Hi doctor,

I am 32 years now. Last Monday got LASIK for my eyes and in recovery phase this week. I had cold before that which has increased and continuing till now. I have throat irritation and slight nose block for which I took Otrivin at night for 2 days but still not much improvement. What tablets shall I take? I also have some mouth ulcer for past 2 days. What tablets shall I take for that? LASIK doctor had told no restriction in food or medical practices. After your suggestion will also check with him once if you recommend so. Thank you.



Welcome to I have read through your query in detail. Please find my observations below.

  • If I was your treating physician, I would recommend you over-the-counter cough syrups like Syrup Grilinctus (contains Dextromethorphan hydrobromide, Chlorpheniramine maleate, Guaifenesin and Ammonium chloride). Take one teaspoon syrup of about 5 ml three times a day for one week.
  • Please do warm water gargle twice daily. It is relatively safe and has no addictive ingredients. It will give you some symptomatic relief.
  • For mouth ulcer you can use Zytee-RB gel (combination of Choline salicylate and Benzalkonium chloride) to be applied over the ulcer in the mouth.

Hi doctor,

I have tried Grilinctus yesterday twice, at noon and night, but looks like it is triggering more dry cough now. This is more than it was before. Can I still continue? Or do we have any other alternative? I took vitamin B complex tablet and found my mouth ulcer got cured. LASIK doctor told I could take normal medication as I have crossed 1 week and my eye healing is normal.



Welcome back to

Thanks for writing back with an update. Nice to know your mouth ulcer has healed and please continue taking vitamin.

  • It is early to judge that Grilinctus is causing your dry cough. However, you can stop Grilinctus and take Cetirizine tablet 10 mg at night for a week. This will give you to get relief from dry cough.
  • If Cetirizine is not working for your dry cough then you can take Fexofenadine which is Allegra 120 mg once daily for a week.
  • It looks like you are having symptoms from cold weather. Please take precautions for cold and avoid dust and pollution.
  • Please continue to do warm water gargle twice daily.
