Cialis works by relaxing muscles while increasing blood flow especially in specific areas of your body. The drug, Cialis is mainly used for purposes of treating ED (Erectile Dysfunction) and other similar symptoms that affect men. Furthermore, it can additionally be used to treat symptoms associated with an enlarged prostate. Although these are just some of the few uses of the drug, there are other numerous uses that have made Cialis very popular all over the world.
If for any reason you have previously noticed that you are allergic to the drug Tadalafil, then you are strongly advised not to use Cialis. Also, users are warned against using the drug while on nitrate drug medication used to treat heart and chest conditions. The same applies to drugs that contain ingredients that include isosorbide, nitroglycerin, isosorbide mononitrate and isosorbide dinitrate. Nitrates are additionally available in most recreational drugs like nitrite and amyl nitrate. Consequently, combining Cialis with other nitrate medication could easily cause serious drop in your blood pressure. For this reason, mixing these drugs is not advisable.
Furthermore, if you notice that your erection has lasted a period of more than 4 hours and it is causing you unbearable pain, you need to consult a doctor or seek medical attention immediately.
How Cialis Should Be Taken
CIalis should ideally be taken once each day. Therefore, follow all the directions as indicated on the prescription label. Taking the medicine in smaller or larger amounts for a period longer than is recommended is strongly discouraged. Even so, the wonder drug can be taken together with food. However, you can also take it without food.
If you are taking the drug due to erectile dysfunction, then you are advised to take your dose prior to engaging in sexual activity. Despite this, the drug should not be taken more than once each day. This wonder drug will make it easier for you to get an erection especially when you are sexual stimulated. Remember, an erection does not necessarily occur simply if you take the pill. This is the main reason why users are encouraged to follow instructions provided by doctors. If you are engaging in sexual activity and you suddenly notice that you are nauseated, dizzy, have pain or tingling within your neck, chest, jaw, or arms, it is advisable that you stop right away and call a doctor. Any of these symptoms could be an indication of severe side effects.
Grapefruit or grapefruit juice may react badly with Cialis thus leading to bad side effects. Therefore, avoid the fruit if you are on the medication. Doctors also advise users against drinking alcohol while taking the drug as this could worsen some side effects.
Clinical tests performed on different people prove that Cialis is effective in more than 81% of men. However, if you note at any point that the wonder drug does not facilitate an erection, or your erection does not stay for as long as you would wish to finish up on sexual activity, then you should consult your doctor.
