Hi! Yesterday, I went to see my dentist for tooth extraction and currently taking antibiotics and mefenamic acid for 7 days. Next week, on Wednesday, I'm going to undergo blood testing, urinalysis and fecalysis. Question, is it okay to undergo these procedures even though I'm taking medicines? I'm so busy and Wednesday is the only day I'm available. Plus, clinics are closed on Christmas holiday. Please help me. Thanks!
