Zenegra is a medication used to treat erectile dysfunction (ED) in adult men. It belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Its active ingredient is sildenafil citrate, which works by increasing blood flow to the penis, enabling a man to achieve and maintain an erection during sexual stimulation.

Zenegra is manufactured by Alkem Laboratories Ltd and is available in tablet form. It is a generic version of the well-known medication Viagra, which means it contains the same active ingredient and has similar effectiveness and safety profile.

Do’s and Don’ts

Before taking Zenegra, it is important to consider certain contraindications:

  • Do not take Zenegra if you are allergic to sildenafil or any other ingredients in the medication.
  • Do not take Zenegra if you are currently taking any nitrate medications, such as nitroglycerin, as this can lead to a severe drop in blood pressure.
  • Do not combine Zenegra with any other PDE5 inhibitors, as this can increase the risk of side effects.
  • Do not take Zenegra if you are using recreational drugs, such as “poppers,” which contain nitrates.
  • Discuss your medical history and any existing health conditions with your doctor before starting Zenegra, especially if you have cardiovascular problems, liver or kidney disease, or a history of priapism (painful erections lasting longer than 4 hours).

Potential Side Effects

Like any medication, Zenegra can cause side effects, although not everyone experiences them. Common side effects include:

  • Headache
  • Facial flushing
  • Upset stomach
  • Nasal congestion
  • Blurred vision

These side effects are usually mild and temporary, resolving on their own. However, if they persist or become bothersome, it is important to seek medical advice.

In rare cases, Zenegra can cause more serious side effects, such as:

  • Prolonged and painful erection (priapism)
  • Sudden decrease or loss of vision
  • Sudden decrease or loss of hearing
  • Chest pain or irregular heartbeat
  • Allergic reactions characterized by rash, itching, or swelling

If you experience any of these serious side effects, stop taking Zenegra and seek immediate medical attention.

Zenegra Dosing

The recommended dose of Zenegra is 50 mg, taken orally as needed, approximately one hour before sexual activity. Depending on individual response and tolerability, the dose can be increased to 100 mg or decreased to 25 mg. The maximum recommended dosing frequency is once per day.

If you miss a dose of Zenegra and still plan to engage in sexual activity, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.

It is important not to exceed the recommended dose of Zenegra, as this can increase the risk of side effects. If you accidentally take more than the prescribed amount, seek medical advice.

Drug Combinations

Zenegra can interact with certain medications, potentially leading to adverse effects or reducing the effectiveness of the drug. Inform your doctor if you are taking any of the following:

  • Nitrates or nitroglycerin
  • Alpha-blockers such as doxazosin or tamsulosin
  • Antifungal medications like ketoconazole or itraconazole
  • HIV protease inhibitors such as ritonavir or saquinavir
  • Macrolide antibiotics like erythromycin or clarithromycin

Your doctor will determine whether it is safe for you to take Zenegra while using these medications or if any dose adjustments need to be made.
