Morning sickness is a condition during pregnancy that causes nausea and vomiting. It usually begins around the sixth week of pregnancy, and continues until about the second trimester.
Despite its name, morning sickness can occur any time of the day or night. It’s most severe during the first trimester, but it isn’t always confined to that time. Many women can even have it all day long, and throughout the duration of their pregnancy.
Some women have very mild symptoms, while others can become more ill. Whilst many women can get relief from over the counter remedies, the most serious cases of morning sickness can require prescription treatments.
How common is morning sickness?
Morning sickness is a very common condition during pregnancy. About 70% of pregnant women will experience some level of morning sickness . Some women have it so severely that it progresses to a condition called hyperemesis gravidarum.
A pregnant woman with hyperemesis gravidarum may become dangerously dehydrated, or lose more than 5% of her body weight prior to pregnancy. In severe morning sickness cases, and for women suffering from hyperemesis gravidarum, treatment will often be necessary.

What causes morning sickness?
The causes of morning sickness aren’t fully understood, but a widely accepted theory is that it’s the increased hormones during the first trimester that cause the nausea and vomiting. Another potential cause of morning sickness is the hypersensitivity to smells that can happen during pregnancy.
What are the symptoms of morning sickness?
The symptoms of morning sickness are often consistent between different people. It usually involves nausea and vomiting that can be triggered by unpleasant smells, hunger, and increased saliva production caused by pregnancy. Some women can also experience morning sickness onset after eating certain foods that are spicy or sweet.
Can morning sickness lead to other problems?
Morning sickness doesn’t usually have any long term effects. It’s uncomfortable and inconvenient, but doesn’t harm the pregnant mother or unborn fetus in most cases, unless it progresses to hyperemesis gravidarum.
When you have hyperemesis gravidarum, the accompanying dehydration and weight loss can affect the health of both you and your baby. In the most severe cases, it can lead to hospitalisation. If your morning sickness or hyperemesis gravidarum is preventing you from keeping food or water down, talk to your clinician. There might be a treatment that can help you to control your symptoms.

What medications are there for morning sickness?
There are lots of available medications that can help you with the symptoms of morning sickness, and they can work in different ways. Some of them are marketed specifically for pregnant women with morning sickness, while others are general nausea medications that are prescribed for different conditions.
Doxylamine/Pyridoxine (Xonvea in the UK) is a prescription medication that’s marketed specifically for morning sickness. This combination medication includes two active ingredients: doxylamine succinate and pyridoxine hydrochloride. Other treatment options include Cyclizine, Metoclopramide, and Prochlorperazine.
Is there a ‘best’ treatment for morning sickness?
The best morning sickness treatment for you will depend on your needs. Your health history will help our clinician to determine which medications might be safest for you and your baby.
If you’re not sure which treatment option could be best for you, our experts can help you decide once you’ve talked to us about your health. Based on your medical history, symptoms and personal preferences, we can help to point you in the right direction.
Does morning sickness always need treatment?
You don’t always need to take prescribed medications to help with your morning sickness symptoms. Sometimes your symptoms can be helped by trying natural foods, some supplements or by adjusting your diet.
Some studies have suggested that ginger has the potential to provide relief from morning sickness, but research is still quite limited.
Most women will see their morning sickness symptoms resolve between weeks 16-20. If morning sickness symptoms go away fully during the second trimester, you shouldn’t need to continue any treatments or home remedies. Mild morning sickness symptoms might not require any intervention if they’re bearable, so you can choose whether or not you’d like to use any treatments based on your own comfort and needs.

Is morning sickness treatment safe?
Answer:
Medications to treat the symptoms of morning sickness are generally safe. Some people might prefer a medication like Doxylamine/Pyridoxine, because it’s formulated specifically for pregnant women. Other medications are also safe, but are more frequently used to treat nausea and vomiting caused by something else, like motion sickness or chemotherapy.
Does morning sickness treatment always work?
Answer:
Morning sickness treatments are effective, but results can vary. They can be highly effective for some women, but might not work as well for others.
Doxylamine/Pyridoxine has proven to be particularly effective for treating the symptoms of morning sickness. Pregnant women reported 68% reduced nausea while taking Xonvea and doctors rated this medication as 78% effective. Nearly 50% of women reported that they hadn’t vomited in five days or more while taking Xonvea.
Other nausea medications can also be effective. Combining these treatments with lifestyle changes and home remedies could increase relief from symptoms. Discuss the options with our clinician to determine which treatments could be best for you.
Do you need a prescription for morning sickness treatments?
Answer:
Most morning sickness treatments will require a prescription so that your clinician can monitor your condition. This is especially true for medications for pregnant women, because of the sensitive nature of pregnancy and the increased risk of health complications.
If you’re considering morning sickness treatments, talk to your clinician about the different options. They can determine which is most appropriate for you based on your medical history and personal preferences.
