® has fewer side effects than other medications used to treat erectile dysfunction. In fact, many men who experience nasal congestion, stomach pain, nausea and diarrhoea with other drugs find that they can take tadalafil without side effects.
Always read the patient information leaflet that’s provided inside the box of your medication before starting treatment.
