Cialis Recommended Dose, Side Effects, Interactions
The Cialis recommended dose for occasional use is 20 mg.
When using a pharmaceutical such as Cialis, dosage is an extremely important factor. The erectile dysfunction medication is available in a range of dosage options. Which one should you use? What doses does Cialis come in? We take a look at how to use this medicine as well as a few warning signs that show it either doesn’t agree with you, or you are using too much.
What Is Cialis Really?
Cialis is PDE5 inhibitor that blocks an enzyme that prevents the mechanism for obtaining an erection from working as it should. Its real active ingredient is Tadalafil, and generic versions (having the same ingredients) are available under a range of names other than Cialis.
Although there is some evidence of Viagra working for women, there is no such evidence regarding Cialis, thus it is primarily for men.
Why Do Many Men Prefer Cialis?
Despite the availability of other options such as Viagra, many men prefer Cialis because timing is not as much of an issue. You don’t have to worry about when to take it. When you use it, it works for three days. There are also men who find that it delays ejaculation, although recommendations are primarily for erectile dysfunction. For these reasons, many men see Cialis as the best option, choosing it over other ED drugs.
What Doses Does Cialis Come In?
When used for erectile dysfunction, Cialis is used in the following sizes of doses:
- 2.5mg;
- 5mg;
- 10mg;
- 20mg;
- 40mg;
- 60mg.
There are recorded cases in which very high doses: 80mg or even 200mg are used, but this should only be done under close medical supervision, since high doses are accompanied by a greater risk of side effects and can lower blood pressure to dangerous levels. Generally, the higher doses are only used to treat pulmonary hypertension, a form of high blood pressure.
Cialis Drug Information
Cialis is identical to Tadalafil in terms of its structure and chemical formula. The only difference between the two products is branding and packaging.
Cialis is substantially different from the other ED drugs on the market on account of its duration. While the effects of Viagra and Levitra only last for about three or four hours, those of Cialis last for a full 24 to 36 hours. For this reason, it is sometimes known as the ‘weekend pill’. A slightly lower Cialis recommended dose can be taken on a daily basis so as to render the user able to engage in intimacy without any preparation.
Tadalafil is sold in the US and the EU under the brand name Adcirca as a treatment for Pulmonary Artery hypertension. It increases dilation of the pulmonary arteries and decreases vascular remodeling, thus reducing chest pain and easing the flow of blood through the heart.
Despite differences in duration, Cialis is similar to other ED drugs in that it is a PDE5 inhibitor. PDE5 inhibitors work by preventing Phosphodiesterase type 5 (PDE5) from degrading a cyclic nucleotide named cyclic Guanosine Monophosphate (cGMP).
When a man who is not suffering from ED experiences sexual arousal, nitric oxide is released in the penis. This causes guanylyl cyclase in the tissues of the penis to become activated; as a result, the level of cGMP increases. Cyclic Guanosine Monophosphate prompts blood vessels to dilate, which increases blood flow to the penis and facilitates erections. One of the most common physical processes underlying ED is the degradation of cGMP by PDE5. PDE5 inhibitors prevent this degradation, thereby supporting the formation and maintenance of erections.
Cialis Dosage Instructions
If Cialis is being taken on an occasional basis, you should ingest your Cialis recommended dose at least 30 minutes prior to physical intimacy.
If Cialis is taken daily, it should, ideally, always be taken at the same time of day.
While the effects of Viagra and Levitra may be delayed by eating certain types of food, a Cialis-recommended dose works without regard to what you eat. However, just as with other ED drugs, combining Cialis with alcohol can be both risky and counterproductive. Cialis and alcohol will be covered in greater detail below.
Cialis Recommended Dose
The Cialis recommended dose for occasional use is 20 mg. This dosage is both safe and effective for the majority of men.
The Cialis recommended dose is considerably lower for daily use. Many men start taking just 10 mg per day.
However, men over 65 may wish to start with a lower dose. Men who are taking any of the drugs Cialis interacts with, men with heart conditions and men with kidney problems face heightened risks when taking Cialis. Therefore, they should consult their doctor before starting to take the drug.
The Maximum Recommended Dosing of Cialis
You should never exceed the maximum recommended dose of Cialis, which is 60 mg. Taking more than the maximum recommended dose of Cialis can be dangerous because of the drug’s effect on blood pressure.
