Cialis should not be taken if you are taking certain other medications due to serious and potentially life threatening interactions. It is really important that you give us a full list of ALL the medicines you are taking every time you use our service.
Do not use Cialis if you are taking Nicorandil or any Nitrates.
Nitrates are found in some heart medications such as a GTN spray or tablets that you put under your tongue and isosorbide mononitrate/dinitrate used for angina, as well as in certain recreational drugs such as “poppers”, “room odorizers” and “aromas”. They can also be found in other medications so it's very important that you list all the medicines and recreational drugs you have or are taking when asked. This is because when combined with ED medications, they can cause a serious and life threatening drop in blood pressure, which can be fatal.
If you are taking alpha-blockers (such as alfuzosin, doxazosin, tamsulosin or terazosin), you must not use Cialis as it can cause a dangerous drop in your blood pressure.
This is not a full list of all the medication interactions - Cialis can interact dangerously with other medicines. Please list ALL the medicines you are taking when asked. If you subsequently start taking a new medication, before taking your Cialis please always check with our doctors first by sending a message via your Patient Record, to ensure the Cialis is still safe to take.
