Ramipril is the generic version of the brand-name drug Altace, which is used to treat high blood pressure (hypertension).

Ramipril also reduces the risk of a heart attack, stroke, and death in people age 55 and older and at high risk of a major cardiovascular event.

It also improves survival when a person’s heart is not able to pump enough blood to the body (congestive heart failure) after a heart attack.

Ramipril is in a class of drugs called angiotensin-converting enzyme inhibitors, or ACE inhibitors, which work by keeping blood flowing smoothly throughout the body.

Doctors sometimes prescribe ramipril off-label to treat people with other health conditions, such as kidney issues associated with scleroderma (hardening and thickening of the skin), diabetes, and the genetic disorder Alport syndrome.

The FDA approved Ramipril in 1991, and Pfizer manufactures the drug.

In 2012, the consumer watchdog group Public Citizen petitioned the FDA to add black-box warnings cautioning against the use of three hypertension drugs when used together: ACE inhibitors, including ramipril; angiotensin receptor blockers (ARBs); and aliskiren (Tekturna).

Studies show that the three drugs can combine to cause kidney failure, low blood pressure, and hyperkalemia (elevated blood potassium levels).

However, ramipril doesn’t currently have a black-box warning against its combined use with other hypertension drugs.

Ramipril Warnings

Ramipril carries a black-box warning because the drug may cause harm and death to a developing fetus. Do not take ramipril if you are pregnant or plan on becoming pregnant.

People who are hypersensitive to ACE inhibitors should not use ramipril.

Additionally, people with diabetes or kidney impairments should not take ramipril at the same time as aliskiren (Tekturna).

The use of ACE inhibitors, including ramipril, has been associated with the following health problems:

  • An increased risk of angioedema (swelling under the skin) in people with a prior history of the condition or people taking mTOR inhibitors (a class of anti-cancer medications). Depending on where it occurs, it can cause pain, and difficulty swallowing and breathing.
  • Impaired liver function and failure
  • Impaired kidney function
  • Neutropenia and agranulocytosis (conditions associated with low counts of neutrophils, a type of white blood cell)
  • Hypotension
  • Hyperkalemia

Pregnancy and Ramipril

Ramipril can harm a developing fetus, particularly when taken during the second and third trimesters.

Drugs like ramipril can reduce the kidney function of the unborn baby, as well as cause poor development of the baby’s lungs and bones.

Ramipril is also associated with numerous other problems for newborns, including death. Ramipril should not be taken if you are pregnant or plan on becoming pregnant.

Ramipril is excreted in human breast milk and should not be taken if you are breastfeeding.

Do High Blood Pressure Medications Cause Weight Gain?

High blood pressure medications — like other prescription drugs — cause unwanted side effects. They can leave you feeling tired and restless. Some of them may even interfere with your mental health and your weight.

These are the most common types of medications prescribed to treat high blood pressure, what can happen if you continue to gain weight while on medication, and what you can do about it.

The most common high blood pressure medications

Doctors usually first prescribe a diuretic to treat high blood pressure. These medications increase urination, which reduces blood volume and removes excess saltfrom the body. It’s especially effective for treating mild hypertension.

However, most people with high blood pressure require a combination of diuretics and beta blockers — especially if diuretics alone don’t reduce blood pressure.

Beta blockers work by opening up blood vessels and regulating your heart rhythm so your blood flows with less pressure through your arteries, lowering your blood pressure. The most commonly prescribed beta blockers used to treat high blood pressure include:

  • Acebutolol (Sectral)
  • Atenolol (Tenormin)
  • Bisoprolol fumarate (Zebeta)
  • Carvedilol (Coreg)
  • Metoprolol tartrate (Lopressor) and metoprolol succinate (Toprol-XL)
  • Nebivolol (Bystolic)
  • Penbutolol sulfate (Levatol)

Doctors also prescribe ACE inhibitors and other medications to treat high blood pressure depending on what’s causing you to remain hypertensive.

Fatigue and weight gain are both common side effects of high blood pressure medications.

Is gaining weight with high blood pressure dangerous?

It can be. Weight gain, overweight, and obesity are associated with an increased risk of high blood pressure and heart disease. The more you weigh, the harder your heart has to work to pump blood through more mass. This increases the rate at which your blood flows, causing a gradual rise in blood pressure.

