Interactions between your drugs

Moderate

apomorphine safinamide

Applies to: APO-Go (apomorphine), safinamide

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Central nervous system (CNS) depressant effects may be additively or synergistically increased in patients using apomorphine in combination with other drugs that can also cause these effects. Apomorphine alone has been frequently associated with somnolence and dizziness. Patients may suddenly fall asleep during activities of daily living.

MANAGEMENT: The use of other sedating drugs should generally be avoided during apomorphine treatment. Patients prescribed these agents concurrently should be monitored for potentially excessive or prolonged CNS depression, especially if they are elderly or debilitated. Ambulatory patients should be made aware of the possibility of additive CNS effects (e.g., drowsiness, dizziness, lightheadedness, confusion) and counseled to avoid activities requiring mental alertness until they know how these agents affect them. If patients experience increased episodes of falling asleep during normal daily activities, they should avoid driving and other potentially hazardous activities until they have contacted their physician.

Drug and food interactions

Moderate

apomorphine food

Applies to: APO-Go (apomorphine)

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Alcohol and apomorphine may have additive hypotensive and sedative effects. Coadministration of 0.6 or 0.3 g/kg of ethanol with apomorphine in healthy subjects resulted in greater decreases in blood pressure compared to apomorphine alone. The mean largest decrease (the mean of each subject's largest drop in blood pressure measured within 6 hours after apomorphine administration) in standing systolic and diastolic blood pressure was 6.7 and 8.4 mmHg, respectively, with apomorphine alone. When coadministered with 0.6 g/kg of ethanol (equivalent to approximately 3 standardized alcohol-containing beverages), the mean largest decrease in standing systolic and diastolic blood pressure was 11.3 and 12.6 mmHg, respectively (standing systolic and diastolic blood pressure decreased by as much as 61 and 51 mmHg, respectively, in this group). When coadministered with 0.3 g/kg of ethanol, the mean largest decrease in standing systolic and diastolic blood pressure was 8.4 and 7.1 mmHg, respectively.

MANAGEMENT: Patients should be advised to avoid consumption of alcohol during apomorphine treatment.

Moderate

safinamide food

Applies to: safinamide

Safinamide may be taken with or without food. While there is no need to strictly avoid most foods and beverages that contain tyramine (usually aged, fermented, cured, smoked, or pickled foods such as air-dried and fermented meats or fish, aged cheeses, most soybean products, yeast extracts, red wine, beer, and sauerkraut) during treatment with safinamide, certain foods such as some of the aged cheeses (for example, Boursault, Liederkrantz, Mycella, and Stilton) and pickled herring may contain very high amounts of tyramine and should generally be avoided if possible. Consumption of very high levels of tyramine (greater than 150 mg) while on safinamide treatment may lead to dangerous increases in your blood pressure, a condition known as hypertensive crisis. Talk to your doctor or pharmacist if you are uncertain about what foods, if any, to avoid. You should seek immediate medical attention if you experience sudden and severe headache, blurred vision, confusion, seizures, chest pain, nausea or vomiting, sudden numbness or weakness (especially on one side of the body), speech difficulties, fever, sweating, lightheadedness, and/or fainting during treatment with safinamide, as these may be signs and symptoms of a hypertensive crisis. Do not take larger doses or use the medication more frequently than prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
