Generic medications with Sildenafil Citrate as active ingredient are produced and distributed under different names. One of them is Happigra from South Korean manufacturer Samjin. The main purpose of Sildenafil Citrate is treating erectile dysfunction (ED) and its presence on the market is increasing constantly. Successful treatment of erectile dysfunction provides less stress and better life for all affected men.

Sildenafil Citrate has proved its efficacy in many clinical trials and a lot of satisfied patients continuing to use drugs with this ingredient. It belongs to the class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, so they stop the enzyme phosphodiesterase type 5 in blood vessel walls and cause blood vessels relaxation which increases blood flow to the lungs and penis.Because of the effect in blood vessels of the lungs, this drug can be used also for pulmonary hypertension (PH).

Customer Reviews

Happigra is a generic brand of Viagra produced in South Korea, but there are no customer reviews for this brand available online. The fact that there are a lot of fake drugs being sold online makes people scared and not sure of buying drugs for erectile dysfunction which are less recognized than Viagra. Customer reviews for this type of medication can ensure the patients and give them self-confidence to start treatment for erectile dysfunction with some particular brands.

We have not found enough information about this brand’s safety and efficacy profile as well as the credibility of its manufacturer. There are a lot of high rated popular generic brands of Sildenafil available on the market, and you can try any of them instead of Happigra. Consultation with a doctor for starting the treatment of erectile dysfunction, doses and side effects of the drug that is going to be used is recommended.

Pricing and Dosage

Usual recommended dose is 50mg once a day in men over 18 years with erectile dysfunction. Increasing the drug maximum to 100mg once a day should not be exceeded. The doctor can decrease the dose to 25mg once a day when there is an indication for that, like liver, kidney or heart diseases.

We can’t find the actual price of the brand Happigra online, so there are no recommendations for any website where it can be purchased.

How to Buy Happigra UK Online

Viagra and many other products with Sildenafil Citrate can be easily purchased online from different websites. In this case when we were looking for online purchasing of Happigra there are no actual websites that are selling this brand.

How to Use

This medication for treating erectile dysfunction is for men only. Women and young men under 18 years should not use any of this impotence medication with Sildenafil Citrate as main ingredient.

One hour before sex action starts, the drug should be taken orally with a glass of water, but the effect can be reached with sexual stimulation. This medication is for once a day usage and it is not to be used in combination with other drugs for treating erectile dysfunction. Duration of its effect should not be more than 4 hours; otherwise the patient must inform his doctor immediately.

Consultation with physician is suggested, especially when the patient takes prescription medications for similar or any other purpose.

Side Effects

Common side effects include headache, visual disturbance, insomnia and facial flushing. All of these side effects are short termed and they are not treated as threat for a patient.

Some rare side effects like increased blood pressure, pain in chest, prolonged and painful erection (more than 4 hours), vertigo, eye pain or muscle pain can occur.


The pharmaceutical company from South Korea, Samjin, produces a generic pharmaceutical product of Viagra. The brand Happigra contains Sildenafil Citrate as its active ingredient and it is targeted for erectile dysfunction. This sexual problem can be solved in many cases by using Happigra or other medication with Sildenafil Citrate.

We can’t recommend the brand Happigra for patient as a first choice in the treatment of erectile dysfunction, because there are no customer reviews online and we can’t be so sure about its efficacy.

This company was founded in 1968 and it is operating for about half a century with lots of achievements, but we can’t rely on these facts only. It is easy for patients when they can find other customers comments who have tried the brand and report it beneficial. We rate this brand Happigra, 2 on a scale of 1 to 5 and consultation with doctor before using it is recommended.