High blood pressure medications such as beta blockers don’t usually cause more than a few pounds (sometimes up to five) of weight gain, according to Mayo Clinic.

However, continuing to follow an unhealthy diet or neglect exercise while on your medication could cause you to gain more weight. This won’t do much to help you control your blood pressure.

Beta blockers reduce high blood pressure. They aren’t prescribed to help you lose weight.

This is why your doctor’s recommendations for treating high blood pressure usually go beyond remembering to take your medication.

What to do if your medication is making you gain weight

If you’ve been prescribed a high blood pressure medication that is making you gain weight, it’s unlikely there are other treatment options your doctor can prescribe. Doctors often prescribe beta blockers to treat high blood pressure, for example, when previous treatments don’t work.

However, all medications that treat high blood pressure should always accompany positive lifestyle modifications. These are the habits that can help keep you at a healthy weight despite your medication’s unwanted side effect.

Your doctor and/or dietitian will likely recommend, in addition to taking your medication regularly as prescribed:

  • Following a nutritious diet that excludes excess refined sugar and salt
  • Remaining physically active on a consistent schedule (150+ minutes per week — not all at once!)
  • Practicing good “sleep hygiene”
  • Finding healthy ways to manage stress.

It is possible to lose weight and maintain a healthy weight if you have high blood pressure — even if your medication doesn’t seem to be on your side.

If you have concerns about your weight related to high blood pressure or other medical conditions, bring them up with your health care provider. This is a common struggle with practical solutions that work. They can help you come up with an individualized plan that will work best for you.

Altace Capsules



ALTACE (ramipril capsules) has been evaluated for safety in over 4,000 patients with hypertension; of these, 1,230 patients were studied in US controlled trials, and 1,107 were studied in foreign controlled trials. Almost 700 of these patients were treated for at least one year. The overall incidence of reported adverse events was similar in ALTACE (ramipril capsules) and placebo patients. The most frequent clinical side effects (possibly or probably related to study drug) reported by patients receiving ALTACE (ramipril capsules) in US placebo-controlled trials were: headache (5.4%), “dizziness” (2.2%) and fatigue or asthenia (2.0%), but only the last was more common in ALTACE (ramipril capsules) patients than in patients given placebo. Generally, the side effects were mild and transient, and there was no relation to total dosage within the range of 1.25 to 20 mg. Discontinuation of therapy because of a side effect was required in approximately 3% of US patients treated with ALTACE (ramipril capsules) . The most common reasons for discontinuation were: cough (1.0%), “dizziness” (0.5%), and impotence (0.4%). Of observed side effects considered possibly or probably related to study drug that occurred in US placebo-controlled trials in more than 1% of patients treated with ALTACE (ramipril capsules) , only asthenia (fatigue) was more common on Altace (ramipril capsules) than placebo (2% vs. 1%).


ALTACE Placebo
(n=651) (n=286)
n % n %
Asthenia (Fatigue) 13 2 2 1

In placebo-controlled trials, there was also an excess of upper respiratory infection and flu syndrome in the ramipril group, not attributed at that time to ramipril. As these studies were carried out before the relationship of cough to ACE inhibitors was recognized, some of these events may represent ramipril-induced cough. In a later 1-year study, increased cough was seen in almost 12% of ramipril patients, with about 4% of patients requiring discontinuation of treatment.

Heart Failure Post Myocardial Infarction

Adverse reactions (except laboratory abnormalities) considered possibly/probably related to study drug that occurred in more than one percent of patients and more frequently on ramipril are shown below. The incidences represent the experiences from the AIRE study. The follow-up time was between 6 and 46 months for this study.

HOPE Study:

Safety data in the HOPE trial were collected as reasons for discontinuation or temporary interruption of treatment. The incidence of cough was similar to that seen in the AIRE trial. The rate of angioedema was the same as in previous clinical trials (see WARNINGS).

Other adverse experiences reported in controlled clinical trials (in less than 1% of ramipril patients), or rarer events seen in postmarketing experience, include the following (in some, a causal relationship to drug use is uncertain):

Body As a Whole: Anaphylactoid reactions. (See WARNINGS.)

