Can you take arnica tablets and an antihistamine together at the same time before getting lip filler/lip injections?

Excellent question. Patients often find that simple steps they take before a procedure, such as taking arnica, can make a difference in the recovery process. However, the most important consideration is the expertise and experience of your injector. Plastic surgeons that have undergone appropriate training and perform injections daily usually have patients that experience minimal side effects. I always recommend icing after lip injections, to manage possible swelling and soreness after the procedure. This is likely to be just as – if not more – effective than antihistamines. However, talk to your surgeon about their recommendations for preparing for your treatment. Good luck!

Hello, arnica is highly effective to reduce bruising and swelling. I would recommend pre treating for four to five days before your injection and continuing for a few days afterward. You can also take antihistamines simultaneously. 

Hello and thank you for your question.

The combination Arnica tablets and antihistamines by itself helps with the late vascular inflammation reaction at 30-180 minutes post procedure.
FDA labels oral Arnica as unsafe because of its potential liver toxicity at high doses.
To be very cautious topical Arnica and oral antihistaminics are perfectly OK peri procedure.
For those interested, I attached a link to a study on Arnica anti inflammatory effects.
