Hi doctors. please can i get an eye drop over the counter for red shot eyes i got due to coughing while sleeping ? i woke up about 2 hours later to a red eye 2days. no pain, no itchiness, nothing, just red?

Most likely a subconjunctival hemorrhage secondary to the forceful coughing. If this is the case, it may look bad but is relatively benign and will fade over a few days. Eye drops are not needed. If additional issues develop, see eye specialist.

No eye drops necessary. You may use nonprescription artificial tear drops. It is likely some viral conjunctivitis from a common cold and will pass. Is it one eye or both? A picture would be helpful. A cold or warm compress may give you some relief. The redness will likely pass soon.
