Of course, there's no medication or at-home solution that may come without side effects. Knowing the risk before buying some cold-pressed flaxseed oil for your eye treatment is important.
Per Healthline, there isn't enough scientific data definitively linking flaxseed oil with dry eye relief. However, should you use flaxseed oil to alleviate dry eyes, be wary of interactions with other prescription and OTC medications, as it may render them ineffective. Flaxseed oil may also adversely lower blood sugar and may also decrease blood pressure, which can be dangerous. So people who take blood sugar medication or who have low blood pressure may want to avoid taking flaxseed oil.
It's important to consult with your doctor before taking any new medication or treatment for a condition. If you already have medical conditions like diabetes or underactive thyroid, it's best you get their advice first before consuming flaxseed oil (via Verywell Health).
