Tadalafil provides great possibilities for patients as this is a medication of new generation. But in spite of the fact, that possibilities are huge, no manufacturer can guarantee 100% safety. This matter should be a question of particular concern because if medication does not help then it should be changed to a different medication.
First of all, you should not take the medication if you are hypersensitive to it. It is always so that the person can be allergic to some component of medication therefore it is advisable for him not to take the medication. Tadalafil may not be allowed for you if you had some problems with heart. It may be so that doctor recommended sexual abstinence for the person as cardiac tension can be very dangerous for him.

When some of the side effects bother you then you should apply to the doctor to decide if it is worth taking Tadalafil treatment further.
There is a range of conditions that are contraindicated for Tadalafil treatment. Read a list of contraindications to find out it is referred to you in this or that way.

When combined with alpha-blockers or antihypertensive drugs Tadalafil can create dangerous combination. Your doctor should evaluate the possibility of such interaction and determine if there is some risk here.
