He or she can review the potential risks to the fetus.
Treating side effects
- Ask your doctor or nurse about medicine that is available to help prevent or lessen nausea and vomiting.
- Mouth care is very important. Your mouth care should consist of gentle brushing with a very soft toothbrush and rinsing your mouth with a mixture of 1/2 teaspoon of salt or 1/2 teaspoon of baking soda (sodium bicarbonate) in 8 ounces of water. This should be done at least after every meal and at bedtime. Avoid mouthwash that contains alcohol. Avoid alcohol and smoking because they can irritate your mouth and throat.
- Vaginal lubricants can be used to lessen vaginal dryness, itching, and pain during sexual relations.
- Speak with your doctor or nurse if you plan to have children. Ask for information on sperm or egg banking.