Cardiovascular: Symptomatic hypotension (reported in 0.5% of patients in US trials) (See WARNINGS and PRECAUTIONS ), syncope and palpitations.

Hematologic: Pancytopenia, hemolytic anemia and thrombocytopenia.

Renal: Some hypertensive patients with no apparent pre-existing renal disease have developed minor, usually transient, increases in blood urea nitrogen and serum creatinine when taking ALTACE (ramipril capsules) , particularly when ALTACE (ramipril capsules) was given concomitantly with a diuretic. (See WARNINGS.) Acute renal failure.

Angioneurotic Edema: Angioneurotic edema has been reported in 0.3% of patients in US clinical trials. (See WARNINGS.)

Gastrointestinal: Hepatic failure, hepatitis, jaundice, pancreatitis, abdominal pain (sometimes with enzyme changes suggesting pancreatitis), anorexia, constipation, diarrhea, dry mouth, dyspepsia, dysphagia, gastroenteritis, increased salivation and taste disturbance.

Dermatologic: Apparent hypersensitivity reactions (manifested by urticaria, pruritus, or rash, with or without fever), photosensitivity, purpura, onycholysis, pemphigus, pemphigoid, erythema multiforme, toxic epidermal necrolysis, and Stevens-Johnson syndrome.

Neurologic and Psychiatric: Anxiety, amnesia, convulsions, depression, hearing loss, insomnia, nervousness, neuralgia, neuropathy, paresthesia, somnolence, tinnitus, tremor, vertigo, and vision disturbances.

Miscellaneous: As with other ACE inhibitors, a symptom complex has been reported which may include a positive ANA, an elevated erythrocyte sedimentation rate, arthralgia/arthritis, myalgia, fever, vasculitis, eosinophilia, photosensitivity, rash and other dermatologic manifestations. Additionally, as with other ACE inhibitors, eosinophilic pneumonitis has been reported.

Fetal/Neonatal Morbidity and Mortality. See WARNINGS : Fetal/Neonatal Morbidity and Mortality .

Other: arthralgia, arthritis, dyspnea, edema, epistaxis, impotence, increased sweating, malaise, myalgia, and weight gain.

Post-Marketing Experience: In addition to adverse events reported from clinical trials, there have been rare reports of hypoglycemia reported during ALTACE (ramipril capsules) therapy when given to patients concomitantly taking oral hypoglycemic agents or insulin. The causal relationship is unknown.

Clinical Laboratory Test Findings

Creatinine and Blood Urea Nitrogen: Increases in creatinine levels occurred in 1.2% of patients receiving ALTACE (ramipril capsules) alone, and in 1.5% of patients receiving ALTACE (ramipril capsules) and a diuretic. Increases in blood urea nitrogen levels occurred in 0.5% of patients receiving ALTACE (ramipril capsules) alone and in 3% of patients receiving ALTACE (ramipril capsules) with a diuretic. None of these increases required discontinuation of treatment. Increases in these laboratory values are more likely to occur in patients with renal insufficiency or those pretreated with a diuretic and, based on experience with other ACE inhibitors, would be expected to be especially likely in patients with renal artery stenosis. (See WARNINGS and PRECAUTIONS.) Since ramipril decreases aldosterone secretion, elevation of serum potassium can occur. Potassium supplements and potassium-sparing diuretics should be given with caution, and the patient’s serum potassium should be monitored frequently. (See WARNINGS and PRECAUTIONS.)

Hemoglobin and Hematocrit: Decreases in hemoglobin or hematocrit (a low value and a decrease of 5 g/dl or 5% respectively) were rare, occurring in 0.4% of patients receiving ALTACE (ramipril capsules) alone and in 1.5% of patients receiving ALTACE (ramipril capsules) plus a diuretic. No US patients discontinued treatment because of decreases in hemoglobin or hematocrit.

Other (causal relationships unknown): Clinically important changes in standard laboratory tests were rarely associated with ALTACE (ramipril capsules) administration. Elevations of liver enzymes, serum bilirubin, uric acid, and blood glucose have been reported, as have cases of hyponatremia and scattered incidents of leukopenia, eosinophilia, and proteinuria. In US trials, less than 0.2% of patients discontinued treatment for laboratory abnormalities; all of these were cases of proteinuria or abnormal liver-function tests.
