No, you should not take Tizanidine while pregnant. Tizanidine is a muscle relaxant and it has been classified as a pregnancy category C drug by the FDA. This means that there are no adequate studies done on humans to prove its safety in pregnant women and also animal studies have shown adverse effects on fetal development when given this drug during pregnancy.

Therefore, taking this medication while pregnant can cause potential harm to the growing baby or even lead to birth defects. It is recommended for any woman who is planning to become pregnant or already pregnant to talk with her doctor about all of the risks associated with taking Tizanidine before considering using it during her pregnancy.

  • Talk to your doctor: Before taking any medication while pregnant, it is important to consult with a healthcare provider
  • Your doctor can provide advice on the safety of taking Tizanidine and any potential risks associated with the drug during pregnancy
  • Follow dosage instructions: Make sure you follow all of your doctor’s instructions carefully when taking Tizanidine while pregnant
  • Take only the amount prescribed by your physician at regular intervals until you finish the course of treatment as directed
  • Do not take more or less than what was recommended for you, as this may increase side effects and lessen effectiveness of the drug in treating muscle spasms related to multiple sclerosis (MS)
  • Monitor side effects: It is important to monitor for common side effects such as dizziness, drowsiness, weakness and nausea/vomiting when taking Tizanidine while pregnant so that these can be addressed promptly if they occur
  • Report symptoms immediately : If serious side effects such as difficulty breathing , chest pain or irregular heartbeat occur after starting medication , notify your healthcare provider right away

What should I think about if I’m taking pain medicine during my pregnancy?

What Pregnancy Class is Tizanidine?

Tizanidine is a prescription medication used to treat muscle spasms and pain caused by certain medical conditions. It belongs to the class of drugs known as centrally-acting skeletal muscle relaxants and is usually prescribed for short-term use. With regards to pregnancy, tizanidine falls into the FDA’s Pregnancy Category C – meaning that while animal studies have not shown any harm, there are no well-controlled studies in pregnant women; therefore it should be used during pregnancy only if clearly needed.

Women who are pregnant or planning to become pregnant should discuss with their healthcare provider all potential risks associated with taking tizanidine before starting treatment.

Can You Get a Relaxer While Pregnant?

No, it is not recommended to get a relaxer while pregnant. Relaxers contain harsh chemicals such as sodium hydroxide or guanidine carbonate which can be absorbed into the body and may lead to adverse health effects for both mother and fetus. In addition, these chemicals are known irritants that can cause skin reactions or other side-effects like headaches and dizziness.

Therefore, it’s best to avoid using relaxers during pregnancy as a precautionary measure.

Who Should Not Take Tizanidine?

Tizanidine should not be taken by anyone who is allergic to it or any of its ingredients. It should also be avoided in people with liver cirrhosis, kidney failure, depression, low blood pressure, and myasthenia gravis. Pregnant women or those breastfeeding should avoid taking tizanidine as the safety of this drug has not been established during these periods.

Additionally, elderly patients may need a dose adjustment due to a greater sensitivity to the effects of this medication. Before taking tizanidine, it is important for individuals to consult their healthcare provider about potential risks and benefits associated with its use.

Does Tizanidine Affect Fertility?

Recent research has shown that while tizanidine may have a minor effect on fertility in men, it is not considered to be clinically significant. Studies conducted using laboratory animals suggest that there could possibly be adverse effects of the drug on sperm count, motility and morphology, however these findings still need to be confirmed by further clinical studies. It should also be noted that tizanidine has not been studied for its effects on female fertility yet, so it is currently unknown if the same applies here.

Therefore, until more information is obtained from human-based studies it cannot conclusively said whether or not tizanidine affects fertility in humans.

Has Anyone Taken Tizanidine While Pregnant

It is important to note that Tizanidine has not been studied extensively in pregnant women, so the effects on a developing fetus are largely unknown. While anecdotal reports suggest that Tizanidine may be safe for pregnant women, it is best to consult with your healthcare provider before taking this medication while pregnant.


In conclusion, it is important to speak with a doctor before taking tizanidine while pregnant as the risks are still unknown. While there have been no reports of adverse effects in animal studies, more research needs to be done on humans to determine if and how tizanidine affects an unborn baby. It’s also essential for women who are considering becoming pregnant or already pregnant to discuss their medication use with a healthcare professional.

Ultimately, only your healthcare provider can determine the best course of action for you and your baby’s safety during pregnancy.
