Which dosage do I need?

Viagra pills are available in three standard doses: 25mg, 50mg, and 100mg tablets. The optimal dose for each patient depends on his general health and how efficient the drug is for him.

Who can take 50 mg pills?

50 mg is the most popular dosage for Viagra. Your medical advisor may recommend 50 mg if you are using Viagra for the first time. The majority of men find this dose sufficient to resolve their erectile dysfunction and enhance their sexual experience.

Who should use 100 mg pills?

100 mg is the maximum recommended dosage for Viagra. A patient is strongly recommended to avoid taking more than 100mg per day. Such dosages are appropriate for men who don’t get an erection hard enough for sexual intercourse after taking the 50 mg pill. You should start with the 50 mg dose and increase your intake to 100 mg only if the effect is insufficient. Consult your healthcare provider before changing your dosage.

In which cases are 25 mg tablets appropriate?

Viagra 25 mg pills contain the lowest dosage of the active compound. You may be recommended 25 mg tablets when you are taking some other types of pharmaceuticals, including drugs to control HIV or high blood pressure medications, such as alpha-blockers. Taking alpha-blockers together with Viagra increases the risk of adverse effects, including a drop in blood pressure and dizziness. To prevent the harmful interactions, the lower doses of Viagra are more preferable.

Does the required dosage depend on my weight?

At the beginning of your treatment, your healthcare specialist will most likely prescribe Viagra 50mg regardless of your weight.

Does the required dosage depend on my age?

The suitable dosage depends on your overall health and how the drug works for you, rather than your age. There are certain age-related conditions that may affect the dose you need to take. However, there is no general recommendation regarding the dosages to take at specific ages, either.

If the prescribed dosage doesn’t work, can I increase it myself?

If you find that your current dosage is too weak, you should ask your prescribing doctor about increasing it. If you do not suffer from any medical conditions, do not experience adverse effects, and aren’t taking any other drugs, you will likely be allowed to increase your dosage from 50 mg to 100 mg. However, make sure to consult your medical advisor first. In contrast, if you think that your current dosage is too strong, you can lower it without prior consultation to see whether a reduced dose is enough for you.

How often can I use Viagra?

You should not take Viagra more than one time per day. If you have sexual activities more than two times a week, you may also consider other medications, like Cialis daily. It can be taken every day and contains a low dosage of the active compound Tadalafil. The drug is also effective in providing a reliable erection.

What happens if I exceed the dosage?

As with other medications, it is important to keep taking the dose exactly as prescribed. If you take too much Viagra, your risk of side effects will be higher. It could lead to low blood pressure and fainting. Apart from this, you will have a risk of a priapism – the condition when an erection does not go away for more than 4 hours after taking the drug. This condition can cause permanent harm to your penis. If you have accidentally taken an excess dose of Viagra, you should seek medical help immediately.

Can I mix Viagra with other ED medications?

You shouldn’t use more than one erectile dysfunction drug at a given time. Using more than one medication for treating ED will put you at risk of severe adverse effects. If Viagra does not work for you, there are a number of other erectile dysfunction medications and other forms of therapy available, including penile injections or a penis pump. Furthermore, your treatment method will depend on the root of your problem. Thus, counseling is considered to be effective in men who suffer from ED triggered by psychological problems. Maintaining a healthy lifestyle and giving up smoking will also help you enhance your sexual function.

How to Start Sildenafil Treatment

Consult With Your Medical Advisor

Your medical advisor will study your medical history and will recommend the dose of sildenafil he considers right for you.

As mentioned above, for most men, the prescribed dose is 50 mg. Depending on the effectiveness and tolerance to this drug, this dose may be either increased to 100 mg or decreased to 25 mg. You should not take the medication more than once per day. Make sure to inform your healthcare professional about all of the medications you use and all your medical conditions, because they may affect the dose you will be prescribed.

According to statistics, 50 mg or 100 mg sildenafil helps 4 out of 5 men keep erections sufficient for sexual intercourse.

When taking Viagra, you can also do a number of other things to enhance your experience.

Get Into the Right Mood

Simply taking sildenafil will not give you an erection. You have to be sexually stimulated to enjoy the effect of the drug.

Take Your Time

There is no need to rush. Sildenafil usually starts working within 30-60 minutes after taking a pill. However, it can last up to 4 hours, so you have plenty of time for your sexual activity.

Consider What You Eat

Viagra can be taken regardless of food. However, you should not take the medication with a high-fat meal, like a cheeseburger and french fries, because it may impede the effect of the drug.

Research Dedicated to Sildenafil 100 mg and 50 mg

There have been more than 130 clinical studies proving the safety and effectiveness of sildenafil citrate in treating erectile dysfunction.

Research has demonstrated that in most men suffering from ED, 50 mg dosage is effective and delivers a clinically meaningful benefit. Regarding the 100 mg dosage, it turned out that it can give a superior clinical benefit. A comparison of the two dosages showed that a starting dose of 100 mg sildenafil can be a better choice for a patient, as it would minimize the need for titration and could potentially prevent discouragement if 50 mg appears to be insufficient for an optimal sexual performance.

The safety and tolerability of 50 mg and 100 mg sildenafil were also confirmed by multiple studies. The drug is well tolerated in men over 65 years and over 75 years, without an apparent link to cardiovascular events and no additional risks related to non-arteritic anterior ischaemic optic neuropathy, hearing loss, priapism, or drug interactions.

In general, the men who used 100 mg sildenafil for treating ED (compared with those who used 50 mg) were more likely to obtain greater improvement in sexual function and completely hard and rigid erections within 2 weeks of starting the treatment. According to research, the higher dosages should not lead to the big increase in the tolerability risk.



Viagra should not be used under the following circumstances:

  • If you take nitrates that are often administered to treat chest pain, or guanylate cyclase stimulators, such as Adempas, for pulmonary hypertension. These medications taken together with Viagra can cause a critical drop in blood pressure.
  • If you are allergic to sildenafil or any other Viagra ingredient.

Discuss your overall health with your medical advisor to make sure that you are healthy enough for making love. If you suffer from nausea, dizziness, or chest pain during sex, you should seek medical help right away.

Adverse Effects

The most common adverse effects of sildenafil are minor and include dyspepsia, headache, flushing, visual disturbance, and nasal congestion.

However, sildenafil can also cause severe side effects. Although these effects are rarely reported, you should be aware of them and know that you should seek medical help if you experience them.

  • An extended erection or priapism. It is a condition when an erection lasts more than 4 hours. This condition should be treated as soon as possible, because otherwise, priapism could cause permanent harm to your penis.
  • A sudden loss of vision that can happen in one or both eyes. This adverse effect is rather dangerous because it can lead to a serious eye problem that is called non-arteritic anterior ischemic optic neuropathy. If you experience this symptom, you should stop taking Viagra and immediately contact your healthcare provider.
  • A sudden decrease in hearing or complete hearing loss. Some men also report ringing in their ears or dizziness. If you have these conditions, stop taking Viagra and seek medical help promptly.
