1. What Opilon is and what it is used for

Opilon tablets contain the active ingredient moxisylyte hydrochloride (equivalent to 40 mg of moxisylyte).

Opilon is a “vasodilator” which works by widening the blood vessels and improving blood circulation.

Opilon is used for the short-term control of Raynaud’s Phenomenon in adults. This is a condition where the fingers and toes become discoloured and is triggered by responses to cold, or emotional distress. Opilon helps by improving blood circulation to the extremities.

2. What you need to know before you take Opilon

Other medicines and Opilon

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

In particular, tell your doctor or pharmacist if you are taking any of the following medicines, because Opilon may interact with them:

  • antihypertensives (to reduce high blood pressure): Opilon may increase their effect.
  • antidiabetic medicines (to treat diabetes): your insulin requirement may be reduced.
