Introduction

Peritol is a brand name of Cyproheptadine. It has many actions, but one of most commonly utilized is its serotonin antagonist action. This action makes it a good appetite stimulant. In addition, Peritol inhibits histamine receptors. Therefore, it works as an anti-histamine medication, such as Piriton. Pertiol also causes drowsiness and helps to induce sleep. Anti-histamine indications are common colds and allergies.

Peritol should not be used for sleep. Other medications should be used for sleep problems.

Common uses of Peritol

  1. Appetite stimulant
  2. Anti-histamine (common cold, allergies)
  3. Sleep-inducing agent - effect wanes after some time
  4. Treatment of drug-induced akathisia - a troublesome side effect of some anti-psychotic medications.

How to use peritol

Usual dosage of peritol is 4mg thrice daily. That is 10ml of peritol syrup thrice daily.

What are the side effects of Peritol?

Main side effect of peritol is its ability to cause drowsiness and sedation. This action makes driving vehicles and operating machinery dangerous. In addition, drowsiness goes into next day morning and to make waking early morning difficult.

Peritol can cause weight gain due to its ability to increase appetite. In addition, using Peritol to induce appetite in a patient with an underlying disease (cancer) without investigating the cause for loss of appetite can be dangerous. In some countries this medication is available over the counter.

Other common side effects of Peritol

  • Headache
  • Psychomotor impairment
  • Urinary retention
  • Dry mouth
  • Blurred vision
  • Gastro-intestinal disturbances

Rare side effects of Peritol include low blood pressure, palpitations, arrhythmias, dizziness, confusion, depression, sleep disturbances, tremors, fits, liver problems, and angle-closure glaucoma.

Peritol is available as tablets, capsules and syrups. It should ideally be taken in the night. Elderly people will get most of the side effects. In addition, it is not recommended to use Peritol in children.

Who should not use Peritol

This drug should not be used in patients with prostatic hypertrophy, urinary retention, in people susceptibility to angle-closure glaucoma, and in intestinal obstruction. Peritol should not be taken if you have liver diseases. It is because peritol can induce coma in liver failure. In addition, taking peritol to induce appetite without seeking a cause for appetite loss can be dangerous (some chronic diseases can cause appetite loss such as Tuberculosis).

Pregnancy and breastfeeding

Peritol should be avoided in pregnancy. Newborn irritability, paradoxical excitability, and tremor can occur following delivery. In addition, Peritol should not be used in mothers who are breastfeeding.

Summary

Peritol is a common over-the-counter appetite stimulant. However, it can cause some problematic side effects, such as drowsiness.

Drowsiness is a main side effect of Peritol that can cause serious injuries when driving.

      Yes you will again lose appetite. If you have continuous loss of appetite then you need to be examined by a doctor for serious physical or mental health issue. Peritol is only temporary solution.
