For Bacterial Vaginosis "This drug tinidazole was absolutely awful, and I will never take it again. I had to take a dose of 4 pills at 500 mg each for 2 days. The side effects I had were a headache, my fatigue was even worse, the most disgusting taste in my mouth, and after my second dose, I woke up sweating, vomiting, and had diarrhea. It better had done the job of getting rid of the BV because this was the worst experience I have ever had with any drug. I'll give it a 2 because I think it did work, but the side effects are NOT worth it."

For Trichomoniasis "I took tinidazole (4 pills at once = 2 g) on March 16th, 2021. I took it because I was diagnosed with Bacterial Vaginosis as well as Trichomoniasis. I also had yeast (yes, I know so much going on). I took Monistat 3 a day to clear up the yeast. I took this as soon as I got done eating, so my stomach was nice and full. I felt fine after taking this medication the first day. The next day, March 17, 2021, there were very mild symptoms. The symptoms were so mild that I still went about my day without being bothered. During that evening, I had some diarrhea and felt nauseated with very little appetite. But it wasn't to the point of overbearing... my nausea wasn't that bad, it was mild. My appetite seems to be the only thing that really did something, but I still ate. Oh, and urine was dark, and all I drink is water (but taking this med does give you dark urine). On March 18th, symptoms are nonexistent, no smell, no heavy discharge, and side effect symptoms from medication are gone."

For Giardiasis "I was terrified to take this tinidazole for giardia. I took 1 pill to see what it would do in the height of my infection. It did give me diarrhea. Later (a week), I took the correct dose, all 4 in a day but a couple of hours apart. It wasn't bad. I did get a metallic taste, my stomach rumbled, but other than that, I was fine. I did make sure to eat a big meal first, take lots of water, and avoid anything with alcohol. Unfortunately, after 3 weeks, I believe the giardia is back. Not sure if because I had so bad, or it's something else? These reviews really scare people. Unfortunately, everyone is different. I am sensitive and was able to take this, however, I would not recommend if your stomach is in a horrible state. When I took the first pill, I couldn’t even eat a piece of bread without pain. Try not to take it when your stomach is completely out of whack. Get yourself a bit together first. This is a strong medicine on your stomach. Have some graham crackers on hand and kefir to keep coating your tummy. Good luck."

For Bacterial Vaginosis "So I read all the bad reviews before taking this, so I'm writing this in case it'll help someone else. To avoid any vomiting, I ate food, took a Bonine (tablet to stop nausea), ate some more food, then took 2 of the antibiotics and chugged a 16.9 oz bottle of water. I did this for the second set of two pills I took a few hours later. I had to take 4 pills daily for 2 days. This didn't help avoid the chills, headache, or the metallic taste, but I didn't vomit or have diarrhea. Not sure if it'll work out the same for you, but I want to share in case it does. Not entirely sure if it worked for me in regards to my condition."

For Bacterial Vaginosis "Well, today is Wednesday. I just took 4 pills, my 1st day. So, I think I got BV because of damp swimsuits while vacationing in Cancun. We did snorkeling, swimming at the pool, and cave swimming 4 days in a row. I practically lived in swimsuits. Anyway, on top of this, I also ate something, and I've had vomiting, stomach cramps, and diarrhea. This pill takes care of it all together. As I'm typing this, I can taste the metallic taste, but it's not too bad. I just wouldn't handle more puking or diarrhea. I'll let y'all know in 3 days."

For Trichomoniasis "I was prescribed two 500 mg pills to get rid of trich. I went to the doctor at 1:30 and left about 3. Maybe an hour or two later, I had horrible diarrhea! My cycle came on a couple of days later, and now the scent is back with a discharge. Did the diarrhea have an effect on the pill?"

Tinidazole for Giardiasis "I was (incorrectly) diagnosed with giardia and took Tindamax. I had a horrible reaction with nausea and diarrhea. This went on, and I ended up hospitalized for days. The bad taste in your mouth lasts a LONG time after you take the medication. It takes a long time to clear your system, as this is a long-acting medication. The reaction I had sounds like what is supposed to happen if you drink alcohol while taking it. I am certain I did not drink alcohol, but I got this ill anyway. The real bummer is that after I took it, I was told the lab made a mistake and I did not actually have giardia!!"

Tinidazole for Bacterial Vaginosis "Well, I can say the taste, the headaches, the cramps, the fast heartbeat, which caused my severe anxiety to go bananas, is due to this med. Day 5 now, I feel like it's back. Ugh!!!! I don't get it. My muscles hurt too. It's making my pain from open surgery worse! Oh, and a loose stool an hour after taking it."
