Contraindications for Cialis (Tadalafil)

tablets and pills

What is the dose for Cialis?

For most individuals, the recommended starting dose of Cialis is 10 mg per day before sexual activity. Depending on the adequacy of response or side effects, the dose may be increased to 20 mg or decreased to 5 mg per day.

The effect of Cialis can last up to 36 hours. People taking medications should not exceed a total dose of 10 mg in 72 hours.

Cialis should not be taken more than once daily.

It can be taken with or without food since the food does not affect its absorption from the intestine.

The dose of tadalafil may require adjustment for patients with reduced renal or hepatic function.

What drugs or supplements interact with Cialis?

The breakdown and elimination of tadalafil from the body can be decreased by erythromycin, ketoconazole (Nizoral), itraconazole (Sporanox), indinavir (Crixivan) and ritonavir (Norvir).

Therefore, these medications can increase tadalafil levels in the blood. If these drugs are used at the same time as Cialis, the dose of Cialis should be reduced to 10 mg every 72 hours when used as needed or 2.5 mg when used daily to avoid side effects of high levels of tadalafil.

Rifampin, carbamazepine (Tegretol, Tegretol XR, Equerto, Carbatrol), phenytoin (Dilantin, Dilantin-125) and phenobarbital can lower blood levels of tadalafil, possibly reducing the effect of Cialis.

Cialis exaggerates increases in heart rate and a decrease in blood pressure caused by nitrates, eg nitroglycerin, isosorbide dinitrate (Isordil), isosorbide mononitrate (Imdur, Ismo, Monoket), nitroglycerin (Nitro-Dur, Transderm -Nitro) for the treatment of heart pain (angina).

In patients taking nitrates for angina, tadalafil could cause heart pain or even a heart attack by exaggerating increased heart rate and lowering blood pressure. Therefore, Cialis should not be used with nitrates.

Cialis also exaggerates the blood pressure lowering effects of some alpha-blocking drugs, eg terazosin (Hytrin) which are mainly used to treat high blood pressure or enlarged prostate (BPH).

People taking these alpha-blockers should be on a stable dose of the alpha-blocker before tadalafil is started. In such situations, Cialis should start with the lowest dose. If the patient is already taking Cialis, the alpha-blocker should be started at the lowest dose. The combination of tadalafil and alpha-blockers is not recommended for the treatment of BPH.

Cialis and alcohol lower blood pressure. Therefore, the combination of Cialis with alcohol can cause excessive drops in blood pressure and cause dizziness, headaches and increased heart rate.

PDE5 inhibitors may affect platelet function and therefore prolong bleeding. Cialis should be used with caution in patients with bleeding disorders or active ulcers. Cialis should not be combined with Adcirca (another form of tadalafil) or other PDE5 inhibitors, eg vardenafil (Levitra) or sildenafil (Viagra, Revatio).

I like Cialis the most comparing to other drugs for erectile dysfunction. Before that, tried Viagra, I had a slight reddening on my face after that, most likely due to the slightly increased blood pressure. After Levitra I also had reddening of the face and slight dizziness. But maybe it just the wine 😉 In general, the effect of the Cialis is much softer with an increased sex duration, and the erection from it is stronger and lasts longer! I like that to have sex not for a few hours, but for the whole day, the duration is excellent!

Service – A+ (quickly and without problems, even received a small consultation) Price – A (cheaper than expected) Quality – A+ I tried only half a tablet of Cialis (analogue of Viagra). The effect is very mild, that is, I did not feel any side effects at all, no fever, no sudden influx of heat on the face, no headache, as was the case with Levitra. The erection lasted almost a day and almost a day there was a heightened excitability. That is not an erection lasted a day, namely, the willingness to have sex. Of course, I could do all this time and do the usual things. I’m 43 years old, I have a healthy lifestyle, but I did not experience such feelings even in my youth.
