Pregnancy and Ranitidine
Studies have been performed in lab animals using ranitidine doses of 160 times the normal human dosage. The results have shown no indication of damage to the reproductive organs or to the fetuses of these lab animals. There are, however, no adequate studies that have been performed among pregnant women, so precautions should be taken with this drug once a pregnancy is confirmed.
Many women stop taking previously prescribed medications during pregnancy, especially during the first and second trimesters due to fear of harming the healthy growth of the fetus. Be sure to consult your physician with your concerns about raniditine or any other drug.
On another note, ranitidine should not be taken if you have a history of liver or kidney problems. Some doctors have linked the risk of pneumonia with taking ranitidine.
Male Fertility and Ranitidine
Studies have been conducted on the effects of ranitidine and fertility in men. The conclusion of each study has been that there are not any significant changes in sperm concentration.
On the other hand, drugs like Tagamet, also used to reduce acid in the stomach, have been known to change sperm count. Pepcid, Axid, and Zantac are safer bets in getting rid of heartburn without causing any fertility issues in males, but always check with your doctor before changing medications.
Side Effects in Pregnant Women
If you have been taking ranitidine prior to conception, you may or may not have experienced side effects. However, after conception, you may notice some of the side effects become bothersome. Notify your doctor if you experience nausea, diarrhea, headaches, drowsiness, restlessness, dizziness, any type of skin rash, or if you have trouble sleeping.
