Zeagra is an oral prescription drug that is used for the treatment of erectile dysfunction (ED) in men.

The active compound found in Zeagra is sildenafil citrate, which belongs to a group of drugs called PDE5 inhibitors. They are used by adult males worldwide for erectile dysfunction (ED) of any organic cause.

This article covers everything you need to know before taking the drug, such as its mechanism of action, dose, duration, cost, side effects, contraindications, possible drug interactions, and other alternatives.

Let’s get right into it!

What Is Zeagra?

Zeagra is a brand name for the generic drug sildenafil. It is manufactured in India by Zee Laboratories Limited and is exported to many other countries.

Sildenafil is the same compound found in Viagra, the most popular ED medication. It has been the leading product in the ED medication market for the last two decades.

Sildenafil is a phosphodiester-5 (PDE5) inhibitor drug that is used most commonly for the treatment of erectile dysfunction (ED). Erectile dysfunction is the inability to attain and maintain a penile erection for satisfactory sexual intercourse.

Sildenafil helps overcome this inability by dilating and increasing blood flow through the blood vessels and the spongy tissue, corpora cavernosa, of the penis resulting in an erection.

Sildenafil is also used in the treatment of pulmonary arterial hypertension.

What Is the Dose Of Zeagra?

Zeagra is available as oral tablets in doses of 50 mg and 100 mg.

The starting dose is 50 mg but is adjusted according to the response.

Do not repeat the dose before 24 hrs. Always consult your physician before using Zeagra.

How Long Does It Take for Zeagra To Kick In?

Zeagra takes about 30 to 60 minutes to kick in. It can act as fast as 15 minutes and as late as 2 hours.

It is advised to take Zeagra 15 to 30 minutes before indulging in sexual activities.

Do not take fatty meals before taking the drug, as it slows down its absorption and may delay its onset.

However, for the drug to work, sexual stimulation is required.

How Long Does Zeagra Last?

The effects of Zeagra last for about 3 to 4 hours.

How Much Does Zeagra Cost?

Zeagra costs $ 0.4 to $1.05 per tablet. It comes in a strip pack of 4 tablets.

Zeagra is cheaper than Viagra, which costs $70 per tablet.

The History Of Zeagra

Zeagra is a brand name that contains sildenafil, a drug used to treat erectile dysfunction. Zeagra is manufactured in India and is exported to many other countries.

Sildenafil, the active compound in Zeagra, has a history that dates back two decades. In 1989, Pfizer was investigating sildenafil to treat hypertension and heart-related chest pain.

During clinical trials, researchers discovered it was more effective in inducing erections than relieving anginal chest pain. It was then investigated for the treatment of erectile dysfunction.

Extensive research was conducted during most of the ‘90s to establish its efficacy and safety. The FDA approved it for the treatment of ED in 1998.

Pfizer owned the patent since 1998, which expired outside the US in 2012 and in the US in 2020. This has led to the launch of many generic versions that are much cheaper and accessible to everyone.

Who Should Take Zeagra?

Men aged 18 years and above suffering from erectile dysfunction due to any organic cause — such as old age, stress-related, diabetes, obesity, hyperlipidemia, and high blood pressure — can take Zeagra.

Is Zeagra Safe?

Yes, Zeagra is safe.

Clinical trials with a diverse group of men with ED have been conducted to establish the efficacy and safety of sildenafil [2, 3].

Common Side Effects Of Zeagra

The side effects of Zeagra are mostly mild to moderate in severity and usually self-limiting.

Always consult your physician before taking the drug to avoid possible risks and unwanted side effects.

Some common side effects are as follows:

  • Back pain
  • Diarrhea
  • Dizziness
  • Dyspepsia
  • Facial flushing
  • Headache
  • Muscle pain
  • Nasal congestion
  • Palpitation
  • Prolonged erection
  • Rashes
  • Sudden hearing loss
  • Vomiting

Potential Drug Interactions Of Zeagra

Before using Zeagra, make sure you aren’t using the following medications:


Taking nitrates and Zeagra together can lead to a drastic drop in blood pressure. Therefore, taking these two drugs together is contraindicated.


The use of alpha-blockers with Zeagra should be done cautiously, as it can cause a slight drop in blood pressure [4, 5]. Patients should be stable on alpha-blockers prior to initiating Zeagra. Treatment with Zeagra must be initiated at the lowest recommended dose and should be taken 3 to 4 hours apart from antihypertensive medications.

