Antihistamines are generally safe for most patients. Older antihistamines, such as diphenhydramine, are not recommended for individuals who have prostate problems or glaucoma. Older adults who are prone to falling and sedation should also avoid using diphenhydramine.

Decongestants are not recommended for individuals with high blood pressure. That’s because they relieve nasal congestion by narrowing blood vessels and reducing swelling in the nose. This process can affect other blood vessels as well, which can increase blood pressure.

If you are pregnant or breastfeeding, consult a healthcare professional before using any allergy medications.

Besides that, most people can take OTC allergy medications with no problems.

The answer to this question depends on your symptoms and the side effects that you want to avoid.

Cetirizine, loratadine and fexofenadine have similar efficacy and side effects. The effectiveness of cetirizine and fexofenadine, however, can wear off over time in some people. Cetirizine and fexofenadine both cause less sedation compared to diphenhydramine, but loratadine generally causes the least amount of daytime drowsiness.

Diphenhydramine, on the other hand, is considered to be overall stronger and better than other antihistamines at treating hives and other allergic symptoms. The downside to this option is that diphenhydramine causes drowsiness (more in some people than others). It is powerful when it comes to addressing symptoms, but we don’t recommend taking it during the day if you have stuff you need to get done. Also, while most allergy medicatations are taken once or twice a day, diphenhydramine is generally taken every four to six hours.

Antihistamines are generally safe to be taken daily for a short period of time. However, it is not recommended that you take them every day in the long-term, unless instructed to do so by your healthcare provider.

If your allergies tend to bother you for long periods of time, we recommend that you investigate what triggers them. The allergen might be something that you can avoid having contact with, such as a specific type of tree or pet. Working with an allergist to develop a treatment plan may be the most effective option in the long-run.

Some allergy medications are safe to be combined.

In general, you can use an over-the-counter antihistamine with a decongestant (like phenylephrine). That is, if you have no conflicting medical conditions. Always speak with your doctor prior to taking any nasal decongestants if you have pre-existing chronic conditions.

However, it is not always safe to take two oral antihistamine medications in one day. For example, you don’t want to take a cetirizine pill in the morning and a loratadine pill in the afternoon. Check with your friendly neighborhood pharmacist for questions about antihistamine dosing and side effects.

Even though some allergic reactions are serious, the majority of allergies are mild and some symptoms may resemble that of a cold.

Some common symptoms include:

  1. Sneezing

  2. Itchy, runny, or blocked nose

  3. Watery, red, or itchy eyes

  4. Itchiness, rash, or hives

  5. Shortness of breath and cough

If you feel a couple of these symptoms, especially itchiness, for extended periods of time, you likely have allergies — not a cold.
