What can I safely take over the counter?
I have High Blood Pressure (HTN) and I have a cold with congestion The effects decongestants have on the circulatory system make them dangerous for anyone who has an irregular heart rhythm, heart disease, glaucoma or high blood pressure. People who have these or related conditions should not take decongestants. Antihistamines don’t present a danger unless decongestants accompany them. Here is a list of a few commonly encountered medications located in your local pharmacy that are SAFE to take for individuals with high blood pressure fexofenadine (Allegra) loratadine (Claritin) cetirizine (Zyrtec) Coricidin Products diphenhydramine (Benadryl)
Caution!!! Combination Remedies DO NOT TAKE “decongestant”
Some cold remedies that contain antihistamines also contain a decongestant, such as phenylephrine or pseudoephedrine, which can have negative effects on your body if you have high blood pressure.
Considerations If you have high blood pressure and you’re not sure whether an antihistamine-containing product also contains a decongestant, don’t take the medication unless your doctor approves.
