8 USE IN SPECIFIC POPULATIONS 8.1 PregnancyRisk SummaryLimited data from case series with tadalafil use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes.
- Tadalafil 40mg is a potent PDE5 inhibitor used for specific medical needs.
- Check expiration date before using to ensure medication efficacy.
- Avoid taking Tadalafil 40mg with fatty meals if concerned about absorption.
- Lifestyle modifications can enhance the effectiveness of Tadalafil treatment.

In animal reproduction studies, no adverse developmental effects were observed with oral administration of tadalafil to pregnant rats or mice during organogenesis at exposures 7 times the exposure at the maximum recommended human dose (MRHD) of 40 mg/day based on AUC (see Data).The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

In the U.S. general population, the background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.Clinical ConsiderationsDisease-Associated Maternal and/or Embryo/Fetal RiskPregnant women with untreated pulmonary arterial hypertension are at risk for heart failure, stroke, preterm delivery, and maternal and fetal death.DataAnimal DataTadalafil and/or its metabolites cross the placenta, resulting in fetal exposure in rats.Animal reproduction studies showed no evidence of teratogenicity, embryotoxicity, or fetotoxicity when tadalafil was given to pregnant rats or mice at unbound tadalafil exposures up to 7 times the exposure at the maximum recommended human dose (MRHD) of 40 mg/day during organogenesis based on AUC. In one of two perinatal/postnatal developmental studies in rats, a reduction of postnatal pup survival was observed at dose levels of 60, 200 and 1000 mg/kg. The no-observed-effect-level (NOEL) for developmental toxicity was 30 mg/kg, which provided maternal exposure to unbound tadalafil concentrations approximately 5 times the exposure at the MRHD based on AUC. Signs of maternal toxicity occurred at doses greater than 200 mg/kg/day, which produced AUCs greater than 8 times the exposure at the MRHD.

4.1 Concomitant Organic Nitrates
No dose adjustment is warranted based on age alone; however, a greater sensitivity to medications in some older individuals should be considered. [See Clinical Pharmacology (12.3)].8.6 Renal ImpairmentFor patients with mild or moderate renal impairment, start tadalafil tablets at 20 mg once daily. Increase the dose to 40 mg once daily based upon individual tolerability [see Dosage and Administration (2.2), and Clinical Pharmacology (12.3)].In patients with severe renal impairment, avoid use of tadalafil tablets because of increased tadalafil exposure (AUC), limited clinical experience, and the lack of ability to influence clearance by dialysis [see Clinical Pharmacology (12.3)].8.7 Hepatic ImpairmentBecause of limited clinical experience in patients with mild to moderate hepatic cirrhosis (Child-Pugh Class A or B), consider a starting dose of tadalafil tablets 20 mg once daily. Patients with severe hepatic cirrhosis (Child-Pugh Class C) have not been studied, thus avoid use of tadalafil tablets in such patients [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)]. Limited data from case series with tadalafil use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes.
Tadalafil for Erectile Dysfunction (ED)
In animal reproduction studies, no adverse developmental effects were observed with oral administration of tadalafil to pregnant rats or mice during organogenesis at exposures 7 times the exposure at the maximum recommended human dose (MRHD) of 40 mg/day based on AUC (see Data). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Disease-Associated Maternal and/or Embryo/Fetal Risk Pregnant women with untreated pulmonary arterial hypertension are at risk for heart failure, stroke, preterm delivery, and maternal and fetal death.
More common
Tadalafil and/or its metabolites cross the placenta, resulting in fetal exposure in rats. Animal reproduction studies showed no evidence of teratogenicity, embryotoxicity, sublingual tadalafil or fetotoxicity when tadalafil was given to pregnant rats or mice at unbound tadalafil exposures up to 7 times the exposure at the maximum recommended human dose (MRHD) of 40 mg/day during organogenesis based on AUC. Surviving offspring had normal development and reproductive performance. There are no data on the presence of tadalafil and/or its metabolites in human milk, the effects on the breastfed child, or the effects on milk production. When a drug is present in animal milk, it is likely that the drug will be present in human milk. Tadalafil and/or its metabolites are present in the milk of lactating rats at concentrations approximately 2.4-times that found in the plasma.
Possible Alternatives to Tadalafil
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for tadalafil tablets and any potential adverse effects on the breastfed child from tadalafil tablets or from the underlying maternal condition. Based on the data from 3 studies in adult males, tadalafil decreased sperm concentrations in the study of 10 mg tadalafil for 6 months and the study of 20 mg tadalafil for 9 months. There have been no studies evaluating the effect of tadalafil on fertility in men or women [see Clinical Pharmacology (12.2)]. Safety and effectiveness of tadalafil tablets in pediatric patients have not been established. Of the total number of subjects in the clinical study of tadalafil for pulmonary arterial hypertension, 28 percent were 65 and over, while 8 percent were 75 and over.
STORAGE & DOSAGE:
For patients with mild or moderate renal impairment, start tadalafil tablets at 20 mg once daily. Increase the dose to 40 mg once daily based upon individual tolerability [see Dosage and Administration (2.2), and Clinical Pharmacology (12.3)]. In patients with severe renal impairment, avoid use of tadalafil tablets because of increased tadalafil exposure (AUC), limited clinical experience, and the lack of ability to influence clearance by dialysis [see Clinical Pharmacology (12.3)]. Because of limited clinical experience in patients with mild to moderate hepatic cirrhosis (Child-Pugh Class A or B), consider a starting dose of tadalafil tablets 20 mg once daily. 10 OVERDOSAGE Single doses up to 500 mg have been given to healthy male subjects, and multiple daily doses up to 100 mg have been given to male patients with erectile dysfunction.

It is white to almost white powder that is practically insoluble in water, freely soluble in dimethyl sulfoxide and slightly soluble in methylene chloride.Tadalafil tablets, USP are available as white to off-white, oval shaped film coated tablets for oral administration. It is white to almost white powder that is practically insoluble in water, freely soluble in dimethyl sulfoxide and slightly soluble in methylene chloride. Pulmonary arterial hypertension is associated with impaired release of nitric oxide by the vascular endothelium and consequent reduction of cGMP concentrations in the pulmonary vascular smooth muscle. Inhibition of PDE5 by tadalafil increases the concentrations of cGMP resulting in relaxation of pulmonary vascular smooth muscle cells and vasodilation of the pulmonary vascular bed.Studies in vitro have demonstrated that tadalafil is a selective inhibitor of PDE5. PDE5 is found in pulmonary vascular smooth muscle, visceral smooth muscle, corpus cavernosum, skeletal muscle, platelets, kidney, lung, cerebellum, and pancreas.In vitro studies have shown that the effect of tadalafil is more potent on PDE5 than on other phosphodiesterases.

These studies have shown that tadalafil is greater than 10,000–fold more potent for PDE5 than for PDE1, PDE2, PDE4, and PDE7 enzymes, which are found in the heart, brain, blood vessels, liver, leukocytes, skeletal muscle, and other organs.
