How Long Should Sildenafil Citrate 100mg Tablet

Sildenafil Citrate 100mg medications come in the form of tablets, that have to be taken when an individual experiencing erectile dysfunction plans to engage in sexual interaction. Such individuals may struggle to get and maintain erections due to their sexual weakness. This weakness is caused due to the lack of blood circulation to the penile organ, which happens because of the building up of plaque in the passages of the penile arteries. The plaque formation clogs the arteries and blocks the supply of blood to the penile, which is why men find difficulties with their erectile function.

Ed Medications

If you are one among those individuals that suffer from such sexual difficulties, then you may try out some remedial solutions like ED medications. This remedy is the safest among other treatment options for erectile dysfunction. Ed medications contain an active ingredient that performs a key role in improving sexual difficulties. Sildenafil Citrate is the active ingredient, that is present in Viagra medications, which is the popular medicine for erectile dysfunction. Viagra is an FDA-approved drug, which indicates its safety and reliability for use among individuals with impotence issues.


Since prescription-only medication like Viagra is approved by the FDA, which is nothing but a brand name version of Sildenafil, one can conclude that Sildenafil Citrate is a safe and effective solution for impotence issues. There are many generic versions of Sildenafil Citrate medications available, which can be bought without needing any prescription. One such version of them is Fildena, which helps in reviving sexual function within a few minutes of consumption. 

Action mechanism of Sildenafil Citrate

Sildenafil Citrate 100mg is a high-dose drug, which is suitable for the treatment of moderate to severe forms of erectile dysfunction problems. The Sildenafil Citrate component is categorized under phosphodiesterase type 5 (PDE5) inhibitors, as per the pharmacological classification. PDE5 inhibitors are responsible for inhibiting the action of PDE5 enzymes, which are found in the walls of the penile arteries. PDE5 enzymes give rise to erection difficulties by depleting the nitric oxide in the arterial walls of the penile.

Nitric Oxide

A powerful chemical like nitric oxide is needed for the optimal functioning of the penile arteries. It causes the synthesis of cGMP enzymes, that conduct vasodilation and expansion of the narrowed and strained penile arteries. The release of cGMP enzymes causes the relaxation of the arteries, which leads to an increase in blood circulation through their passages. As more and more blood flows to the penile, the ability to attain and sustain erections improve. Thus, Sildenafil Citrate 100mg restores optimal sexual function.

Sildenafil Citrate consumption pattern

These medications are composed in tablet form. A single tablet must be taken only when you plan to get into sexual interaction. Take the tablet for around 30 to 45 minutes before you get intimate. It must be swallowed with some water. Make sure you do not crush, break, or chew the tablet and change its form before consuming it. It is recommended to swallow it as-a-whole, to retain its effectiveness. 

A single pill is enough for a day. Never take this pill more than once within a 24-hours duration. This is a high-dose pill, which can remain active in the body for a long time. So, avoid overdosing yourself.

Sildenafil Citrate effectiveness

The 100mg strength of these medications works on severe degrees of impotence issues in men. The effects of these tablets last for around 6 to 8 hours in the bloodstream. These pills are not necessarily for regular consumption unlike other medications used for treating chronic conditions. This medicine can be used only when required, otherwise, there is no need for taking them unnecessarily.

Moreover, these impotence-treating medications are not for long-term usage. One cannot keep using them permanently. It can be used unless and until the erection function gets restored.  

Sildenafil (Viagra) Vs Sildenafil generics

Although the active ingredients among these ED medications are the same and they may even produce the same effects, still they differ in their cost. This is so because Viagra medications acquired FDA approval long ago. For getting the approval, strong and extensive research backing along with clinical evidence is a must and Viagra pills have proved the same. But generic versions of them lack such research and clinal support, as adequate research is already done by already existing Viagra pills. This does not make generic medications less effective. Since the active component remains the same, thus, they both produce identical effects and offer the same benefits in restoring the erection function.

Side effects associated with sildenafil citrate  

Some mild side effects due to these high-dose ED medications may include headaches, nausea, rashes, lightheadedness, stomach discomfort, blurred vision, nasal congestion, flushing, back pain, muscle pain, stomachache, and dizziness. These mild effects are nothing to worry about as they remain for a brief period and disappear as the body adjusts and becomes used to the medicine. But, if the symptoms stay for a notable period and do not go away, get them checked with your doctor.  


  • Never do some intense activity after taking these medications. The effects of Sildenafil can cause dizziness to some extent, and some may even experience blurry vision.
  • Alcohol can impact the effectiveness of the medication. One might even develop side effects due to their interaction. So, it is better to avoid their combination.
  • Give up your plans on driving or doing some work related to operating heavy machinery, as the medicinal effects can affect your alertness and cause dizziness.
