Follistim Description
Follistim is cartridge intended for an injection
Follistim is a gonadotrophin hormone cartridge that is intended for injection. It consists of highly purified rFSH (recombinant follicle stimulating hormone) with neither urinary proteins nor LH (lutenising hormone). Follistim is also known as Puregon or Follitropin Beta. Since it is very pure, Follistim (Puregon) is used to treat fertility problems in combination with Pregnyl (hCG - human chorionic gonadotrophin) to stimulate the ovaries in women. It can also be used alone to stimulate sperm production in men.
Follistim - What's Included
The box of Follistim (Puregon) contains Follistim cartridges. In order to administer the Follistim cartridges you need to purchase a Follistim pen, also sold on IVFPharmacy. This medication is supplied in 3 cartridge sizes: 300/600/900 iu.
The Difference Between US and European Follistim
Follistim (Puregon) on IVFPharmacy is made by Organon Pharmaceuticals. It is a brand medication, not generic. The drug composition is exactly the same as Follistim in the US but the packaging may vary slightly. Here's how:
US packaging:
A box of Follistim in the U.S contains a Follistim pen so there is no need to purchase one separately.
European packaging:
Follistim is also known as Puregon so the name of the package may differ from what you are used to in the U.S. Even though the brand name is different the medication is actually manufactured by the same manufacturer as in the U.S. 
Follistim (Puregon) in Europe is sold without the pen which needs to be bought in addition to the meds. Microneedles are included with the cartridges. Follistim is marked for use within 90 days when removed from refrigeration for international shipping. 
  • Follistim can be substituted with Gonal F (if allowed on RX). Gonal F is sent with express shipping and is generally delivered more quickly than Follistim.
  • Follistim is commonly ordered with: Menopur, Cetrotide, Crinone, Endometrin
Follistim Uses and Side Effects
Follistim Uses & Indications:
Follistim is used as a fertility treatment in men and women. In women it stimulates egg production in healthy ovaries. In men it stimulates sperm production. Follistim is essentially a FSH hormone. While it can be used on it’s own, it is often used as part of a fertility drug program and in combination with HCG drugs. FSH means follicle stimulating hormone. HCG means human chorionic gonadotrophin.
Follistim Side Effects:
Common Follistim side effects include: Headache, stomach pain, bloating, redness/pain at the injection site, breast tenderness/pain or dizziness.
Serious side effects that require medical attention include: Flu-like symptoms including fever, chills, muscle aches and tiredness, swelling of ankles/hands/feet or bleeding from the vagina. Consult with your doctor immediately if you feel weakness on one side of the body, slurred speech, vision changes, sudden severe headache, pain/swelling of the calf muscles, chest pain, rapid breathing or signs of OHSS.
Ovarian Hyperstimulation Syndrome (OHSS) can cause fluid build up in the stomach, chest, and heart area. Symptoms of OHSS include severe pain/swelling in the pelvic region, severe nausea/vomiting, sudden/rapid weight gain, or change in the amount of urine. If you develop a rash, itching/swelling (especially of the face/tongue/throat), severe dizziness or have trouble breathing it might be caused by a severe allergic reaction, seek urgent medical attention.
