Review and Description

Siegfried Rhein is a pharmaceutical company in Mexico, but it was founded in Switzerland in 1873. This company was set in Mexico in 1973 and it is now one of the leading pharmaceutical companies there. This Mexican pharmaceutical company offers 89 products that provide treatment of different diseases, which can improve the health and the quality of life.

Lerk is one of the products from this Mexican pharmaceutical company, which is used in treatment of erectile dysfunction. It is a generic drug of Viagra using the active ingredient Sildenafil Citrate in its composition.

Sildenafil Citrate has proven effectiveness in treatment of erectile dysfunction and giving ability for normal duration of erection for sexual intercourse. It relaxes the blood vessels in penis, thereby increasing blood flow through this organ and ensuring a normal erection. There are 2 types of this brand: Lerc® (oral tablets) and Lerc® Jet (chewable tablets).

Customer Reviews

Looking for customer reviews online not always ends successfully. There are a lot of generic drugs from different manufacturers used for erectile dysfunction (ED) treatment that are not mentioned in one single review. That is the case with this brand Lerk, so the absence of customer reviews makes its safety and efficacy doubtful. Most of the men that have this problem of ED want to know more about the medicine before taking it to prevent from unwanted side effects that can increase the stress and won’t let them enjoy sexual activity. Therefore, customers usually trust the brand that is most common and well known even though there are brands with the same efficacy, good quality and lower price.

Pricing and Dosage

The brand Lerk is produced in two different type of tablets: oral tablets and chewable tablets, which can be found with 50mg and 100mg Sildenafil. The price we have found online is 171$ for a package of 4 tablets Lerk jet 50mg chewable tablets.

How to Buy Lerk Sildenafil 100mg Online

Lerk can be purchased online only for internal delivery. There are several online shops where this medicine can be found, but the prices and shipment are different. Also the time of delivery is different.

For erectile dysfunction, recommended dose of 50 mg is the starting dose to be taken, on demand basis. This initial dose should be followed by a maintenance dose of 25 mg to 100 mg. The maintenance dose depends on the penile response of the patient. The drug should be taken before 1 hour of starting sex. The dose of Lerk should be adjusted in special population like patients with kidney and liver disorder.

How to Use

Usually Sildenafil Citrate is produced as coated tablets, but the Mexican pharmaceutical company, Siegfried Rhein, released two forms at the market: oral tablets and chewing tablets. Both forms should to be used about 1 hour before starting the intercourse in combination with sexual stimulation.

Taking this tablet in combination with alcohol or heavy meal can prolong the start of the effect or cause erection that don’t last enough for complete sexual satisfaction of both partners.

Doctors always recommend that patient should start with dose of 50mg Sildenafil once a day, but that dose can be increased to 100mg Sildenafil a day if the doctor thinks it’s necessary. Recommendation for decreasing the dose is usually because of some additional conditions in patients.

Side Effects

Patients with this kind of sexual inability probably won’t say that having a light headache is an important side effect if they achieve their wanted condition. Beside this most common side effect (headache), there are some other side effects that can occur: facial rush, vision effects, insomnia, sometimes even pain in the chest or eyes.

If some serious side effects occur, the patient must immediately inform his doctor.


Starting the production of brand Lerk in Mexico offers the population suffering from erectile dysfunction another opportunity to cure this problem and have normal sexual intercourses. One of the biggest problems that makes us skeptical about this brand is the fact that we can’t find any customer reviews available online for it, so we are not confident about its true potential.

The company Siegfried Rhein offers the patients brands with high quality and safety and develops innovative products that can help in treating different diseases. The combination of certified company with experience and absence of customer reviews lead us to rate this brand with 2 on the scale of 1-5. Sildenafil has proven its efficacy, but it is important to consult your physician before starting the treatment with this or any other brand.
