Cyproheptadine Hydrochloride History
Cyproheptadine hydrochloride is an early anti-histamine drug, and has been sold as a prescription medication in most developed nations for decades. It was introduced to the U.S. in 1961 under the Periactin brand name by Merck & Co. This brand of cyproheptadine hydrochloride was sold for many years in the U.S, but was voluntarily discontinued by Merck in 2003 (in both the U.S. and Canada). While Merck & Co. has withdrawn Periactin from a number of other nations (likely due to low financial interest), the brand is still sold in more than one dozen countries including Australia, Austria, Belgium, Ireland, Italy, Netherlands, New Zealand, South Africa, Spain, Sweden, Thailand, and the United Kingdom. It is also sold under dozens of other brand names around the world, in both singleand multi-ingredient preparations. A number of generic products are still sold in both the U.S. and Canada as well. Subsequent to studies questioning the long-term weight gaining value of cyproheptadine hydrochloride therapy, in 1994 the World Health Organization warned against using the drug for this purpose. Regardless of this report, many still support the value of cyproheptadine hydrochloride as a short-term appetite stimulant.
How is Cyproheptadine Hydrochloride Supplied
Cyproheptadine hydrochloride is most commonly supplied in tablets of 4 mg.
Structural Characteristics of Cyproheptadine Hydrochloride
Cyproheptadine hydrochloride is antihistaminic and antiserotonergic agent with the chemical designation 4- ( 5H - dibenzo [a,d] cyclohepten - 5 - ylidene) - 1 - methylpiperidine hydrochloride sesquihydrate.
Cyproheptadine Hydrochloride Side Effects
As a first-generation anti-histamine, cyproheptadine hydrochloride may be prone to producing a number of side effects in its users. The most common of which is sedation or the classic “anti-histamine lethargy”, which is common to these types of drugs. For some users, the tiredness that cyproheptadine hydrochloride will produce will outweigh any potential as a weightgaining/performance-enhancing agent. For most, this side effect of cyproheptadine hydrochloride is not very noticeable, and perhaps a nuisance (not strong enough to an ingredient. necessitate discontinuation) at best. Other less common side effects of concern include, but are not limited to, dizziness, disturbed coordination, muscular weakness, nausea, vomiting, diarrhea, constipation, dryness of the mouth, difficulty urinating, vertigo, blurred vision, tightness of the chest, wheezing, stuffed nose, sweating, early period, headaches, and faintness. Any strong incidence of unwelcome side effects would immediately warrant discontinuing the drug, or even seeking immediate medical attention if severe.
Cyproheptadine Hydrochloride Administration
The dosage required for medical purposes may vary depending on the individual and their particular needs. The established therapeutic range for cyproheptadine hydrochloride is 4 mg to 20 mg per day, with most adults requiring 12 mg to 16 mg daily. The total daily dosage is usually divided into three separate applications. When used (off-label) as an appetite stimulant, a dosage of 4mg is commonly taken 2-3 times per day (8-12 mg). Above this level, side effects may become more noticeable (most notably sleepiness), often interfering with the benefit of the drug.
This may be used during a steroid cycle focused on bulking, with the intake of cyproheptadine hydrochloride usually lasting no more than 4-8 weeks. For those who tolerate this anti-histamine’s side effects (mainly tiredness), cyproheptadine hydrochloride is often reported to offer significant value as an appetite stimulant during weight gaining cycles. This is especially so in individuals that have trouble eating enough food to meet the high calorie/protein requirements for optimal muscle growth.
Cyproheptadine Hydrochloride Availability
Cyproheptadine hydrochloride is produced in a wide number of countries. Although it is not commonly traded on the black market, high supply and the relatively benign nature of this drug (loose controls) make it easily diverted for sale when needed. Given its low demand, counterfeiting of cyproheptadine hydrochloride preparations is not common.
It is interesting to also note that the Dominican steroid product, Anabolex, actually includes 1.5 mg of cyproheptadine hydrochloride in each 3 mg methandrostenolone tablet, which was added by its developers to facilitate increased caloric intake and weight gain during anabolic therapy. The 2:1 ratio provided is optimal for a daily dose of 24 mg Dianabol (a very common amount), as it would provide 12 mg of cyproheptadine hydrochloride (the maximum common daily dose). This is the only common anabolic steroid product that includes cyproheptadine hydrochloride as an ingredient.
