What is Safinamide used for?
Safinamide is used with another medication (levodopa/carbidopa) to treat symptoms of Parkinson’s disease. It can help improve symptoms such as shakiness, stiffness, and difficulty moving. It can also help reduce the amount of “off” time (periods of slow movement or stiffness).
Safinamide belongs to a class of drugs known as MAO inhibitors. It works by increasing the levels of certain natural substances in the brain (such as dopamine). Parkinson’s disease is thought to be caused by too little dopamine in the brain.
How should I take Safinamide?
Take this medication by mouth with or without food as directed by your doctor, usually once daily.
The dosage is based on your medical condition and response to treatment. Do not increase your dose or take it more often than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.
Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.
Do not stop taking this medication without consulting your doctor. Some conditions may become worse when this drug is suddenly stopped. Your dose may need to be gradually decreased.
A very serious high blood pressure reaction may rarely occur if you eat a large amount of tyramine while taking safinamide and for 2 weeks after you stop it. Avoid foods that are high in tyramine, like aged cheeses (such as Stilton cheese). Consult your doctor or dietician about which foods you should avoid and if you do not feel well after eating or drinking certain foods while taking this medication. Tell your doctor if this medication stops working well or if your condition gets worse.
How do I store Safinamide?

There may be different brands of Safinamide that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.

Safinamide is pregnancy risk category C according to the US Food and Drug Administration (FDA).
FDA pregnancy risk category reference below:

What side effects can occur from Safinamide?
Dizziness or drowsiness may occur. If either of these effects lasts or gets worse, tell your doctor or pharmacist promptly.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position, especially when you first start taking safinamide.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including: fainting, loss of balance, mental/mood changes (such as anxiety, agitation, hallucinations), worsening muscle stiffness/twitching/uncontrollable movements, unusual strong urges (such as increased gambling, increased sexual urges).
Some people taking safinamide have fallen asleep suddenly during their usual daily activities (such as talking on the phone, driving). In some cases, sleep occurred without any feelings of drowsiness beforehand. This sleep effect may occur anytime during treatment with safinamide even if you have used this medication for a long time. If you experience increased sleepiness or fall asleep during the day, do not drive or take part in other possibly dangerous activities until you have discussed this effect with your doctor. Your risk of this sleep effect is increased by using alcohol or other medications that can make you drowsy. This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take. Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.
This drug may rarely cause an attack of extremely high blood pressure (hypertensive crisis), which may be fatal. Many drug and food interactions can increase this risk. Get medical help right away if any of these serious side effects occur: severe headache, fast/slow/irregular/pounding heartbeat, chest pain, neck stiffness/soreness, severe nausea/vomiting, sweating/clammy skin (sometimes with fever), widened pupils, vision changes (such as double/blurred vision), sudden sensitivity to light (photophobia).
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
Not everyone experiences these side effects. There may be some side effects not listed above. If you have any concerns about a side-effect, please consult your doctor or pharmacist.
What drugs may interact with Safinamide?
Some products that may interact with this drug are: apraclonidine, bupropion, buspirone, carbamazepine, diet pills/appetite suppressants (such as diethylpropion), deutetrabenazine, dextromethorphan, methyldopa, certain supplements (such as tryptophan, tyramine), tetrabenazine, certain “triptans” used to treat migraine headaches (such as rizatriptan, sumatriptan, zolmitriptan), valbenazine.
The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Examples include street drugs such as MDMA/”ecstasy,” St. John’s wort, certain antidepressants (including trazodone, SSRIs such as fluoxetine/paroxetine, SNRIs such as duloxetine/venlafaxine, tricyclics such as amitriptyline/doxepin), drugs for attention deficit disorder (such as amphetamine, methylphenidate), cyclobenzaprine, certain narcotic medications (such as meperidine, methadone, propoxyphene, tramadol), among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.
Some products can interact with safinamide if you take them together, or even if you take them weeks before or after taking safinamide. Tell your doctor or pharmacist if you take anything in the list of products that may interact with this drug, or any of the products that increase serotonin, within 2 weeks before or after taking safinamide. Also tell them if you have taken fluoxetine within 5 weeks before starting safinamide. Ask your doctor how much time to wait between starting or stopping any of these drugs and starting safinamide.
Taking other MAO inhibitors with this medication may cause a serious (possibly fatal) drug interaction. Do not take any other MAO inhibitors (isocarboxazid, linezolid, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine) during treatment with this medication. Most MAO inhibitors should also not be taken for two weeks before and after treatment with this medication. Ask your doctor when to start or stop taking this medication.
Before using safinamide, report the use of drugs that may increase the risk of extremely high blood pressure (hypertensive crisis) when combined with safinamide, including herbal products (such as ephedra/ma Huang), allergy and cough-and-cold products (including decongestants such as phenylephrine/pseudoephedrine), and stimulants (such as amphetamines, ephedrine, epinephrine, phenylalanine). Talk to your doctor or pharmacist for more details.
Tell your doctor or pharmacist if you are taking other products that cause drowsiness such as opioid pain or cough relievers (such as codeine, hydrocodone), alcohol, marijuana, drugs for sleep or anxiety (such as alprazolam, lorazepam, zolpidem), muscle relaxants (such as carisoprodol), or antihistamines (such as cetirizine, diphenhydramine).
Safinamide may interact with other drugs that you are currently taking, which can change how your drug works or increase your risk for serious side effects. To avoid any potential drug interactions, you should keep a list of all the drugs you are using (including prescription drugs, nonprescription drugs and herbal products) and share it with your doctor and pharmacist. For your safety, do not start, stop, or change the dosage of any drugs without your doctor’s approval.
