FAQ
What Periactin 4mg pack sizes can I order?
Periactin comes as 4mg tablets in packs of 30 to 360. The pack contains generic cyproheptadine, not the original Periactin. Larger packs cost less per tablet.
How is Periactin delivered to Hong Kong?
If your Periactin parcel does not arrive within the delivery window, or arrives damaged, it is sent again free; if that is not possible, the order is refunded. Support answers 24/7 in English and Cantonese by live chat.
What is another name for cyproheptadine?
Periactin is a brand name of cyproheptadine, which is also sold as Ciplactin. Here, cyproheptadine can be bought online as generic Periactin. These are generics, not the original brand.
Can I drink alcohol with Periactin?
Alcohol and cyproheptadine both slow you down, so a drink with your dose can make you sleepier and dizzier than the tablet would alone. Wait until you know how Periactin affects you before mixing the two, and certainly before driving or working.
Will Periactin make me sleepy?
Yes, it is the most common effect, and the reason Periactin is not one of the non-drowsy antihistamines. How heavy it feels differs between people, and it can last as long as you keep taking the tablets. Hold off on driving or machinery until you have seen how one dose affects you.
Does Periactin increase appetite?
Often, yes. Cyproheptadine is one of the antihistamines known to stir up appetite, and it has been used on purpose to help people eat more. Longer courses can lead to weight gain, so the change in appetite is worth expecting rather than being surprised by.
What else is cyproheptadine used for?
Beyond allergy symptoms, the same ingredient is used for certain headaches, including migraine, and for Cushing's syndrome, where the body produces too much of its own steroid hormones. Both are separate from the allergic rhinitis and hives that these 4mg tablets are sold for.
Does Periactin come as a liquid?
Cyproheptadine is also made as an oral liquid in some countries, but the listing here is the 4mg tablet only. Tablets are swallowed with water, which makes them easy to carry and take when you are away from home.
About Periactin
What Periactin 4mg tablets are used for
Periactin is cyproheptadine 4mg tablets, an antihistamine for the symptoms of allergy: a runny nose, sneezing, an itchy nose or throat, and red, itchy, watery eyes. It also calms the itch of allergic skin conditions, and hives — urticaria — are the other common reason people take it. First-generation antihistamines such as this one are sedating rather than non-drowsy, which is the main thing to know before you order.
Cyproheptadine blocks histamine, the substance the body releases when it meets something it reacts to. It also damps down serotonin, a chemical messenger involved in appetite, mood and sleep, and that is why it behaves differently from a modern hay-fever tablet: it tends to bring on sleepiness and hunger rather than leaving you clear-headed. The drying effect that eases a runny nose is also what leaves the mouth and throat dry. The cyproheptadine ingredient page covers the ingredient itself.
How Periactin is taken
Swallow a tablet with water, two or three times a day, at roughly the same times each day. No food rules go with cyproheptadine, so carry on eating as normal. The 4mg strength is the one sold here.
Side effects worth expecting
Sleepiness is the usual one, often with a dry mouth, nose and throat. Dizziness, nausea, headache and muscle weakness also turn up, and children can become restless or excited instead of sleepy. Stop the tablets if you cannot pass urine, or if your vision blurs or changes. Appetite often increases while you take cyproheptadine, and some people gain weight over weeks of use; the drug has been used deliberately to encourage eating.
Alcohol, sedatives and the pack
Alcohol and other sedating medicines, such as sleeping tablets, anxiety medicines and strong painkillers, add to the drowsiness and dizziness. Avoid driving or using machinery until you know how a dose treats you. Keep the tablets in the pack they came in, away from heat and damp and out of reach of children. Packs hold 30 to 360 of the 4mg tablets.
