Understanding Ronvit Extra Tablets for Allergies

Ronvit Extra tablets combine an antihistamine called cyproheptadine with vitamins to relieve allergy symptoms and correct any nutritional deficiencies. This oral medication fights inflammation in the nose, eyes, throat and skin to manage seasonal or food allergies.

What Conditions Do Ronvit Extra Tablets Treat?

Ronvit Extra tablets are prescribed for relief from:

  • Seasonal allergic rhinitis (hay fever)
  • Year-round perennial rhinitis
  • Allergic conjunctivitis (eye inflammation)
  • Food allergies with mild skin reactions
  • Hives and swelling episodes
  • Cold urticaria rash triggered by cold temperatures
  • Reducing risk of anaphylaxis reactions to medications or bee stings when combined with epinephrine

The antihistamine cyproheptadine blocks histamine receptors responsible for congestion, itching, hives and swelling from allergic triggers. The added vitamins help improve overall health.

How Do the Ingredients in Ronvit Extra Work?

There are two main active components in Ronvit Extra:


  • Prevents histamine from activating inflammatory pathways
  • Reduces mucus secretion, nasal swelling, sneezing and congestion
  • Also has anticholinergic properties that help dry up runny noses and watery eyes


  • Vitamin A – supports immune function, vision and skin health
  • Vitamin D3 – Manages calcium absorption for bone health
  • Vitamin B1 – Breaks down carbs for energy
  • Vitamin B2 – Helps release energy from food
  • Vitamin B3 – Assists processing fats and alcohol
  • Vitamin B5 – Supports stress response and metabolism
  • Vitamin B12 – Forms red blood cells and maintains nerves
  • Calcium – Strengthens bones and aids muscle/nerve signaling

This winning combination fights allergic symptoms on multiple fronts!

What’s the Appropriate Ronvit Extra Dosage?

The cyproheptadine dosage is tailored to each patient’s age, symptoms and response, but common guidelines are:

  • Adults: 4-20 mg daily in divided doses
  • Teens: 4 mg 2-3 times daily
  • Children ages 2-12 Years: 2 mg 2 times daily (Max 0.25 mg/kg/day)

Ronvit tablets come in two strengths – Ronvit Extra containing 4 mg cyproheptadine + vitamins and Ronvit Forte with 8 mg cyproheptadine per tablet. Age-appropriate tablets are prescribed accordingly.

Take the tablets with food to reduce stomach upset risk. Follow up with your doctor if symptoms persist beyond one week of treatment.

What Precautions Should I Know About Ronvit Extra?

  • Avoid operating vehicles or machinery until knowing how drowsiness affects you
  • Use with caution in those with urinary retention issues, seizures, cardiovascular disease or hyperthyroidism
  • Not recommended for newborns, infants or nursing mothers
  • May interact with sedatives, antacids, narcotic pain relievers and antibiotics – Ensure your pharmacist reviews all your medications for interactions

Seek immediate care if you have trouble breathing, sudden swelling or fainting after taking the tablets. These may signal a severe allergic reaction.

What Are Some Potential Ronvit Extra Side Effects?

Common cyproheptadine side effects that often resolve in the first week include:

  • Drowsiness, dizziness, fatigue
  • Dry mouth, blurred vision, ringing in ears
  • Stomach pain, nausea, diarrhea
  • Constipation, increased appetite

Rarely anxiety, irritability, tremors or headache may occur. Discontinue use if any abnormal reactions develop and report them to your physician.

Does It Matter If I Miss a Dose of These Tablets?

It’s best to take Ronvit Extra tablets consistently according to the schedule prescribed by your doctor. This maintains steady symptom relief.

However, if you do miss a scheduled dose, take it as soon as possible. But if it has been over 6 hours since the missed tablet, skip it and just take the next regular one. Do not double up doses or take extra to “make up” for the one you missed.

How Should I Store Ronvit Extra Tablets?

To properly store your tablets:

  • Keep bottles sealed at room temperature below 30°C away from heat and moisture
  • Do not place tablets in bathrooms or humid areas
  • Always keep medication locked away out of the reach of children and pets

If tablets have expired, been damaged or get wet, they may be less effective and should not be taken. Properly dispose per pharmacy instructions.
