Can i give my 5 yr old an antihistamine before eating out for fear that might eat foods not allowed for him because he has allergies
Benadryl (diphenhydramine) or Epipen: Which antihistamine are you planning to give? And do you know what they're allergic too? Most times you only give antihistamines if you know your going to be exposed to an allergen. If you feel you must give one, do not give Benadryl (diphenhydramine) until age 6. The other problem with medicating children is that adults tend to give to much. My advice is to get a prescription for Epipen to use for emergencies... ...Read more
Im a 23 year old male and antihistamines completely knock me out to the point where its hard to wakeup. Im on the smaller side so could that effect it?
Different med: Most antihistamines are based on age rather than weight. Also, first generation (old) antihistamines commonly cause drowsiness. Most people do not have drowsiness with the new generation antihistamines such as claritin, (loratadine) zyrtec, allegra. However, for whatever reason, some people are sensitive to usual doses.

But before using any antihistamine in a tiny baby, check with your doctor. Don't use antihistamines for colds. They make secretions thick and increase sinus infection. ...Read more
Fatigue: Benadryl (diphenhydramine) can cause fatigue from overuse in most people. Claritin does not usually have this issue. Antihistamines also can cause urinary retention due to their anticholinergic effects. As with any medication, they should only be taken if their benefits outweigh their risk for the problem being treated. If someone has significant allergy symptoms, taking a non-sedating antihistamine is helpful. ...Read more
None: None that I am aware of. I am not sure he has an allergy either at 2 weeks of age. He may instead just have a cold. I would just use a gentle nasal saline spray and use a suction device like Nosefrida. My wife uses it on our 3 year-old. Use a cool mist humidifier too. And, have him see his pediatrician if no improvement. Most drugs used in infants starts at 2 years of age. ...Read moreSee 2 more doctor answers
