I am taking a cough medicine called Tussionex. I have noticed that it (among others) has a warning label for people with glaucoma. I have been monitored with intraocular hypertension for about a year now. Could this medicine hurt my eyesight?

Thanks for your advice.

Some medicines have anticholinergic effects, and this can worsen some types of glaucoma.

You should not take any medication with this warning until you clear it with your ophthalmologist.
