Some medicines may interfere with CIALIS and affect how it works. Please read this leaflet carefully before you start using Cialis. Some may require a prescription from an independent physician, some may be able to write you a prescription after some screening questions, and others may not require a prescription at all. Last, make sure you understand the purchasing policies of the online pharmacy you choose. Believe it or not, shopping from an online pharmacy isn’t very different from shopping from any other online store.
In rare instances, men taking prescription ED tablets, including Cialis, reported a sudden decrease or loss of vision or hearing (sometimes with ringing in the ears and dizziness). It's not possible to determine if these events are related directly to the ED tablets or to other factors. If you have a sudden decrease or loss of vision or hearing, stop taking any ED tablet, including Cialis and call a healthcare provider right away.
Decreased or sudden hearing loss has been noted in some patients taking tadalafil. Although it is not known if the event is directly related to tadalafil, if you experience decreased or sudden hearing loss, stop taking CIALIS and contact your doctor immediately. If you experience sudden decrease or loss of vision or your vision is distorted, dimmed while you are taking CIALIS, stop taking CIALIS and contact your doctor immediately. It is important to note that CIALIS does not work if there is no sexual stimulation. You and your partner will need to engage in foreplay, just as you would if you were not taking a medicine for erectile dysfunction.
Cialis is a substrate of and predominantly metabolized by CYP3A4. Studies have shown that drugs that inhibit CYP3A4 can increase tadalafil exposure. The following adverse reactions have been identified during post approval use of Cialis. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These events have been chosen for inclusion either due to their seriousness, reporting frequency, lack of clear alternative causation, or a combination of these factors.
This gives approximately 16 and 10 fold exposure multiples, respectively, of the human AUC for the MRHD of 20 mg. There were no treatment-related testicular findings in rats or mice treated with doses up to 400 mg/kg/day for 2years. In patients with mild or moderate hepatic impairment, the dose of CIALIS should not exceed 10 mg. Coadministration of tadalafil (40 mg once per day) for 10 days did not have a significant effect on the steady-state pharmacokinetics of digoxin (0.25 mg/day) in healthy subjects. CIALIS is not expected to cause clinically significant inhibition or induction of the clearance of drugs metabolized by cytochrome P450 (CYP) isoforms. Studies have shown that tadalafil doe snot inhibit or induce P450 isoforms CYP1A2, CYP3A4, CYP2C9, CYP2C19, CYP2D6, and CYP2E1.
Viagra and Cialis have different active ingredients although they’re both PDE-5 inhibitors. This means they relax the smooth muscles in the blood vessels supplying the penis. In Viagra the PDE-5 inhibitor is sildenafil, while in Cialis it is tadalafil. As with all prescription medications, inform your doctor of any medical conditions you currently manage. Tell them about any and all medications, prescription drugs, and supplements you are taking before starting treatment with Cialis. Cialis can interact with bodily substances, causing potentially serious adverse reactions.
If you experience a sudden loss of vision while you are taking tadalafil, call your doctor immediately or get emergency medical treatment. Cialis (tadalafil) relaxes muscles of the blood vessels and increases blood flow to particular areas of the body. Cialis is used to treat erectile dysfunction ED and symptoms of benign prostatic hypertrophy (enlarged prostate).
They are both PDE5 inhibitors
