What is Exforge HCT used for?
- High blood pressure in adults
How Exforge HCT works
Exforge HCT is a combination of three medications that work together to lower blood pressure.
- Amlodipine is a calcium channel blocker (CCB). It works by relaxing your blood vessels to lower your blood pressure.
- Valsartan is an angiotensin II receptor blocker (ARB). It works by blocking angiotensin II, a hormone that's naturally found in the body. This helps relax your blood vessels so blood can flow through more easily.
- Hydrochlorothiazide is a thiazide diuretic (water pill). It works in your kidneys to remove extra water and certain electrolytes (like sodium and potassium). This lessens the amount of fluid that flows through your blood vessels, which helps lower blood pressure.

Pharmacist tips for Exforge HCT
- You can take Exforge HCT with or without food at any time of day. Taking the medication with food might help if it hurts your stomach.
- It's recommended that you check your blood pressure at home, write down your readings, and share your log with your prescriber at your follow-up visits. This helps your prescriber understand how well Exforge HCT is working for you and whether they need to recommend any dose changes.
- Be sure to make appointments for any blood work that your prescriber ordered. These blood tests check things like your electrolyte levels and kidney function to help make sure Exforge HCT is still safe for you to take.
- Take Exforge HCT exactly as prescribed. Don't lower your dose or stop taking the medication without talking to your prescriber first. This can cause your blood pressure to rise quickly. To prevent your blood pressure from changing too quickly, your prescriber might lower your dose slowly over time if you need dose adjustments or if you need to stop the medication.
- It's possible to feel dizzy when you start taking Exforge HCT and when your prescriber raises your dose. This side effect should lessen over time as you continue taking the medication. Stand up slowly or hold onto something when you stand from a sitting or lying down position. Call your prescriber if you feel dizzy, lightheaded, tired, or confused because your blood pressure might be too low.
- Try to avoid or limit how much alcohol you drink while you're taking Exforge HCT. Drinking on a regular basis, especially in high amounts, can cause higher blood pressure. Alcohol can also make side effects like dizziness and lightheadedness worse, which can sometimes lead to falls.
- Exforge HCT contains hydrochlorothiazide, which can make your skin more sensitive to sunlight. This might make it easier for sunburns to happen. It's a good idea to apply sunscreen and wear protective clothing when you go outside.
- Be sure to tell your care team about all of the medications you're taking, especially if you're taking other blood pressure medications or nonsteroidal anti-inflammatory drugs (NSAIDS). Exforge HCT can interact with many medications, so it's important for your care team to check that your medications are safe to take together.
- Don't take any potassium supplements, salt substitutes containing potassium, or other medications that raise potassium levels unless your prescriber instructed you to. Speak with your prescriber about whether you need to limit the amount of potassium-rich foods in your diet. Exforge HCT can cause changes to your potassium levels, and abnormal potassium levels can be harmful.
- Take any bile acid sequestrants, such as cholestyramine (Prevalite), at least 4 hours before or after Exforge HCT. These bile acid medications interact with Exforge HCT and cause less of your blood pressure medication to get absorbed into the body.
- It's important to add nutritious foods into your diet that are low salt and low fat while you're taking Exforge HCT. Be sure to include whole grains and a wide variety of vegetables. Ask your care team for more resources about the kinds of foods that can help lower your blood pressure.
Common questions about Exforge HCT
You might be able to take Exforge HCT if you have a sulfa allergy, but it depends on how severe your reaction to sulfa medications was in the past. Exforge HCT contains hydrochlorothiazide, which is a sulfa medication. But keep in mind that not all sulfa medications can cause the same allergic reaction. Let your prescriber know if you've had a reaction to sulfa-containing antibiotics, such as Bactrim (sulfamethoxazole / trimethoprim). Although it's unlikely that you'll be allergic to Exforge HCT, it's best to check with your care team if you can take this medication.
The most common side effect of Exforge HCT is dizziness. This is especially noticeable when you first start the medication and when the dose is raised. But it should get better over time as you continue taking Exforge HCT. Another side effect you might experience is swelling in the feet, ankles, legs, hands, or arms. Discuss with your care team about tips to ease any swelling, like keeping the swollen area raised or wearing compression socks. It's also possible to have headaches as a side effect of taking Exforge HCT. You might have less headaches as you continue taking the medication. Ask your care team about ways to manage headache, such as minimizing stress and staying hydrated.
