I recently started taking Prevymis (letermovir) 120mg Oral Pellets Pak to prevent cytomegalovirus (CMV) after my stem cell transplant. I'm wondering if anyone else has experience with this medication and how they've handled the potential side effects.

The FDA lists quite a few side effects to watch out for, including severe allergic reactions, abnormal heartbeats, and changes in urine output. I'm mostly concerned about the less urgent side effects like diarrhea and headaches. These can make everyday tasks difficult, but I'm not sure if it's worth stopping the medication.

I've also read that Prevymis can cause low blood cell counts, which increases the risk of infections and bleeding problems. I'm already immunocompromised, so this is a bit worrying. Has anyone else experienced this, and if so, how did you manage it? I'd appreciate any tips or advice on dealing with these potential issues.

Overall, I'm hoping to hear from others who have been on Prevymis to get a better understanding of what to expect. How long did it take for side effects to appear? Did they go away over time? Any insights would be greatly appreciated.

I've been on Prevymis for about six months after my stem cell transplant, and so far, so good. I've had a few minor side effects like upset stomach and diarrhea, but nothing too serious. I make sure to take it with food and stay hydrated, which seems to help. I'm just grateful that it's doing its job in preventing CMV. Stay strong, everyone!

I had a bad reaction to this medication, but if you can tolerate it, it seems to be effective at preventing CMV. But, it’s a must to stay in constant communication with your healthcare provider.

If you experience any severe side effects, do not hesitate to seek medical attention immediately. It's better to be safe than sorry.

I wish I had known about the potential for low blood cell counts. I ended up with a pretty severe infection and had to be hospitalized. My doctor had to adjust my dosage and closely monitor my blood cell counts. I recommend regular blood tests if you're on Prevymis.

I had a really rough time with Prevymis. The diarrhea was so bad that I had to stop taking it. My doctor switched me to a different medication, and I've been doing much better.
