I accidentally took Allegra 120mg once in the afternoon and then again at night. Should I be worried about that? Are there any serious side effects from taking it twice like this?

If you mistakenly take two doses of Allegra 120mg in a day, there may be an increased risk of side effects such as drowsiness, dry mouth, and headache. It is important to stick to the recommended dosage of one tablet (120mg) per day to avoid potential adverse effects. If you have taken two doses in a day, monitor yourself for any unusual symptoms and consider skipping the next dose to prevent further complications.

I'm really concerned about my COVID diagnosis and the medication my doctor prescribed. They gave me Fabiflu and told me to take 800 mg twice a day, but on the first day, I had to take 1800 mg twice. I'm a bit confused about how long I should wait between each dose. Can you help clarify this for me?
