Generic for Cialis®
Tadalafil can be used both as a daily treatment or as needed. This treatment plan is focused on as needed tadalafil — how it works and how to effectively and safely use it to enhance erection strength and quality. You will also receive a physical document called a drug monograph or patient drug information in the package with your medication when it arrives from the pharmacy which contains full information about tadalafil — you should read all of the information that comes with your prescription shipment before taking your medication.
Tadalafil belongs to a class of medications called phosphodiesterase 5 inhibitors. These medications boost sexual performance by increasing blood flow to the penis. They work by blocking the enzyme that turns off an erection (phosphodiesterase-5).

How to get the most out of your ED treatment.
1. Timing is key
The effect of tadalafil on sexual performance depends directly on your blood level of tadalafil during sexual activity. Understanding how that blood level changes over time is critical so that you can optimize your performance. Tadalafil first starts to work after 30 minutes, provides maximal support for sexual function 2-6 hours after you take it, and boosts erection quality for up to 36 hours. (see below).
2. Consider a practice run
Trying your first one or two sexual experiences on daily tadalafil in a less pressured, more relaxed environment (i.e. during masturbation) can help you to understand how the medication affects your body and whether or not any treatment adjustments might be helpful before primetime.
3. Give tadalafil a few chances
It can take some time for your body to acclimate to tadalafil, so don’t rush to conclusions about whether or not it works. Things like alcohol consumption, fatigue, anxiety, and arousal can also affect sexual performance on any given day, even when you take medication to enhance sexual function.
4. Get in the mood
Tadalafil works by enhancing and strengthening your body’s response to sexual stimulation and arousal. Some kind of mental or physical trigger is still required to kick off your body’s sexual response.
Tell all your healthcare providers that you take tadalafil. If you need emergency medical care for a heart problem, it will be important for your healthcare provider to know when you last took tadalafil.
It is OK to drink alcohol when taking tadalafil, but not too much. Drinking more than 2-3 glasses of wine, beers, or shots of hard alcohol can increase your chances of headache, dizziness, fast heart rate, and low BP. Alcohol can also inhibit your erection.
The most common side effects with tadalafil are: headache, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose. These side effects usually go away after a few hours. Men who get back pain and muscle aches usually get it 12 to 24 hours after taking tadalafil. Back pain and muscle aches usually go away within 2 days.
1. An erection that won’t go away (priapism)
If you have an erection that lasts more than 4 hours, get medical help right away. If it is not treated right away, priapism can permanently damage your penis.
2. Sudden vision loss
Sudden vision loss in one or both eyes can be a sign of a serious eye problem called non-arteritic anterior ischemic optic neuropathy (NAION). It is uncertain whether PDE5 inhibitors directly cause the vision loss. Stop taking tadalafil and call your healthcare provider right away if you have sudden vision loss in one or both eyes.
3. Sudden hearing decrease or loss
Some people may also have ringing in their ears (tinnitus) or dizziness. If you have these symptoms, stop taking tadalafil and contact a provider right away.
4. Other reported serious side effects
It is not known if tadalafil caused these problems, but other serious medical events that have been reported after tadalafil use include: heart attack, stroke, irregular heartbeats, seizures and death.
For more information, read the written drug information that comes with your medication, ask your healthcare provider, or ask your pharmacist.
