Symptoms: joint pain, blisters on tongue, low blood pressure, dizziness, loss of vision. I started Levaquin 750 mg orally 11 days ago for diverticulitis, along with Flagyl. I had taken Levaquin in the past for this same condition without any side effects. I am also on Benicar 25 mg for high blood pressure. This time after spending $106 dollars AFTER insurance, I started having problems with dizziness where I would lose my vision for a few seconds every time I stood up from a sitting position, or sat up from laying down. My arms and legs felt very heavy and I was exhausted and felt like I could hardly walk. Since I had taken this drug before without complications, it didn't occur to me that this might be a side effect of the Levaquin. My doctor recommended I stop taking the Flagyl, which I did. Nothing improved. After several days of this I finally went to an after hours clinic and found that my blood pressure was 90/50. The nurse told me to stop taking my blood pressure med for a few days, that maybe there was a reaction. (She stated she had never heard of blood pressure being affected by an antibiotic). I stopped taking my blood pressure medication and it came up to normal within about 36 hours. Approximately 4 days ago my tongue broke out with little blisters all over, top and bottom and my lips are cracking. Yesterday my joints started aching and I feel like I'm 75 every time I take a step. (I'm 46) I took my last Levaquin yesterday and I still have the blisters and the joint pain is worse. This morning my blood pressure was back to my normal "mild high" range of about 130/83. I took my blood pressure med and it came back down to what is normal for me, 122/77. I haven't done anything different (meds, food, products, etc.) that should be causing these blisters, and I don't feel sick other than the joint pain, so I'm assuming these are side effects related to the Levaquin. I'm hoping they will clear up now that I'm done with the medication. I find it interesting that I spoke with two different pharmacists and two different physicians and none of them indicated there might be contra-indications with Levaquin and my blood pressure med. The good news is that the diverticulitis seems to be gone!
