When reading about medications, you will often see or read about their side effects.  The truth is, many of the side effects that PDE5 inhibitor drugs have are quite worrying.  PDE5 inhibitor drugs are the medications they use for the treatment of erectile dysfunction.  Drugs like Viagra (sildenafil), Levitra (vardenafil), and of course Cialis (tadalafil) are all PDE5 inhibitor drugs.  The truth about the side effects that you see written are only potential side effects and many of them do not occur with every individual that takes them.  They may occur with a few individuals, but among the many hundreds of thousands or millions of men taking them, not even 10 percent of them will experience the more serious side effects that these drugs have.  This is the every reason why you should consult your doctor first before considering taking any of these drugs.

Tadalafil these days is one of the drugs that stand out the most among the three big names in erectile dysfunction medications.  This is because tadalafil has 36 hours of effective duration – the longest of any ED drug out in the market today.  This 36 hours of effective duration is actually quite significant when you compare it to the measly 4 hours effective duration that Viagra can give.  With 36 hours, couples can go for additional rounds of lovemaking whenever they feel like it.  With Viagra, after the first four hours of effective duration have passed, the couple needs to wait 20 more hours before the guy can take another dose.  Not with tadalafil though as the effect is still there even after 24 hours.  Such long effective duration can even mean better savings for the couple.

Again, when it comes to safety of taking this drug, yes, the drug is safe to use, the same way as Viagra and Levitra are safe to use.  All these drugs are safe to use provided you follow certain measures such as not taking them along with drugs that will react or contraindicate with them.  Among the drugs that you should not use with these medications are nitrate drugs like isosorbide mononitrate or isosorbide dinitrate because these drugs when taking along with PDE5 inhibitor drugs can cause a dangerously low blood pressure that is fatal if left untreated.  Also, it is important that you are not allergic to the drug when taking it.  If you are unsure but have taken tadalafil, it is important to watch for signs of any allergic reactions like itching, swelling, or hives.

Tadalafil comes in different dosages.  It is important that you strictly follow the dosage given to you by your doctor.  If you feel that the dose given to you is too strong or is perhaps too weak to your measure, make sure that you do not make any self-adjustment on your dosage as this is not highly advised.  Try to contact your doctor and tell him your concerns and allow him to make the necessary adjustments for you.  If your doctor however is uncertain of the adjustment, a reassessment may be necessary.
