The bottom line No known interaction

We found no known interaction between Aspartic Acid and Verapamil in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Aspartic Acid and Verapamil

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Verapamil and Aspartic Acid in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Aspartic Acid at all — not against Verapamil, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What to actually watch for

What Verapamil’s Own FDA Label Lists

This is not an interaction — none of it involves Aspartic Acid. These are the most notable effects listed in the ADVERSE REACTIONS section of Verapamil’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 6 of them are worth acting on rather than waiting out — marked below.

  • A bowel blockage Worth acting on
  • A slow heartbeat Worth acting on
  • Heart failure Worth acting on
  • Raised blood pressure Worth acting on
  • Liver problems Worth acting on
  • A higher chance of infection Worth acting on
  • A stuffy or runny nose
  • Sore throat
  • Low blood pressure
  • Stomach upset

From the ADVERSE REACTIONS section of the FDA label for Verapamil. Read the label on DailyMed › Aspartic Acid’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Aspartic Acid side to compare — that is a limit of the record, not a statement that Aspartic Acid has no side effects.

Special populations

Aspartic Acid in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When used orally in amounts found in foods.

Pregnancy And Lactation Possibly Unsafe

When aspartic acid is used orally. In rodents, aspartic acid given orally within a few days of birth caused neuronal necrosis in the hypothalamus. This adverse effect was not seen in nonhuman newborn primates and has not been assessed in humans. Until more data is available, the Institute of Medicine (IOM) and the Food and Nutrition Board advise that pregnant or breast-feeding women avoid the use of aspartic acid.

From our pharmacist’s overview on the Verapamil page

“This is one of the longer interaction lists we publish, and with verapamil (Calan, Verelan) it warrants genuine care, starting with the ten major-rated entries. Verapamil lowers blood pressure and slows the heart, so most of the 295 ingredients on file either push that effect further than intended or change how much of the drug reaches…”

About Aspartic Acid

What is Aspartic Acid?

Aspartic Acid
  • Testosterone support
  • Athletic performance and muscle building
  • Energy and endurance
  • General amino acid supplementation

Aspartic acid is a common amino acid your body makes on its own and gets from protein-rich foods, so a true deficiency is rare. D-aspartic acid is heavily marketed for boosting testosterone and athletic performance, but the evidence is mixed and many studies show little or no lasting benefit. Talk with your pharmacist or doctor before using high-dose supplements.

Amino acid (made in the body and found in protein-rich foods) · Capsules, tablets, powders (D-aspartic acid and L-aspartic acid), found in protein supplements

An interaction check asks whether these two react with each other — it does not ask whether Aspartic Acid is a good idea for someone in your situation. Here is what our Aspartic Acid record says about it on its own.

Aspartic Acid: dosing

There is no official or standardized dose of aspartic acid for any health purpose. Doses used in studies of D-aspartic acid have varied, and the best amount (if any) is not established.Because dosing is uncertain, the safest approach is to follow the directions on the product label and not exceed them. More is not necessarily better, and very high doses may not help and could even work against you.

About Verapamil

What Is Verapamil Used For?

Brand names: Isoptin SR, Verelan, Isoptin, Calan SR, Verelan SR, Calan, Covera HS, Verap, Veramil

Verapamil tablets and film-coated tablets are used to treat angina — including vasospastic (Prinzmetal's) angina, unstable angina, and chronic stable angina — as well as certain abnormal heart rhythms (arrhythmias) and high blood pressure (essential hypertension). For arrhythmias, regular-release tablets are used alongside digoxin to control heart rate in atrial flutter or atrial fibrillation, and to help prevent episodes of paroxysmal supraventricular tachycardia (SVT), a type of rapid heartbeat.

Extended-release and sustained-release oral forms (tablets and capsules) are indicated specifically for high blood pressure. Verapamil hydrochloride injection is used in hospital settings for rapid conversion of SVT to normal rhythm and for temporary control of fast heart rates in atrial flutter or atrial fibrillation.

Most-Reported Side Effects for Verapamil

From FAERS, the FDA’s public side-effect reporting system (4,297 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dyspnea 352 reports
Nausea 351 reports
Dizziness 295 reports
