"I was diagnosed with Trich & BV. Had to take 500 mg of 4 pills at once. I was scared after reading reviews. But I knew I had to take them to feel better. Ate before I took them. I felt hot & a little headache & had gas a little about an hour-2 after I took them. It ceased. Got tired & went to bed. Woke up with the metallic taste in my mouth. But nothing that is too bad or I can't handle. But today I feel better already. Even got my energy back. This was a lesson learned to use protection or don't have sex. This was the consequence of my stupidity. I can't blame anybody but myself."

Metronidazole "Was prescribed Flagyl for trich. I was skeptical and scared after reading the reviews because everyone made this medication seem terrible. This is my second time taking it and have not had one symptom either time. The first time I was prescribed a one-day dose of the four 500 mg pills. This time the 7-day dose. I’m on day 3 and feel better. The smell has gone away and so has the itch. I feel like a new woman. I would suggest taking this antibiotic on a full stomach or drink it with a glass of milk. I promise, it’s nowhere as bad as everyone makes it seem. My anxiety was through the roof after reading these reviews, but I womaned up and took it. Yes, the taste is absolutely terrible so please don’t roll it around on your tongue. I hope this helps ease someone else’s anxiety."

"Has anyone experienced having trich, which is resistant to metronidazole? First round took four 500mg of the meds, didn't work. Then was placed on two tablets 500mg for 7 days. It cleared up but as soon as I stopped the treatment, it came back, but not as bad. Then the last time I was placed on 2000mg for 7 days. Once again, took it away but as soon as I stopped, it came back, once again not as bad. I'm fed up with this and I'd like to know why my body is not clearing up. Has anyone had this issue and then found some relief? Please share."

"When I went into the ER, as I felt like ripping my insides out - down there. They diagnosed me with trichomoniasis. They gave me the one-time dose of 4 metronidazole 500mg pills. I will tell you swallowing them was terrible. I made the mistake of taking two at once first. They got stuck in my throat, I choked, and they came up dissolved and some went into my nose from inside my mouth. I had the most awful taste in my mouth. BUT immediately got something to eat after and so far (7 hours later) I have experienced not one side effect. My symptoms are not fully gone, I’m still itchy a bit down there, but the discharge has already subsided and the itching IS getting better. The doctor says allow 7 days for the medication to fully run its course. It’s an amazing medication that, in my experience, works far better and faster than any other antibiotic for any other diagnosis (not related to STIs). Quickest relief by far, and luckily so, because with this, relief is much needed. This girl, never ever wants to have sex again!"

"I had gotten diagnosed with trichomoniasis and they prescribed me this medication. The instructions were to take 4 pills at once (2000 mg). I thought that was absurd. Naturally paranoid with taking medication in the first place, I looked up the reviews and I did not see positive feedback. A lot of people said they had gotten sick or had heart palpitations, so my anxiety kicked in and it took me four days to finally suck it up and take it. Well, I took it before bed (it said dizziness may occur) and I went right to sleep. Woke up and felt nothing. Long story short, make sure you take it on a full stomach, take it before bed, and you should be fine. Don’t let reviews scare you because chances are those people didn’t follow the instructions. You'll be fine!"

"So I'm a female, I went in for an exam a month ago and my results came back positive for chlamydia. I was prescribed the 2 oral antibiotic tablets to take as one dosage. I didn't have symptoms, of course, beforehand and had some after taking the medicine, so I assume it was flushing out. So I went for my follow-up a few weeks later and had another exam. I had trich and BV, so I was prescribed the 4 pills of flagyl 500mg to take as one dosage, followed up by one dosage of diflucan 150 mg because I get yeast infections after taking antibiotics. I highly recommend taking the one dosage of four pills instead of the seven or two days. I ate before taking the medicine, however, later on in the day, I felt nauseous. I had a metallic taste in my mouth even when trying to drink water, so I just slept it off. However, the next day, I'm feeling great, no odor, no discharge, no nothing. And my results came back negative for any other STDs."

"Literally have taken every medication to clear trichomoniasis and it’s not going away, reading the comments I’m glad I’m not the only person going through this. Been trying to consider natural remedies and boosting my immune system to help fight trich off. You aren’t alone, ladies. I know it’s hard, but we will all get through this!"

