What is Apetamin?
Apetamin is a syrup or tablet marketed as a non-surgical, figure-enhancing supplement. Its main ingredient is cyproheptadine, an antihistamine that increases the appetite but is dangerous in high doses. Taking too much cyproheptadine may result in liver damage, extreme drowsiness, delirium, or seizures.
Why do people take Apetamin?
Social media promises a “slim-thick” figure when taking Apetamin. However, successfully achieving those results has been inconclusive and anecdotal. Cyproheptadine is known to help with weight gain off-label, but the best dosage or duration to achieve a desired physique isn’t known.
Going for the figure social media advertises by misusing it may not only be dangerous but unsuccessful.
Other Ingredients in Apetamin
Alongside cyproheptadine, Apetamin also contains the amino acid lysine and a mix of vitamins like B1 and B6. The vitamins have led marketers to advertise Apetamin as a “vitamin supplement” when the actual active ingredient is an antihistamine.
Lysine, on the other hand, is an essential amino acid that the average American consumes plenty of regularly. There’s no need to supplement it into the diet with Apetamin.
As Apetamin is unregulated, there’s no way to guarantee what other ingredients may be in it or its safety.
What is cyproheptadine?
Cyproheptadine is a first-generation antihistamine prescribed in the United States to relieve minor allergy symptoms. It was developed in the 1960s alongside other antihistamines like Benadryl and Dramamine that cause drowsiness (or occasional excitability in children). It now has other uses besides allergy relief.
As one of cyproheptadine’s main side effects is drowsiness, those unaware of how cyproheptadine affects them should use caution in daily activities as the drowsiness could impair their judgment. As there’s no knowing how much of it is in Apetamin, it’s difficult to anticipate how severe the side effects will be, which could result in a potentially dangerous situation.
What is cyproheptadine used for?
Cyproheptadine has several uses, including treating mild allergic reactions and off-label indications for migraines and increasing the appetite of malnourished patients. It’s also been used for motion sickness, and researchers are continuing to investigate its possible use for treating Serotonin Toxicity, a possible symptom from Selective Serotonin Reuptake Inhibitors (SSRIs) overdose.
Cyproheptadine is a hepatotoxin, meaning it’s toxic to the liver in high doses. Taking the doctor-prescribed dose is fine, but misusing it may lead to injury. A woman who drank Apetamin syrup daily for six weeks developed autoimmune hepatitis.
As Apetamin is unregulated, there’s no knowing how much cyproheptadine is in each dose, and it’s unknown whether social media sellers properly communicate the risk for this serious side effect. As with all unregulated products the quality and quantity of the ingredients cannot be verified.
What are the side effects of cyproheptadine?
Typical side effects of cyproheptadine are:
- Drowsiness
- Dizziness
- Constipation
- Dry mouth
- Blurred vision
Misuse or overdose symptoms are:
- Mood changes
- Hallucinations
- Decreased breathing
- Increased heart rate
- Possible liver damage
- Seizures
- Coma
Can you overdose on Apetamin?
If the concentration of cyproheptadine is high enough in Apetamin, then it’s possible to overdose. There may be other unknown substances in Apetamin which could have their own side effects. Additionally, cyproheptadine interacts negatively with alcohol, anxiety medications, and other nervous system depressants.