If you take 60 mg of Cialis but do not see positive results, a higher dose is unlikely to work any better. Bear in mind that there are several FDA-approved ED drugs, each of which is effective for approximately 80% of people who take them. If Cialis is not the best option for you, you might wish to try Viagra or Levitra.
If you do not obtain the results you hope for with Cialis, you should be aware that, contrary to popular belief, Cialis (and all other FDA- approved ED drugs) only work when the person in question is experiencing sexual arousal. Drugs such as these assist the flow of blood through the penis, but they cannot create the psychological and physical state of sexual arousal.
What Dose Should I Take?
When asking “What dose should I take?” several factors come into play. Firstly, will you be using Cialis as needed, or will you be using it daily? Since its effectiveness lasts for 36 hours, you can’t take a full “as needed” dose for everyday use.
As a rule of thumb, one should begin with the lowest doses, testing the waters to determine whether it is effective and whether you are subject to any uncomfortable side effects. If it is not effective and there are no side effects, you can cautiously increase your dose. Liquid Cialis is also available, but the same dosage guidelines apply.
Cialis For “As Needed” Use
Dose | Comment |
10mg | Most men are comfortable with this dose for occasional use. It is the normal dose. |
5mg | If mild side effects are experienced, 5mg doses are often sufficient and eliminate this problem. |
20mg | If the 10mg dose is insufficient and there are no side effects, a 20mg dose may prove effective. |
Bear in mind that these doses are for occasional use. If you were to take more than 20mg over a three-day period, you would be at risk of overdose. As with any medication, an overdose can be dangerous.
Cialis for Daily Use
Dose | Comment |
2.5mg | Because Cialis lasts so long in the body, 2.5mg dosages are recommended for daily use. |
5mg | If 2.5mg is not effective enough, and side effects are not present, 5mg doses can be attempted. |
As you can see, doses are reduced, however, these have been proven effective for average men with side effects being relatively rare. Long term use is believed to be safe.
Interaction with Other Drugs
If you take nitroglycerin or organic nitrates for chest pain or organic nitrites (such as ‘poppers’) recreationally, it is important not to mix these drugs with Cialis. This is primarily because of the risk of a sharp decrease in blood pressure. If you take any such drugs, you should consult a doctor before using Cialis or any other ED drug. Moreover, there should always be a gap of at least 48 hours between taking your Cialis recommended dose and taking any organic nitrates or organic nitrites.
Cialis must not be combined with other ED drugs. This is partly because ED drugs have similar effects on the body; their impact is cumulative rather than separate. ED drugs often cause a significant temporary decrease in blood pressure. Taking multiple ED drugs at the same time has the same effect as exceeding your Cialis recommended dose, and it can cause a dangerous fall in blood pressure.
As with other ED drugs, Cialis must not be consumed alongside grapefruit or grapefruit juice. If either of these is in your system when you take your Cialis recommended dose, you may develop a dangerously high concentration of Cialis in your bloodstream. For your safety, you should wait at least 24 hours after ingesting grapefruit or grapefruit juice before taking Cialis.
Possible Contraindications
You should be extremely careful about combining Cialis with any other medications. In addition, there are certain health conditions that preclude its use. If you have any preexisting health condition, or if there is a history of heart attack in your family you should not use Cialis without consulting a doctor first.
We recommend that you go for a check-up even if you are healthy, and that you should discuss Cialis with your doctor. Sometimes, preexisting conditions have not been diagnosed yet, and this could lead to unpleasant effects.
Side Effects
Before looking at the list of side effects, it should be remembered that this drug has been approved under the control of the FDA. That means that it has been exhaustively tested for efficacy and safety. Side effects are rare, and serious side effects are extremely rare, as long as Cialis is used wisely.
Reported side effects include:
- muscle pain;
- bodily aches;
- leg pain;
- heartburn or indigestion;
- runny nose;
- itchy or red eyes;
- flushing;
- headaches;
- nausea.
If you have used Cialis with alcohol and have not limited consumption to no more than two drinks, you may faint owing to very low blood pressure. Cialis does not raise blood pressure, but is not suitable for men with high blood pressure or heart disease without medical advice. Hearing loss is a very rare but serious side effect that requires medical attention. If you have overdosed, you may experience chest pains and heart arrhythmia. In case of these serious side effects, get medical help.
How long do side effects last? Everyone is different, but in case of milder side effects, discontinuing use should ensure relief within a few hours. Full recovery may take as long as three days.
