colds and meds

I am a 71 yr old female, have a history of blood clots, 2 to be exact within the past 4 years in my right leg, have been permanently placed on Warferin to keep my blood thinned, also on Sotolol after a 12 yr history of bouts with Sinus Tachacardia.
This has kept my heart under control as far as bouts with rapid heart episodes starting out of the blue.
My problem is I started the new year with a cough that developed into congestion, sore throat and all that goes with a bad cold. I am leary of over the counter cough or cold meds due to what is going on with me health wise. Dr prescribed Amoxicillin 875 mg and Promethazine Codeine syrup, thinking the antibiotic is not really going to fight a cold virus after reading up on this? After my last INR, my blood reading was 1.2 and am normally between 2 and 3, which is where they want me to be. Hmmm...is there something else that might work for me now and in any future bouts with a cold virus?
I stopped the meds and am taking fresh lemon, cinnamon and honey mixture with hot water, also plenty of hot tea with lemon and honey, and drinking more water.
Question is, is there an over the counter cough med that would not interfere with my health situation? Thanks!

Welcome to the forum, maybella1213.

Why did you stop the medicine your doctor prescribed? Did the cold, if it was that, go away? Lemon and honey aren't going cure an infection, just maybe feel good. The codeine promethazine was for the cough. Did your cardiologist say to stop that? There isn't anything that cures a cold. But if the condition goes on for a time, it's more than a cold, and that's why the doctor would prescribe an antibiotic.

You mentioned getting tachycardia out of the blue. I get it too, but it's not out of the blue. I have a specific sensitivity to a chemical that brings it on. I didn't have it all my life; it's acquired.

My sensitivity happens to be to sulfites, but others have reactions to different chemicals. Sulfites are preservatives in things like dried fruits, bleaching agents in things like boxed or canned potatoes, and are used in the processing of corn into corn starch. And that's just for a start. They're natural in a few foods.

To find out if one has a sensitivity, my allergist has people keep a food diary/log/journal. We write down everything we eat or drink, all medications, and the time. Then we also write down any reactions, for me the tachycardia, especially within 2 hours. People who get migraines have to look back as far as 2 days to find the trigger food.

If you get a list of possible trigger foods, you then google the list and "food allergies." That's how I found my whole list and what is in those foods.

I don't have any tachycardia now, as long as I don't consume sulfites above my tolerance level. It's not like a peanut allergy. It's called a sensitivity now.

There are loads of threads on food sensitivities and sulfites. Just put some words in the search box at the top of the page.
