Understanding Valsartan-Hydrochlorothiazide

Before we delve into the main topic of this article, it's essential to understand what Valsartan-Hydrochlorothiazide is. It is a combination medicine used primarily to treat high blood pressure. Valsartan is an angiotensin receptor blocker that relaxes and widens your blood vessels to lower your blood pressure. On the other hand, Hydrochlorothiazide is a diuretic or "water pill" that helps prevent your body from absorbing too much salt, which can cause fluid retention. Now that we have a basic understanding of this drug, let's examine its implications during pregnancy.

Why Valsartan-Hydrochlorothiazide is a concern during Pregnancy

While Valsartan-Hydrochlorothiazide is effective in managing high blood pressure, it raises several concerns when used during pregnancy. The drug falls under the FDA Pregnancy Category D, implying that it can pose significant risks to the fetus. Valsartan, in particular, can cause harm or death to an unborn baby if taken during the second and third trimesters of pregnancy. As a result, it's crucial to consult your healthcare provider if you're pregnant or planning to become pregnant while on this medication.

Proven Risks of Valsartan-Hydrochlorothiazide during Pregnancy

Several studies have shown that using Valsartan-Hydrochlorothiazide during pregnancy can lead to adverse effects on the fetus. These include fetal and neonatal morbidity and mortality. The drug can interfere with the renin-angiotensin system, which plays a crucial role in kidney development in the fetus. Resultantly, it may lead to renal dysfunction, oligohydramnios, skull ossification, and even fetal death.

Healthcare Providers' Recommendations

Given the potential risks associated with Valsartan-Hydrochlorothiazide, healthcare providers often advise against its use during pregnancy. If you're already on the medication and become pregnant, your doctor will likely recommend discontinuing it as soon as possible. It's essential to have open and honest conversations with your healthcare provider about your plans for pregnancy to ensure appropriate medication management.

Alternative Medications for High Blood Pressure

If you're pregnant and need to manage high blood pressure, there are safer alternatives to Valsartan-Hydrochlorothiazide. These include medications such as Methyldopa, Labetalol, and Nifedipine, all of which fall under the FDA Pregnancy Category C or B, meaning they are considered safer during pregnancy. However, it's still important to discuss these options with your healthcare provider to determine the best course of action for you and your baby.

Non-Medication Alternatives

Aside from medication, there are numerous non-pharmacological ways to manage high blood pressure during pregnancy. Lifestyle modifications like regular physical activity, a balanced diet, limited salt intake, and avoiding alcohol and tobacco can significantly help control blood pressure. Stress management techniques such as meditation, yoga, and deep breathing exercises can also be beneficial.

Planning for Pregnancy on High Blood Pressure Medication

If you're on high blood pressure medication and planning for pregnancy, it's crucial to discuss this with your healthcare provider. They can guide you on how to safely manage your blood pressure during this time, including possibly switching medications or adjusting dosages. Remember, your health and the health of your unborn child should always be the priority.


While Valsartan-Hydrochlorothiazide is an effective medication for controlling high blood pressure, it is not recommended for use during pregnancy due to potential risks to the fetus. Thankfully, there are safer alternatives available, both in terms of medication and lifestyle changes. As always, it's best to consult with a healthcare provider when making any decisions about medication use during pregnancy.