Common Cialis Side Effects
Adverse Reactions Reported by Patients Treated with Tadalafil
Reaction | Placebo | Cialis 5mg | Cialis 10mg | Cialis 20mg |
Headache | 5% | 11% | 11% | 15% |
Dyspepsia | 1% | 4% | 8% | 10% |
Back pain | 3% | 3% | 5% | 6% |
Myalgia | 1% | 1% | 4% | 3% |
Nasal congestion | 1% | 2% | 3% | 3% |
Flushing | 1% | 2% | 3% | 3% |
Pain in limb | 1% | 1% | 3% | 3% |
It should be emphasized that most men who take Cialis do not experience any side effects. This is particularly true among men who stick to their Cialis recommended dose. However, like every medication, there are some side effects.
Some of the more common side effects of Cialis can include flushing in the face, neck and chest, having a clogged or stuffy nose, indigestion, burping, acid reflux and headaches.
Less Common Cialis Side Effects
There are also some less common side effects of Cialis. A small number of people have experienced back pain or muscle cramps 12 to 24 hours after ingesting Cialis. However, these symptoms typically cease within about 48 hours. Moreover, in many cases, these side effects can be reduced or eliminated altogether by sticking to a doctor’s Cialis recommended dose.
As with other PDE5 inhibitors, men taking Cialis may have a very small risk of vision impairment. However, any relationship between Cialis and visual impairment is far from established. The number of people affected is tiny, and almost all of them have had significant risk factors for visual impairment (including diabetes, smoking or hypertension). Thus, although it is possible that Cialis may cause a very small increase in the risk of visual impairment, any such difference appears to be either minimal or non-existent.
Cialis and Alcohol
Drinking alcohol when you have Cialis in your system can be dangerous. This is because both alcohol and Cialis cause blood vessels to dilate and thereby decrease blood pressure. Low blood pressure can result in fainting, dizziness, nausea and blurred vision. Therefore, alcohol consumption should be kept as low as possible when taking Cialis. This is particularly important for people who already have low blood pressure. Although the average man taking Cialis is not very likely to experience problems after consuming one or two glasses of alcohol, having any more than that may cause problems.
Given that Cialis stays in the system of the user for much longer than other ED drugs, you should think about how well Cialis can mesh with your lifestyle before choosing it as your ED drug. If you would like to use ED medication very regularly but also to drink alcohol, Cialis may not be the best choice for you.
Moreover, alcohol also makes it harder to have sex. It is true that alcohol may increase sexual desire through the reduction of inhibitions. However, its physiological effects render erections problematic. In a typical erection, blood is trapped in the penis through the tightening and closure of some blood vessels near the base of the penis. However, alcohol dilates blood vessels, thus making it more difficult for the vessels in the base of the penis to close as they normally would. Thus, even if Cialis is working exactly as it should, alcohol consumption can still hinder intimacy.
High levels of alcohol consumption have been shown to cause ED even after alcohol has been filtered out of the body. Over time, alcohol can cause damage to blood vessels, reducing their capacity to dilate and constrict as needed to create and maintain erections. A full 60-70% of men who are dependent on alcohol suffer from ED.
The Bottom Line on Cialis Dose
Only use Cialis as directed. Be aware that it lasts for three days, and do not take more than the recommended amount during that period. If you want to use it daily, it is safe to do so, but at a lower dose than it would be used for occasional use.
Although side effects are rare, be aware of what they consist of, and self-monitor. To limit the possibility of side effects, stick with the lowest dose that works for you. You can do this by starting low and upping your dose gradually until you obtain the desired effect.
However, if you plan to use Cialis occasionally, you should wait three days before attempting your increased dose, or earlier doses will have a cumulative effect. The same applies to daily use. Use the lower recommended dose for at least three days to allow cumulative effects to kick in before attempting a higher dose.
Cialis is a brand name for Tadalafil, a drug that is used to treat erectile dysfunction (ED). Cialis is extremely popular. It has been taken by over 10 million men in dozens of countries. It is unique among ED drugs on account of its long duration. Cialis was first developed by a biotechnology company named ICOS. It received approval from the Food and Drug Administration (FDA) in 2003 to be sold as a treatment for ED. Tadalafil is also sold under the brand name Tadacip by the Indian pharmaceutical manufacturer Cipla.
