Features of Caverta

Caverta is a treatment medication used to improve symptoms of erectile dysfunction (ED).

This product contains the same active ingredient as the globally renowned ED treatment Viagra, and is characterized by its red triangular tablets.

Manufacturer of Caverta

Caverta was originally developed by Ranbaxy and is now produced and sold by Sun Pharma as a generic version of Viagra.

These two India-based generic pharmaceutical companies saw Japan's major pharmaceutical company "Daiichi Sankyo" complete its acquisition of Ranbaxy in 2008.

The acquisition aimed to utilize Ranbaxy's sales network covering over 150 countries to further develop pharmaceutical business.

In 2014, Sun Pharma announced its merger with Ranbaxy, now becoming the world's fifth-largest and India's largest generic pharmaceutical company.

Efficacy of Caverta

The active ingredient in Caverta, sildenafil, works by inhibiting PDE-5 (phosphodiesterase type 5), which causes erectile dysfunction.

The enzyme PDE-5 breaks down cyclic guanosine monophosphate (cGMP), which is necessary to maintain an erection.

When cGMP is excessively broken down, it leads to the inability to achieve a proper erection, a condition known as ED (erectile dysfunction).

Sildenafil works by inhibiting PDE-5 enzyme activity, expanding blood vessels in the penis and relaxing smooth muscles in the corpus cavernosum.

This mechanism allows more blood to flow into the corpus cavernosum, thereby promoting erection.

Duration of Caverta

The effects last for 4-6 hours, but please note that taking the medication does not force an erection—sexual stimulation is still required.

Dosage and Specifications of Caverta

Sildenafil 50mg/100mg.

First-time users are advised to use a pill cutter to split the tablet and start with half a dose.

Differences Between Caverta and Other Viagra Generics

Apart from Caverta, there are Viagra generics produced by multiple manufacturers in the market.

While they are all generic versions of Viagra, there are both similarities and differences among them.

All Viagra generics contain the same active ingredient, sildenafil.

There is no difference in basic efficacy, and similar ED improvement effects can be expected.

Noteworthy are the differences in excipient ingredients.

Excipients are used as coating materials to protect the active ingredient from stomach acid.

However, even among similar generics, differences in excipients may lead to variations in how the drug works and how side effects manifest.

Therefore, if Caverta proves ineffective, you may try switching to another generic, and vice versa.

Other Information

This distinctive red tablet with remarkable ED treatment effects is a high-quality generic version of Viagra.

Administration Method & Usage Instructions

Timing of Administration

The correct way to take Caverta is on an empty stomach, 1 hour before sexual activity.

After the first dose, if a subsequent dose is needed, wait at least 24 hours.

Recommended Dosage

Caverta sold on our site comes in 50mg/100mg tablets. Using a pill cutter, these can be halved to take as a half dose.

If 25mg shows insufficient effect, gradually increase to 50mg or 100mg. Adjust the dosage to suit your individual needs.

Note: Some users take 2-3 times the recommended dose for stronger effects, but this does not enhance efficacy.

Do not exceed 50mg per single sexual activity.

For smaller individuals, 25mg/50mg may suffice.

Caverta with 100mg active ingredient is suitable for larger-built foreign men.

Recommended Initial Dosage

When taking Caverta (containing sildenafil) for the first time, start with 25mg.

Food Interactions

It is advised to remain fasting for 2 hours before taking the medication.

This relates to the absorption process of sildenafil (Caverta's active ingredient):

Sildenafil must be absorbed through the intestines into the bloodstream.

If food is present in the stomach, the tablet may be absorbed by the stomach before reaching the intestines.

Additionally, if high-fat meals are consumed before taking the medication, fats may adhere to intestinal walls, reducing absorption rates.

Poor absorption can lead to lack of effect or insufficient efficacy—always take on an empty stomach.

Absorption occurs within 30 minutes; eating afterward is acceptable.

Alcohol Interactions

While Caberta can be taken with alcohol, note: vasodilation effects may accelerate intoxication—avoid excessive drinking.

Contraindications

• Patients with cardiovascular disease (heart or vascular disorders) who are not suited for sexual activity
• Those with severe liver dysfunction
• Individuals with hypotension or uncontrolled hypertension
• Those with a history of stroke, cerebral hemorrhage, or myocardial infarction within the past 6 months

※Always follow your doctor's instructions when taking this medication.

Side Effects

Main Side Effects

The primary side effects include lowered blood pressure due to vasodilation, eye congestion, facial flushing, heart palpitations, nasal congestion, etc.

These side effects are caused by the vasodilation effect and may alleviate as increased blood flow to the penis occurs with enhanced sexual desire.

Special Symptoms

Unusual visual disturbances may occur, such as a bluish tint to vision or difficulty distinguishing between blue and green.

Most cases are temporary and not concerning, but if significant vision loss occurs, there is a risk of non-arteritic anterior ischemic optic neuropathy (NAION).

If sudden vision deterioration or loss occurs, consult an ophthalmologist immediately.

Additionally, if a painful erection persists for over 4 hours, there may be a risk of priapism.

If the erection lasts beyond 4 hours, seek immediate medical attention.

※What is non-arteritic anterior ischemic optic neuropathy (NAION)?
A condition where blood supply to the optic nerve is disrupted, leading to dysfunction or necrosis of optic nerve cells.

※What is priapism?
Priapism refers to a prolonged, often painful erection that does not subside naturally. This condition is also known as penile rigidity disorder.

The primary cause is considered to be dysfunction in the arterial system of the penile corpus cavernosum.
