What is Periactin?
This medicine is a type of antihistamine used to treat or prevent various allergy symptoms such as hay fever, nasal inflammation, and runny nose, but it also acts as an appetite stimulant in adults and children. Many underweight people struggling to gain weight have experienced good results with this medication. It’s antiserotoninergic effects also make it suitable as an appetite stimulant.
Merck (the drug manufacturing company producing Periactin) claims it to be the first clinically proven appetite stimulant. Although a number of studies researching the benefits of appetite stimulants have recommended various medications including megestrol (Megace), dronabinol (Marinol), cyproheptadine (Periactin), and thalidomide (Thalomid), which have all shown to be effective appetite stimulants.
Periactin appetite stimulant is not a controlled drug in anyway as it’s only really an anti-histamine. Your doctor can supply you with a prescription or you can get it online.
What are the effects of taking Periactin?
Ok, now about the effects of taking periactin for weight gain. You will be able to sleep at least 10 hours, if not more. The hunger you feel with periactin is very acute the increase in appetite is very noticeable.
Keep in mind that you will not notice the beneficial effects from taking the periactin immediately, but after a few days of repeated use you will begin to experience the increased appetite.
Who should take Periactin?
Periactin is prescribed to patients of all ages. However, I think it would be of great use to younger athletes and other people who are trying to gain weight but don’t have the commitment of working a full time job. Let’s say if you wanted to put on 20 pounds steroid-free, taking periactin seems like an efficient way to gain weight at a rapid rate, since the hunger and the sleep would produce solid weight gain, and this working schedule could accommodate for the increased hours of sleep. You shouldn’t expect pure muscle growth, but you will find your body putting on weight within a relatively short period of time.
Periactin side effects
If you are considering taking periactin, then you should be aware of any adverse side effects. Fatigue and sedation may be associated with Periactin. Many users report the effects of prolonged and deeper sleep. This isn’t necessarily a bad thing when trying to gain muscle. You should review all the potential adverse effects of this medication with your doctor.
How should I take Periactin (cyproheptadine)?
Take this medication exactly as prescribed by your doctor. If the goal is to gain weight then taking 4mg doses on a daily basis will work. Make sure not to take larger doses than recommended and follow the directions on your prescription label.
Is there a generic equivalent available?
Cyproheptadine is the generic version of the appetite stimulant drug Periactin. A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, and intended use. Generic drugs become available on the market when the original manufacturer’s patent expires. Generics are cheaper because generic drug companies don’t have to invest large sums of money to invent a drug, and the savings are passed on to the consumer.

thanks guys for yo updates,i started the drug 2days ago.hoping it will help me
I took this med 40 years ago- I’m 62. Used it for about 7-8 years. I was 5′ 5″ and 105 pounds when I started- that was after having 2 babies. I did have a good appetite, but for all the food I did eat, I just could’nt gain weight. I was never sleepy from this med. The biggest complaint was that I spent so much time eating. I would describe it as being able to eat without ever reaching the point of feeling full. Every meal could be a Thanksgiving feast if you had the time. My afternoon “snack” at work was 6 danishes or pastries. Had a standing order with a deli to deliver them to my office at 3 pm. I spent huge amounts of money on eating.
Toward the end, it was my own aging – going into my 30′s that I cut the daily pill in half. About a year later, I wean myself c ompletely off of them. Now if I eat anything with carbs, I’ll be a pound heavier tomorrow. Enjoy the joys of eating while you can.
Great med!
@Bones u will gain weight all over (however ur body pits on weight)
Anyway, I’m back with an update (been M.I.A. for a while)
I’ve been maintaining at 130-131 since a couple weeks past my last update
I LOVE it!!! I was buying it online because u can buy it online without a perscription -BUT- I Finally got a Doctor to write a perscription for me!!! Way cheaper!!! So, I don’t take them daily anymore maybe like 2x week or if I feel my appetite is slipping.
