"Picked up a super bug after a 12 day stay in hospital. I was put on 2 previous antibiotics before they started me on Clarithromycin 500mg twice a day for 7 days. Clarithromycin had me feeling" cured" by day two but I intend to finish it. I had to adjust or discontinue 3 other meds while taking this antibiotic, to insure my heart would not race for no reason, and it has not. But I do experience cramps and diarrhea but found Omeprazole handled those horrid side effects ange and citrus juice helps with that greatly with the metallic taste in my mouth. Although I needed to make alot of adjustments, this is a fantastic antibiotic considering I have been battling this same bug since Feb 25 and it's now April 23 .. This is the only antibiotic that worked!"

"I was given this antibiotic for a chest infection and have stopped taking it as it made me feel so poorly. I had pains in my chest and my tummy, had diarrhea on the third day and became very anxious. I was due to take a sixth tablet last evening but I feel as if I am poisoning myself....I will let my body heal itself."

"I was put on amoxicillin initially for a severe chest infection and laryngitis, but it did nothing so was given Clarithromcyin 500g to be taken twice a day and oh my days this stuff might help with the infection but the side effects are ridiculous! The stomach cramps appear randomly along with awful nausea. Now I could cope with them but having gas all day and the unholy metallic taste in your mouth constantly; even rousing you from the little sleep you get in the first place is horrendous!!!! I’m glad I’m signed off from work otherwise I’d be a wreck! 3 more days then I’ll be saved. Hopefully I’ll never have to take these ever again in life!"

"It actually took me 2 days to start taking Clarithromycin, I read the reviews and become terrified. I went back to the pharmacy to ask if they had capsule form or if I could break it up. I was advised no. They told that they have l'tiquid form but I had to contact the GP again. I just thought I can wait I need to psych myself. I bought some apple juice and psyched my self and did it. I felt so proud as I find it difficult swallowing big tablets. 1st day good I could breath, second day no side effects as such, third day sleeping problems, 4th day insomnia and anxiety, 5 day insomnia, extreme anxiety, vivid dreams, uncontrollable thoughts of soon, extreme sore throat that left me awake all night I'm now on 6th day, I was going to stop, as I don’t want a secondary infection, pharmacist told me to continue so on day 6. It has not been easy but the sore throat, insomnia and excessive anxiety are horrendous."

"Bad taste in mouth can be helped in my opinion by sucking fruit pastilles, the ones with sugar on. Had this drug before. Smaller doses ok., but the 500mg x 2 per day is awful. Will not be prescribed with this again!!"

"Course - 2 tablets a day for 7 days. Noticed relief from this antibiotic after first tablet with no noticeable side effects. After second tablet got horrible taste in mouth straight away. On second day now, and horrible taste persists after 3rd tablet. And now I have nauseous feeling in stomach. I have option to defer to augmentin if I have bad side effects.. Will seriously consider switching if the side effects get worse..Summary - Great effectiveness, Bad side effects..."

"I was prescribed clarithromycin for a chest infection post COVID. Within hours of taking the first tablet I had extreme stomach pain, heartburn and diarrhoea. I figured I need to line my stomach next time and this helped a bit. Chest infection felt better by day 3 and while stomach side effects subsided a little they still continued every days I was taking the pills (7 days). These antibiotics made me feel worse than the chest infection! On day 4 I started getting an unpleasant taste in my mouth which 3 weeks later is still there."

"After using this medication a rash started on my chest which spread extensively over my torso within 48 hours. There are some spots on my arms and legs but mostly concentrated on my chest and back. I have also experienced persistent head aches. I've stopped taking the medication but it must take a while to leave the body as spots keep appearing 2-3 days after. My upper respiratory tract infection has improved and my asthma eased but the rash is very uncomfortable especially on 37*C days. I won't be taking it again."

"Took this antibiotic for post covid bacterial lung infection. It has cleared my infection but WOW I’ve never felt like that in my life, I ended up in an Ambulance twice with breathing difficulties because of an adverse reaction to the antibiotics. First day and night was ok then the nightmare started, no appetite , body aches, insomnia , night sweats, total delusions ( didn’t know we’re I was ) I've stopped then with one day to go as I can’t bear to do another night. Feel million times better since I stopped them"

"I have used all kinds of antibiotics for my bronchitis over the years. Clarithromycin is so far the most effective of all. Usually I am on Amoxicillin and it gives me slow recovery. I was recently given Augmentin which I never used before. Surprisingly it didn't work at all. My chest infection got worse after a week on Augmentin. Fortunately, the symptom totally disappeared after merely two days switching to Clarithromycin. I am also taking Lansoprazole at the same time for my stomach so I don't have any side effects on stomach. I sense a little bit bitter taste in the mouth in the morning. I can live with that."

"Ive had a chesty cough for 7 weeks, following a total hysterectomy my Hilar lymph node is enlarged in my right lung and Im exhausted from coughing. I was diagnosed with ovarian cancer and am waiting to start chemotherapy, which is being delayed due to my infection. I have had amoxicillin 500mg and Doxycycline 500mg, neither did anything. I'm now on 2 x 500mg Clarithromycin, I have had 5 tablets so far and have 9 to take. Within a few hours of taking this medicine, the heat in my throat and ears was tremendous, it felt like the drugs were fighting the infection. The vile metallic taste started by 3rd tablet, its worse than the taste I had during my chemotherapy for breast cancer. It won't seem to go, immense thirst and headaches too!!"

"I took this twice a day (500mg) for seven days and could not wait for the course to be over. I’ve never suffered from side effects to a medication before, but I had an awful headache from day 3 onwards and the metallic/bitter taste in my mouth was really awful and made me feel nauseous and affected my sleep. I’d request a different medication if you can!"

"GP is treating me for a respiratory infection and prescribed me 500mg of Clarithromycin twice a day for 7 days. These antibiotics are bad I’m sure. The first day wasn’t too bad but come day 2 the stomach pain, nausea, bitter taste, losing my sense of taste and chronic headaches had started. I’m on day 6 and still have these side effects along with breathlessness, terrible dizziness, anxiety and generally feeling like I’m not on this planet. My head feels like it doesn’t belong to me.. which I’m turn doesn’t help the anxiety side effects, vicious circle! I’m at a loose end but as I’ve only one day and my evening tablet to go I will persevere. I hope these side effects don’t continue for too long once I’ve finished the course or I think I may crack up!!"

"I was prescribed this antibiotic having had flu like symptoms with a high fever. Within an hour of taking it I had a horrid bitter bile taste in my mouth then felt as if I had been put on waltzer at the funfair and spun around 100 times, a terrible and restless night, the second night was slightly better and I'm about to embark on my third night, feeling extremely weak and listless - but as of this morning 36 hours later I can breathe to the bottom of my lungs for the first time in about 15 years. A tip for vile taste - slice a Granny Smith apple and nibble when needed. I'm going to try and grit my teeth and and complete the course as I had forgotten what it is like to properly fill my lungs"

"I've never written a review on a medication before but felt it was important to share my experience. I was prescribed this despite suffering from anxiety and it was the worst experience of my life. I became agitated, more anxious and had suicidal ideation. I got a second opinion from another GP who said it should not have been prescribed to me and took me off it. I would not recommend this medication for anyone with anxiety and being honest, not for anyone at all. Looking at the other reviews, it has caused psychosis in people who never had mental health issues prior to taking it. There are also clinical papers on this. As somebody else said in another review RUN from this medication."
