› Avonex (Interferon Beta-1A) can cause serious liver injury with the risk increasing during the first 6 months after you start. You'll need to have your liver enzymes tested at 1, 3, and 6 months. If liver enzymes are significantly elevated and you have appetite/weight loss, stomach discomfort, vomiting, and notice dark urine, yellowing of skin/eyes, change in stool color, and skin rash, you should stop taking Avonex (Interferon Beta-1A) until your doctor decides if it's safe to re-start.

Upsides and benefits
› One of the main treatments for relapsing MS that has been around for many years.
› Injections are given weekly, and not daily like other MS medications.
› Helps reduce the frequency of MS relapse episodes.
› Flu-like reactions are the most common side effects and usually go away with continued treatment or can be avoided by using over-the-counter pain and fever-reducing medicines before the injection (like acetaminophen or ibuprofen).
› Gilenya (Fingolimod) is the first once-daily pill you can take for relapsing forms of multiple sclerosis (MS).
› Studies show it lowers relapse rates better than placebo and Avonex, and it delays the progression of physical disabilites better than placebo.
› Gilenya also reduced the number of new MS lesions better than Avonex.
Downsides and risks
› Injection site reactions are common, ranging from localized pain, redness, and swelling to severe skin dryness.
› Flu-like symptoms are common after interferon injections.
› It's not clear what type of problems occur if taken during pregnancy.
› Blood testing is required before and during use of Avonex (Interferon Beta-1A).
› May not be as effective as other interferons.
› Taking more than the 0.5 mg dose won't give more benefits, but will only cause more side effects.
› Gilenya can remain in your blood for up to 2 months after you stop taking it. Your immune response won't work as well during this time.
› Not the best choice if you've had a heart attack, stroke, or have been in the hospital for heart failure in the past 6 months. The risk of serious heart rate effects is higher when taken with certain drugs (methadone, erythromycin, citalopram, ketoconazole) or if you have low potassium or magnesium.
› If you have to re-start Gilenya after stopping it for 2 weeks or more, you'll have to take your first dose at your doctor's office again.
› If you didn't get chicken pox and never had a vaccination, you'll need to be vaccinated and wait one month before starting Gilenya.
Tips from our pharmacists for people taking the medication
› Inject yourself once a week in your muscle (you need to go deeper than the fat layer between your skin and muscle).
› Refrigerate the powder and pre-filled syringes and pens.
› Don't shake the medicine once it is taken out of the refrigerator or mixed.
› If using the pre-filled syringes, the tiny air bubbles won't hurt you.
› Avonex (Interferon Beta-1A) can cause flu-like symptoms (headache, fever, muscle pain) right after injections, lasting minutes or hours.
› Flu-like reactions usually go away with repeated treatments. Taking acetaminophen or ibuprofen 45 minutes before the injection can reduce the uncomfortable feeling.
› Take one capsule daily with or without food.
› It's very important you read the Gilenya Medication Guide. Don't change your dose or stop the medicine without asking your doctor.
› You'll need to be watched for at least 6 hours in a doctor's office after taking your first dose because it can cause serious heart rate and blood pressure problems.
› Gilenya increases your risk of infections. Get blood tests 6 months before starting treatment.
› Use effective birth control or plan to stop Gilenya 2 months before getting pregnant. If you do become pregnant while on Gilenya (Fingolimod), you'll need to enroll in the Gilenya pregnancy registry.
› Tell your doctor if you've had any vaccines recently. Don't get any live vaccines while taking Gilenya.
› Your doctor will monitor your eyes, lungs, and liver for up to 2 months after stopping Gilenya.
