Pharmacist tips for Loratadine (Claritin)

pharmacist
  • You can take loratadine (Claritin) only when you need it for occasional allergies. But if you have allergy symptoms every day, take it daily according to the manufacturer's directions. This can help you get the most relief from the allergy medication.
  • You can take loratadine (Claritin) at any time of day. It usually starts working within a few hours. If you know when your allergies are the worst during the day, you can try to plan to take it before that time.
  • You can take loratadine (Claritin) with or without food. If it hurts your stomach, try taking it with food next time to see if that helps.
  • If you have kidney or liver problems, ask a healthcare professional before taking loratadine (Claritin). They can make sure it's safe for you to take. This is because you might have a higher risk of side effects from the medication.
  • For loratadine (Claritin) regular tablets: Swallow the regular tablet whole with water. If you have trouble swallowing pills, try a different form of the medication that might be easier to take. Ask a pharmacist if you need help choosing one.
  • For loratadine (Claritin) chewable tablets: Chew or crush the tablet before swallowing. Don't swallow it whole. You don't need to eat or drink anything when you take the medication.
  • For loratadine (Claritin RediTab) orally disintegrating tablets: Place the tablet on your tongue and let it dissolve in your mouth. You can take the tablet with or without water.
  • For the loratadine (Claritin) liquid: Use a medication dose cup or an oral syringe to measure out the dose. Ask the pharmacy if there isn't one included in the medication box or if you need extras. Don't use kitchen spoons because they might not be accurate and using them might cause you to take the wrong dose.
  • Loratadine (Claritin) might make you feel a little sleepy. Don't drive until you know how this medication affects you.
  • Try to drink less alcohol or avoid it while taking loratadine (Claritin). Alcohol can make side effects, like sleepiness or dizziness, stronger. Talk to a healthcare professional about how to take this medication safely if you drink alcohol.
  • Don't start any new medications while taking loratadine (Claritin) without talking to a healthcare professional or pharmacist first. This is very important with other antihistamines. Taking more than one antihistamine can raise the risk of an overdose. This can lead to serious side effects, like seizures, seeing or hearing things that aren't real, or even death.
  • If you think you or someone else has taken too much loratadine (Claritin), get medical help right away or call Poison Control at 1-800-222-1222.

Sleepiness

  • Risk factors: Drinking alcohol while taking loratadine (Claritin) | Taking other medications that cause sleepiness

Loratadine (Claritin) might make you sleepy. This can make it harder to focus, think, or react quickly. You're more likely to have this side effect if you drink alcohol while taking this medication.
