Hello,

Thank you for asking your query at DoctorSpring.

The chance for you to get cold sore from this kind of exposure is negligibly small.I would call it practical zero.

HSV1 typically spreads via a direct contact. Actually just direct contact is not enough for a transmission. Repeated direct contact exposure for upto 3 months is needed for transmissions.(as proven from studies among HSV positive and NON HSV individuals). If you are really unlucky you can get exposed to cold sore (HSV1) from saliva. But again you should understand that you get the same chance of contracting a lot infectious disease from anyone whom you are interacting with.

Add to that fact that almost 50# adults already have HSV1 virus exposure by teenage + 10-20 percent will never manifest HSV infection + 1/3 times HSV infection wont get transmitted by contact.

Putting all this together, it is unlikely that you are at any risk

Hope this helps

Hello,

No there are no such protective eye drops. But it is not really required. You can use some sort of goggles if this is really a concern.

Thank you

Sure,

First of all Codeine is not an recommended medication for Migraine.
It might give pain relief, but there are better and safer alternatives like Triptans / Ergotamine etc. You should consider those.

Now the dose of Codeine. There is no single 'optimal dose'.

15-60 mg every 4 hours as needed; maximum total daily dose: 360 mg/day is the maximum recommended dose in day.
Since you are already on 120 mg the maximum suggested would be 120mg two tablets per day. But remember this will increase your opioid threshold.