"I have trich and I was put on the 4 pills at once of 500mg. I took it Thursday at noon. I was fine. I have to say the taste is not the best. Put it way back on your tongue, drink water, and swallow. Don't start smacking your tongue around, that's what makes you taste it. So I took it, went to work, and around 9 I got nauseous. It came and went. At 11:30 at night, I was very nauseous, I just went to sleep. The next day I noticed a lot less itch and burn. Absolutely no more nausea. Today, Saturday is day two, I feel good. Again, I'm not 100% clear because occasionally I feel a little itch, but I like this pill. Also, on day one on the pill, I had a one-time heavy discharge. It was like the infection came out. For those who ask, if you get the one-time four pills of 500mg, you must take all four at once. Trust me, you'll be okay."

"I was prescribed the 2000mg one-time dosage. Yes, the pills have a horrible taste, but I'd rather taste that than have the symptoms of trich! I've taken the same meds for BV before and usually end up pretty tired after about 2 hours or so. I took this about 12 hours after a night of heavy drinking. Have felt a little nauseous and had loose stools and a little headache. But it's been 3 hours since I've taken it, and the odor is weaker, and the discharge has dramatically decreased! Bye-bye trich and bye-bye cheating boyfriend that gave it to me!"

"I had to take a one-time dose of 4 500mg capsules. About two hours after taking the dose, I noticed I was feeling extremely tired. I was driving and decided to make my way home, so I wouldn't recommend driving. About 4 hours after, I felt a lot of nausea and general flu-like symptoms. I felt like I needed to sleep but was unable to fall asleep. These symptoms were not unbearable. It's been 3 days since I've taken this medication, and I still have minor side effects lingering. I have been having great sleep, random nausea, vivid dreams, and random bouts of fatigue. ALL of my symptoms from trichomoniasis have disappeared, so I would recommend this medication."

"So I was prescribed this medication for trich, as some of you are familiar with from reading previously. Well, I got great results from the medication, however, I did get vaginal irritation and itch with the discharge as a side effect. Honestly, having unprotected sex isn't a smart thing to do, but thankfully Trich is curable and the itch is also. Keep in mind, ladies, no matter how clean and good-looking he might appear, smelling good, he is probably not going to even know he is giving you more than a good five minutes of pleasure. It's 5 days of treatment that we carry now!!! Be smart!! Good luck."

"So I went to the doctor and they told me I had trich and a yeast infection with cervical cancer. They prescribed me metronidazole 500mg and told me to take 2x daily for 7 days but taking 18 wouldn't be 9 days. So anyways I'm all done, no yeast infection and no trich. Later, I found out it wasn't cervical cancer, it was just trich together with B.V. and the yeast infection that made it look like cancer cells. But thank God, till today, I'm all clear, no more unprotected sex..."

Metronidazole "Omg, reading all these comments scares me. The doctor prescribed the 4 pills to take at once. Two days it was clearing up. After my period came, the trich came back. I went to get retested and I'm now waiting for results, but I already know I still have this infection. This med should work the first time. I guess it's not strong enough to kill the infection in one or even two doses. I'm scared, and I hope it goes away soon."

"I was prescribed the 500 mg 2 times a day for 7 days. The pill didn’t even taste that bad, lol. The only side effect I had was dark urine and diarrhea, and that was on days 3 and 4. I’m approaching my 7th day with my last pill. So far, it’s been good. I do want to warn you that you might have discharge. It’s not always a yeast infection, it’s the medicine pushing the infection out."

"I was prescribed the one-time dose of four (4) 500mg tablets. Within hours, I noticed the horrible odor & discharge were totally gone!! I had been skeptical it would work well with just one dose but it's truly AMAZING!! I didn't have any of the (I personally think exaggerated) side effects some of these other reviews listed. I even took it on a completely empty stomach at the end of the day. No problems with the taste either as I take them differently than most people. I put water in my mouth, hold the water in my mouth without swallowing, tilt my head back (still not swallowing), drop the pills to the back of my throat & then swallow. I take many pills each day for various reasons & I've never tasted ANY pills that way."

"Update: Flagyl is rough to take, but it does the job for trich. Previously, I would never take Flagyl because of side effects, but I had to tough it out because it's one of the few used to treat it and options were minimal. One dose option did not cure me on two separate occasions. The 2-500 mg twice a day for 7 days did the trick. Lol. Don't miss a dose and finish all pills WITH FOOD to help with side effects. It will work if taken correctly, and don't read the bad reviews."

