I had a great experience with this drug, and would recommend it to anyone. The only downside is the cost, which can be prohibitive for some people.

Diclegis for Nausea and Vomiting of Pregnancy
Diclegis has been an absolute lifesaver for me. I was so sick starting at 4 weeks, and when I went to the doctor at 6 weeks she prescribed this medication. It's really helped me a lot; I only take two pills before bed and I feel fine all day long.

Diclegis for Nausea and Vomiting of Pregnancy
This drug is wonderful! I was feeling so sick during my first trimester, but after just one dose of this medicine, I felt great. It made such a big difference in how I was feeling that I could tell if I forgot to take a dose.

Diclegis for Nausea and Vomiting of Pregnancy
I'm on my third pregnancy, and as anyone who's been pregnant before knows, nausea is unfortunately a common symptom. I tried other treatments but found them to be ineffective. Diclegis has really helped me out and made it much easier to handle the nausea.

This treatment is fantastic. I feel great and have more energy. It's a nice reminder that pregnancy isn't always 9 months of feeling terrible.

Diclegis for Nausea and Vomiting of Pregnancy
I was struggling with nausea during my first pregnancy, to the point where I could only eat one meal a day. Once I started taking diclegis, I felt so much better! My friend who was on zofran had similar results; she found relief within hours of taking it.

Diclegis for Nausea and Vomiting of Pregnancy
This was prescribed for morning sickness and the sleeping part was a bonus. It kicked in really fast and has stopped my morning sickness completely. I'm only taking one instead of two like prescribed though because it knocks me out on just one.

Diclegis for Nausea and Vomiting of Pregnancy
The drowsiness this medication caused was really debilitating. I couldn't function at all while taking it, and it wasn't even safe for me to be driving or taking care of my child.

Diclegis for Nausea and Vomiting of Pregnancy
I was given this medication for nausea, and it did help with that. However, I felt incredibly exhausted after taking the first dose. To the point where I fell asleep while my toddler was playing (very unsafe). This continued even after a few more days of taking the medication, so I've decided to get rid of it.
2.3Patient Review

Diclegis for Nausea and Vomiting of Pregnancy
I'm on my second pregnancy and was prescribed this medication for severe nausea and vomiting. It worked great the first day, but I've slowly been getting worse over the past two weeks. I still vomit at least once a day and my nausea is all day long. I'm tired all the time and can barely find energy to play with my 2 year old.
2.3Patient Review

Diclegis for Nausea and Vomiting of Pregnancy
I would not recommend this medicine to anyone. I've been experiencing extreme mood swings and other unpleasant side effects for the last six hours, and it's supposed to last up to 12 hours.