Exforge HCT doesn't typically cause hair loss. Contact a healthcare professional if you notice hair loss while you're taking Exforge HCT. They can help you figure out what might be the cause of the hair loss.
In general, take Exforge HCT at the same time every day to keep the levels of medication in your body consistent. But it's not completely clear what specific time of day it's best to take your blood pressure medications. Some studies suggest that taking your medication at night can control blood pressure better. But findings from other studies aren't consistent with this effect. In addition, Exforge HCT contains hydrochlorothiazide, which can make you urinate; this is its way of getting rid of extra fluid in your body to lower your blood pressure. You might consider taking Exforge HCT in the morning or early afternoon to avoid waking up several times throughout the night to go to the bathroom. Talk with your prescriber if you have questions about when's the best time to take Exforge HCT.
No, it isn't safe to take Exforge HCT if you're pregnant. This medication contains valsartan, which can cause severe harm to an unborn baby if it's taken during pregnancy. In addition, Exforge HCT contains hydrochlorothiazide and amlodipine, which haven't been well-studied during pregnancy. Discuss with your prescriber about other blood pressure medications that are safer to take if you're pregnant or thinking of getting pregnant.
Yes, Exforge HCT is available as a lower-cost generic.
Both Exforge and Exforge HCT are combination blood pressure medications. They both contain amlodipine (a calcium channel blocker) and valsartan (an angiotensin II receptor blocker or ARB). But Exforge HCT also contains a third medication called hydrochlorothiazide (a thiazide diuretic or water pill). This is why the Exforge HCT brand name has "HCT" at the end of it. A healthcare professional might switch someone from Exforge to Exforge HCT if they need more blood pressure control since it has three different blood pressure medications in it.

Get medical help right away if you have chest pain, pressure in the chest, heartburn, dizziness, or trouble breathing.
Possible kidney damage in certain people
- Risk factors: Heart failure | Certain kidney problems | Dehydration | Taking other medications that can cause kidney damage
ARBs like valsartan (one of the ingredients in Exforge HCT) can protect the kidneys in some people. But it's also possible for the medication to affect the kidneys in a way that causes them to work less well. This can happen to anyone. But the effects can be more serious in people with severe heart failure, people with certain kidney problems, or people who take medications that can worsen kidney function.
Your primary care provider or cardiologist might order lab tests every so often while you're taking Exforge HCT. These lab tests make prescriber might recommend that you stop taking the medication if you develop kidney problems (or if your kidney problems worsen). Let your primary care provider or prescriber know if you're urinating less often than usual. This could be a sign that your kidneys aren't working as well.
Changes in electrolyte, blood sugar, and cholesterol levels
- Risk factors: Taking other medications that can change electrolyte, blood sugar, or cholesterol levels
Exforge HCT can affect the level of certain electrolytes, including sodium, potassium, and magnesium, in your body. Also, it can cause changes in your blood sugar levels. In addition, this medication can raise the levels of cholesterol and triglycerides (a type of fat).
You might need blood work done periodically while you're taking Exforge HCT to make sure your electrolyte, blood sugar, and cholesterol levels are in the normal range. Let your care team know about all the medications you take and plan to take with Exforge HCT because some medications can also cause similar changes. Tell your care team if you experience an abnormal heartbeat, weakness, low energy, muscle weakness or cramps, less urination than usual, nausea, or vomiting. These can be signs of electrolyte changes in your body.
Higher risk for gout
- Risk factors: Personal or family history of gout | Kidney problems
Exforge HCT can raise the uric acid levels in your body. This can cause or worsen gout. Your risk is higher if you've had gout attacks before or if you have problems with your kidneys. Talk to your prescriber right away if you notice that your joints are swollen, red, and painful.
Vision problems
- Risk factors: Sulfa or penicillin allergies
Although rare, some people experience vision changes or eye pain within hours or weeks after they start taking hydrochlorothiazide, which is found in the Exforge HCT combination medication. Tell your optometrist or prescriber right away about any vision changes or eye pain and stop taking Exforge HCT as soon as possible.
Lupus
- Risk factors: History of lupus
Medications containing hydrochlorothiazide like Exforge HCT can cause or worsen lupus. Talk to your prescriber if you have symptoms such as feeling very tired, joint pain, or a skin rash across your cheeks and nose.