Guanylate Cyclase Stimulators

Taking GC stimulators and Zeagra together is contraindicated because this combination potentiates the former’s hypotensive effects, which can be life-threatening.

CYP3A4 Inducers

These medications induce a faster metabolism of Zeagra by increasing the activity of the enzyme CYP3A4. This can decrease the duration and the effects of Zeagra.

CYP3A4 Inhibitors

Zeagra undergoes extensive biotransformation in human liver enzymes, mainly via the enzyme CYP3A4. Taking CYP3A4 inhibitors with Zeagra leads to an increase in the half-life of the latter by decreasing its metabolism.


A study showed that over 45% of men who took sildenafil with alcohol for recreational purposes had a higher risk of side effects, including facial flushing, headaches, chest pain, changes in vision, and lightheadedness [6].

Who Should Avoid Using Zeagra?

Zeagra should not be used without a doctor’s prescription. Always consult with your doctor first so they can rule out potential risks.

Here are a few examples of conditions in which Zeagra should be avoided:

  • Severe heart disease
  • Severe liver disease
  • History of NAION or “crowded” optic disc
  • Retinitis pigmentosa
  • A history of known hypersensitivity to any PDE5 inhibitors
  • A history of priapism
  • Severe kidney disease
  • Certain blood disorders (hemophilia, leukemia, sickle-cell anemia)
  • Low blood pressure

How Does Zeagra Work?

Zeagra contains sildenafil as an active compound.

Sildenafil is a phosphodiesterase-5 (PDE5) inhibitor drug. It inhibits the enzyme PDE5, which is responsible for cGMP degradation in the corpus cavernosum of the penis.

The Nitric Oxide/cGMP pathway mechanism is responsible for penile erection. The endothelium of the penile arteries produces nitric oxide (NO) in response to sexual stimulation.

NO then travels to the smooth muscles and binds to guanylate cyclase receptors. This leads to the activation of guanylate cyclase (GC). The GC then produces cGMP from GTP.

cGMP is present in high levels after taking sildenafil. The cGMP formed activates cGMP-dependent protein kinase, which, in turn, leads to smooth muscle relaxation and increases blood flow to the penile blood vessels, resulting in an erection. This erection is maintained until sexual stimulation is over.

As Zeagra cannot work without sexual stimulation, take the drug 15 to 30 minutes before sexual intercourse.

Medical Research Involving Zeagra

Zeagra is the generic version of sildenafil. There are limited studies on Zeagra itself. However, the base ingredient of Zeagra, namely sildenafil, has many clinical trials conducted on its safety and efficacy.

Alternatives to Zeagra

There are other prescription drugs and natural alternatives to Zeagra.

Pharmaceutical Alternatives to Zeagra

Several medications for ED can be purchased online or from local pharmacies. While the mechanism of action is similar for most drugs, they differ in cost and dosage.

Other prescription-only drugs used for ED include:

  • Avanafil (Avaforce, Stendra, Avana)
  • Mirodenafil (Mvix)
  • Tadalafil (Cialis, Adcirca, Vidalista, Tadacip, Forzest, & more)
  • Vardenafil (Levitra, Staxyn, Vilitra, Zhewitra, Savitra, & more)

Natural Alternatives To Zeagra

Many herbs and nutrients have long been used to help facilitate an erection. These herbal compounds are effective but also come with a risk of side effects.

Horny Goat Weed (Epimedium spp.)

Horny goat weed can help treat ED by increasing NO synthesis,  enhancing smooth muscle proliferation, and mimicking endogenous androgens [10].

Ginseng (Panax ginseng)

Studies show Korean red ginseng’s benefit for ED [7, 8]. It works by inducing the release of NO and relaxing the smooth muscles of the corpus cavernosum.


L-arginine supplements can be an effective therapy for ED, as per multiple studies [9].

Muira Puama (Ptychopetalum olacoides)

It is an herb that can enhance libido and induce penile erections by activating hormones like testosterone.

Where To Buy Zeagra?

You can buy Zeagra with a doctor’s prescription from your local pharmacy. You can also buy Zeagra from an authorized online store selling pharmaceutical products.

Buying it online is preferred by most people as it is discreet, cheaper, and more easily accessible.