"It felt like metronidazole would kill me and not the bugs. Awful - four courses at different dosages and nothing. Tinidazole did the work in one treatment after suffering for months with metronidazole. Fewer side effects with tinidazole as well. A little more expensive, but it’s definitely worth it. Hope that helps someone who is struggling."

"Took the metronidazole 2g one-time dose with a full glass of water for trichomoniasis. Had some nausea about an hour later, but it went away when I ate. Noticed a change in discharge and odor the next day. HOWEVER, it's been a week, and I've noticed odor again, and I'm experiencing hip and lower back pain. I have not been sexually active, not sure what's going on!"

Metronidazole "I started the medicine and didn't have any side effects for up to three days, but after the third day, the side effects hit me big time. I was sick to my stomach, and I had vomiting. I didn't have a problem with the taste of the pill, I just threw it in the back of my throat and chugged some juice to make it go away really quickly. My infection seems to have cleared up after the first two days. No discharge or itching. Haven't had intercourse yet to see if the discomfort was gone, but will make another review when that happens. Great medicine!"

"Went for annual, found out I had trich, had no idea or symptoms. I was prescribed the four 500 mg in 1 single dose. After reading all of the reviews, I was basically terrified to take the medicine, so it took me a few days to get the courage to take it. I went out, ate a big dinner, took the med around 7:30 PM with a full bottle of water. I had minimum side effects: slight head fog, mild rumbling tummy, and insomnia that night. Next day, I was super tired, but in all honesty, the side effects I had were very easy to deal with. Praying it did its job when I go back to be retested, if it’s cleared up, I will post an update."

"Didn't have symptoms of trich until about a month after having unprotected sex. I went to the health department and tested positive for trich. The nurse was very thorough with the exam process and suggested that I get multiple STD tests to make sure I was not positive for anything else. In short, I took the 4 pills in 1 day. Actually, as protocol, the nurse had to observe me taking the medication. The pills worked, and I noticed a huge difference by the next day. I plan to do a follow-up to ensure I have been completely cured. ***PS- there are many complaints about the side effects of the antibiotics, but I would rather have the side effects than endure the horrible odor and other symptoms of trich."

Metronidazole "Was diagnosed with Trich. Dr. prescribed four 500 mg of Flagyl to take at once. Only complaint was metallic taste, but it made me drink water more often and chew minty gum - I survived. Unfortunately, it did not work. Six weeks and two days later, the discharge, itching, and symptoms returned. Note: I had not been intimate with anyone, so it was not because of sexual contact; Flagyl just didn't work. Returned to Dr., was retested, and it was positive for Trich. Dr. prescribed Tinidazole the second time, which I took yesterday; as soon as I reach or exceed 60-90 days with no symptoms, I will repost."

"I went to the clinic, and at first, they told me I had a UTI, and I got my medicine and felt better. But a week later, I had symptoms, and I went back, and apparently, I had a yeast infection. After that, I waited to see if it would clear, and it didn’t. I went back, and I tested positive for Trich, I got the 500 mg, 4 pills you take once. It worked so quickly, I stopped having discharge and less smell. I hope it goes away soon because it’s one of the most discomforting feelings ever, but I don’t know if I should go back just to check if everything is good and I don’t need more medication."

"I was prescribed the metronidazole 2g mega dose after testing positive for trichomoniasis (had symptoms of pelvic pain, cloudy urine, and pain during the swab test). I opted for the single dose instead of a week because I hate antibiotics! Was really anxious to take the medicine due to many reviews saying it made them ill. I had basically zero adverse side effects! Took the pills about 30 minutes after eating a full meal (I ate pasta and yogurt for dessert for the probiotics) and an hour before bed. Pills tasted bitter but nothing as bad as some reviews claim. Fell asleep with no problem. Had only a mild headache (if anything) the next day and no nausea. My symptoms (pelvic pain, pain during urination) seem to have stopped on day 2. Will get retested to be sure, but so far so good with this medicine! My advice: TAKE IT! Just eat 30 min before and stay hydrated! I also have been taking heavy-duty probiotics since to help rebuild the good bacteria."
